It also provides 1 KB of SRAM and 128 bytes of EEPROM, making it suitable for compact embedded-control designs that need deterministic digital I/O, local program storage, and low-power operation. An 8-bit microcontroller is a programmable semiconductor containing a processor core, memory, and integrated peripherals on one device. Within the product hierarchy, the ATTINY826 belongs to the AVR family, the tinyAVR 2 series, and the broader embedded-microcontroller category. Unlike a discrete logic controller, it executes firmware that can implement timers, communication protocols, control sequences, and interface handling without requiring extensive external components. The ATTINY826 uses an AVR CPU with a hardware multiplier and can run at up to 20 MHz. Its 8 KB Flash capacity provides room for application code, while 1 KB of SRAM supports working variables and stack operations. Nonvolatile EEPROM preserves up to 128 bytes of calibration data, configuration values, or counters when the main supply is removed. The listed operating voltage options are 2.5 V, 3.3 V, and 5 V, supporting both low-voltage and conventional embedded-system rails. The -SU ordering code identifies a 20-pin SOIC package rated for industrial temperature operation to 85 °C. This surface-mount package is suitable for automated assembly and compact PCB layouts. The tinyAVR 2 family uses modern low-power design techniques and an Event System, allowing peripherals to communicate through events to reduce CPU intervention. Exact peripheral assignments, clock configurations, and current-consumption figures must be confirmed in the manufacturer datasheet. Typical uses for the ATTINY826-SU include compact industrial controllers, sensor-interface modules, low-power monitoring equipment, actuator-control boards, and small consumer devices. Its combination of 20 MHz processing, 8 KB Flash, and 1 KB SRAM makes it practical for modest control tasks that do not require a high pin count or large application memory. Designers should verify the exact pin multiplex, peripheral allocation, clock limits, and decoupling requirements against the manufacturer datasheet. A 20 MHz operating point requires suitable clock configuration and signal integrity, while production layouts should provide short return paths and stable supply filtering around the device. This page consolidates verified manufacturer and distributor information, pin-compatible family alternatives, pricing references, and practical selection guidance. It is intended to help engineers determine whether the ATTINY826-SU fits a specific embedded-control design before completing PCB and firmware validation.

ATTINY827-MF

ATTINY827-MF - 20MHz 8-bit AVR MCU, 8KB Flash, 24-VQFN | Microchip

The Microchip Technology ATTINY827-MF is an 8-bit AVR tinyAVR 2 family microcontroller built around the AVR CPU with hardware multiplier, running at up to 20 MHz, and integrating 8 KB of Flash program memory, 1 KB of SRAM and 128 bytes of EEPROM in a 24-pin VQFN (4 x 4 mm) package. A microcontroller is a self-contained computing element that integrates a CPU core, non-volatile program memory, working RAM and dedicated peripherals onto one die. The tinyAVR 2 family, to which the ATTINY827 belongs, extends that hierarchy from general-purpose MCU down to a compact 8-bit AVR core optimized for cost-sensitive embedded control. The ATTINY827 sits at the top of that family in memory density, giving small control boards real code space without moving to a 32-bit core. Key features of the ATTINY827-MF include a hardware multiplier in the CPU core, 8 KB of Flash for program storage, 1 KB of SRAM for data, and 128 bytes of EEPROM for non-volatile parameter retention. The family uses the latest Core Independent Peripherals (CIPs) from Microchip, and the ATtiny827 variant additionally carries the serial and timer resources typically required for connected control nodes. The 24-VQFN land pattern at 4 x 4 mm keeps the footprint smaller than the equivalent 20- and 24-lead SOIC options, saving board area in densely packed appliances and sensor modules. Because the CPU runs the classic AVR instruction set with a hardware multiplier, arithmetic-heavy loops such as PID updates or sensor compensation run without software multiplication routines. The tinyAVR 2 core combines that throughput with a low-power design that suits battery-operated and duty-cycled systems, while the CIP peripherals let functions such as timers, comparators and communication modules be routed to pins without heavily loading the CPU. Typical applications include small motor and pump controllers, LED lighting and signage drivers, battery-powered sensor nodes, appliance user-interface boards, and compact current-measurement or energy-metering sub-systems. In each case the part replaces a discrete logic solution while keeping bill-of-material cost and board area low. A key design consideration is that a 4 x 4 mm VQFN demands careful PCB layout: land patterns are dense, the exposed pad must be soldered and tied to ground for thermal performance, and the package has no lead room for hand rework. Use the pin description table in the Microchip ATtiny424/426/427/824/826/827 data sheet when assigning tracks. This page consolidates manufacturer specifications, package and pin-out guidance, family drop-in alternatives and practical layout notes into one place, adding engineering context that a bare parametric distributor listing does not provide.

