ATTINY807-MN - 20MHz 8KB 24-VQFN Microcontroller | Microchip
N.º da peça: ATTINY807-MN ✓ AtivoATTINY807-MN Visão geral
An 8-bit microcontroller is a programmable integrated circuit designed to execute embedded control tasks from a compact instruction set. Within the semiconductor hierarchy, the ATTINY807 belongs to the AVR family of tinyAVR devices, combining general-purpose digital control with analog sensing and serial communications in a low-power embedded-processing platform.
The principal headline specifications are a 20 MHz operating speed, 8 KB of Flash program memory, and a 24-VQFN (4x4 mm) package. Its 512-byte SRAM supports working variables and stack operations, while 128 bytes of nonvolatile EEPROM provide dedicated storage. The processor's hardware multiplier accelerates multiplication-intensive control and signal-processing routines without requiring software multiplication loops.
Microchip describes the series as using a flexible, low-power architecture with an Event System, SleepWalking, accurate analog features, and advanced peripherals. Event System routing can connect peripherals directly, reducing CPU intervention in suitable event-driven designs. SleepWalking allows supported peripherals to operate while the CPU sleeps, supporting low-power event handling. The exact peripheral assignments and operating limits should be confirmed in the manufacturer datasheet before design release.
Typical uses include compact industrial controllers, low-power sensor nodes, building automation modules, small motor and actuator controllers, battery-powered instruments, and communication-enabled embedded products. Serial interfaces identified in the verified product data include I2C, SPI, and USART, allowing the MCU to connect sensors, transceivers, displays, and external nonvolatile memory.
Designers should pay particular attention to pin multiplexing, clock configuration, decoupling, programming, and the exposed thermal-pad connection required by the 4x4 mm VQFN footprint. Because the available verified data does not state the supply-voltage range, ADC characteristics, GPIO count, or complete operating-temperature range, those values must be checked against the official ATTINY807 documentation rather than inferred from the family name.
This page consolidates verified manufacturer and distributor information, a same-package replacement candidate, application guidance, and practical design cautions. It deliberately distinguishes documented facts from parameters that still require confirmation, helping engineers evaluate the ATTINY807-MN without treating generic tinyAVR assumptions as part-specific specifications.

Aplicações típicas
ATTINY807-MN é adequado para 6 aplicaçãos: Industrial Sensor and Control Nodes, Battery-Powered Monitoring Devices, Building Automation Modules, Small Motor and Actuator Controllers, Serial Communication Hubs, Low-Power Instrumentation Products.
Industrial Sensor and Control Nodes
The ATTINY807-MN fits compact industrial sensor nodes that need deterministic embedded control without a higher-cost processor platform. Its 8-bit AVR core operates at up to 20 MHz, while 8 KB of Flash provides room for acquisition logic, filtering, diagnostics, and communications firmware. The 512-byte SRAM and 128-byte EEPROM support working state and a small amount of retained configuration data. I2C and SPI permit connection to sensors, converters, and external memory, while SleepWalking and the Event System can support low-power event-driven behavior. Because the verified information does not state the supply range or industrial temperature limits for the exact -MN ordering code, engineers must verify those ratings before deploying the device in factory equipment.
Recomendado
Battery-Powered Monitoring Devices
ATTINY807-MN is appropriate for battery-powered monitoring devices where an 8-bit MCU must collect sensor data and remain responsive without excessive processing overhead. The 20 MHz AVR processor has a hardware multiplier, while 512 bytes of SRAM and 128 bytes of EEPROM provide space for runtime variables and retained settings. SleepWalking may allow supported peripherals to monitor events while the CPU sleeps, reducing the need for continuous polling. I2C and SPI are useful for digital sensors and external nonvolatile storage. Final power-budget calculations require the exact sleep current, active current, wake-up time, and supply-voltage limits from the official ATTINY807 documentation, because these values are not included in the verified search data.
Recomendado
Building Automation Modules
The ATTINY807-MN can serve as the local controller in a compact building-automation module that coordinates sensors, actuators, and serial transceivers. Its 20 MHz speed and hardware multiplier support responsive control logic, while 8 KB of Flash is suitable for communication protocols, state machines, diagnostics, and configurable behavior. The Event System is useful for routing events between peripherals, potentially reducing CPU overhead, and SleepWalking supports low-power operation in intermittently connected nodes. I2C is appropriate for common building sensors, while SPI and USART provide flexible links to transceivers or local displays. Product qualification should confirm the exact analog channels, GPIO mapping, operating-temperature grade, and supply limits before final selection.
