ATTINY88-MUR 12MHz 8KB 32-VQFN AVR MCU | Microchip (Tape & Reel)
부품 번호: ATTINY88-MUR ✓ 활성ATTINY88-MUR 개요
An AVR microcontroller is an 8-bit embedded-control semiconductor that combines a processor core, nonvolatile program memory, data memory and peripherals on one integrated circuit. Within the product hierarchy, ATTINY88-MUR belongs to the ATtiny family of compact microcontrollers. Its 28 I/O pins provide substantial connectivity for sensors, switches, indicators, actuators and small serial interfaces while maintaining a low component count.
Key verified features include up to 12MIPS throughput at 12MHz, eight 8-bit timer/counter registers, programmable watchdog operation and support for In-Circuit Serial Programming. The device combines a 10-bit ADC, SPI serial interface and debugWire debugging in a 5mm-square surface-mount package. These resources suit compact control systems requiring mixed digital and analog input without a larger microcontroller package.
The ATtiny48/88 family uses Microchip picoPower AVR architecture to balance processing capability with low-power operation. Because ATTINY88-MUR is an 8-bit device, firmware is best organized around interrupt-driven control, timers, digital state machines and periodic sensor sampling. The 512-byte SRAM should be budgeted carefully when buffering data or supporting multiple communication routines, while the 8KB flash capacity favors compact code and bootloading strategies.
Typical applications include small industrial controllers, building automation endpoints, sensor hubs, LED-control systems, appliance interfaces and compact embedded instruments. A designer can use the 28 GPIO pins for local controls while assigning SPI to an external sensor or display and using the ADC for analog measurement. Programming is supported through the device's programming and debug interfaces documented by Microchip.
A critical PCB consideration is exposed-pad and via layout in the 32-VQFN package. Confirm the exact land pattern, pad dimensions and pin mapping against the manufacturer package drawing before fabrication. Keep analog and digital return paths controlled, provide local supply decoupling, and use the reset and programming interface so programming and debugging remain accessible in production.

일반적인 애플리케이션
ATTINY88-MUR 적합 용도: 7 애플리케이션s: Industrial Sensor and Control Hub, Building Automation Endpoint, LED Lighting Controller, Appliance Interface Module, Battery-Powered Monitoring Device, Programmable Logic Controller, Compact Embedded Instrument.
Industrial Sensor and Control Hub
The ATTINY88-MUR fits compact industrial control nodes because its 28 general-purpose I/O lines can connect switches, discrete sensors, status indicators and actuator drivers while the 10-bit ADC handles supported analog inputs. Its 12MHz AVR core can execute interrupt-driven sampling and control logic at up to 12MIPS. With 8KB flash and 512 bytes SRAM, firmware should favor periodic measurement and state-machine processing rather than large buffering. Industrial designs should verify isolation, surge requirements and operating-temperature limits against the complete manufacturer data.
추천
Building Automation Endpoint
ATTINY88-MUR is suitable for a compact building-automation endpoint that coordinates inputs from room controls and outputs for relays, indicators or low-power actuators. Its 28 I/O lines reduce the need for external I/O expanders, while the 10-bit ADC can serve compatible analog sensing functions and SPI can connect a local display or sensor. The 1.8V to 5.5V operating range supports multiple embedded supply architectures. Firmware designers should use timers for periodic sampling and avoid exhausting the 512-byte SRAM with simultaneous communication buffers.
추천
LED Lighting Controller
The ATTINY88-MUR can serve as the local controller in a compact LED fixture because its timer/counters support timing functions and its 28 I/O pins provide ample connections for LED drivers, switches and status feedback. SPI may connect a compatible LED controller or display, while firmware can implement dimming, sequencing and fault indicators within the 8KB flash budget. For multi-channel lighting, calculate LED current separately because the MCU supply and GPIO ratings must not be treated as constant-current sources. Validate driver topology, thermal margins and dimming behavior on the assembled board.
