ATMEGA88-20PU

8-bit RISC Microcontroller featuring an AVR RISC CPU operating at a maximum clock frequency of 20MHz. This CMOS device offers 4096 words of FLASH program memory and 1024 bytes of RAM, with 23 programmable I/O lines. Packaged in a 28-pin PDIP (R-PDIP-T28) with a 0.300-inch width, it supports PWM channels and includes an ADC. Operating within an industrial temperature range of -40°C to 85°C, it requires a supply voltage between 4.5V and 5.5V, with a nominal 5V.
