ATTINY1626-SUR

Overview

The ATtiny1626-SUR is an 8-bit AVR microcontroller from the tinyAVR 2 family, featuring a 20 MHz CPU with hardware multiplier. It includes 16 KB of self-programmable Flash memory, 2 KB of SRAM, and 256 B of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports up to 18 general-purpose I/O pins. Key peripherals include a 12-bit differential ADC with PGA, two USARTs, SPI, TWI, and an Event System for low-latency inter-peripheral signaling.

Feature Summary

• Features a high-performance low-power AVR CPU running at up to 20 MHz with single-cycle I/O access and a two-cycle hardware multiplier.
• Includes advanced analog capabilities such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA) and multiple internal voltage references.
• Supports flexible system management through configurable custom logic (CCL), an event system for predictable peripheral signaling, and three distinct sleep modes.

Applications

• General purpose embedded control applications
• Intelligent sensing systems requiring accurate analog input processing
• Motor control and user interface implementations

Procurement Notes

Verify the specific ordering suffix 'SUR' corresponds to the SOIC-20 package and industrial temperature range (-40°C to +85°C). Confirm that the 'R' indicates Tape & Reel packaging if reel quantity is required. Ensure compatibility with existing designs by checking pinout alignment against the 20-pin variant specifications in the official datasheet.

Selection Notes

Select this component when vertical migration within the tinyAVR 2 family is desired without code modification. Choose this model over the ATtiny1624 or ATtiny1627 based on the requirement for exactly 18 I/O pins and 20-pin package availability. Consider the 12-bit ADC and Event System features for applications needing precise analog measurement and low-latency peripheral interaction.

Part Context

This device belongs to the tinyAVR 2 family, which utilizes the latest Microchip technologies for flexible and low-power architecture. The family offers horizontal migration options to reduce pin counts and vertical migration to increase features while maintaining pin and feature compatibility across the series.
