ATTINY88-PU - 8-Bit 12MHz AVR MCU | Microchip Technology
MPN： ATTINY88-PU ✓ 啟用中ATTINY88-PU 概覽
A microcontroller is a semiconductor that integrates a processor core, nonvolatile program memory, data memory, and peripherals into one device. The ATtiny88 belongs to the 8-bit AVR family, a low-complexity controller family suited to real-time control loops, digital I/O, timers, communication interfaces, and small sensor systems. The ATTINY88-PU uses an advanced RISC architecture and is supported by an ecosystem of AVR-compatible tools and libraries.
The verified feature set includes 8KB of in-system programmable flash, 64 bytes of EEPROM, 512 bytes of SRAM, 123 powerful instructions, and a 12MHz operating speed. Its 1.8V to 5.5V range supports both low-voltage and conventional 5V designs. The 28-PDIP package is useful for prototypes, through-hole assembly, hand wiring, and designs where a socket or easy rework is useful.
Typical embedded uses include environmental monitoring, small motor or relay control, LED status systems, keypad interfaces, and compact control boards. Because the exact pin names, timers, peripherals, electrical limits, and package drawing are not supplied in the verified data, those details should be confirmed in the manufacturer datasheet before schematic capture or firmware deployment.
Design with the DIP footprint, clock source, programming interface, decoupling requirements, and I/O voltage limits verified against the official datasheet. The 12 MHz operating speed does not by itself guarantee a particular timer frequency; the actual peripheral clock behavior depends on the selected clock source, fuse configuration, and divider settings.
This page combines verified manufacturer and distributor facts with purchasing context, application guidance, and conservative replacement qualification. It does not claim a drop-in alternative unless the same package and pin-level compatibility are explicitly supported by available cross-reference data.

典型應用
ATTINY88-PU 適用於 6 應用s: Environmental Sensor Node, LED Status and Indicator Control, Small Relay and Actuator Control, Remote Industrial Sensor Interface, Battery-Powered Control Module, Programmable Logic and Embedded Control.
Environmental Sensor Node
The ATTINY88-PU fits a compact sensor node that needs local control rather than a high-performance operating system. Its 8KB in-system programmable flash can hold acquisition logic, calibration constants, and communication routines, while 512 bytes of SRAM provides a defined working-memory budget for temporary measurements and protocol state. The verified 1.8V to 5.5V range supports low-voltage sensor platforms and conventional 5V installations. Because the supplied data does not specify ADC channels, timer resources, or exact I/O assignments, the designer should verify those functions in the manufacturer datasheet before selecting the sensor interface.
推薦
LED Status and Indicator Control
ATTINY88-PU is suitable for an LED status controller because its 8-bit AVR core can execute sequencing, blinking, fault indication, and button-management logic without a larger embedded platform. The 12MHz maximum clock provides a convenient processing target for straightforward digital control, and the 1.8V to 5.5V supply range allows integration with common low-voltage indicator circuits. Use current-limiting resistors and verify the available I/O drive and port-mapping limits in the official datasheet. The 512-byte SRAM budget should be respected if the design also uses displays or buffering.
推薦
Small Relay and Actuator Control
The ATTINY88-PU can implement a compact relay, solenoid, or actuator controller when the selected output driver meets the load’s voltage and current requirements. Its 8KB flash is useful for debounce logic, state machines, timing, and safety interlocks, while the 12MHz AVR core supports responsive digital control. The MCU should not directly drive a high-energy load unless the datasheet explicitly permits the required output current; an external transistor, MOSFET, or driver is generally the correct interface. Exact timer and I/O functions must be confirmed for the selected device variant.
推薦
Remote Industrial Sensor Interface
ATTINY88-PU can serve as a remote sensing endpoint where a compact 8-bit controller, low supply-voltage support, and in-system programmability are useful. It can acquire digital sensor signals, apply thresholds, and transmit status over a suitable communications interface when the selected peripheral assignments support the design. The 28-PDIP package is particularly convenient for prototypes, through-hole construction, and serviceable assemblies. Industrial deployment still requires attention to isolation, surge protection, grounding, and environmental ratings; the verified data does not establish an industrial certification or transient rating.
推薦
Battery-Powered Control Module
ATTINY88-PU is a reasonable starting point for a small battery-powered control module because the verified supply range begins at 1.8V and the device includes an 8-bit AVR core with 8KB of flash. A low-power design can use the controller for intermittent measurement, state retention in EEPROM, and duty-cycled communications. The supplied data does not include sleep-mode current, active current, or battery-life calculations, so those values must be taken from the manufacturer datasheet before making an energy-budget claim. External regulator and load-switch design will also determine the final battery life.
推薦
Programmable Logic and Embedded Control
ATTINY88-PU can combine software control with programmable-logic behavior in a compact industrial or hobby controller. Its 123-instruction AVR architecture and 8KB of programmable flash support firmware for state machines, timing, diagnostics, and communication, while the 28-PDIP package simplifies through-hole prototyping. If the design includes fixed Boolean logic, an external CPLD such as ATF22V10C-10PU may offload deterministic functions and reduce firmware complexity. The exact interface, voltage, and timing assumptions must be verified in the datasheets for both devices.

主要差異化特點
- Production status confirmed by manufacturer listing (對比ATTINY88-AU)
- 28-PDIP through-hole package (對比ATtiny88-MU)
- Verified 1.8V to 5.5V operating range (對比ATMEGA88PV-10PU)
- Defined memory resources for compact embedded designs (對比ATMEGA48V-10PU)
設計說明
Use the verified 28-PDIP footprint as the mechanical starting point and place the programming interface where the assembly and rework process can access it. Confirm pin numbering, orientation, and decoupling requirements from the official Microchip datasheet before routing power or signal traces. Because the supplied data does not include the complete pinout or recommended land pattern, do not freeze the PCB solely from the package name.
Design the supply for the verified 1.8V to 5.5V operating range and include local decoupling appropriate to the selected operating frequency and peripherals. Check the datasheet for absolute maximum voltage, supply current, I/O injection limits, and startup requirements before connecting sensors or actuator-driver circuits. The controller should not be assumed to regulate its own supply or to tolerate arbitrary voltage levels on its pins.
Keep sensitive sensor and timing paths short, provide a defined return path, and separate fast switching or relay-driver currents from analog and digital input routing. The verified data specifies a 12MHz maximum clock but does not provide a complete peripheral or pinout map, so first identify the actual port and timer assignments from the official datasheet. Then validate timing and signal levels in hardware rather than relying only on nominal clock frequency.
Do not treat ATTINY88-AU or ATtiny88-MU as direct replacements for ATTINY88-PU. The supplied comparisons identify different packages and mounting styles, so substituting them requires a board redesign or adapter. Likewise, the presence of an ATtiny88 family comparison page does not prove that every listed MCU is pin-to-pin compatible. Verify package, pin names, memory, voltage, clock, peripherals, and programming requirements before approving a replacement.
合規資訊
The verified search data confirms manufacturer, lifecycle status, package, electrical basics, memory, and distributor listings, but it does not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than inferred.
