ATTINY167-SU - 16MHz 16KB 8-Bit AVR MCU | Microchip
MPN: ATTINY167-SU ✓ NakahandaATTINY167-SU Ulas
An 8-bit AVR microcontroller is a compact semiconductor in the microcontroller hierarchy, combining a CPU core, program memory, data memory, I/O ports, timers, and communication peripherals on one integrated circuit. The AVR enhanced RISC architecture is designed for efficient control tasks, while in-system programming allows firmware to be written or updated without removing the device from its target circuit.
The ATTINY167-SU provides 16 KB of Flash for firmware, 512 bytes of EEPROM for nonvolatile parameters, and 512 bytes of SRAM for working variables. Its 16 general-purpose I/O lines support digital inputs, outputs, and multiplexed peripheral functions. A 16 MHz operating clock supports deterministic control in compact embedded products, and the 20-pin SOIC package simplifies assembly on conventional through-hole PCB layouts.
The device is based on the low-power CMOS AVR enhanced RISC architecture and integrates an 8-bit timer/counter with compare modes. Serial interfaces support communication with sensors, transceivers, actuators, and service connectors. Because Flash, EEPROM, SRAM, I/O, timing, and communications share one package, the ATTINY167-SU can reduce board area and component count compared with discrete control solutions.
Typical uses include LIN-connected automotive accessory modules, compact sensor interfaces, building-control nodes, lighting-control modules, and small industrial automation products. The combination of 16 KB Flash and a LIN controller is particularly useful in distributed networks where each node requires local firmware, nonvolatile configuration storage, and reliable low-speed communication.
When designing the PCB, assign every pin through the manufacturer pin-description table and reserve programming-test access for ISP programming and debugging. Follow the recommended input, output, and decoupling capacitor arrangement, and verify external clock requirements before selecting oscillator components. Because 512 bytes of SRAM is modest, use efficient buffers and avoid unnecessarily large in-memory data structures.
This product page combines the manufacturer specifications, package information, practical application guidance, and clearly qualified replacement analysis. The comparison and design notes focus on engineering differences that affect firmware compatibility, memory requirements, communications, layout, and production sourcing rather than simply repeating a catalog summary.

Tipikal na mga Gamit
ATTINY167-SU ay nararapat para sa 6 aplikasyons: LIN-Connected Automotive Control Node, Compact Sensor Interface, Industrial Building-Control Module, LED Lighting Controller, Battery-Powered IoT Endpoint, Embedded Serial Gateway.
LIN-Connected Automotive Control Node
The ATTINY167-SU fits distributed vehicle accessory modules that need local control, persistent configuration, and network communication without a large processor. Its integrated LIN controller and 16 general-purpose I/O lines can connect switches, sensors, lamps, and actuators, while 16 KB of Flash stores application firmware and 512 bytes of EEPROM holds calibration or configuration data. The 20-pin SOIC package also supports conventional automotive PCB assembly methods. Before production release, verify transient protection, operating-temperature requirements, AEC-Q100 status, and the diagnostic behavior required by the vehicle system.
Inirekomenda
Compact Sensor Interface
ATTINY167-SU is appropriate for a small sensor-conditioning node that must convert digital inputs, apply filtering, and communicate results over a serial link. Its 16 I/O lines allow connection of discrete sensors and control signals, while the 8-bit timer/counter with compare modes supports timing and measurement tasks. Sixteen kilobytes of Flash accommodates compact firmware, and EEPROM can preserve configuration values across power cycles. Because SRAM is limited to 512 bytes, the firmware should stream samples or use carefully bounded buffers rather than retaining large histories in memory.
Inirekomenda
Industrial Building-Control Module
The ATTINY167-SU can serve as the local controller in a compact building-control module for lighting, HVAC interfaces, occupancy inputs, or motorized outputs. Sixteen general-purpose I/O lines provide practical control and sensing capacity, and the integrated timer/counter supports repetitive switching and timing functions. The 16 MHz clock provides deterministic response for short control routines, while EEPROM stores operating schedules and configuration identifiers. Use a communications companion for longer network protocols because the controller's 512-byte SRAM and 16 KB Flash favor distributed tasks rather than gateway-scale applications.
Inirekomenda
LED Lighting Controller
ATTINY167-SU is well suited to LED lighting control when the design requires timed dimming, mode sequencing, local buttons, and status indication. The timer/counter and compare modes can generate repeatable timing sequences, while the 16 I/O lines support switch inputs and LED-control outputs. Firmware can store lighting scenes or calibration parameters in EEPROM, preserving settings after power loss. The device's 16 KB Flash and 512-byte SRAM are appropriate for compact controllers rather than graphics-heavy or highly connected lighting hubs. Validate drive-stage topology and thermal margins separately from the MCU supply design.
Inirekomenda
Battery-Powered IoT Endpoint
ATTINY167-SU can serve as a low-power IoT endpoint when the product uses a compact AVR-based design with intermittent operation and a modest firmware footprint. Sixteen I/O lines support sensors, pushbuttons, indicators, and a radio-control interface, while EEPROM retains device identity and operating configuration. The low-power CMOS AVR architecture is suitable for duty-cycled control, although the design must keep radio activity and sensor sampling outside long active periods. The 16 KB Flash limit favors lean protocol implementations, and the 512-byte SRAM requires streaming or small circular buffers.
Inirekomenda
Embedded Serial Gateway
The ATTINY167-SU is practical for a small protocol bridge or condition-monitoring node that converts a serial device stream into local control actions. Its serial communication resources and 16 general-purpose I/O lines allow it to coordinate sensors, indicators, and actuators, while EEPROM can hold routing configuration. The 16 MHz processing rate is appropriate for short frames and deterministic control logic rather than high-throughput protocol conversion. Because Flash and SRAM are constrained, use a bounded receive buffer, avoid deep logging, and place higher-bandwidth or heavily connected gateway functions on a more capable controller.

Talaan ng Disenyo
Use the manufacturer package drawing and pin-description table when assigning the 20-pin SOIC footprint. Keep power and ground connections short, place the required bypass capacitor close to the supply pins, and reserve the ISP programming signals so production programming does not require board modifications. Verify every alternate-function assignment against the device documentation rather than inferring pin names from an earlier ATtiny model.
Calculate the available operating margin from the minimum system supply voltage, maximum clock, peripheral activity, and I/O loading. The requested operating-voltage range is not stated on this product page, so confirm it in the manufacturer data sheet before selecting the supply source. Decouple the MCU rail close to the device and account for startup current when the board includes sensors, communication transceivers, or load switches.
Do not treat physical package equality as proof that replacement firmware is interchangeable. The ATTINY87 and ATTINY167 share a documented family, but instruction behavior involving JMP and RJMP differs. For any substitution, compare peripheral pin assignments, interrupt vectors, timer channels, communication features, register definitions, clock settings, and the compiled binary before releasing it for production.
Keep sensitive analog or communications routes away from switching nodes and high-current LED or actuator drive stages. If an external crystal or clock source is used, follow the layout and load-capacitance recommendations in the manufacturer data sheet. Provide local return paths for serial interfaces and place interface protection close to connector entry points so surge current does not flow through the MCU area.
