Data Sheets

CSE uses 3 main AVR processors:, the data sheets for these are stored locally on the links below.

For many purposes, the School has standardized on the AT Mega323 for general use. There are a couple of PCBs already developed for these controllers, with a reasonable sampling of existing code.

Mega64 - 53 I/O pins, 2 x UART, 8x10-bit ADC, timers, PWM, 64K Flash, 4K SRAM, 2K EEPROM
Mega323 - 32 I/O pins, UART, 8x10-bit ADC, timers, PWM, 32K Flash, 2K SRAM, 1K EEPROM
Mega32 - 32 I/O pins, UART, 8x10-bit ADC, timers, PWM, 32K Flash, 2K SRAM, 1K EEPROM
8535 - 32 I/O pins, UART, 8x10-bit ADC, timers, PWM, 8K Flash, 512 bytes SRAM, 512 bytes EEPROM
1200 - 15 I/O pins, 1 x timer, 1K Flash, no SRAM
ATmega8 - 16MHz, 18 I/O pins, UART, 6x10-bit ADC, timers, PWM, 8K Flash, 512 SRAM, 512K EEPROM

A document listing the assembly language instructions for the AVR family can be found in AVR_instructions.ps.gz

As well a number of other members of the family are used intermittently. Most tools will work acceptably on all members of the familt.
