ATTINY806-MF 16MHz 8KB Flash MCU | Microchip Technology
料号： ATTINY806-MF ✓ 量产中ATTINY806-MF 概述
A microcontroller is a programmable semiconductor that integrates a CPU core, program memory, data memory, and peripherals on one package. The tinyAVR 0-series forms Microchip's low-power, low-pin-count microcontroller family. Its compact footprint and mixed-signal resources make the ATTINY806-MF suitable for local control, sensing, communication, and actuator functions where a larger processor or external discrete implementation would add unnecessary complexity.
The ATTINY806 family combines up to 20 MHz operation, 8 KB Flash, 512 bytes of SRAM, and 128 bytes of EEPROM with an Event System, SleepWalking capability, and accurate analog features. The ATTINY806-MF ordering code is listed at 16 MHz in a 20-VQFN package, with an industrial temperature indication of 125 degrees C and tray packaging. Exact peripheral assignments, electrical limits, and pin functions should be confirmed in the Microchip device documentation before layout release.
The integrated hardware multiplier supports efficient multiplication operations in compact control firmware. The Event System provides a hardware mechanism for routing and synchronizing peripheral events, while SleepWalking allows supported peripherals to operate while the CPU core sleeps. These features can reduce interrupt overhead and improve responsiveness in event-driven sensor and control systems without relying entirely on busy-wait software loops.
Typical uses include compact industrial controllers, low-power sensor nodes, building equipment, appliance controls, and small motor-control subsystems. The 20-pin VQFN format supports space-constrained boards, but its fine pitch requires careful escape routing, solder-paste control, and inspection. For prototypes, the tray package also allows individual components to be handled more conveniently than tape-and-reel production packaging.
Choose the ATTINY806-MF when the design needs an 8-bit AVR core, 8 KB Flash, a 16 MHz rated device variant, and a compact 20-VQFN footprint. Verify the exact pin map, power requirements, peripheral availability, and programming configuration in the manufacturer datasheet.

典型应用
ATTINY806-MF 适用于 6 应用s: Compact Industrial Sensor Node, Building Equipment Control, Appliance Control Module, Small Motor and Actuator Control, IoT Device Endpoint, Functional-Safety-Oriented Control.
Compact Industrial Sensor Node
The ATTINY806-MF fits a compact industrial sensor node that samples an analog quantity, applies calibration or filtering, and reports results through an available serial interface. Its 8-bit AVR processor and hardware multiplier support straightforward control arithmetic, while 512 bytes of SRAM and 128 bytes of EEPROM provide working and parameter storage for a small embedded design. The 20-VQFN 3 x 3 mm package reduces board area in densely populated equipment. Microchip's accurate analog features and SleepWalking capability are useful when the design must monitor inputs without keeping the CPU continuously active. Actual battery or bus power depends on the chosen regulator, sensor duty cycle, and sleep configuration.
推荐
Building Equipment Control
ATTINY806-MF is appropriate for localized building-equipment controls that coordinate inputs, timers, indicator outputs, and communications within a small controller. Its 8 KB Flash capacity is intended for compact firmware, and the hardware multiplier supports common scaling and filtering calculations without requiring a higher-cost MCU. The 20-VQFN package helps reduce the controller footprint where panel or enclosure space is limited. Microchip's Event System can assist with deterministic peripheral sequencing, while SleepWalking can reduce processor activity during idle intervals. The exact pin mux, communication channels, and timing behavior must be reviewed against the design before production release.
推荐
Appliance Control Module
The ATTINY806-MF can serve as the local controller in an appliance module that interprets switches or sensors, drives indicators, and maintains operating state across power cycles. Its 128 bytes of EEPROM can retain small configuration values, while 8 KB of Flash supports a focused control application rather than a large user interface. The 16 MHz ATTINY806-MF ordering code provides practical timing headroom for peripheral coordination. The 20-VQFN 3 x 3 mm package also supports compact, high-density appliance electronics. Firmware should include brownout recovery, invalid-state handling, and communication error recovery appropriate to the appliance's safety and service requirements.
