ATTINY1626-MF

Overview

The ATtiny1626-MF is an 8-bit AVR microcontroller from the tinyAVR 2 family, featuring a 20-pin package with 16 KB of Flash memory, 2 KB of SRAM, and 256 B of EEPROM. It operates at a maximum clock frequency of 20 MHz within a supply voltage range of 1.8 V to 5.5 V. The device includes 18 general-purpose I/O pins, a 12-bit differential ADC with PGA supporting up to 15 channels, and multiple communication interfaces including USART, SPI, and TWI.

Feature Summary

• Features a high-performance low-power AVR CPU with hardware multiplier and single-cycle I/O access
• Includes advanced analog peripherals such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA)
• Supports flexible inter-peripheral signaling through the Event System and Configurable Custom Logic (CCL)
• Provides versatile connectivity via dual USART, SPI, and TWI interfaces alongside external interrupts on all pins

Applications

• Industrial control systems requiring robust peripheral integration
• Battery-powered devices utilizing low-power architecture and sleep modes
• Sensor interface applications leveraging the differential ADC and PGA capabilities
• Communication gateways using USART or TWI protocols

Procurement Notes

Verify the specific ordering suffix 'MF' against official Microchip documentation to confirm the exact package type and temperature rating. Ensure compatibility with existing board layouts by checking pinout configurations for the 20-pin variant. Confirm that the selected speed grade meets the operational requirements for the intended voltage and temperature environment.

Selection Notes

Select this component when vertical migration within the tinyAVR 2 family is required without code modification. Consider the ATtiny1626 over smaller variants if 18 I/O pins and 15 ADC channels are necessary. Evaluate the extended temperature range options if operation beyond standard industrial limits is required.

Part Context

This device belongs to the tinyAVR 2 family, designed for applications needing efficient code execution and advanced analog features. It shares architectural similarities with the ATtiny1624 and ATtiny1627, differing primarily in pin count and available I/O resources. The family emphasizes low power consumption while maintaining high performance through the optimized AVR CPU core.

Replacement Considerations

ATtiny1624-MF and ATtiny1627-MF are pin-compatible alternatives within the same family offering different pin counts.
