ATTINY167-SUR

Overview

The ATtiny167-SUR is an 8-bit microcontroller based on the AVR enhanced RISC architecture, featuring 16 KB of In-System Programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM. It includes a 10-bit ADC with 11 single-ended channels, a LIN controller or UART, SPI, USI, and two timers. The device operates at speeds up to 16 MHz within a voltage range of 1.8V to 5.5V and supports industrial temperature ranges.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Integrated non-volatile memories including ISP Flash, EEPROM, and SRAM with software security lock bits.
• Comprehensive peripheral set featuring a 10-bit ADC, analog comparator, and multiple communication interfaces.
• Supports low-power operation through Idle, Power-down, and ADC Noise Reduction sleep modes.

Applications

• Embedded control systems requiring efficient code execution
• LIN bus network node implementations
• Battery-powered devices utilizing low power consumption modes
• Industrial applications operating within extended temperature ranges

Procurement Notes

Verify that the ordering suffix corresponds to the specific package type required for your design, as the base part number covers multiple physical form factors. Confirm the speed grade matches your system's clock requirements. Ensure the component meets the necessary environmental specifications for your intended application environment before finalizing procurement.

Selection Notes

Select this model when 16 KB of program memory is required, distinguishing it from the hardware-compatible ATtiny87 which offers 8 KB. Consider the availability of the SUR package variant if surface mount assembly is preferred. Evaluate the peripheral count against project needs, noting the inclusion of both standard serial interfaces and specialized LIN capabilities.

Part Context

This component belongs to the ATtiny family of 8-bit microcontrollers manufactured by Microchip Technology. It shares architectural compatibility with the ATtiny87 but provides double the flash memory capacity. The device utilizes the AVR core technology designed to balance processing performance with energy efficiency for embedded control tasks.

Replacement Considerations

The ATtiny87 serves as a direct hardware and software compatible substitute if reduced memory capacity is acceptable. Verify that any replacement part maintains the same package dimensions and pinout configuration to ensure board compatibility without redesigning the PCB layout.
