ATTINY1617-MFR

The ATtiny1617-MFR is Microchip’s TinyAVR 1-series 8‑bit MCU. It uses the AVR RISC core for small, low‑power embedded tasks and comes in a compact package with configurable memory and peripherals. The MFR suffix denotes a specific package/temperature option; see the product page for exact package, voltage, and temp range.
Key features:
- Flexible clocking (internal/external) and multiple sleep modes.
- Peripherals: timers, PWM outputs, ADC, and serial interfaces (USART/SPI/I2C), plus an event system for peripheral-to-peripheral synchronization.
- Other: watchdog timer, brown-out detector, analog comparator; on‑chip RAM/Flash/EEPROM (sizes vary by variant).
Typical uses: small sensors, consumer devices, LED drivers, and other low‑power embedded tasks in a tiny footprint.
Development: Microchip Studio or PlatformIO/VSCode with the Microchip GCC toolchain. For exact specs of the MFR variant, consult Microchip’s datasheet/user guide.

Equivalent products (within Microchip AVR 1-series with similar features): ATtiny1607, ATtiny1614, ATtiny1615, ATtiny1616, ATtiny1627. They share the same core and peripherals; differences are flash RAM and pin count. For the same device in other packaging, use ATtiny1617-MU or other package variants of the 1617.
