Microchip Technology, Inc. Microcontrollers ATMEGA644P-A15MZ

The ATmega644P-A15MZ is an 8-bit AVR microcontroller designed for automotive applications, compliant with AEC-Q100 standards. It features a high-performance, low-power architecture with a maximum throughput of 16 MIPS at 16 MHz. The microcontroller includes 64 KB of in-system self-programmable flash memory, 2 KB of SRAM, and 2 KB of EEPROM, with a write/erase endurance of 10,000 and 100,000 cycles respectively. This device supports various peripheral features, including two 8-bit timers, one 16-bit timer, six PWM channels, and an 8-channel 10-bit ADC with differential mode capabilities. It also offers multiple communication interfaces such as USART and SPI, along with a JTAG interface for programming and debugging. Operating voltage ranges from 2.7V to 5.5V, and it has low power consumption characteristics, with active mode drawing 8 mA and power-down mode consuming only 0.8 µA. The ATmega644P-A15MZ is available in a 44-pad QFN package, suitable for compact designs. This microcontroller is ideal for applications requiring robust performance and extensive peripheral support in automotive environments.
