ATTINY167-AXD - 8-bit AVR MCU, 16KB Flash, 20MHz, TSSOP-20 | Microchip

The Microchip (formerly Atmel) ATTINY167-AXD is an 8-bit AVR RISC-based microcontroller featuring 16KB In-System Programmable Flash, 512B EEPROM, and 512B SRAM, clocked up to 20 MHz, housed in a 20-pin TSSOP package. The device integrates a hardware LIN/UART controller, full-speed USB 2.0 device interface, 16 general-purpose I/O lines, 32 working registers, and a 10-bit ADC, delivering automotive-grade connectivity for embedded LIN nodes and USB peripherals. An 8-bit microcontroller (MCU) is a compact processor that integrates a CPU core, non-volatile program memory, volatile data memory, and peripheral interfaces on a single silicon die. The AVR family uses a modified Harvard architecture with single-cycle instruction execution, making 8-bit MCUs well suited for deterministic, low-power, real-time control tasks. Within the broader semiconductor taxonomy, MCUs belong to the embedded processor category, with 8-bit parts occupying the low-power, cost-sensitive end versus 16-bit and 32-bit MCUs that target higher computational throughput. The ATTINY167-AXD specifically adds automotive bus (LIN) and USB connectivity, a combination rarely found in 8-bit parts, while remaining in a small TSSOP-20 footprint. Key features include 16KB flash (8K x 16 words), 512B EEPROM for non-volatile data, 512B SRAM, hardware LIN 2.0 controller, USB 2.0 full-speed device, 10-bit ADC with up to 11 channels, 8-bit and 16-bit timers with PWM, an enhanced universal serial interface (USI), and a programmable watchdog timer with separate on-chip oscillator. The MCU operates from 1.8V to 5.5V across -40C to +125C (automotive grade), and supports in-system programming via SPI or USB, enabling field firmware upgrades without desoldering. The device uses Microchip's enhanced AVR RISC core executing instructions in a single clock cycle, achieving up to 20 MIPS throughput at 20 MHz. Hardware LIN handling offloads bit timing and checksum generation from the CPU, freeing cycles for application logic. The integrated USB transceiver and dedicated 3.3V regulator simplify USB device designs by eliminating external PHY or LDO components. The TSSOP-20 package balances IO count with a 6.5mm x 4.4mm board footprint, smaller than the SOIC-20 alternative. Typical applications include automotive LIN slave nodes (body controllers, seat modules, mirror controllers, sensor clusters), USB human-interface devices (HID mice, keyboards, custom peripherals), industrial sensor transmitters, and low-cost consumer devices requiring automotive temperature tolerance. The wide operating voltage and temperature range also make it suitable for harsh-environment IoT edge nodes. When designing with this device, prioritize decoupling: place a 100nF ceramic capacitor on each VCC pin within 2mm of the pad, and add a 10uF bulk capacitor near the USB VBUS line. For LIN applications, route the LIN line as a differential pair with the bus pull-up, and add TVS protection such as the NUP2105L. Always configure the fuses for the intended clock source (internal 8 MHz RC vs external crystal) before USB enumeration. This page synthesizes distributor pricing, drop-in compatible alternatives within the TSSOP-20 footprint, and practical automotive design notes not collected on a single manufacturer datasheet page.

The device provides 16 general-purpose I/O lines and combines a compact embedded-control footprint with 16 KB of program memory for firmware, configuration data, and application logic. An 8-bit microcontroller is a compact digital controller built around a processor, nonvolatile program memory, data memory, and configurable input/output peripherals. The ATtiny family belongs to the TinyAVR segment of the AVR product hierarchy. These devices are commonly used where a control system needs deterministic embedded processing but does not require the memory, operating speed, or peripheral complexity of a high-end application processor. The ATTINY167-MU provides 16 KB of ISP Flash, 512 bytes of EEPROM, and 512 bytes of SRAM for persistent configuration and working data. Its 16 general-purpose I/O lines support digital sensing and control, while its 32 general-purpose working registers support efficient execution of the AVR instruction set. The microcontroller also includes an 8-bit timer/counter with compare modes and an 8-bit high-speed timer/counter for periodic and timing-related functions. Its AVR RISC architecture executes most instructions within a single clock cycle, which provides predictable behavior for motor, control, and interface tasks. The 16 MHz operating speed gives designers additional timing headroom over slower 8-bit implementations. The 32-pin VQFN package also includes an exposed pad according to the verified product listings, improving available heat-spreading area on the PCB when the device operates at elevated ambient temperatures or sustained computational load. Typical applications include compact industrial controllers, sensor-conditioning systems, actuator controllers, LED sequencing, low-cost instrumentation, and embedded control modules. The 16 I/O lines make the part useful for products that need several digital inputs and outputs while retaining a small 5x5 mm footprint. Its 16 KB Flash capacity is also appropriate for moderate control firmware that must be programmed in-system through the AVR ISP interface. The primary design consideration is matching firmware requirements to only 512 bytes of SRAM and 16 KB of Flash. Avoid interrupt handlers or library structures that require excessive stack space, and verify bootloader, application, and in-system programming requirements before final firmware allocation. PCB layouts must also follow the manufacturer's exposed-pad and thermal-land guidance rather than treating the VQFN as a conventional leaded package. This page combines verified manufacturer and distributor specifications with package details, application guidance, engineering considerations, and a transparent assessment of drop-in replacement availability. That information helps buyers evaluate the ATTINY167-MU beyond basic catalog parameters while clearly identifying specifications and equivalent parts that could not be verified from the supplied sources.

