Microchip ATTINY2313A-SUR: An 8-bit AVR Microcontroller for Compact Embedded Systems

In the realm of embedded design, where constraints of space, power, and cost are paramount, the selection of the right microcontroller is a critical decision. The Microchip ATTINY2313A-SUR stands out as a powerful and versatile 8-bit AVR microcontroller engineered specifically for such compact and efficient applications.

This robust MCU is built on the well-established and highly efficient AVR RISC architecture. Its core can execute a single instruction per clock cycle, allowing it to achieve a throughput of up to 20 MIPS at 20 MHz, which provides substantial processing power for a chip of its size. This makes it capable of handling complex control tasks, sensor data processing, and user interface management in real-time.

A key strength of the ATTINY2313A lies in its memory configuration and peripheral set, meticulously designed for embedded control. It features 2KB of self-programmable Flash memory for flexible application code storage, 128 bytes of EEPROM for retaining critical data without power, and 128 bytes of SRAM. Its rich suite of integrated peripherals includes a versatile USART (Universal Synchronous/Asynchronous Receiver/Transmitter) for serial communication (e.g., RS-232, SPI), two 8-bit timers/counters, one 16-bit timer/counter, and 18 programmable I/O lines. This high level of integration allows designers to create full-featured applications with minimal external components, drastically reducing the overall system footprint and bill of materials.

The "SUR" suffix denotes that this component is supplied in a compact 20-pin SOIC (Small Outline Integrated Circuit) package, making it an ideal choice for space-constrained PCB designs. Furthermore, it is characterized for industrial and extended temperature ranges, ensuring reliable operation in demanding environments. With its focus on low power consumption across active, idle, and power-down modes, it is also perfectly suited for battery-operated devices.

Typical applications that benefit from the ATTINY2313A-SUR's profile include:

Appliance Control (e.g., microwaves, washing machines)

Consumer Electronics (remote controls, toys, smart sensors)

Industrial Automation (sensors, actuators, control panels)

Peripheral Interface Controller for larger systems
