ATTINY12-8PU

ATTINY12-8PU - 8-Bit 1KB Flash AVR MCU, 8MHz | Microchip

The Microchip Technology ATTINY12-8PU is an 8-bit AVR RISC microcontroller with 1KB of Flash program memory, 64 bytes of EEPROM, 6 I/O ports, and an 8MHz maximum clock speed, supplied in an 8-pin PDIP package for 4V to 5.5V operation. It is designed for compact embedded control tasks where a small flash footprint, simple 8-pin footprint, and low component count are more important than extensive peripheral integration. An 8-bit AVR microcontroller is a reduced-complexity processor within the broader semiconductor and embedded-controller hierarchy. The ATTINY12 combines an AVR RISC core, Flash program memory, EEPROM data memory, general-purpose I/O, and an internal oscillator in one device. Its PDIP package also provides through-hole compatibility for prototyping, educational assemblies, and repair applications where a surface-mount package would be inconvenient. The ATTINY12-8PU provides 1KB of Flash memory organized as 512 x 16, 64 bytes of EEPROM, and 6 I/O ports. Its listed operating voltage range is 4V to 5.5V, with a maximum operating frequency of 8MHz. The device uses the AVR RISC architecture and is described as offering 90 powerful instructions with most instructions executing in a single clock cycle. Typical use cases include small sensor nodes, simple timers, LED indicators, basic control loops, teaching examples, and dedicated appliance controllers. Because the device has only 1KB of Flash and 64 bytes of EEPROM, it is best suited to compact firmware with limited buffering, calibration storage, and peripheral integration. It should not be selected when the design requires extensive code space, high-resolution ADC conversion, or a large number of I/O pins. The most important design consideration is supply-voltage margin. Operating from a nominal 5V rail requires the rail to remain within the stated 4V to 5.5V range, including transient and regulator tolerance. Designers should also account for the limited memory before adding libraries, and should confirm the exact pin function and startup behavior against the manufacturer datasheet when replacing a different DIP-8 device. This page combines distributor availability, verified device parameters, same-package replacement guidance, and application-specific design notes. It is intended to help engineers identify whether the ATTINY12-8PU is suitable for a new design or whether a higher-memory ATtiny family member should be selected instead.

ATTINY12-8SI - 8-Bit AVR, 8MHz, 1KB Flash | Microchip Technology
ATTINY12-8SI

ATTINY12-8SI - 8-Bit AVR, 8MHz, 1KB Flash | Microchip Technology

Microchip Technology ATTINY12-8SI is an 8-bit AVR ATtiny microcontroller operating at 8MHz, with 1KB of Flash program memory organized as 512 x 16 words and 64 bytes of EEPROM data memory. The device is offered in an 8-pin SOIC package and is identified as an industrial-temperature variant. A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, data memory, and digital input/output circuitry on one device. The ATTINY12-8SI belongs to the ATtiny family, within the broader AVR microcontroller and embedded-controller hierarchy. Its small memory capacity and limited pin count make it suitable for compact control tasks rather than general-purpose applications requiring extensive code storage or peripheral connectivity. The principal characteristics include an 8-bit AVR core, 8MHz clock rating, 1KB Flash memory, 64 bytes of EEPROM, and an 8-SOIC package. These parameters support small embedded routines such as state sequencing, simple signal generation, switching control, and basic logic coordination. The 512-word Flash organization provides 1KB of code storage, while the EEPROM provides a small amount of nonvolatile data storage separate from program memory. The ATtiny12 architecture places significant emphasis on compact implementation. With only eight pins, external signal allocation requires careful pin planning, and the available GPIO resources are limited compared with larger ATtiny devices. Program development must therefore remain compact, and peripheral functions must be selected around the actual pin requirements of the target circuit. The 8MHz maximum clock supports faster execution than lower-speed microcontrollers while retaining a straightforward embedded-control architecture. Typical uses include small industrial control modules, LED sequencing and lighting controllers, compact timers, simple sensor interfaces, and auxiliary control functions in larger equipment. It is most appropriate where the firmware can fit within 1KB and only a small number of external signals is required. Designs needing serial communication, larger data storage, more I/O, or substantially more program memory should use a higher-capacity microcontroller instead. For PCB implementation, place the decoupling capacitor close to the VCC pin and route the ground connection with minimal resistance. Confirm every use of the reset-capable and ADC-capable pins against the manufacturer pin-description table, especially when the package footprint is shared with another ATtiny family member. The industrial-temperature ordering code must also be confirmed against the system’s environmental requirements before release to production. This product page combines the manufacturer identity, core operating parameters, memory configuration, package information, application guidance, and qualified drop-in alternatives into one engineering reference. It also highlights the limits of the ATTINY12-8SI so purchasing teams can distinguish genuine pin-compatible replacements from larger microcontrollers that share the SOIC-8 format but require different firmware, pin assignments, or peripheral resources.

