ALIGNMENT AND ADJUSTMENT

SERVICE ADJUSTMENT

Lubrication The mechanical parts are factory coated with a thin coat of light grease and should not require further lubrication. If a light grease is applied, be careful not to get any grease on the play/record head or erase head, hubs, pulleys, tapes reels, drive belts, or switches. Use a good lubricant such as Silicon Lube G322L or Lubricate (00). Service Check Before aligning the mechanism, wipe off any accumulated dirt with denatured alcohol. Wipe around parts where the tape contacts and around all rotating parts. Drive belts are specially processed. Do not clean them with alcohol. Mechanical Torque Use a cassette type torque gauge and check the tape mechanism. Take-up torque 35 to 80 g-cm Rewind torque 65 g-cm min. Fast forward torque 65 g-cm min. Pinch Wheel Pressure No adjustment to the pinch roller spring is necessary. It should be sufficient to give at least 40 g-cm pull force. Tape Head Servicing Each time the unit is serviced, the face of all heads should be thoroughly cleaned with denatured alcohol or commercial head cleaning solution. The playback head should be demagnetized with a commercial demagnetizer. Accumulation of tape oxide during normal operations can cause problems, including loss of high frequencies and wow and flutter. Erase Head The erase head is properly aligned when the tape rides directly between the tape guide on the head without crinkling the tape.

AT27LV010A2

Atmels innovative design techniques provide fast speedsthat rival 5V parts while keeping the low power consump-tion of a 3.3V supply. At VCC = 3.0V, any byte can beaccessed in less than 70 ns. With a typical power dissipa-t ion of only 18 mW at 5 MHz and VC C = 3.3V, theAT27LV010A consumes less than one fifth the power of astandard 5V EPROM. Standby mode supply current is typi-cally less than 1 A at 3.3V. The AT27LV010A is available in industry standard JEDEC-approved one-time programmable (OTP) plastic PLCC andTSOP packages. All devices feature two-line control (CE,OE) to give designers the flexibil i ty to prevent buscontention.The AT27LV010A operating with VCC at 3.0V produces TTLlevel outputs that are compatible with standard TTL logicdevices operating at VCC = 5.0V. The device is also capa-ble of standard 5-volt operation making it ideally suited fordual supply range systems or card products that are plug-gable in both 3-volt and 5-volt hosts.Atmels AT27LV010A has additional features to ensurehigh quality and efficient production use. The Rapid Pro-gramming Algorithm reduces the time required to programthe part and guarantees reliable programming. Program-ming time is typically only 100 s/byte. The Integrated

Product Identification Code electronically identifies thedevice and manufacturer. This feature is used by industrystandard programming equipment to select the proper pro-gramming algorithms and voltages. The AT27LV010A pro-grams exactly the same way as a standard 5V AT27C010and uses the same programming equipment.

System ConsiderationsSwitching between active and standby conditions via theChip Enable pin may produce transient voltage excursions.Unless accommodated by the system design, these tran-sients may exceed data sheet limits, resulting in devicenon-conformance. At a minimum, a 0.1 F high frequency,low inherent inductance, ceramic capacitor should be uti-lized for each device. This capacitor should be connectedbetween the VCC and Ground terminals of the device, asclose to the device as possible. Additionally, to stabilize thesupply voltage level on printed circuit boards with largeEPROM arrays, a 4.7 F bulk electrolytic capacitor shouldbe utilized, again connected between the VCC and Groundterminals. This capacitor should be positioned as close aspossible to the point where the power supply is connectedto the array.

Note: 1. Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is VCC + 0.75V dc which may be exceeded if certain precautions are observed (consult application notes) and which may overshoot to +7.0V for pulses of less than 20 ns.

Notes: 1. X can be VIL or VIH.2. Read, output disable, and standby modes require, 3.0V VCC 3.6V, or 4.5V VCC 5.5V.3. Refer to Programming Characteristics. Programming modes require VCC = 6.5V.4. VH = 12.0 0.5V.5. Two identifier bytes may be selected. All Ai inputs are held low (VIL), except A9 which is set to VH and A0 which is toggled low

(VIL) to select the Manufacturers Identification byte and high (VIH) to select the Device Code byte.

Rapid Programming AlgorithmA 100 s PGM pulse width is used to program. Theaddress is set to the first location. VCC is raised to 6.5V andVPP is raised to 13.0V. Each address is first programmedwith one 100 s PGM pulse without verification. Then averification / reprogramming loop is executed for eachaddress. In the event a byte fails to pass verification, up to10 successive 100 s pulses are applied with a verification

after each pulse. If the byte fails to verify after 10 pulseshave been applied, the part is considered failed. After thebyte verifies properly, the next address is selected until allhave been checked. VPP is then lowered to 5.0V and VCC to5.0V. All bytes are read again and compared with the origi-nal data to determine if the device passes or fails.