推荐
Small Motor and Actuator Control
ATTINY806-MF can coordinate a small actuator or motor-control subsystem when its timers, I/O, and internal peripherals satisfy the required commutation or sequencing strategy. The 8-bit AVR core is well suited to deterministic command handling, and the hardware multiplier assists with scaling or speed calculations. Its 20-VQFN footprint helps reduce the controller area beside power switching and driver circuitry. In such designs, keep switching-node currents and transients away from sensitive analog and clock paths, and follow the datasheet's grounding and decoupling guidance. This application requires careful validation of timer channels, pin assignments, stall conditions, and thermal behavior before production use.
推荐
IoT Device Endpoint
ATTINY806-MF can act as the low-power endpoint controller beneath a communications module in an IoT device. It can read sensors, validate local inputs, format commands, and manage indicator or actuator outputs while leaving network traffic handling to a companion device. The 8 KB Flash footprint and 512 bytes of SRAM target compact embedded logic, while SleepWalking may reduce CPU activity between peripheral events. The 20-VQFN package minimizes board space in wearable or embedded modules. For a complete wireless design, verify protocol timing, radio-control signals, supply sequencing, and antenna clearance against the companion module's requirements; the MCU does not itself provide a wireless radio.
推荐
Functional-Safety-Oriented Control
ATTINY806-MF is suitable for design exploration involving the ATtiny806 family's functional-safety capabilities, including local monitoring and controlled peripheral behavior in a compact 20-VQFN package. The 8-bit AVR processor, hardware multiplier, Event System, and SleepWalking architecture support deterministic embedded-control tasks where responsiveness and power state matter. A safety-related design must go beyond part selection: engineers should review the applicable Microchip safety documentation, diagnostic coverage, failure modes, watchdog strategy, and the required system-level safety goal. The device should only be released for a safety function after formal hardware and software verification against the applicable application requirements.

选型指南
关键差异点
- Compact 20-VQFN implementation （对比 ATTINY806-SFR)
- Specific 16 MHz ordering option （对比 ATtiny806 family maximum)
- Integrated event-driven control resources （对比 ATTINY48-AUR)
设计说明
Use the manufacturer land pattern for the 20-VQFN 3 x 3 mm package, including its exposed-pad and thermal-via requirements. The fine-pitch footprint has little tolerance for hand rework, so confirm paste volume, stencil aperture design, reflow profile, and AOI coverage during prototype assembly. Preserve the package pin-1 orientation and route sensitive inputs away from switching or high-current output nodes.
Place the required bypass capacitors close to the supply and ground pins using the shortest practical return path. Follow the Microchip device documentation for the capacitor value, voltage rating, and operating range; these values are not established by the product listing. For battery-powered designs, account for regulator quiescent current and wake-up behavior as well as load current when calculating energy use. Validate brownout recovery and state retention across power loss.
Assign analog, communication, timing, and control functions from the official pin table before laying out the board. Route clocks and sensitive analog inputs away from fast-edge signals and noisy switching nodes, and use a continuous ground reference where practical. Because the package is compact, do not infer unused pins or alternate functions from a generic 20-pin symbol; check every assignment against the Microchip documentation for ATTINY806-MF.
Do not treat the ATtiny806 family's stated 20 MHz capability as the rated maximum for every ordering code. The ATTINY806-MF listing identifies 16 MHz, so clock configuration, fuse settings, startup timing, and communication baud-rate assumptions should match that value. Also avoid assuming that ATTINY806-SFR or another package suffix is a drop-in alternative, because package changes require land-pattern and pin-function verification.
合规信息
The product listing identifies ATTINY806-MF as green, but it does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals compliance. Functional-safety characteristics are indicated in the product description; specific safety certification claims should be verified in the manufacturer documentation.
