ATTINY167-XUR

Overview

The ATtiny167-XUR is an 8-bit AVR microcontroller featuring 16 KB of In-System Programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at a maximum clock frequency of 16 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 10-bit ADC with 11 single-ended channels, a LIN/UART controller, SPI, USI, and two timer/counters. It utilizes a 20-pin SOIC package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Integrated LIN 2.1 and 1.3 Controller or 8-bit UART supporting serial communication protocols.
• On-chip debugWIRE system enabling single-pin programming and debugging capabilities.
• Multiple power-saving modes including Idle, Power-down, and ADC Noise Reduction.

Applications

• Embedded control systems requiring LIN bus connectivity
• Low-power industrial monitoring devices
• Battery-operated sensor nodes

Procurement Notes

Verify the specific suffix 'XUR' corresponds to the 20-pin SOIC package and industrial temperature grade as documented in the official Microchip ordering information. Confirm RoHS compliance status through the manufacturer's current datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component when 16 KB program memory is required alongside integrated LIN interface support. Ensure the design accommodates the 1.8 V to 5.5 V operating voltage range and utilizes the 20-pin SOIC footprint. Consider the 16 MHz speed grade relative to the target supply voltage constraints.

Part Context

This part belongs to the ATtiny87/167 family within the tinyAVR series. It shares hardware and software compatibility with the ATtiny87, differing primarily in having double the Flash memory capacity (16 KB vs 8 KB). Both devices utilize the same enhanced RISC core and peripheral set.

Replacement Considerations

The ATtiny87 is a direct functional substitute if reduced memory capacity is acceptable. Verify that the replacement part number matches the required package type and temperature rating.
