ATTINY1626-XU

Overview

The ATtiny1626-XU 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 PGA supporting 15 input channels. Connectivity options include two USARTs, one SPI, and one TWI interface. It operates within a voltage range of 1.8 V to 5.5 V and supports industrial temperature ranges.

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) and scalable analog comparator.
• Supports CPU-independent inter-peripheral signaling via the Event System and configurable custom logic.
• Offers flexible clocking options including internal oscillators and external crystal support for precise timing.

Applications

• Real-time control systems requiring efficient processing
• Sensor nodes utilizing integrated analog signal conditioning
• Industrial applications needing robust communication interfaces
• Space-constrained embedded designs

Procurement Notes

Verify the specific ordering suffix 'XU' corresponds to the TSSOP or SSOP package type as defined in the datasheet nomenclature. Confirm that the required temperature grade matches the standard -40°C to +85°C range associated with this suffix. Ensure compatibility with existing design tools and programming interfaces before finalizing procurement.

Selection Notes

Select the ATtiny1626-XU when 18 I/O pins are required alongside 16 KB of program memory. This model bridges the gap between the 14-pin ATtiny1624 and the 24-pin ATtiny1627. Consider its pin and feature compatibility with other tinyAVR® 2 devices for potential future migration paths without code modification.

Part Context

This component belongs to the tinyAVR® 2 family, which emphasizes vertical migration capabilities. It shares architectural similarities with the ATtiny1624 and ATtiny1627, differing primarily in pin count and available I/O resources. The family utilizes a unified programming interface and consistent peripheral sets across variants.

Replacement Considerations

The ATtiny1624-XU serves as a downward-compatible alternative with fewer pins. The ATtiny1627-XU offers additional I/O capacity. Verify pinout compatibility and memory requirements when substituting these members of the same family.
