ATTINY167-A15MD

Overview

The ATtiny167-A15MD is an automotive-grade 8-bit AVR microcontroller featuring 16 Kbytes of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates within a voltage range of 2.7V to 5.5V, supporting speeds up to 16MHz at 4.5-5.5V or 8MHz at 2.7-5.5V across the -40°C to +125°C temperature range. The device includes a certified LIN controller, 10-bit ADC with differential channels, multiple timers, and DebugWIRE support.

Feature Summary

• Certified LIN 2.1 and 1.3 controller for automotive network communication
• Automotive quality grade verified per AEC-Q100 standards
• Advanced RISC architecture enabling single-cycle instruction execution
• Integrated analog comparator and on-chip temperature sensor

Applications

• Automotive body electronics control modules
• LIN bus node implementations
• Industrial embedded control systems
• Low-power sensor interface applications

Procurement Notes

Verify the specific suffix 'A15MD' against official Microchip documentation to confirm package type and temperature grade alignment. Ensure the source document explicitly supports the automotive qualification status for this exact part number before procurement.

Selection Notes

Select this component when automotive reliability under extended temperature ranges is required. It is suitable for applications needing certified LIN communication alongside standard serial interfaces like SPI and UART. Consider memory requirements as it offers double the Flash of the ATtiny87 variant.

Part Context

This device belongs to the ATtiny87/ATtiny167 family, which shares hardware and software compatibility. The primary distinction between these variants is program memory capacity, with the ATtiny167 providing 16Kbytes compared to the ATtiny87's 8Kbytes.

Replacement Considerations

The ATtiny87 is a pin-compatible alternative with reduced Flash memory. Verify if the application requires the full 16Kbyte capacity before substituting.
