Description

General part information

ATTINY3217 Series

The ATtiny3217 series of microcontroller features the 8-bit AVR® processor with hardware multiplier, running at up to 20 MHz and with up to 32 KB Flash, 2 KB SRAM and 256B of EEPROM in a 24-pin package. The series uses the latest Core Independent Peripherals with low-power features. It also includes an Event System, intelligent analog and advanced peripherals. Capacitive touch interfaces with proximity sensing and driven shield are supported by the integrated QTouch® Peripheral Touch Controller (PTC).

**Functional Safety**:

This product is recommended for [safety-critical applications](https://www.microchip.com/en-us/products/microcontrollers-and-microprocessors/8-bit-mcus/functional-safety), targeting industrial and automotive products (IEC 61508 and ISO 26262). Necessary documentation, such as the FMEDA report and Safety Manual, can be provided on request. The MPLAB X IDE and the [MPLAB XC8 compiler](https://www.microchip.com/en-us/development-tool/sw006021-fs) is available as a safety certified version. Contact your local Microchip sales office or your distributor for more information.
