ATtiny1614/1616/1617 - Microchip Technology

1 ATtiny1614/1616/1617 tinyAVR 1-seriesIntroductionThe ATtiny1614/1616/1617 are members of the tinyAVR 1-series of microcontrollers, using the AVR processor withhardware multiplier, running at up to 20 MHz, with 16 KB Flash, 2 KB of SRAM, and 256 bytes of EEPROM in a 14-,20- and 24-pin package. The tinyAVR 1-series uses the latest technologies with a flexible, low-power architecture,including Event System, accurate analog features, and Core Independent Peripherals (CIPs). Capacitive touchinterfaces with Driven Shield+ and Boost Mode technologies are supported with the integrated Peripheral TouchController (PTC).

Downward migration may require code modification due to fewer availableinstances of some peripherals. Horizontal migration to the left reduces the pin count and, therefore, the available featuresFigure 2-1. tinyAVR 1-series Overview8 Pins20 24 14 8 KBFlash16 KB32 KB4 KB2 KBDevices described in this data sheetDevices described in other data sheetsATtiny3216 ATtiny3217 ATtiny1614 ATtiny1616 ATtiny1617 ATtiny412 ATtiny212 ATtiny414 ATtiny416 ATtiny417 ATtiny214 ATtiny814 ATtiny816 ATtiny817 Devices with different Flash memory sizes typically also have different SRAM and Configuration Peripheral SummaryTable 2-1.