Recomendado
Small Motor and Actuator Controllers
ATTINY807-MN is suitable for compact motor or actuator controllers where a fast 8-bit control loop must coexist with serial communications. The 20 MHz AVR core and hardware multiplier provide useful arithmetic capability, while the Event System can connect timed events among supported peripherals. PWM-capable functions can support actuator commands when their channel allocation and timer assignments are verified in the datasheet. The 8 KB Flash capacity is sufficient for embedded state machines and fault handling, while 512 bytes of SRAM handles immediate control variables. Because motor environments introduce switching noise, ground partitioning, decoupling, and protection must be designed carefully; the verified data does not specify internal PWM channels, ADC resolution, or absolute maximum pin ratings.
Recomendado
Serial Communication Hubs
ATTINY807-MN can be used in a protocol-conversion or communication-hub design because the verified product data identifies support for I2C, SPI, and USART. The 20 MHz AVR core can coordinate multiple serial endpoints, handle framing, and implement device-specific protocol logic. Its 8 KB Flash stores firmware, 512 bytes of SRAM supports active buffers, and 128 bytes of EEPROM preserves small configuration blocks. The Event System may reduce processor involvement by routing events among compatible peripherals, although exact event-routing capabilities must be checked against the device documentation. Designers should use this part where a small, deterministic embedded controller is sufficient rather than assuming it can replace a higher-pin-count or higher-memory microcontroller.
Recomendado
Low-Power Instrumentation Products
ATTINY807-MN fits low-power instrumentation that combines local signal conditioning, configuration storage, and a serial reporting function. The 20 MHz processor provides fast control-loop execution, and its hardware multiplier assists common arithmetic operations without requiring a 16- or 32-bit processor. Flash accommodates calibration and communication firmware, SRAM supports transient measurement data, and EEPROM retains settings across power cycles. I2C and SPI allow attachment of precision sensors or external memory, while SleepWalking can support responsive operation with reduced CPU activity. Instrumentation designs still need to verify ADC resolution, analog input ranges, reference accuracy, and noise specifications; the available verified results describe accurate analog features qualitatively but provide no quantitative ADC data.

Notas de projeto
Treat the 24-VQFN (4x4 mm) footprint as a compact but assembly-sensitive design. Place input and internal supply decoupling directly at the relevant device pins, maintain the manufacturer's recommended land pattern and exposed-pad connection, and use an assembly stencil appropriate for the 0.4 mm pitch geometry. The verified data confirms the package dimensions and pin count but does not provide the recommended PCB layout, so the current Microchip package drawing and application guidance must control the layout.
Budget the power path from both accuracy and implementation perspectives. The 8 KB Flash and 512-byte SRAM support compact firmware, but the exact operating current and supply limits are not present in the verified material. Before selecting the ATTINY807-MN, confirm its operating-voltage range, maximum clock conditions, and power-consumption modes from the datasheet. The exposed thermal pad is an electrical and thermal connection, so it should be connected according to the manufacturer's guidance rather than treated only as a mechanical feature.
Preserve signal integrity by separating analog, digital, clock, and serial routes as the selected peripheral assignments require. Keep I2C and SPI traces short where their buses operate at high speed, provide the required pull-up arrangements for I2C, and account for return paths beneath high-speed or switching nodes. Because no complete pinout or analog-channel specification was included in the verified data, finalize these details only after assigning functions to the 24 device pins from the official datasheet.
Do not treat ATTINY807, ATTINY807-MN, ATTINY807-MNR, and ATTINY807-MFR as identical ordering codes. The verified comparison identifies temperature and packaging distinctions among these variants. Confirm the manufacturer ordering table, programmed-device compatibility, exposed-pad requirements, and temperature grade before substituting one order code for another. Also avoid using generic ATtiny pinouts: peripheral multiplexing and alternate-function assignments must be verified for this specific 24-pin device.
Informações de conformidade
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not_applicable because no automotive qualification was identified; it should not be interpreted as an automotive endorsement.
