ATTINY1626-MU

The ATtiny1624/1626/1627 microcontrollers of the tinyAVR 2 family are using the AVR CPU with hardware multiplier, running at up to 20 MHz, with 16 KB Flash, 2 KB of SRAM, and 256B of EEPROM available in a 14-, 20-, and 24-pin package. The family uses the latest technologies from Microchip with a flexible and low-power architecture, including an Event System, advanced digital peripherals, and accurate analog features such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA).
