ATTINY1606-MF

Overview

The ATTINY1606-MF is an 8-bit AVR microcontroller from Microchip Technology's tinyAVR 0 series, designed for functional safety applications. It features a hardware multiplier and operates at frequencies up to 20 MHz. The device integrates 16 KB of Flash memory, 1 KB of SRAM, and 512 bytes of EEPROM. It includes a Configurable Logic Block (CLB) with 32 logic elements, multiple communication interfaces including I2C, SPI, and UART/USART, and a 12-channel 10-bit ADC. Powered by a 2.7V to 5.5V supply, it is housed in a 20-VQFN package.

Feature Summary

• Integrates a Configurable Logic Block (CLB) peripheral consisting of 32 logic elements for custom logic implementation without CPU intervention.
• Supports Functional Safety (FuSa) requirements within the tinyAVR 0 series architecture.
• Includes a hardware multiplier to accelerate arithmetic operations for real-time control applications.
• Offers rugged security features and low-power operation modes suitable for sensor and embedded systems.

Applications

• Cost-sensitive sensor nodes requiring local logic processing
• Real-time control systems utilizing hardware multiplication
• Functional safety compliant embedded devices
• Low-power IoT endpoints

Procurement Notes

Verify the specific suffix 'MF' corresponds to the 20-VQFN (3x3) package and tray packaging configuration as listed in official Microchip documentation. Confirm that the functional safety certification status aligns with your project's compliance requirements before procurement. Ensure voltage supply ranges match your system design constraints.

Selection Notes

Select this component when a balance of moderate program memory (16KB) and high-speed processing (20MHz) is required alongside configurable logic capabilities. It is suitable for designs needing hardware acceleration via the built-in multiplier. Consider the 20-pin form factor if board space is limited but sufficient I/O count is necessary for connectivity peripherals.

Part Context

This part belongs to the ATtiny1606 series within the tinyAVR 0 family. It shares architectural similarities with the ATtiny806 and ATtiny1604 but offers increased Flash capacity compared to the 8KB variants. The series emphasizes energy efficiency and compact integration for modern embedded applications.

Replacement Considerations

The ATTINY806-MF serves as a lower-memory alternative within the same package and pinout. For higher performance needs, the ATtiny1607-MF provides additional Flash and RAM while maintaining compatibility. Verify pinout and software compatibility when substituting within the tinyAVR 0 family.
