Microchip Technology's ATMEGA645-16MI is an 8-bit AVR® ATmega microcontroller featuring a 16MHz core clock speed. This device offers 64KB of FLASH program memory with 32K x 16 organization and 4KB of SRAM. It includes 2KB of EEPROM for non-volatile data storage. The ATMEGA645-16MI supports multiple communication protocols, including SPI and UART/USART, along with a USI (Universal Serial Interface). On-chip peripherals include Brown-out Detect/Reset, Power-on Reset (POR), Pulse Width Modulation (PWM), and a Watchdog Timer (WDT). It also incorporates an 8-channel 10-bit Analog-to-Digital converter. With 53 general-purpose I/O pins and operating over a voltage range of 2.7V to 5.5V, this part is suitable for applications in industrial automation, consumer electronics, and automotive systems. The component is supplied in a 64-QFN (9x9) surface-mount package.
