ATTINY417-MFR

Overview

The ATTINY417-MFR is an 8-bit AVR microcontroller from the tinyAVR 1-series, packaged in a 24-pin VQFN. It features 4 KB of self-programmable Flash memory, 256 bytes of SRAM, and 128 bytes of EEPROM. The device operates at clock frequencies up to 20 MHz with a supply voltage range of 1.8V to 5.5V. It includes a 10-bit ADC, a single-channel 8-bit DAC, and multiple communication interfaces including USART, SPI, and TWI.

Feature Summary

• Integrated Capacitive Touch Controller (PTC) for touch sensing applications
• Configurable Custom Logic (CCL) utilizing programmable look-up tables
• Event System (EVSYS) enabling CPU-independent peripheral signaling
• Single-pin Unified Program and Debug Interface (UPDI)

Applications

• Capacitive touch interface designs
• Low-power embedded control systems
• Industrial monitoring devices

Procurement Notes

Verify the specific suffix 'MFR' against official Microchip documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with existing design files by cross-referencing the pinout and electrical characteristics with the ATtiny417 datasheet DS40001901C.

Selection Notes

Select this component when a compact 24-pin package is required alongside integrated capacitive touch capabilities. It is suitable for applications needing efficient event-driven processing via the EVSYS and CCL peripherals without continuous CPU intervention.

Part Context

This part belongs to the tinyAVR 1-series family, which emphasizes low power consumption and advanced peripheral integration. The series utilizes the AVR processor core enhanced with hardware multipliers and flexible architecture options for various industrial and consumer applications.

Replacement Considerations

ATtiny817-MFR offers identical pinout and features but provides 8 KB of Flash memory and 512 bytes of SRAM instead of 4 KB and 256 bytes respectively.
