Microchip ATTINY2313A-MUR: A Comprehensive Technical Overview

The Microchip ATTINY2313A-MUR stands as a robust and highly integrated 8-bit microcontroller, engineered to deliver performance and flexibility for a vast array of embedded control applications. Housed in a compact 20-pin QFN package, this AVR-based MCU is particularly suited for space-constrained designs requiring a rich set of features without sacrificing power efficiency.

At the core of the ATTINY2313A-MUR lies a high-performance AVR RISC architecture. The CPU can execute powerful instructions in a single clock cycle, achieving a throughput approaching 1 MIPS per MHz, which allows the system designer to optimize power consumption versus processing speed. The device operates over a wide voltage range, typically from 1.8V to 5.5V, making it an excellent choice for both battery-powered and line-operated products. Its enhanced pnanoPower technology ensures that active and sleep currents are minimized, extending operational life in energy-sensitive applications.

A key strength of this microcontroller is its abundant and versatile set of peripherals. It features 2KB of self-programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. The inclusion of 18 programmable I/O lines offers ample connectivity for sensors, actuators, and communication interfaces. For analog needs, it is equipped with a 10-bit ADC (Analog-to-Digital Converter) with 11 single-ended channels, enabling precise measurement of analog signals.

Communication is well-catered for with a full-duplex USART (Universal Synchronous and Asynchronous serial Receiver and Transmitter), which is invaluable for establishing serial communication links (e.g., RS-485, RS-232, or with other MCUs). Additionally, it features a versatile Serial Peripheral Interface (SPI) and a Two-wire Serial Interface (I2C compatible), providing multiple pathways for system expansion and inter-IC communication.

The ATTINY2313A-MUR also excels in timing and control functions. It includes two 8-bit timers/counters with separate prescalers and compare modes, and one 16-bit timer/counter with prescaler, capture mode, and compare mode. These are crucial for generating precise PWM outputs, measuring intervals, or creating real-time responses. A built-in programmable watchdog timer with a separate on-chip oscillator enhances system reliability by recovering from code malfunctions.

Its robust industrial temperature range (-40°C to +85°C) and high noise immunity make it a dependable choice for automotive, industrial, and consumer environments. The "-MUR" suffix denotes a tape and reel packaging for high-volume, automated assembly.

ICGOODFIND: The ATTINY2313A-MUR is a quintessential example of high integration and efficiency in a minimal footprint. Its blend of the proven AVR core, extensive peripheral set including USART and ADC, ultra-low power capabilities, and industrial robustness makes it an exceptionally versatile and reliable solution for cost-sensitive, compact embedded designs.
