ATtiny1614/1616/1617
Automotive
tinyAVR
®
1-series
Introduction
The ATtiny1614/1616/1617 Automotive are members of the tinyAVR
®
1-series of microcontrollers, using
the AVR
®
processor with hardware multiplier, running at up to 16 MHz, with 16 KB Flash, 2 KB of SRAM,
and 256 bytes of EEPROM in a 14-, 20-, or 24-pin package. The tinyAVR
®
1-series uses the latest
technologies with a flexible, low-power architecture including Event System and SleepWalking, accurate
analog features, and Core Independent Peripherals. Capacitive touch interfaces with driven shield are
supported with the integrated QTouch
®
peripheral touch controller.
