8-bit RISC Microcontroller featuring an AVR RISC CPU operating at a maximum clock frequency of 20MHz. This FLASH-programmable device offers 16KB of ROM and 2KB of RAM, with 54 I/O lines. It operates within an industrial temperature range of -40°C to 85°C, powered by a nominal 5V supply (4.5V to 5.5V). The microcontroller is housed in a 64-terminal PQFP package (S-PQFP-G64) with dimensions of 14 x 14 mm, and includes PWM channels and an ADC.