Typical uses include LIN-connected automotive accessory modules, compact sensor interfaces, building-control nodes, lighting-control modules, and small industrial automation products. The combination of 16 KB Flash and a LIN controller is particularly useful in distributed networks where each node requires local firmware, nonvolatile configuration storage, and reliable low-speed communication. When designing the PCB, assign every pin through the manufacturer pin-description table and reserve programming-test access for ISP programming and debugging. Follow the recommended input, output, and decoupling capacitor arrangement, and verify external clock requirements before selecting oscillator components. Because 512 bytes of SRAM is modest, use efficient buffers and avoid unnecessarily large in-memory data structures. This product page combines the manufacturer specifications, package information, practical application guidance, and clearly qualified replacement analysis. The comparison and design notes focus on engineering differences that affect firmware compatibility, memory requirements, communications, layout, and production sourcing rather than simply repeating a catalog summary.

The 512-byte SRAM is suitable for small control loops, state machines, communication buffers, and mixed analog-digital logic, while the 512-byte EEPROM preserves calibration values, configuration settings, counters, or product data when power is removed. Typical applications include compact industrial controllers, low-power sensor nodes, building and appliance controls, LED drivers, compact power-conversion controllers, and small motor-control systems. It is especially useful where an 8-bit architecture, deterministic peripheral timing, and space-efficient TSSOP packaging are more valuable than the processing power of a 32-bit MCU. PCB implementation should preserve access to the programming interface and provide the decoupling and clock arrangement specified by the manufacturer datasheet. Confirm ADC, timer, and communication pin assignments before fixing the board layout because peripheral functions can share I/O pins. For battery-powered equipment, calculate the average current from active-mode and power-sleep behavior rather than relying only on the maximum clock frequency. This page combines the ATTINY167-XU electrical characteristics, drop-in replacement guidance, application analysis, and design notes to support faster component selection and PCB implementation.

ATTINY20-UUR - 12MHz AVR MCU, 2KB Flash | Microchip

Microchip Technology ATTINY20-UUR is an 8-bit AVR RISC-based microcontroller operating at up to 12MHz, with 2KB of in-system programmable Flash memory, 128 bytes of SRAM, and 12 general-purpose I/O lines in a 12-ball WLCSP package measuring 1.56mm by 1.4mm. The device also provides 16 general-purpose working registers and an 8-bit timer/counter with two PWM channels. A microcontroller is a compact programmable control component that integrates a processor core, nonvolatile program memory, working memory, and peripherals into one package. The ATtiny20 belongs to the AVR family of 8-bit RISC microcontrollers, which sit within the broader hierarchy of embedded processors and semiconductor devices. Its compact package and mixed-signal peripherals are useful for space-constrained embedded-control products that need deterministic local processing without a larger microcontroller. The ATTINY20-UUR supports up to 12 MIPS throughput through a high-performance, low-power AVR architecture. Its 112-instruction set and most single-clock-cycle execution capability suit compact control loops, simple serial communication, and peripheral control. Program storage is organized as 2KB of Flash, while the 128-byte SRAM provides volatile working space. Twelve I/O lines allow the device to connect to sensors, indicators, actuators, and external control interfaces within a small board area. The ATtiny20 family combines an 8-bit timer/counter with two PWM channels and a 16-bit timer/counter with a 10-bit comparator, according to the verified Microchip product-page data. These timers support periodic event generation, timing, and proportional control functions. The family operates from 1.8V to 5.5V, as identified in the verified comparison data, making it suitable for systems whose available supply voltage falls within that range. Typical uses include compact consumer accessories, sensor-interface modules, LED and lighting controls, small motor-control functions, industrial control nodes, and embedded household products. The 12-ball WLCSP format is especially useful when minimizing component footprint is more important than using a leaded package. Designers should still plan PCB assembly and inspection around the very small ball pitch and provide suitable bypass capacitance close to the supply pins. A principal design consideration is that the 2KB Flash capacity is intentionally modest. Code must be selected to fit available program memory, while the 128-byte SRAM requires careful attention to stack depth and buffer allocation. Firmware that otherwise fits can exceed practical memory constraints when interrupt handlers, libraries, and diagnostic code are added. A precise WLCSP land pattern, verified programming setup, and manufacturer-recommended decoupling are therefore essential to a reliable implementation. This product record combines verified Microchip specifications, distributor availability and pricing references, package information, replacement analysis, and practical implementation guidance. It is intended to help engineers determine whether the ATtiny20's small memory footprint and compact 12-ball WLCSP package meet the needs of a specific embedded-control design.

