ATTINY167-XU

Overview

The ATtiny167-XU 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 within a voltage range of 1.8 V to 5.5 V with speed grades supporting up to 16 MHz at 4.5–5.5 V. The device includes a 10-bit ADC with 11 single-ended channels, a LIN controller, SPI, USI, and two timers. It utilizes a 20-pin SOIC or TSSOP package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• Integrated LIN controller and UART for serial communication
• On-chip debug system via debugWIRE interface
• Multiple power-saving modes including Idle and Power-down

Applications

• LIN bus node implementation
• Industrial control systems
• Battery-powered embedded devices
• Smart metering applications

Procurement Notes

Verify the specific suffix 'XU' corresponds to the required industrial temperature range and tape-and-reel packaging configuration. Confirm that the ordering code matches the exact pinout and memory size requirements for your design. Cross-reference the datasheet revision history to ensure compatibility with existing firmware development tools.

Selection Notes

Select this component when 16 KB of program memory is required alongside robust analog features. The XU suffix indicates availability in surface-mount packages suitable for automated assembly. Consider the 16 MHz maximum frequency if processing speed is critical within the specified voltage constraints.

Part Context

This part belongs to the ATtiny family of low-power 8-bit microcontrollers. It shares architectural similarities with the ATtiny87 but offers double the Flash memory capacity. The device is designed for cost-sensitive applications requiring high performance per watt.

Replacement Considerations

ATtiny87-XU serves as a hardware-compatible alternative with reduced Flash memory. Ensure software modifications are made if the application relies on the full 16 KB address space available in the ATtiny167.
