ATTINY3217-MFR Microcontroller 8-bit AVR MCU
The ATTINY3217-MFR is an 8-bit AVR tinyAVR™ 1-series microcontroller from Microchip Technology, designed for low-power, cost-effective embedded applications with advanced analog and digital peripherals. It features a high-performance AVR CPU running at up to 20 MHz, integrated with 32 KB in-system self-programmable Flash, 2 KB SRAM, and 256 bytes EEPROM, housed in a compact 24- VQFN package ideal for space-constrained designs. Operating from 1.8 V to 5.5 V across −40°C to +125°C, it combines robust functional safety features, low-power sleep modes, and capacitive touch sensing, making it suitable for industrial, consumer, and automotive applications.
ATTINY3217-MFR Key Features
It integrates a rich set of Core Independent Peripherals (CIPs) including a 12-channel 10-bit ADC, 8-bit DAC, analog comparators, and a Peripheral Touch Controller (PTC) supporting self/mutual-capacitance buttons and sliders without external components. The MCU includes multiple timers (1×12-bit TCD, 2×16-bit TCA/TCB), hardware multiplier, CRC scanner, windowed watchdog timer (WWDT), and safety mechanisms like POR, BOD, and VLM for reliable operation. Communication interfaces comprise SPI, I2C, and USART, while three low-power sleep modes (Idle, Standby, Power-Down) optimize energy efficiency for battery-powered devices.
