ATtiny1624/1626/1627 tinyAVR 2 Family Introduction 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 Event System, advanced digital peripherals, and accurate analog features such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA). tinyAVR 2 Family Overview The figure below shows the tinyAVR 2 family devices, laying out pin count variants and memory sizes. Vertical migration is possible without code modification, as these devices are fully pin and feature compatible Horizontal migration to the left reduces the pin count and, therefore, the available features Figure 1.tinyAVR 2 Family Overview Devices described in this data sheet Devices described in other data sheets Flash 32 KB ATtiny3224 ATtiny3226 ATtiny3227 16 KB ATtiny1624 ATtiny1626 ATtiny1627 ATtiny824 ATtiny826 ATtiny827 8 KB ATtiny424 ATtiny426 ATtiny427 4 KB Pins 14 20 24 Devices with different flash memory sizes typically also have different SRAM and EEPROM.

This identifier is used for ordering purposes. Check with your Microchip Sales Office for package availability with the Tape and Reel option. Note: The VAO variants have been designed, manufactured, tested, and qualified in accordance with AEC-Q100 requirements for automotive applications. These products may use a different package than non-VAO parts and can have additional specifications in their Electrical Characteristics.
