contents 1. Introduction

This manual will guide you through the installation of the M35080 eraser/programmer,

referenced hereafter as the M35080 Programmer. The M35080 Programmer has been designed for on-board and ICP (in-circuit programming) modes via PC control operation for reading all EEPROM data, incremental area EEPROM writing, EEPROM writing, erasing data to delivery state of M35080 SPI EEPROM memory with incremental registers area.

2. Check list and Requirements Hardware requirements Host - A 32-bit x86 based with a free Serial port (Com1, 2) a hard-disk system. Memory - Minimum 16 Mbytes Display - Color VGA display recommended Power supply - A 12-14 volt/300 mA linear power supply source Tool - M35080 ERASER/Programmer board* Cable - An RS232C “straight-thru” cable* Adapters - four 8-pins SMD adapters* Software checklist OS - MS-Windows (Win95, Win98, Win2000, WinXP) Software tool - - ETL M35080 control software* * Package check list Contents: -M35080 eraser/ programmer board set included: - M35080 eraser/programmer board ** - 9-pin “straight-thru” cable ** - (4 pc.) 8 pins SMD adapters ** - CD (included control software) ** - This manual ** **NOTE: See M35080 ERASER/PROGRAMMER Package check list

3. Installing The M35080 Programmer is designed to accept M35080 8 Kbit Serial SPI Bus EEPROM with Incremental Registers. M35080 Programmer support both 2,5 and 5,0 MHz Clock Rate IC’s (See Appendix1). To understand M35080 Programmer components meaning see Figure 1. To install and use the M35080 Programmer, follow these steps:

• Install M35080 control software. Insert the supplied ETL CD-ROM in the computer and navigate to “Install Software” > “Install M35080 Prog.”, then execute the “Setup.exe” file; this will guide you through the setup process.

NOTE: M35080 control software, version 2.0 or later is required new M35080 ICP interface


board. Don’t use version 2.0 to communicate old hardware (See Appendix1). • Connect M35080 Programmer to the power supply source (12-14 V >=500 mA). • Attach M35080 Programmer to computer. Use the 9-pin RS232C cable that is shipped with

the M35080 Programmer. • Before connecting M35080 Programmer in ICP mode or inserting target IC M35080, make

sure that M35080 Programmer and the target board are not powered. NOTE: Only one mode (on-board or ICP) should be used during operate at a time. Don’t use at the same time programmer with inserted M35080 IC in the target socket and ICP mode. When you using ICP mode make sure, that target socket is empty. When you using target socket make sure that ICP interface not connected.

• Insert explored M35080 IC into target socket or connect ICP interface cable. • M35080 control software can now be started. However, do not open control software and any

files before connecting power supply to M35080 programmer. • Turn ON power switch. All LED’s appear to the short time, than LED1 (Yellow) will now be

lit, telling that power is present and M35080 Programmer ready to operate.

4.2 Write EEPROM command button Write operation will execute every time when user click “WRITE” command button. During this operation the LED2 will illuminate continuously in red until the EEPROM contents taken form the 24C08 (address $0020 to $3FF) have been copied to the M35080 (address $0020 to $3FFF). NOTE: Don’t forget to save previous data from the M35080 to the 24C08 storage memory. Click “READ” data first, than click “EEPROM Dump - > PC file” command buttons.

Figure 5. Write EEPROM area operation 4.3 Write Incremental Registers command button Write Incremental Registers operation will execute every time when user click “WRINC” command button. During this operation the LED2 will flash red until the EEPROM contents, taken from the 24C08 storage memory (address $0000 to $001F), have been copied to the incremental registers of the M35080 (address $0000 to $001F).

Figure 6. Write Incremental Registers area operation

NOTE: Don’t forget to save previous data from the M35080 to the 24C08 storage memory. Click “READ” data first, than click “EEPROM Dump - > PC file” command buttons. For writing a lower value to the incremental registers in the M35080 you must erase the registers before Write Incremental Registers area operation /“WRINC”/ !!!


4.4 Erase Incremental Registers command button Erase Incremental Registers operation will execute every time when user click “ERASE” command button. During this operation the LED1 will flash until erasure is compete. Once the erase operation is completed the LED1 will illuminate in yellow with the following flash sequence: one long delay, 3 medium delays then continuous yellow lit. The M35080 is now reset to blank factory delivery state condition***.

Figure 7. Erase Incremental Registers area operation

NOTE: Don’t forget to save previous data from the M35080 to the 24C08 storage memory. Click “READ” data first, than click “EEPROM Dump - > PC file” command buttons. *** The device is erased with the memory array in a fully erased state. With the exception of the first 32 bytes, all data bits are set to ‘1’, and hence all data bytes are at FFh. The first 32 bytes set to all ‘0’s, and hence the first 16 words at 0000h. The status register bits are initialized to ‘0’s, except for bit 4, which is set to ‘1’. 4.5 PC communication 4.5.1 Uploading a file from your PC (Writing data). Click “EEPROM Dump < PC File” command button and follow the program prompts. Select the input file. Wait until the busy window is present and LED2 slightly flashing. When the data has been written all LED’s appear during short initialization time, then LED1 appear again continuously will illuminate continuously. M35080 programmer is ready for its next operation. 4.5.2 Downloading a file to your PC (Saving data). Before click “EEPROM Dump > PC File” command button don’t forget click “READ” command button first, making sure that data is copied from the M35080 into the 24C08 memory. Now click “EEPROM Dump > PC File” command button, follow the program prompts, enter a file name. Wait until the busy window is present and LED3 slightly flashing. When the data has been saved all LED’s appear during short initialization time, then LED1 appear again continuously will illuminate continuously. M35080 programmer is ready for its next operation.

Figure 10. M35080 on-board and ICP interfaces The M35080 programmer send data to P2 connector via buffered interface (See Figure 10). Power supply voltage to target board feed from M35080 programmer board. Make sure that explored board has no over current problems. If you can’t read/erase/write M35080 IC on target board and no way to locate the problem just remove IC from target board and use on-board programming mode. Use correspond programming adapter (See Figure 3 in section 4)

NOTE: Only one mode (on-board or ICP) should be used during operate at a time. Don’t use at the same time programmer with inserted M35080 IC in the target socket and ICP mode. When you using ICP mode make sure, that target socket is empty. When you using target socket make sure that ICP interface not connected.

6. Dump viewer Click “Dump” menu item to enter dump viewer mode. Click “Open” menu item to review a dump contents. Memory address space display in HEX format only. Use scroll bar to navigate highest addresses. Click on cell byte to edit data into cell. When cell appear to red color enter new value into editor cell box, then press “Enter” on PC keyboard. Now edited cell appear to blue color.

APPENDIX 2 Autonomous Erase Incremental Registers command execution: Autonomous erase mode allows erase M35080 Incremental Registers area without PC connection. Follow next steps to enter autonomous erase mode:

• Insert explored into IC (M35080) Target IC socket (see Figure 1) • Unmount (remove) JP1 Option jumper (see Figure 1, Figure 16) • Turn ON Power Switch (see Figure 1, Figure16)

During this operation the LED1 will flash until erasure is compete. Once the erase operation is completed the LED1 will illuminate in yellow with the following flash sequence: one long delay, 3 medium delays then continuous yellow lit. The M35080 is now reset to blank factory delivery state condition.
