ATmega1284P_RESET


Crystal datasheet:Load capacitance CL = 7 pFESR 70kOhm Max.Frequency tolerance +/-20ppmDrive Level 1.0uW

ATmega1284P datasheet:Internal capacitance on each TOSC pin is Ci = 6pF

Ce = 2CL - Ci - Cs where: Ce - is the external capacitance neededCi - is the pin capacitanceCL - is the load capacitance specified by the crystal vendorCs - is the total stray capacitance

Cs is assumed to be <1pF and can be ignored

The estimated external capacitance needed can then be calculated:Ce = 2*7pF - 6pFCe = 8pFCe 8.2pF

Crystal datasheet:Load capacitance CL = 10 pF

ATmega1284P IBIS files:Internal capacitance on each XTAL pin is Cixtal1 = 4.3pF & Cixtal2 = 8.6pF

Cetot = Ci + CeCetot1 = Cixtal1 + Ce1Cetot2 = Cixtal2 + Ce2

To balance the external load Cetot1 has to be equal to Cetot2. Specifying Ce1 = 15pF (C5) resulting in:Cetot1 = 4.3pF + 15pF, Cetot1 = 19.3pFCe2 = 19.3pF - 8.6pFCe2 = 10.7pF, Ce12pF (C4)

We need a crystal with CL:CL = (Cetot1*Cetot2)/(Cetot1+Cetot2)CL = (19.3pF*20.6pF)/(19.3pF+20.6pF)CL = 9.96pF, CL10pF Cetot - is the total capacitance seen from the crystalCe - is the external capacitance neededCi - is the pin capacitanceCL - is the load capacitance specified by the crystal vendorCs - is the total stray capacitance(ignored)

This LED will be placed close to the QTouch button (less than 4mm away). To avoid detection instability due to the change in the LEDs capacitance between on and off states a capacitor in parallel with the LED is needed.

If the LED is always driven the capacitor is actually not needed. It's only needed when switching between output high and Hi-Z and low and Hi-Z.

This regulator can handle up to 18V input voltage and maximum 1.0A load current, with a maximum voltage drop of 1.4V. The output voltage is 3.3V ± 2%. The maximum quiescent current is 700µA. NOTE!! that worst-case output voltage may drop down to 3.0V with 4.4V input voltage.

USB 2.0 Input voltage specification: 4.4V - 5.25V, nominal 5.0V

NOTE!! ESR on output capacitor should be between 25mOhm and 22Ohm to maintain stable regulation. Higher values on the output capacitor will also improve loop stability and give better transient response which reduces output noise.

Crystal datasheet:Load capacitance CL = 20 pFESR 80 Ohm Max.Frequency tolerance 30 ppm

AT32UCB1 datasheet:Internal capacitance of the device is Ci = 12 pF

IBIS file (typical values):C_comp = 3.1 pFC_pkg = 0.2 pF

C = 2 ( CL - Ci ) - C_comp/2 - C_pkg/2C = 2 (20 - 12) pF - 1.5pF - 0.1pF = 14.6 pF

Load capacitance adjusted according to 18p after measurements on hardware.

220k NTC Temperature Sensor. Output will be 2.27V at 25C.Using the 2.56V bandgap as reference will result in 908 ADC codes.

Beta-formula:R1 = R2 * e^(B/T1-B/T2)

Ex. B(25/80):R = 220k * e^(4255/T1 - 4255/25)

1. order RC Lowpass filter with cut-off frequency at approximately 159 Hz.

To have constant DC values with low ripple, the capacitor/resistor values should be chosen to the minimum cut-off frequency.