It is functionally safety (FuSa) capable and features a hardware multiplier, Event System, SleepWalking peripherals, and accurate analog peripherals including a 10-bit ADC. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, RAM, I/O peripherals, and often analog blocks onto one silicon die. The ATTINY204 belongs to the tinyAVR 0 family, the smallest and most power-efficient subfamily of the 8-bit AVR RISC architecture introduced by Atmel (now Microchip). tinyAVR 0 sits within the hierarchy: microcontroller -> embedded controller -> 8-bit MCU -> AVR -> tinyAVR -> tinyAVR 0-series, and is positioned for cost- and pin-constrained designs where full-size ATmega or ATtiny 1-series MCUs are too large. Key differentiating features include a 10-bit ADC with up to 12 channels, configurable custom logic (CCL), and a 16-bit Timer/Counter type A with three compare channels for PWM generation. The device runs from 1.8 V to 5.5 V and supports Sleep modes drawing under 1 uA. The Event System and SleepWalking allow peripherals to operate autonomously without waking the CPU, an essential feature for battery-powered and energy-harvesting applications. Architecturally, the ATTINY204 uses the classic AVR RISC core with single-level pipelining and most instructions executing in a single clock cycle. A hardware multiplier accelerates 8-bit by 8-bit multiplications to two cycles. The Flash, SRAM, and EEPROM are mapped on a unified address bus with EEPROM accessed through a dedicated peripheral, simplifying wear-leveling application code. Typical applications include low-power IoT sensor nodes, LED lighting controls, capacitive touch user interfaces, consumer remote controls, and battery-powered wearables. In each scenario, the small 14-pin footprint combined with flexible peripherals allows PCB space below 25 mm x 25 mm. A key design consideration is the maximum operating voltage: 5.5 V absolute maximum. Designers must ensure VDD never exceeds this limit, including during hot-plug or USB bus-powered events. Decoupling with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin is recommended.

The device consumes only a few microamperes in active mode and drops into sub-microamp sleep modes with peripheral interrupts, allowing battery-powered designs to run for years from a single cell. Internal 20 MHz calibrated oscillator eliminates the need for an external crystal in many designs. Typical applications include battery management ICs, LED drivers, sensor node controllers, home automation endpoints, capacitive-touch user interfaces, and industrial sensor transmitters. The SOIC-8 footprint simplifies hand-soldering and rework on 2-layer boards while remaining compatible with automated pick-and-place assembly. The wide 1.8 V to 5.5 V operating range allows direct connection to single-cell Li-ion, two-cell alkaline, or 3.3 V/5 V system rails without level shifting. When designing with the ATTINY212-SSN, allocate sufficient decoupling (100 nF close to VDD) and follow the datasheet's recommended UPDI programming pinout for in-system updates. The 20-pin-functional-mode multiplexing requires careful pin-function selection early in the firmware architecture to avoid late-stage rework.

