ATMEGA649-16AUR

The ATMEGA649-16AUR is an 8-bit AVR microcontroller from Microchip Technology based on the AVR enhanced RISC architecture. It delivers up to 16 MIPS throughput at 16 MHz, with 130 powerful instructions executing in a single clock cycle. The device features 64 KB of in-system self-programmable Flash memory, 4 KB internal SRAM, and 2 KB EEPROM with high endurance (10,000 Flash/100,000 EEPROM write/erase cycles).

This microcontroller is equipped with a rich set of peripherals including a 4x25 segment LCD driver, two 8-bit timers, one 16-bit timer, four PWM channels, an 8-channel 10-bit ADC, a programmable serial USART, master/slave SPI, and a universal serial interface with start condition detector. It also includes a programmable watchdog timer, on-chip analog comparator, and brown-out detection. Connectivity options include SPI, UART/USART, and USI.

The device operates over a supply voltage range of 2.7V to 5.5V and a temperature range of -40°C to 85°C. It is housed in a 64-TQFP package (14x14 mm) with surface mount mounting. The microcontroller features five sleep modes for power management: Idle, ADC Noise Reduction, Power-save, Power-down, and Standby. It includes an internal calibrated oscillator and supports JTAG interface for boundary-scan and programming.
