ATTINY806-MN - 20MHz 8KB AVR MCU | Microchip Technology
部品番号: ATTINY806-MN ✓ 生産中ATTINY806-MN 概要
An 8-bit microcontroller is a compact embedded-processing IC that combines a processor core, nonvolatile program memory, data memory, and peripherals on one semiconductor device. The ATTINY806 belongs to the hierarchy of 8-bit MCU, embedded microcontroller, AVR microcontroller, tinyAVR microcontroller, and semiconductor. Its compact package and integrated memory make it suitable for compact control, sensing, and communication-adjacent products.
The ATTINY806 uses an AVR processor with a hardware multiplier and can operate at up to 20 MHz. Its 8 KB Flash memory provides nonvolatile program storage, while 512 bytes of SRAM handles working data and 128 bytes of EEPROM preserves values when power is removed. The listed 10-bit ADC and -40°C to +105°C industrial temperature range broaden its usefulness for embedded measurement and control systems.
The device also provides an Event System, SleepWalking, and advanced peripherals according to the Microchip product page. Event System hardware can link peripherals so that an action or routed event can trigger another peripheral without continuous CPU intervention. SleepWalking supports low-power operation by allowing selected events to wake the system, helping balance responsiveness against standby consumption.
Typical applications include compact industrial controllers, low-speed communication modules, sensor-conditioning equipment, building-control interfaces, and small consumer products. Its 20-pin VQFN package supports space-constrained PCB layouts, while the 3 x 3 mm footprint permits a high component density. The -40°C to +105°C rating makes it appropriate for industrial environments when the complete board and peripherals meet their own environmental requirements.
Designers should review the manufacturer pinout, decoupling requirements, clock options, and analog-reference connections before layout. The exposed-pad and thermal behavior of the VQFN package require careful PCB land-pattern and copper placement. Firmware development also depends on the selected AVR toolchain, device configuration settings, and the exact peripheral assignments documented for the ordering code.
This page consolidates manufacturer specifications, distributor availability, lifecycle information, and practical selection considerations for ATTINY806-MN. It also identifies where package-compatible alternatives are not sufficiently documented to claim a safe drop-in replacement, avoiding unsupported cross-brand substitutions.

Industrial Sensor Conditioning
The ATTINY806-MN fits compact industrial sensor-conditioning modules because it combines a 10-bit ADC with an 8-bit AVR processor and operates across -40°C to +105°C. According to the Microchip ATtiny806 product page, the device includes a hardware multiplier, Event System, and SleepWalking, allowing sampled data to be processed and peripherals to be coordinated without continuous CPU polling. The 20-pin VQFN also supports dense control boards. Designers should still verify the exact ADC reference, input range, acquisition timing, and sensor drive requirements against the manufacturer datasheet before finalizing analog circuitry.
おすすめ
Low-Power Monitoring Node
ATTINY806-MN is appropriate for a low-power monitoring node because its SleepWalking capability can respond to peripheral events while reducing the need for continuous CPU activity. Its 512 bytes of SRAM and 128 bytes of EEPROM provide space for working variables and persistent counters, while the 8 KB Flash supports a compact embedded application. The 3 x 3 mm 20-pin VQFN minimizes board area. A practical design should define which events may wake the device, validate sleep-state current on the finished board, and confirm that the watchdog and clock settings satisfy the monitoring duty cycle.
おすすめ
Compact Building-Control Interface
The ATTINY806-MN suits compact building-control interfaces that must consolidate sensing, local logic, and communications into a small board. Its 8-bit AVR core can manage digital I/O and control routines, while the Event System provides a hardware-assisted path for routing events among peripherals. The industrial temperature range of -40°C to +105°C supports equipment deployed across controlled building environments. The 20-pin VQFN conserves board area, but designers must confirm available I/O, communication-interface requirements, power-supply tolerances, and any isolation or regulatory needs before selecting it for the final installation.
おすすめ
Small Communication Controller
ATTINY806-MN can serve as the local controller in a small communication device when the design requires deterministic peripheral coordination rather than a larger application processor. According to Microchip, the Event System can connect peripheral events and reduce the processing burden associated with direct polling, while the hardware multiplier supports compact arithmetic routines. The 8 KB Flash, 512-byte SRAM, and 128-byte EEPROM are sufficient only when the protocol stack and application remain tightly scoped. Engineers should verify UART, SPI, or I²C availability, timing tolerance, buffer requirements, and the firmware footprint before committing to this 20-pin VQFN implementation.
おすすめ
Portable Consumer Accessory
ATTINY806-MN is suitable for a compact portable accessory that needs local control, sensing, and event handling without a large mixed-signal package. Its 3 x 3 mm VQFN leaves board area for the power circuit, sensor, and user interface, while SleepWalking can support low-latency response from selected events. The 10-bit ADC may provide basic level, battery, or analog-sensor measurement, but its accuracy must be assessed against the actual reference and signal path. Before layout, verify battery voltage limits, sleep current, analog noise behavior, exposed-pad treatment, and whether the accessory requires automotive or consumer-specific qualification.
おすすめ
Event-Driven Automation Control
The ATTINY806-MN works well in event-driven automation control where inputs, timers, and outputs must respond predictably within a compact controller. Microchip identifies the Event System as a core family feature, enabling peripheral-to-peripheral event routing that can reduce latency and CPU involvement. The 20 MHz AVR core adds capacity for local logic, and the 20-pin VQFN allows integration beside relays, sensors, or communication transceivers. Practical implementations should test worst-case event latency, debounce behavior, watchdog recovery, and output-driver limits. The datasheet must be consulted for the exact peripheral event sources and I/O assignment supported by this ordering code.

主な差別化要因

- Industrial temperature capability in a compact VQFN （vs ATTINY806-MNR)
設計ノート
Use the exact Microchip 20-pin VQFN land pattern and verify the exposed-pad connection before routing the PCB. The verified source confirms a 3 x 3 mm VQFN but does not provide the land-pattern dimensions, exposed-pad net, or recommended via arrangement. Place local input and output decoupling at the associated supply pins, route sensitive analog signals away from switching nodes, and follow the manufacturer's reference layout rather than relying on a generic QFN footprint.
Do not assume that a 20 MHz clock rating determines the acceptable supply range. The verified data does not provide the ATTINY806-MN operating-voltage limits, so the selected regulator, decoupling network, and brownout behavior must be checked against the manufacturer datasheet. Validate the rail during maximum processor activity, peripheral use, and analog conversion so that voltage margin and transient response remain acceptable.
Avoid treating a similarly named ATTINY1606, ATTINY807, or ATTINY816 device as automatically interchangeable. Package count, memory capacity, event routing, peripheral placement, and pin multiplexing can differ even within one tinyAVR family. Confirm the exact ordering code against Microchip's device comparison and pin documentation, then recompile and retest firmware rather than assuming source-level or board-level drop-in compatibility.
Plan clock, programming, reset, and analog inputs as potentially sensitive nets even though this is an 8-bit MCU. Keep the clock path short, provide the documented programming interface, and avoid routing switching-node currents beneath the MCU or analog ground paths. If the board uses Event System or SleepWalking, measure wake latency and peripheral timing in the assembled design because pad loading, trace length, and decoupling can affect real behavior.
