描述 Description

The ATmegaET64M1 is the extended temperature version of the popular Microchip ATmega64M1 8-bit AVR microcontroller.This high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller combines 64KB ISP flash memory with read-while-write capabilities, 2KB EEPROM, 4KB SRAM, 27 general purpose I/O lines, 32 general purpose working registers, one motor power stage controller, two flexible timer/counters with compare modes and PWM, one UART with HW LIN, an 11-channel 10-bit A/D converter with two differential programmable gain input stages, a 10-bit D/A converter, a programmable watchdog timer with internal individual oscillator, SPI serial port, an on-chip debug system, and four software selectable power saving modes.?By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.? With its CAN controller, power stage controller, ADC, DAC and analog comparators the ATmegaET64M1 microcontroller is a great choice for many of the most common space applications, which typically require a small footprint and low power. The device operates between 3-3.6 volts.