Architecturally, the ATtiny2313A uses a 32 x 8-bit general-purpose working register file directly connected to the ALU, allowing two independent registers to be accessed in one cycle. The program memory is organized as 1K x 16 bits (Flash) and the device includes a true Read-While-Write self-programming mechanism via the on-chip boot block, which simplifies in-field firmware updates. The USART supports both asynchronous and synchronous modes with fractional baud-rate generator, and the USI module can act as SPI master/slave or TWI master/slave. Typical applications include USB-to-serial bridge replacements, IR remote control transmitters and receivers, consumer appliance controllers, simple sensor hubs, LED lighting controllers, and compact logic-replacement subsystems. The wide voltage range and low-power sleep modes also make it attractive for battery-driven products such as wireless sensor nodes, smart locks, and wearables. When designing with this part, choose the internal calibrated RC oscillator for cost- and pin-sensitive designs, or add an external crystal on PB4/XTAL1 and PB5/XTAL2 when frequency accuracy matters. Decouple VCC (pins 1 and 19) with a 100nF ceramic capacitor placed within a few millimeters of the supply pins, and keep ISP programming traces short to avoid disrupting the debugWIRE interface during bring-up. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet, including explicit guidance on choosing ATtiny2313A-SU versus the pin-compatible ATtiny4313-SU and ATTINY2313A-PU DIP-package variant.

Distributor listings identify the device as a 6-pin SOT-23-6 part and indicate support for 2.5 V, 3.3 V, and 5 V supply variants. Its small package makes it suitable for board-constrained products, but designers should verify the exact electrical limits and pin functions against the manufacturer documentation before layout or firmware release. The ATTINY4-TSHR is positioned for simple control logic rather than high-throughput embedded processing. Its limited memory footprint favors compact programs, state machines, debounce logic, indicators, and basic timing functions. The device can be evaluated for simple sensor conditioning, low-speed communication, actuator control, and auxiliary system functions where the application does not require large buffers or complex networking. Typical design work should begin by confirming the supply voltage, oscillator configuration, I/O direction, reset behavior, and programming interface. Because the package has only six pins, pin multiplexing and exposed-pad or programming considerations require careful schematic review. Use the manufacturer datasheet as the authoritative source for pin names, electrical limits, programming requirements, and operating conditions. A key selection consideration is that ATTINY4-TSHR is a highly constrained MCU with only 512 bytes of Flash and 32 bytes of SRAM. Choose it when the control task is simple and board area is more important than memory capacity or peripheral breadth. For designs needing larger firmware storage, more SRAM, or a broader peripheral set, compare the ATtiny family or another microcontroller family rather than assuming this part can scale. This page combines verified distributor specifications, manufacturer and datasheet references, application guidance, and same-family comparison information to support practical selection.

Its two PWM channels can support timing, dimming, or basic proportional actuator functions, while the 12 I/O lines provide flexibility for switches, indicators, sensors, and external logic. When designing a PCB, reserve the programming and reset connections, route clock and decoupling pins according to the manufacturer reference layout, and confirm that every external signal remains within the device’s verified voltage limits. Because the verified snippets do not supply a numerical operating-voltage range, ADC resolution, pin electrical limits, or package dimensions, those values must be checked in the official ATtiny40 documentation before release to manufacturing. This product page combines verified Microchip and distributor data, source-backed availability links, practical application guidance, and explicit data-gap markers. It does not infer unverified electrical specifications or present functional comparators as drop-in replacements when pin or peripheral compatibility has not been demonstrated.

ATTINY40-SUR - 12MHz 8-Bit AVR MCU, 4KB Flash | Microchip (Tape & Reel)

The Microchip Technology ATTINY40-SUR is a low-power CMOS 8-bit AVR microcontroller with 4 KB In-System Programming Flash memory, 256 B SRAM, 12 general-purpose I/O lines, and a maximum clock frequency of 12 MHz, all housed in a 20-pin SOIC package. It executes the compact AVR enhanced RISC architecture and combines 16 general-purpose working registers with an 8-bit timer/counter featuring two PWM channels. An 8-bit AVR microcontroller is a compact embedded controller that executes firmware instructions on a Harvard-style architecture, balancing processing capability, memory efficiency, and low power consumption. The AVR family belongs to the broader hierarchy of microcontrollers, embedded processors, and semiconductors. TinyAVR devices are particularly useful for cost-sensitive control, monitoring, signal-generation, and communication tasks where a larger MCU would add unnecessary cost or board area. Key verified features include 4 KB flash organized as 2K by 16 words, 256 B SRAM, 12 I/O lines, 16 working registers, and an 8-bit timer/counter with two PWM channels. Its 12 MHz maximum frequency provides substantially more instruction throughput than lower-clock ATtiny devices. The 20-pin SOIC package also supports conventional surface-mount assembly while exposing enough pins for power, clock, programming, reset, I/O, and timer functions. The AVR enhanced RISC architecture supports efficient execution of firmware commonly written for AVR-compatible toolchains. The processor architecture and instruction set should be reviewed against the manufacturer datasheet before porting code, especially when the replacement MCU has a different instruction set, peripheral arrangement, interrupt vector table, or programming interface.
