Microchip Technology's ATMEGA644PA-PN is an 8-bit AVR RISC microcontroller featuring 64KB of FLASH program memory and 4KB of data RAM. This CMOS component operates at a maximum clock frequency of 20MHz and supports low-power modes. Connectivity options include dual USARTs, I2C, and SPI interfaces. The device is equipped with 32 general-purpose I/O lines, three 8-bit timers, and six PWM channels. For analog input, it offers an 8-channel 10-bit Analog-to-Digital Converter (ADC). Additional peripherals include a Brown-Out Detector (BOD), Comparator, Real-Time Clock (RTC), and Watchdog Timer (WDT). The ATMEGA644PA-PN is housed in a 40-pin PDIP package, suitable for industrial automation, consumer electronics, and medical devices. Its operating temperature range is -40°C to +105°C, with a supply voltage range of 3.0V to 5.5V.
