ATTINY1617-MF

Overview

The Microchip ATTINY1617-MF is an 8-bit AVR microcontroller from the tinyAVR 1-series, housed in a 24-pin VQFN package. It features 16 KB of self-programmable Flash memory, 2 KB of SRAM, and 256 bytes of EEPROM. The device operates at clock frequencies up to 20 MHz with a supply voltage range of 1.8V to 5.5V. Key peripherals include a Peripheral Touch Controller (PTC), Event System, Configurable Custom Logic (CCL), and multiple timers including TCA, TCB, TCD, and RTC.

Feature Summary

• Integrated Peripheral Touch Controller (PTC) supporting capacitive touch buttons, sliders, wheels, and surfaces with Driven Shield+ technology for improved noise handling.
• Core Independent Peripherals (CIPs) such as the Event System and Configurable Custom Logic (CCL) enable predictable inter-peripheral signaling and CPU-independent operation.
• Comprehensive analog interface suite featuring two 10-bit ADCs, three 8-bit DACs, and three low-propagation-delay Analog Comparators.
• Single-pin Unified Program and Debug Interface (UPDI) simplifies programming and debugging connections.

Applications

• Capacitive touch user interfaces for consumer electronics
• Low-power embedded control systems requiring core-independent peripheral processing
• Industrial monitoring applications utilizing analog sensing and event-driven logic

Procurement Notes

Verify the specific suffix 'MF' against official Microchip documentation to confirm the exact package type and temperature grade. Ensure compatibility with the required voltage levels and clock speeds for your target application environment before finalizing procurement.

Selection Notes

Select this component when a compact 24-pin form factor is required alongside significant Flash capacity for complex firmware. The inclusion of dedicated touch controllers and advanced analog peripherals makes it suitable for applications needing direct sensor interfacing without external support chips.

Part Context

This device belongs to the tinyAVR 1-series family, designed for high performance and low power consumption. It shares architectural similarities with other members like the ATtiny1614 and ATtiny1616 but offers distinct pin counts and I/O configurations suited for different board space constraints.

Replacement Considerations

Check for pin-compatible alternatives within the same series, such as the ATtiny1616 or ATtiny3217, ensuring that memory sizes and peripheral sets meet the specific design requirements.
