ATTINY48-MU
ATTINY48-MU - 4KB 12MHz AVR MCU | Microchip Technology
The Microchip Technology ATTINY48-MU is a low-power picoPower 8-bit AVR RISC microcontroller with 4 KB of in-system programmable Flash, 64 B of EEPROM, 256 B of SRAM, and a maximum clock frequency of 12 MHz, housed in a 32-VQFN package measuring 5 x 5 mm.
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, timers, communication interfaces, and analog peripherals on one integrated circuit. In the broader hierarchy, the ATTINY48 belongs to the AVR enhanced RISC family of 8-bit embedded microcontrollers, with features suitable for compact control, sensing, and communications designs. Its 1.8 V to 5.5 V operating range supports both low-voltage and conventional 5 V systems.
The device provides up to 12 MIPS throughput at 12 MHz and executes powerful instructions in a single clock cycle. Integrated resources include an 8-bit timer/counter, a 16-bit timer/counter with PWM, a 10-bit analog-to-digital converter, SPI, and debugWIRE for on-chip debugging. The 4 KB Flash memory is organized as 2K x 16 according to the verified distributor data, while the 64 B EEPROM preserves nonvolatile data and the 256 B SRAM supports working memory.
The ATTINY48-MU combines an 8-bit RISC core with multiple mixed-signal peripherals in a compact 32-pin surface-mount package. Its picoPower architecture targets low-power embedded operation, making clocking, peripheral shutdown, and sleep-mode planning important during firmware development. The 10-bit ADC supports analog measurement, while SPI supports communication with sensors, displays, memory, and other digital peripherals.
Typical applications include low-power sensor nodes, industrial control modules, compact motor controllers, metering equipment, simple communication hubs, and embedded automation. The 12 MHz operating point is useful when firmware requires more timing headroom than a low-clock microcontroller while retaining a modest 8-bit processing footprint. The 5 x 5 mm VQFN package also supports dense board layouts where reduced footprint and careful exposed-pad thermal management are priorities.
For new layouts, follow the manufacturer package and pin-assignment documentation exactly, connect the exposed pad to the intended thermal and electrical plane, and validate the power, decoupling, programming, and debug interfaces before layout release. Firmware should also verify analog reference, timer prescaling, peripheral clock gating, and unused-pin states. This page combines verified product, distributor, application, and design information to support component selection without treating unverified alternatives as drop-in replacements.