The device includes an AVR CPU with a hardware multiplier and supports operating frequencies of 10 MHz at 2.7 V and 5 MHz at 1.8 V, providing design flexibility across common low-voltage supply rails. A microcontroller is a programmable integrated circuit that combines a processor core, nonvolatile program memory, data memory, and peripherals in one compact device. The ATTINY827 belongs to the hierarchy of tinyAVR 2-series microcontrollers, AVR 8-bit microcontrollers, embedded controllers, and integrated circuits. Its compact package makes it suitable for space-constrained control systems, while its hardware multiplier supports efficient multiplication operations in embedded software. The principal memory resources are 8 KB of Flash for firmware, 1 KB of SRAM for working data, and 128 bytes of EEPROM for nonvolatile data retention. Execution up to 20 MHz provides useful processing margin for event-driven control, monitoring, and communication-oriented firmware. The 24-pin VQFN arrangement also supports compact PCB construction in applications where the 4 x 4 mm footprint is valuable. The tinyAVR 2 family uses a flexible, low-power architecture and incorporates Core Independent Peripherals, as identified by the manufacturer product page. These characteristics make the ATTINY827-MU relevant to embedded designs that require deterministic low-power control without the memory and processing demand of a high-end application processor. Firmware designers should select the operating frequency and peripherals required by the target system from the complete family datasheet. Typical uses include compact industrial control modules, environmental monitoring nodes, LED and lighting controllers, consumer-product interfaces, and small embedded subsystems. Its 1 KB SRAM is suitable for modest control loops and protocol buffering, while 8 KB of Flash can hold focused application firmware. Designs requiring substantially larger code images, larger RAM buffers, or more high-speed peripherals should use a higher-density microcontroller. The primary design consideration is supply and layout planning. The MCU is specified for 10 MHz at 2.7 V and 5 MHz at 1.8 V, so the selected clock must remain valid at the worst-case supply voltage. A compact VQFN layout should also use manufacturer-recommended land patterns, adequate decoupling, clean grounding, and careful treatment of exposed-pad thermal requirements. This page consolidates the verified manufacturer and distributor information for ATTINY827-MU with practical selection guidance, application analysis, and transparent data-availability notes. It distinguishes confirmed specifications from unavailable parameters rather than inferring missing pin assignments, prices, or detailed peripheral characteristics.

ATTINY9-MAH - 8-Bit 12MHz AVR with 1KB Flash | Microchip

The Microchip Technology ATTINY9-MAH is an 8-bit AVR RISC-based microcontroller operating up to 12 MHz, with 1 KB of ISP Flash memory, 32 bytes of SRAM, and four general-purpose I/O lines. It is packaged in an 8-UFDFN exposed-pad package for compact, surface-mount embedded designs. The verified distributor data identifies the part as an ATtiny-series AVR device using an internal oscillator and supplied in bulk packaging. A microcontroller is a programmable integrated circuit that executes firmware to monitor inputs, control outputs, and manage system timing. In the broader semiconductor hierarchy, this device is an 8-bit microcontroller, part of the AVR family, and belongs to the embedded-control and power-management design ecosystem. The ATTINY9 is positioned for small control tasks where low memory capacity, low pin count, and simple timing are more important than a large peripheral set or high processing bandwidth. Verified specifications include 1 KB of program Flash, 32 bytes of SRAM, four I/O lines, a 12 MHz maximum speed, an internal oscillator, and a 16-bit timer/counter with two PWM channels. The manufacturer page also identifies 16 general-purpose working registers and power-on reset, PWM, and watchdog-related functionality. These resources support compact control loops, simple indicator systems, basic motor or actuator timing, and low-power embedded products. The 8-UFDFN package helps reduce board area compared with larger leaded or plastic packages, but its exposed pad and fine-pitch footprint require careful PCB layout, land-pattern verification, soldering controls, and thermal-via planning. Because the provided data does not specify the complete electrical operating range, pin names, memory-retention behavior, or detailed timing characteristics, those parameters are marked as needing verification rather than inferred. Typical uses include small sensor interfaces, simple timers, compact LED or indicator controllers, low-cost consumer accessories, and basic embedded control modules. The device is most appropriate when firmware and I/O requirements are modest and the board can be designed around its 1 KB Flash and 32-byte SRAM limits. For designs needing more memory, communication peripherals, or a larger package pin count, a different ATtiny device should be evaluated. For a new design, confirm the exact UFDFN footprint, exposed-pad connection, programming method, oscillator behavior, and device-specific electrical limits against the official Microchip documentation before layout release. This page combines verified distributor specifications with engineering guidance, while clearly separating confirmed data from parameters that require manufacturer-datasheet confirmation.
