ATTINY167-MU

Overview

The ATtiny167-MU is an 8-bit AVR microcontroller featuring 16K bytes of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates within a voltage range of 1.8V to 5.5V with maximum clock speeds up to 16MHz at the upper voltage limit. The device includes a LIN controller, 10-bit ADC with 11 single-ended channels, two 8-bit timers, one 16-bit timer, SPI, USI, and USART interfaces. It utilizes a VQFN-32 package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrated LIN 2.1 and 1.3 controller for automotive network communication
• Advanced RISC architecture executing most instructions in a single clock cycle
• On-chip debug system (debugWIRE) for programming and debugging via SPI
• Multiple power-saving modes including Idle, ADC Noise Reduction, and Power-down

Applications

• Automotive applications requiring LIN bus communication
• Industrial control systems operating in harsh environments
• Battery-powered devices utilizing low-power consumption modes
• Embedded systems needing high-performance code execution efficiency

Procurement Notes

Verify the specific speed grade suffix matches the required operational frequency for your target voltage. Confirm the MU suffix corresponds to the VQFN-32 package type. Ensure the component meets RoHS compliance requirements for your manufacturing process. Check for any specific revision errata regarding crystal oscillator gain control if using external crystals.

Selection Notes

Select this model when 16K Flash memory is required compared to the 8K variant. Choose the VQFN-32 package for compact surface-mount designs. Consider the integrated LIN controller if automotive networking is necessary. Verify that the 16MHz speed grade is sufficient for the application's processing demands at the chosen supply voltage.

Part Context

This component belongs to the tinyAVR 1-Series family, specifically alongside the ATtiny87. Both share identical hardware and software compatibility, differing only in Flash memory capacity. The ATtiny167 provides double the program storage while maintaining the same peripheral set and pinout configurations across SOIC, TSSOP, and VQFN packages.

Replacement Considerations

ATtiny87-MU offers identical functionality with 8K Flash instead of 16K.
