ATTINY88-AU - 8-Bit 12MHz AVR MCU, 8KB Flash | Microchip
MPN: ATTINY88-AU ✓ AktifATTINY88-AU Ringkasan
An 8-bit AVR microcontroller is a programmable semiconductor containing a CPU core, flash program memory, data memory, peripheral modules, and I/O pins. The ATTINY88 belongs to the ATtiny family, uses the AVR enhanced RISC architecture, and is positioned as a low-power, cost-conscious embedded controller. Its 8-bit architecture is suited to control loops, sensor reading, actuator signaling, and simple serial communication rather than high-throughput computing.
Key verified features include 8 KB flash configured as 4K x 16 words, 512 bytes SRAM, 64 bytes EEPROM, 28 I/O lines, 32 general-purpose working registers, two flexible timer/counters with compare modes, an 8-channel 10-bit ADC with gain stage, I2C, SPI, and operation from 1.8 V to 5.5 V. The 12 MHz device combines a 7 x 7 mm TQFP package with sufficient peripheral integration for compact embedded products.
The AVR RISC architecture supports instruction-level efficiency, while the analog and serial peripherals reduce the need for external components. The ADC provides a practical path for analog sensor conditioning and control decisions, while I2C and SPI support communication with sensors, displays, memories, and other digital peripherals. The timers support timing, input capture, compare, and PWM-style functions.
Typical applications include small sensor nodes, LED lighting controllers, compact consumer devices, battery-powered accessories, simple data-acquisition modules, and low-cost embedded control boards. The 1.8 V to 5.5 V operating range supports systems built around modern low-voltage digital rails.
When designing around the ATTINY88-AU, confirm pin multiplexing, ADC input availability, programming signals, and power requirements against the manufacturer datasheet. Firmware and toolchain compatibility should also be validated before production release.

Aplikasi Umum
ATTINY88-AU cocok untuk 7 aplikasis: Compact Sensor Node, LED Lighting Control, Battery-Powered Accessory, Simple Data Acquisition Module, Industrial Control Interface, Consumer Device Controller, Low-Cost Educational Controller.
Compact Sensor Node
The ATTINY88-AU fits compact sensor nodes because it combines an 8-channel 10-bit ADC with 28 general-purpose I/O lines and 8 KB of flash in a 32-TQFP package. A designer can connect analog sensors, digital status inputs, and a serial communications module while keeping the controller footprint small. The 1.8 V to 5.5 V range supports low-voltage systems, while firmware determines sampling strategy, calibration, filtering, and low-power behavior.

LED Lighting Control
The ATTINY88-AU can serve as the control MCU in small LED lighting systems where timer output, PWM-capable functions, and compact integration are useful. Its two flexible timer/counters and 28 I/O lines provide resources for dimming, sequencing, button input, and status indication. The 12 MHz clock and 32-TQFP package support compact control boards, while the 1.8 V to 5.5 V range permits operation across common low-voltage rails.
Direkomendasikan
Battery-Powered Accessory
The ATTINY88-AU is suitable for battery-powered accessories because it offers a low-power CMOS 8-bit platform with sleep-oriented microcontroller architecture and a 1.8 V to 5.5 V operating range. Its 8 KB flash, 512 bytes SRAM, and 64 bytes EEPROM provide local program and data storage for simple control logic. The designer must still verify sleep currents, ADC behavior, clock startup time, and regulator efficiency because those values were not included in the supplied verified data.
Direkomendasikan
Simple Data Acquisition Module
The ATTINY88-AU can be used in a simple data-acquisition module because its 8-channel 10-bit ADC provides analog measurement capability while 32 general-purpose working registers support control and peripheral configuration. I2C and SPI allow connection to sensors, memory, or a host controller. The 32-TQFP package leaves a defined surface-mount footprint, but analog grounding, reference stability, sample timing, and calibration must be handled in the PCB design.

Industrial Control Interface
The ATTINY88-AU can implement a compact industrial control interface for status inputs, alarm outputs, and local sensor conditioning. Its 28 I/O lines and timer resources allow several digital functions to coexist, while the ADC supports process-voltage monitoring. The 1.8 V to 5.5 V supply range is useful for embedded control boards, but industrial suitability should be validated against the required temperature range, isolation, EMC, and regulatory requirements; those details are not supplied here.
Direkomendasikan
Consumer Device Controller
The ATTINY88-AU is appropriate for a small consumer device controller that needs local logic, analog input, and serial peripherals without a high-performance processor. The 8-bit AVR core and 8 KB flash are sized for control-oriented firmware, while I2C and SPI can connect display, sensor, or storage components. The 32-TQFP footprint supports automated assembly, and the 1.8 V to 5.5 V range supports common embedded supply architectures. Enclosure, ESD, standby-current, and user-interface requirements remain application-specific.

Low-Cost Educational Controller
The ATTINY88-AU can support low-cost educational microcontroller projects because it exposes ADC, I2C, SPI, timers, and general-purpose I/O in one small package. Students can use the 8-bit AVR platform to practice firmware, peripheral configuration, sensing, and serial communication without adopting a larger processor. The 32-TQFP package is easy to inspect and route on a moderate-density PCB, although development boards and programming adapters must be selected with the correct device support and pinout.

Catatan Desain
Route the TQFP-32 footprint and all power, ground, programming, and signal pins according to the manufacturer package drawing. Keep the decoupling capacitor path to the supply pins short and place it close to the device. Because the verified data does not include a complete pin-name list, verify every pin assignment and alternate function against the current manufacturer datasheet before fabrication.
For designs using I2C or SPI, preserve the intended signal topology and keep traces short where possible. Provide pull-up resistors for I2C only when required by the bus specification and selected operating voltage. For ADC inputs, use a stable reference and controlled source impedance; the ATTINY88-AU's 8-channel 10-bit ADC is useful for measurement, but conversion accuracy depends on analog layout, sampling timing, and calibration.
Do not substitute a pin-compatible-looking device solely from package dimensions. Confirm device identity, flash size, SRAM, EEPROM, voltage limits, timer resources, ADC behavior, programming interface, and clock requirements. The verified cross-reference material identifies ATtiny48 and ATMEGA88PA as TQFP-32 candidates, but it does not establish that every firmware image or board configuration is functionally interchangeable.
Informasi Konformitas
The supplied verified data confirms In Production status and an active lifecycle, but does not provide specific RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations.
