ATTINY1616-SF

Overview

The ATTINY1616-SF is an 8-bit AVR microcontroller from the tinyAVR® 1-series, operating at up to 20 MHz. It features 16 KB of self-programmable Flash memory, 2 KB of SRAM, and 256 bytes of EEPROM. The device includes a hardware multiplier, two-level interrupt controller, and single-cycle I/O access. It supports multiple clock sources including internal RC oscillators and external crystals. Key peripherals include one TCA, two TCBs, one TCD timer, an RTC, USART, SPI, TWI, three analog comparators, two 10-bit ADCs, and three 8-bit DACs. It utilizes a Single-pin Unified Program and Debug Interface (UPDI) for programming.

Feature Summary

• Integrates Core Independent Peripherals (CIPs) and an Event System for CPU-independent inter-peripheral signaling.
• Includes a Peripheral Touch Controller (PTC) supporting capacitive touch interfaces with Driven Shield+ technology.
• Features Configurable Custom Logic (CCL) with programmable look-up tables for custom logic implementation.
• Provides automated CRC memory scan capabilities for data integrity verification.

Applications

• Capacitive touch interface applications
• Low-power embedded control systems
• General-purpose industrial monitoring

Procurement Notes

Verify the specific suffix 'SF' against official Microchip documentation to confirm package type and temperature range specifications. Ensure compatibility with existing board layouts regarding the 20-pin SOIC footprint. Confirm that the UPDI interface requirements align with your debugging and programming infrastructure before finalizing procurement.

Selection Notes

Select this component for designs requiring efficient peripheral management through CIPs and event-driven architectures. Consider its low-power sleep modes and flexible clock options for battery-operated applications. Evaluate the available I/O lines and analog peripherals against system requirements to ensure adequate resource allocation for sensors and communication interfaces.

Part Context

This part belongs to the ATtiny1614/1616/1617 family within the tinyAVR® 1-series. These microcontrollers share a common architecture featuring the AVR processor with a hardware multiplier. They are designed for applications needing a balance of processing power, memory capacity, and peripheral integration in compact packages.

Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when considering alternatives from other manufacturers or different series within the same product line.
