ATTINY167-MMU

Overview

The ATtiny167-MMU is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features 16 KB of In-System Programmable Flash program memory, 512 bytes of EEPROM, and 512 bytes of internal SRAM. The device includes a 10-bit ADC with 11 single-ended channels and differential pairs, a LIN controller or UART, SPI, USI, and two timers/counters. Operating voltage ranges from 1.8V to 5.5V, with speed grades up to 16 MHz at 4.5V–5.5V. It utilizes a 32-pad VQFN package.

Feature Summary

• Advanced RISC Architecture with 32 general-purpose working registers for efficient code execution.
• Non-volatile memories including ISP Flash, EEPROM, and SRAM with high endurance ratings.
• Integrated communication peripherals supporting LIN 2.1/1.3, UART, SPI, and Universal Serial Interface.
• Low-power operation with multiple sleep modes and software-controlled clock switching.

Applications

• Embedded control systems requiring low power consumption
• LIN bus node applications in automotive environments
• General-purpose microcontroller tasks with analog signal processing needs

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing design constraints regarding voltage levels and interface requirements before procurement.

Selection Notes

Select this component for applications needing 16KB Flash and robust analog capabilities within a compact footprint. Consider the 16 MHz speed grade if operating above 4.5V. Evaluate power management features against system duty cycles.

Part Context

Part of the ATtiny87/167 family sharing hardware and software compatibility. Differs from the ATtiny87 primarily in having double the Flash memory size while maintaining identical peripheral sets and pin configurations across SOIC, TSSOP, and VQFN packages.

Replacement Considerations

ATtiny87 serves as a direct substitute if reduced Flash memory capacity is acceptable. Verify that the replacement meets all electrical and timing specifications required by the application design.
