ATTINY87-XU Visão geral
An 8-bit AVR microcontroller is a compact embedded processor in the hierarchy of microcontrollers, embedded processors, and semiconductor control devices. The AVR architecture uses a RISC instruction set and general-purpose working registers to execute control and communication firmware efficiently. ATTINY87-XU belongs to the ATtiny family and targets designs that need more connectivity than a basic minimal AVR while retaining a small 20-pin surface-mount footprint.
Verified device features include 8 KB of In-System Programmable Flash, 512 B of nonvolatile EEPROM, 512 B of SRAM, 32 8-bit general-purpose working registers, an 8-bit timer/counter with compare modes, and 16 I/O lines. The manufacturer describes 123 powerful instructions, with most completing in a single clock cycle. Its integrated LIN controller supports communication designs where a dedicated network interface would otherwise increase component count.
The ATTINY87 family uses Microchip AVR firmware tools and programming workflows. The verified results identify MPLAB Snap support using a High-Speed USB 2.0 computer interface, an 8-pin single-in-line connector to the target, and two device I/O pins plus the reset line for in-circuit debugging and In-Circuit Serial Programming. This makes firmware programming and debug access practical during prototype bring-up and production programming.
Typical applications include LIN-connected automotive accessories, compact sensor interfaces, actuator controllers, building and industrial control nodes, low-power embedded instruments, and communication modules. In each case, the 16 MHz core, 8 KB program memory, and integrated serial interfaces reduce the need for external digital components.
A key design consideration is selecting the correct package, pin mapping, clock arrangement, programming interface, and operating voltage before laying out a production PCB. Because the supplied excerpts do not include the complete pin table, voltage ranges, electrical limits, ADC details, or LIN timing values, those items must be verified in the official ATTINY87 documentation before release to manufacturing.
This page consolidates manufacturer facts, distributor listings, package information, connectivity details, and application guidance. It also clearly identifies where complete pinout, electrical, pricing, lifecycle, and drop-in replacement data were not available in the verified excerpts, helping engineers separate confirmed specifications from information that still requires datasheet review.

Aplicações típicas
ATTINY87-XU é adequado para 6 aplicaçãos: LIN-Connected Automotive Accessory Controller, Compact Industrial Sensor Interface, Small Actuator and Relay Control, Embedded Communication Module, Low-Power Control Node, Programmable Logic Controller.
LIN-Connected Automotive Accessory Controller
ATTINY87-XU fits a compact LIN node because it combines a 16 MHz 8-bit AVR core with an integrated LIN controller and 16 general-purpose I/O lines. The MCU can execute control logic for an accessory while leaving GPIO available for switches, indicators, interlocks, or actuator drive stages. Its 8 KB ISP Flash and 512 B SRAM provide useful local firmware capacity for protocol handling and debounce logic. The exact LIN transceiver, pin assignment, termination, and electrical limits are not supplied in the verified excerpts and must be confirmed in the complete Microchip documentation before layout release.
Recomendado
Compact Industrial Sensor Interface
The ATTINY87-XU can serve as the local controller for a small industrial or building sensor node, using 16 I/O lines to interface discrete inputs and outputs while firmware performs sampling control, filtering, status reporting, and fault handling. The 16 MHz AVR core provides a compact control platform without an external processor. A serial communication function such as LIN can support a wired network topology. Supply limits, analog-converter details, thresholds, and timing margins were not included in the verified excerpts and must be taken directly from the complete ATTINY87 documentation before implementation.
Recomendado
Small Actuator and Relay Control
ATTINY87-XU is suitable for small actuator and relay-control boards where firmware coordinates input conditions, timing, interlocks, and output states. Its 16 general-purpose I/O lines provide a substantial control surface for a 20-pin TSSOP, while the 8-bit timer/counter with compare modes can support timing-dependent operations. Power switches and relay drivers still require suitable external circuitry because the MCU must not be assumed to drive loads directly. Verify output current, voltage, thermal, isolation, and flyback requirements from official documentation before applying power.
Recomendado
Embedded Communication Module
ATTINY87-XU can act as the protocol-processing element in a compact embedded communication module because its AVR core, 16 MHz operation, 16 I/O lines, and integrated LIN controller provide local computation and bus connectivity. The 8 KB ISP Flash supports protocol and application firmware, while 512 B EEPROM can retain configuration or calibration data. Designers should partition memory carefully and confirm serial timing, peripheral multiplexing, and package pins in the full datasheet. The verified data does not quantify RAM headroom for a particular protocol stack.
Recomendado
Low-Power Control Node
The ATTINY87-XU supports low-power embedded control because Microchip positions the ATTINY87 as a high-performance, low-power 8-bit AVR microcontroller. A compact node can use its timer and GPIO resources for periodic sensing, local actions, and communication updates. Actual battery life depends on operating mode, clock source, sleep configuration, bus activity, and external loads, none of which have verified current figures in the supplied excerpts. Do not size a battery from generic low-power claims; measure or consult the official active and power-down electrical characteristics.
Recomendado
Programmable Logic Controller
ATTINY87-XU can serve as the processor in a compact programmable logic controller or fixed-function control board. Sixteen I/O lines, an 8-bit timer/counter with compare modes, and 8 KB Flash provide the fundamental resources for deterministic input scanning, output sequencing, alarm handling, and local configuration. The design must avoid exceeding pin multiplexing and timing limits, and safety-critical decisions require formal validation beyond ordinary datasheet checks. Because the verified excerpts do not include complete timing or watchdog information, these functions require confirmation in the complete documentation.

Notas de projeto
Reserve the exact ATTINY87-XU 20-TSSOP footprint and route programming access to the device's documented I/O and reset connections. Microchip states that MPLAB Snap can use two target I/O pins and the reset line through an 8-pin SIL connector. Keep this connector accessible on prototype boards and usable in production. Because the supplied excerpts do not contain the complete pin table, do not assign connector signals from memory; verify them against the official package drawing first.
Confirm the device's operating-voltage range, external clock requirements, active current, sleep current, and absolute maximum ratings from the complete ATTINY87 datasheet before selecting a regulator or planning battery life. The verified material calls the MCU low power but provides no numerical current figures. For a LIN node, account separately for the transceiver and any load drivers because their current can dominate the MCU budget. Validate startup, reset, and bus-fault behavior across the complete board voltage range.
Place required support and protection components according to Microchip's complete ATTINY87 layout guidance, especially around supply pins, the LIN interface, clock circuitry, and exposed programming pads. The verified excerpts do not specify capacitor values, LIN transceiver selection, or pin multiplexing, so adding guessed parts could impair timing or bus compliance. Perform signal-integrity and EMC review on the finished node, and keep long bus or high-current paths physically separated from sensitive control signals.
Do not treat similarly named TinyAVR devices as pin-compatible simply because they are 8-bit AVR products or use related packages. The verified comparison pages mention ATTINY861A and other devices, but the supplied excerpts do not establish a complete pin, memory, peripheral, or electrical match. Review the official device documentation for every replacement, then verify reset behavior, ICSP access, timer resources, LIN functions, and supply limits before approving a substitution.
Informações de conformidade
The verified excerpts identify a green industrial-temperature ATTINY87-XU offering and state an operating range of -40C to +85C, but they do not explicitly establish RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status.