AT27LV010A2

Atmels innovative design techniques provide fast speedsthat rival 5V parts while keeping the low power consump-tion of a 3.3V supply. At VCC = 3.0V, any byte can beaccessed in less than 70 ns. With a typical power dissipa-t ion of only 18 mW at 5 MHz and VC C = 3.3V, theAT27LV010A consumes less than one fifth the power of astandard 5V EPROM. Standby mode supply current is typi-cally less than 1 A at 3.3V. The AT27LV010A is available in industry standard JEDEC-approved one-time programmable (OTP) plastic PLCC andTSOP packages. All devices feature two-line control (CE,OE) to give designers the flexibil i ty to prevent buscontention.The AT27LV010A operating with VCC at 3.0V produces TTLlevel outputs that are compatible with standard TTL logicdevices operating at VCC = 5.0V. The device is also capa-ble of standard 5-volt operation making it ideally suited fordual supply range systems or card products that are plug-gable in both 3-volt and 5-volt hosts.Atmels AT27LV010A has additional features to ensurehigh quality and efficient production use. The Rapid Pro-gramming Algorithm reduces the time required to programthe part and guarantees reliable programming. Program-ming time is typically only 100 s/byte. The Integrated

Product Identification Code electronically identifies thedevice and manufacturer. This feature is used by industrystandard programming equipment to select the proper pro-gramming algorithms and voltages. The AT27LV010A pro-grams exactly the same way as a standard 5V AT27C010and uses the same programming equipment.

System ConsiderationsSwitching between active and standby conditions via theChip Enable pin may produce transient voltage excursions.Unless accommodated by the system design, these tran-sients may exceed data sheet limits, resulting in devicenon-conformance. At a minimum, a 0.1 F high frequency,low inherent inductance, ceramic capacitor should be uti-lized for each device. This capacitor should be connectedbetween the VCC and Ground terminals of the device, asclose to the device as possible. Additionally, to stabilize thesupply voltage level on printed circuit boards with largeEPROM arrays, a 4.7 F bulk electrolytic capacitor shouldbe utilized, again connected between the VCC and Groundterminals. This capacitor should be positioned as close aspossible to the point where the power supply is connectedto the array.

Note: 1. Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is VCC + 0.75V dc which may be exceeded if certain precautions are observed (consult application notes) and which may overshoot to +7.0V for pulses of less than 20 ns.

Notes: 1. X can be VIL or VIH.2. Read, output disable, and standby modes require, 3.0V VCC 3.6V, or 4.5V VCC 5.5V.3. Refer to Programming Characteristics. Programming modes require VCC = 6.5V.4. VH = 12.0 0.5V.5. Two identifier bytes may be selected. All Ai inputs are held low (VIL), except A9 which is set to VH and A0 which is toggled low

(VIL) to select the Manufacturers Identification byte and high (VIH) to select the Device Code byte.

Rapid Programming AlgorithmA 100 s PGM pulse width is used to program. Theaddress is set to the first location. VCC is raised to 6.5V andVPP is raised to 13.0V. Each address is first programmedwith one 100 s PGM pulse without verification. Then averification / reprogramming loop is executed for eachaddress. In the event a byte fails to pass verification, up to10 successive 100 s pulses are applied with a verification

after each pulse. If the byte fails to verify after 10 pulseshave been applied, the part is considered failed. After thebyte verifies properly, the next address is selected until allhave been checked. VPP is then lowered to 5.0V and VCC to5.0V. All bytes are read again and compared with the origi-nal data to determine if the device passes or fails.

High-voltage audio head selectionswitchBA7755A / BA7755AF

The standard audio circuits of video cassette recorders and the recording circuits of tape decks use AC bias record-ing to record the audio signal onto the tape. This bias voltage is some tens of volts, and a high-capacity bias-sideswitch is required to electronically switch the head when in playback or record mode.The BA7755A and BA7755AF are high-voltage switching ICs designed to switch voltages as high as 65VDC orAC120VP-P (f = 70Hz).Two control systems, one for current control, and one for voltage control are provided, so the ICs can be used in cir-cuits that employ either method.By combining the BA7755A or BA7755AF with the BA7751ALS recording / playback amplifier, it is possible to con-struct a compact recording / playback audio circuit. In addition, the BA7755A and BA7755AF are an excellent choicefor a wide variety of other high-voltage switching applications.

ApplicationsVideo cassette recorders and tape decks

Features1) High withstanding voltage ( 65VDC (Min.),

High-voltage audio head selectionswitchBA7755A / BA7755AF

The standard audio circuits of video cassette recorders and the recording circuits of tape decks use AC bias record-ing to record the audio signal onto the tape. This bias voltage is some tens of volts, and a high-capacity bias-sideswitch is required to electronically switch the head when in playback or record mode.The BA7755A and BA7755AF are high-voltage switching ICs designed to switch voltages as high as 65VDC orAC120VP-P (f = 70Hz).Two control systems, one for current control, and one for voltage control are provided, so the ICs can be used in cir-cuits that employ either method.By combining the BA7755A or BA7755AF with the BA7751ALS recording / playback amplifier, it is possible to con-struct a compact recording / playback audio circuit. In addition, the BA7755A and BA7755AF are an excellent choicefor a wide variety of other high-voltage switching applications.

ApplicationsVideo cassette recorders and tape decks

Features1) High withstanding voltage ( 65VDC (Min.),

AC120VP-P (Min.), f = 70Hz).2) Circuits for either current control or voltage control

are provided on the chip.3) Compact SIP 5pin or SOP 8pin package.
