ATTINY1626-SU

Overview

The ATtiny1626-SU is an 8-bit AVR microcontroller from the tinyAVR® 2 family, operating at up to 20 MHz. It features 16 KB of Flash memory, 2 KB of SRAM, and 256 B of EEPROM. The device provides 18 general-purpose I/O pins and includes a 12-bit differential ADC with 15 input channels. Communication interfaces include two USARTs, one SPI, and one TWI. It operates within a supply voltage range of 1.8 V to 5.5 V and is housed in a 20-pin SOIC package.

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 CPU-independent inter-peripheral signaling via the Event System.
• Integrates Configurable Custom Logic (CCL) with four programmable Look-Up Tables (LUT).

Applications

• Sensor nodes requiring efficient real-time control.
• Industrial applications with space constraints.
• Consumer electronics and home appliances.
• Automotive sensor interfaces.

Procurement Notes

Verify the ordering suffix 'SU' corresponds to the 20-pin SOIC package and standard temperature range (-40°C to +85°C). Confirm that the specific revision matches the datasheet DS40002234A. Ensure compatibility with UPDI programming interfaces for development and debugging.

Selection Notes

Select this model when 18 I/O pins are required, distinguishing it from the 14-pin ATtiny1624. It offers identical memory and peripheral counts to the 24-pin ATtiny1627 but with fewer available pins. Suitable for designs needing vertical migration within the tinyAVR® 2 family without code modification.

Part Context

Part of the tinyAVR® 2 family, which shares pin and feature compatibility across variants. The ATtiny1626 serves as the mid-range option between the 14-pin ATtiny1624 and the 24-pin ATtiny1627. All devices in this series utilize the same core architecture and peripheral set.

Replacement Considerations

ATtiny1624-SU: Fewer I/O pins (12 vs 18), same memory/peripherals. ATtiny1627-SU: More I/O pins (22 vs 18), same memory/peripherals. Both allow vertical migration without code changes.

FAQ
