ATTINY4-TS8R - 8-Bit 512B AVR MCU | Microchip
部品番号: ATTINY4-TS8R ✓ 生産中ATTINY4-TS8R 概要
An 8-bit microcontroller is a programmable control device that combines a processor core, nonvolatile program memory, data memory, I/O ports, and embedded peripherals on one integrated circuit. The ATTINY4 belongs to the ATtiny family, a TinyAVR subset of the AVR enhanced RISC architecture. Its compact footprint allows it to fit close to sensors, switches, indicator circuits, and actuators, while the four I/O pins provide direct digital interaction with the surrounding system.
Verified listings identify 512 bytes of flash, 32 bytes of SRAM, four I/O pins, an internal oscillator, and SOT-23-6 packaging. Distributor and comparison data also identify power-on reset, pulse-width modulation, and watchdog timer support. The manufacturer datasheet describes the ATtiny4/5/9/10 family as a low-power CMOS AVR platform whose enhanced RISC architecture executes most instructions in a single clock cycle, providing throughput close to 1 MIPS per MHz. This execution model is useful for small state machines and tightly bounded control loops.
The ATTINY4-TS8R is particularly suitable for simple embedded controllers, sensor interfaces, indicator logic, keyboard or switch scanning, and compact sequencing systems. Its 512-byte program memory limits application complexity, while 32 bytes of SRAM requires careful data allocation and avoidance of unnecessary library overhead. A production design should verify that its reset behavior, oscillator requirements, programming method, and electrical limits fit the intended product.
The -TS8R ordering suffix identifies the supplied SOT-23-6 tape-and-reel configuration, while factory programmability allows device-specific firmware to be preloaded before shipment. Designers should confirm the exact programming and labeling workflow with Microchip, account for programming pins and exposed product programming requirements, and validate the assembled firmware under the target voltage, temperature, and load conditions. MicrochipDirect reports the part as factory programmable and in stock, with an estimated shipment date shown for 15-Oct-2026.
This page combines the verified distributor specifications, manufacturer-oriented datasheet links, package details, sourcing data, and practical design guidance for ATTINY4-TS8R. Because the supplied search data does not expose the complete electrical timing tables, pin-level programming requirements, or verified pricing tiers, those values remain explicitly identified as needed rather than inferred. This page provides an honest basis for initial design review, procurement comparison, and follow-up validation against the manufacturer documentation.

主な用途
ATTINY4-TS8R の用途: 6 件s: Compact Sequencing Controller, Simple Switch and Indicator Interface, Low-Cost Sensor Signal Conditioning, PWM Output and Small Actuator Control, Battery-Powered Embedded Control, Factory-Programmed Custom Peripheral.
Compact Sequencing Controller
ATTINY4-TS8R fits a small sequencing controller where fixed order matters more than general-purpose processing. Its 8-bit AVR core executes most instructions in a single clock cycle, while 512 bytes of flash can hold a tightly bounded state machine and 32 bytes of SRAM can hold a small working state. The device can sequence LEDs, relays, or actuator enable lines through its four I/O pins. Its internal oscillator, power-on reset, and watchdog support help reduce external circuitry, but the very small memory footprint requires concise firmware and disciplined RAM allocation.
おすすめ
Simple Switch and Indicator Interface
The ATTINY4-TS8R is well suited to a small switch and indicator interface because it provides four I/O pins, PWM capability, and an internal oscillator. It can read a limited number of inputs and drive LEDs, logic-level indicators, or a simple display control without requiring an external clock. The SOT-23-6 package helps minimize board area, while power-on reset assists startup behavior. Designers should avoid excessive debounce buffers and large display state tables because the available flash and SRAM are limited.
おすすめ
Low-Cost Sensor Signal Conditioning
ATTINY4-TS8R can provide limited local signal conditioning for a simple sensor node, such as threshold decisions, debouncing, or translating a sensor state into a digital output. Its four I/O pins are suitable for a small sensor interface when the application does not require high-resolution conversion or extensive buffering. The internal oscillator and low-power CMOS family architecture support compact embedded designs. Because the supplied data does not specify analog peripherals or supply-current limits, analog front-end requirements must be verified against the exact datasheet.
おすすめ
PWM Output and Small Actuator Control
The ATTINY4-TS8R can generate PWM-based control signals for small actuators, indicator brightness, or simple timing functions. Its verified peripheral list includes PWM, while the four I/O pins provide a limited but workable interface to external drivers. The part is most appropriate when the control algorithm is short and does not require feedback processing or large command buffers. A MOSFET or other driver stage may be required when the load exceeds the microcontroller output limits, which must be confirmed from the manufacturer documentation.
おすすめ
Battery-Powered Embedded Control
ATTINY4-TS8R can serve as a battery-powered embedded controller when the application is small enough for its 512-byte flash and 32-byte SRAM. The ATtiny4/5/9/10 family is described as low-power CMOS, and the part uses an internal oscillator according to the verified listing, helping reduce external component count. Power consumption still depends on the actual operating mode, supply voltage, I/O loading, and watchdog configuration, none of which are numerically provided here. Validate current consumption against the manufacturer datasheet before estimating battery life.
おすすめ
Factory-Programmed Custom Peripheral
The ATTINY4-TS8R is useful as a factory-programmed custom peripheral when a product needs a dedicated controller embedded in a small assembly. The verified MicrochipDirect listing specifically identifies factory programmability, allowing application-specific behavior to be loaded before shipment when supported by the manufacturing workflow. The SOT-23-6 package supports compact modules, while four I/O pins can expose a defined control or status interface. Production teams should document the firmware revision, programming method, serialization requirements, and traceable device identity before release.

設計ノート
Use the exact SOT-23-6 land pattern and pin-1 orientation from the manufacturer package drawing. Because the supplied data does not include the complete pin table, do not infer pad assignments from a distributor photo or a generic SOT-23 symbol. Place the MCU close to its decoupling and programming-access points, and reserve enough board edge and component clearance for reliable assembly and inspection.
Confirm the device supply-voltage limits, operating current, sleep current, and I/O injection limits in the ATTINY4/5/9/10 family datasheet before selecting the power source. The verified data identifies an internal oscillator and low-power CMOS family, but it does not provide numerical current values. Use the manufacturer’s recommended decoupling arrangement and avoid adding loads to I/O pins until their absolute maximum and DC characteristics are confirmed.
The 512-byte flash and 32-byte SRAM limits are the primary design constraints. Avoid large libraries, recursive routines, broad buffers, and unnecessary abstraction layers that can exhaust code or RAM. Validate the compiled image size and map file, and test all reset, watchdog, and PWM paths at the intended voltage and temperature. Factory programmability also requires a controlled firmware-revision and device-serialization process.
Keep the power ground path short and place input/output connections away from sensitive analog or high-speed nets. If the MCU drives a relay, motor, lamp, or other inductive load, use an appropriate protection and driver stage rather than relying on the four I/O pins directly. Validate timing and ringing with an oscilloscope after layout because the supplied data does not specify board-level EMI or output-drive details.
コンプライアンス情報
Verified search data describes the device as a green SOT-23-6 package, but no formal RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declaration was supplied. Compliance status therefore remains unknown pending manufacturer documentation.