추천
Appliance Interface Module
ATTINY88-MUR fits appliance interface modules that translate buttons, door switches, display commands and actuator requests into a compact embedded controller. Its 8-bit AVR architecture is appropriate for deterministic supervisory logic, and 28 I/O lines allow multiple discrete functions to share one device. The 64-byte EEPROM can support limited persistent settings, while the 10-bit ADC can monitor qualified analog signals. Designers should avoid treating EEPROM as bulk storage and should confirm endurance, retention and exact voltage requirements from the manufacturer documentation before assigning product parameters.
추천
Battery-Powered Monitoring Device
ATTINY88-MUR is appropriate for a small battery-powered monitor when its 1.8V to 5.5V range and picoPower AVR architecture align with the supply design. The device can use timers for periodic sensor sampling, GPIO for a low-duty-cycle status indicator and SPI for a compatible external sensor. Its 12MHz maximum clock offers processing headroom, although actual battery life depends more heavily on sleep strategy, peripheral shutdown, sensor duty cycle and regulator quiescent current. Validate low-voltage timing and retention behavior from the manufacturer datasheet before release.
추천
Programmable Logic Controller
The 28 I/O lines, two timer/counters and EEPROM make ATTINY88-MUR suitable for a small embedded PLC-like controller for pumps, lamps, relays or simple sequencing machines. Its 12MHz throughput is sufficient for deterministic instruction sequences and interrupt-based input handling, while the 10-bit ADC can support monitored process variables. Firmware should isolate timing-critical outputs, include watchdog recovery and constrain RAM-heavy functions. Industrial safety certification, isolated inputs and relay isolation are system-level requirements and must be added where required; the MCU qualification alone is insufficient.
추천
Compact Embedded Instrument
ATTINY88-MUR can act as the control and data-acquisition core of a compact instrument with switches, a display interface and analog inputs. The 10-bit ADC supports basic measurements, SPI can connect compatible sensors or storage, and the available I/O can handle keys, indicators and alarm outputs. Because SRAM is only 512 bytes, measurement routines should stream or summarize data rather than retain large sample arrays. Calibration constants, where applicable, must be stored in code, external nonvolatile memory or the limited EEPROM according to the product's retention requirements.

선택 가이드
주요 차별점
- High pin density for a compact 5mm-square microcontroller (vs ATtiny85-class devices)
- 12MHz processing and analog conversion in one device (vs ATTINY88-AU)
- Mixed peripheral integration for compact controls (vs ATTINY88-PU)
설계 노트
Use the exact manufacturer land pattern for the 32-VQFN, 5mm-square package and verify the exposed-pad connection against the official package drawing. Place input and output decoupling capacitors close to their assigned pins, preserve a low-impedance ground plane and route sensitive ADC inputs away from switching nodes. The verified search data confirms package size and pin count but not pad dimensions, so fabrication artwork must not be inferred from the generic QFN-32 library drawing.
Estimate the 5V rail current before selecting regulators and copper paths because the ATTINY88-MUR itself is only one part of the load. The verified operating range is 1.8V to 5.5V, while maximum clock rate is 12MHz; do not assume every operating point or peripheral combination is valid throughout the full range. Check the manufacturer's electrical characteristics, clock-speed limits and output-pin loading before selecting the supply voltage and external components.
Keep programming, reset and debug access available on the production PCB. ISP and debug signals should be routed to test pads or a connector without compromising analog signal integrity. For a mixed-signal design, assign ADC-capable pins according to the official alternate-function table, maintain a stable analog reference arrangement, and isolate SPI clock/data routing from sensitive inputs where practical. These steps reduce debugging and production rework risk.
Do not treat the 28 I/O count as the package pin count: ATTINY88-MUR has 32 package pins, including power, ground, reset and other device functions. Also avoid assuming a smaller-pin-count ATtiny package is a drop-in replacement. Firmware must budget the 512-byte SRAM carefully, and firmware-burning tools must match the MU suffix's official package and pin configuration.