The device operates across a 1.8 V to 5.5 V supply range and achieves up to 20 MIPS throughput at a 20 MHz clock, letting designers trade power consumption for processing speed on the fly. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile memory (Flash/ROM), volatile working memory (SRAM), and a configurable set of peripherals such as timers, ADCs, and digital I/O onto one IC. MCUs form the lowest tier of embedded computing, sitting beneath microprocessors (MPUs) and application processors in capability but above fixed-function logic ICs in flexibility. The AVR family places a RISC-style load/store CPU core next to tightly-coupled peripherals, and the tinyAVR sub-family scales this architecture into the smallest 8-pin parts for cost- and space-sensitive designs. Key features include hardware multipliers-free single-cycle execution, a debugWIRE on-chip debug interface, an analog comparator, a programmable watchdog timer with separate on-chip oscillator, and two PWM-capable 8-bit timers plus one high-speed timer. The picoPower technology extends battery life through multiple sleep modes that drop active current to the microamp range. Six general-purpose I/O lines are available on the SO-8 footprint, with PB5 serving as the reset pin and supporting in-circuit serial programming. Architecturally, the ATTINY13A-SSU fuses an enhanced RISC core (90+ instructions, most single-cycle) with a Harvard-style memory layout that lets the CPU fetch instructions from Flash while data accesses hit SRAM in the same cycle. The peripheral set is selected for analog and digital mixed-signal chores: a 10-bit successive-approximation ADC with four input channels, a programmable analog comparator, and dedicated timer/counter blocks with PWM output match units for switching tasks. Typical applications include LED drivers, battery chargers, small motor controls, remote control transmitters, simple sensor nodes, and wearable accessories where board area and quiescent current are constrained. The wide 1.8 V to 5.5 V range lets a single design migrate between single-cell lithium and 3.3 V or 5 V system rails without hardware changes. When laying out a board, place the decoupling capacitor (typically 100 nF) within a few millimetres of the VCC pin and route a low-impedance GND pour under the exposed copper area to keep digital switching noise out of the ADC inputs. Ensure the RESET pin (PB5) is pulled high through 10 kohm and accessible to the ISP header so in-circuit programming and debugWIRE debug sessions can be performed without removing the part.

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.

A 16 MHz operating clock supports deterministic control in compact embedded products, and the 20-pin SOIC package simplifies assembly on conventional through-hole PCB layouts. The device is based on the low-power CMOS AVR enhanced RISC architecture and integrates an 8-bit timer/counter with compare modes. Serial interfaces support communication with sensors, transceivers, actuators, and service connectors. Because Flash, EEPROM, SRAM, I/O, timing, and communications share one package, the ATTINY167-SU can reduce board area and component count compared with discrete control solutions. 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.

ATTINY167-XU - 16MHz 16KB AVR Microcontroller | Microchip

The Microchip Technology ATTINY167-XU is an 8-bit AVR RISC-based microcontroller with 16 KB of ISP Flash memory, 512 bytes of EEPROM, 512 bytes of SRAM, and up to 16 general-purpose I/O lines. It operates at up to 16 MHz and is offered in a 20-pin TSSOP package for compact embedded-control designs. An AVR microcontroller is a low-power programmable controller built around the AVR RISC instruction set. Its place in the product hierarchy is microcontroller > embedded controller > semiconductor, while the ATTINY167 belongs to the ATtiny family of small 8-bit RISC microcontrollers. These devices combine digital control, timers, serial interfaces, and analog functions in one integrated package, allowing compact products to replace combinations of discrete logic and analog components. Key features include 16 KB of ISP Flash program memory, 512 bytes of EEPROM, 512 bytes of SRAM, 32 general-purpose working registers, and an 8-bit timer/counter with compare modes. The device also provides a high-speed timer/counter, supporting applications that require precise timing, periodic events, input capture, or waveform generation. Its 16 general-purpose I/O lines provide flexible connections for switches, sensors, indicators, actuators, and communication peripherals. The ATTINY167 combines a high-performance 8-bit RISC core with on-chip nonvolatile storage and a compact peripheral set. ISP programming supports in-system firmware updates when the circuit provides the required programming access. 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-CCU

ATTINY20-CCU - 8-bit AVR MCU, 2KB Flash, 15-UFBGA | Microchip

The Microchip Technology ATTINY20-CCU is an 8-bit AVR RISC microcontroller with 2 KB of in-system programmable Flash memory, 128 bytes of SRAM, and 12 general-purpose I/O lines. It operates at up to 12 MHz and is packaged in a 15-UFBGA 3x3 mm package for space-constrained embedded designs. An 8-bit AVR microcontroller is a compact RISC-based controller that executes most instructions within a single clock cycle. The ATTINY20 belongs to the TinyAVR family, combining low-power operation with timer, counter, ADC, and PWM resources in a small package. Its architecture follows the MCU hierarchy from application-specific controller to embedded processor, RISC microcontroller, and integrated circuit. The device provides 2 KB of ISP Flash for program storage and 128 bytes of SRAM for working memory. Its 12 I/O lines support digital control and multiplexing functions, while the 16 general-purpose working registers support efficient register-based execution. Peripheral resources include an 8-bit timer/counter with two PWM channels, a 16-bit timer, and a 2-channel 10-bit ADC, according to the Microchip ATtiny20 product page. The ATtiny20 uses the compact AVR enhanced RISC architecture and can approach 1 MIPS per MHz under suitable instruction conditions. ISP programming permits firmware updates without removing the device from a finished assembly, which simplifies production programming, in-system upgrades, and low-volume manufacturing. Its 15-UFBGA package reduces board area compared with leaded or larger-surface-mount packages, although board layout and prototyping require fine-pitch assembly capability. Typical uses include compact sensor controllers, LED lighting modules, battery-powered monitoring devices, simple motor or fan controls, and embedded keypad interfaces. The two PWM channels can drive indicators or small mechanical loads, the ADC supports analog sensing, and the GPIO count is suitable for modest control loops where a larger MCU would be unnecessary. Designers should confirm the exact pin mapping and exposed-pad requirements against the manufacturer datasheet before layout because no compatible package SVG was available for verification. Firmware must also fit within 2 KB, and applications must account for the limited 128-byte SRAM. The 3x3 mm land pattern is mechanically compact but requires careful reflow control and inspection. This page consolidates the verified ATtiny20 family specifications, distributor inventory and pricing, sourcing links, and design considerations that are not presented together on a manufacturer datasheet summary. It also documents the limited availability of verified pin-for-pin replacements for this unusually small 15-UFBGA configuration.
