Артикул: ATTINY417-MN ✓ АктивенATTINY417-MN Обзор
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. The ATTINY417 belongs to the TinyAVR family, which sits within the broader hierarchy of 8-bit AVR microcontrollers, embedded controllers, and semiconductor components. This combination makes the device useful for small control systems that need programmable logic, serial communication, analog measurement, and compact board area without a larger application processor.
The ATTINY417's headline features include its 20 MHz operating speed, 4 KB Flash memory, 256 B SRAM, and 128 B EEPROM. The processor includes a hardware multiplier, while the device uses Microchip's Core Independent Peripherals architecture. Its 24-QFN 4 x 4 mm package is intended for space-constrained surface-mount assemblies where a compact land pattern is important.
The 4.5 V to 5.5 V operating-supply range makes the ATTINY417 suitable for 5 V embedded systems. The manufacturer lists the ATTINY417-MN as an industrial-temperature variant with an indicated maximum rating of 105°C. The part identifier appears in a 24-QFN 4 x 4 mm package configuration and is associated with Functional Safety microcontroller terminology in distributor technical listings.
Typical applications include compact industrial controllers, building and access-control modules, sensor-hub boards, communication equipment, LED-control systems, and compact consumer appliances. In each case, the MCU can execute firmware close to the sensed or controlled mechanism, reducing system complexity and keeping the design within a small, low-power embedded platform.
Designers should assign every power pin and signal connection from the package pin-description table, preserve the recommended decoupling arrangement, and confirm operating voltage, clock configuration, and peripheral assignments in the manufacturer datasheet. PCB planning must accommodate the 24-QFN 4 x 4 mm footprint, exposed thermal pad requirements, and the selected programming and debugging interface.
This product record combines the manufacturer specifications, exact package identification, sourcing context, engineering-use guidance, and selection criteria for ATTINY417-MN. It is intended to help engineers evaluate the device quickly while retaining the datasheet as the controlling reference for electrical limits, pin definitions, programming, and qualification requirements.

Compact Industrial Control Modules
The ATTINY417-MN fits compact industrial-control modules that coordinate discrete inputs, outputs, and simple sequencing functions. Its 20 MHz AVR processor provides useful operating headroom for responsive control firmware, while 4 KB of Flash, 256 B of SRAM, and 128 B of EEPROM support configuration storage and working state. The 4.5 V to 5.5 V supply range aligns with common 5 V control architectures, and the 24-QFN 4 x 4 mm package reduces board footprint. Designers should implement the datasheet power, decoupling, reset, and programming requirements, then verify the assembly against the indicated 105 °C industrial-temperature rating.

Sensor and Condition Monitoring
The ATTINY417-MN is appropriate for local sensing and condition-monitoring nodes that must collect measurements, apply thresholds, and communicate status through embedded peripherals. The 20 MHz AVR core supports timely peripheral servicing, while the 4 KB Flash capacity accommodates self-contained control and logging code. Its 128 B EEPROM is useful for retaining small configuration or calibration values, and 256 B of SRAM supports temporary measurement and protocol processing. The 24-QFN 4 x 4 mm package helps maintain a small board footprint. A production design should select external sensors with compatible electrical interfaces and follow the manufacturer pin, clock, decoupling, and exposed-pad guidance.

Access and Security Control
The ATTINY417-MN can serve as the controller in compact access-control, credential-reader, and security-module products where deterministic embedded logic is required in a small package. Its 20 MHz processor handles polling and protocol routines, and the 4 KB Flash, 256 B SRAM, and 128 B EEPROM provide adequate storage for small control applications. The 4.5 V to 5.5 V operating range supports conventional 5 V system rails, while the 24-QFN 4 x 4 mm package simplifies dense board construction. Engineers should pay particular attention to secure programming practices, external authentication components, ESD protection, and the complete manufacturer pin and power recommendations.

Communication Equipment
The ATTINY417-MN is well suited to small communication appliances, protocol converters, and interface modules built around serial links. The 20 MHz AVR core can service interrupt-driven communication tasks, while 4 KB of Flash accommodates compact protocol stacks and 256 B of SRAM supports packet buffers. The device's 128 B EEPROM can retain limited configuration information, and its compact 24-QFN 4 x 4 mm package assists space-constrained implementations. The 4.5 V to 5.5 V supply range fits 5 V interface electronics. Firmware and hardware reviews should confirm baud-rate tolerance, interrupt latency, connector protection, reference-clock requirements, and power decoupling.

LED Lighting Control
The ATTINY417-MN can control compact LED lighting systems that require sequencing, dimming decisions, status indication, or configurable drive behavior. Its 20 MHz AVR core and 256 B of SRAM support time-sensitive control routines, while 4 KB of Flash holds application firmware and 128 B of EEPROM can preserve simple operating profiles. The 4.5 V to 5.5 V operating range suits 5 V logic sections, and the 24-QFN 4 x 4 mm package leaves room for driver components in compact fixtures. The design must translate controller outputs through suitable driver circuitry, account for LED startup and thermal behavior, and follow the datasheet's I/O, grounding, and decoupling requirements.

Заметки по проектированию
Use the 24-QFN 4 x 4 mm package drawing in Microchip datasheet DS40001901C as the authority for land geometry, pin-one orientation, and exposed-pad connection. Place the input and output bypass capacitors adjacent to their respective supply pins, provide a low-impedance ground return beneath and around the device, and avoid routing fast or sensitive signals through the exposed-pad region. The compact package leaves little tolerance for assembly drift, so verify the land pattern against the current manufacturer package drawing before fabrication.
Separate clocks, programming signals, and communication interfaces from noisy power-conversion stages where the board architecture permits. Keep traces short, maintain a continuous ground reference, and place storage or communication components so their switching current does not share narrow return paths with the ATTINY417-MN. Because the MCU operates from 4.5 V to 5.5 V, verify every connected peripheral for 5 V compatibility and ensure transient-producing loads are not coupled directly into sensitive signal paths.
Do not treat the ATtiny417 family summaries as permission to mix package pinouts. The ATTINY417-MN is identified in a 24-QFN 4 x 4 mm package, and its exact pin assignments, exposed-pad requirements, programming connections, and peripheral alternatives must come from the manufacturer datasheet. Also confirm clock source, reset configuration, operating mode, and supply sequencing in firmware documentation. A footprint that appears physically similar can still be unusable if its numbering or exposed-pad treatment differs.
Информация о соответствии
The ATTINY417-MN is identified as a green industrial-temperature product, but no explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declaration was identified.
