Microchip ATMEGA2561V-8AUR 8-bit AVR Microcontroller Overview

The Microchip ATMEGA2561V-8AUR is a high-performance, low-power 8-bit microcontroller based on the enhanced AVR RISC architecture. This powerful MCU is engineered to deliver a robust combination of processing capability, extensive peripheral integration, and energy efficiency, making it a premier choice for complex embedded applications ranging from industrial automation and automotive systems to advanced consumer electronics.

Operating at a maximum frequency of 8 MHz with a supply voltage as low as 1.8V (the "-8AU" suffix denoting 8MHz at 1.8V-5.5V), this variant is particularly optimized for low-power applications. Its core can execute powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz, allowing system designers to balance processing speed against power consumption effectively.

A defining feature of the ATmega2561 is its massive memory resources. It is equipped with 256 KB of in-system self-programmable Flash memory, which is substantial for an 8-bit controller, enabling the storage of large and sophisticated application code. This is complemented by 8 KB of SRAM for efficient data handling and 4 KB of EEPROM for non-volatile storage of critical data, ensuring data retention even when power is cycled.

The peripheral set of this microcontroller is exceptionally rich. It includes:

Four 8-bit timers/counters and four 16-bit timers/counters with separate prescalers and compare modes.

Hardware Real-Time Counter (RTC) for precise timing operations.

Two 8-channel, 10-bit ADCs for high-fidelity analog signal acquisition.

Dual USARTs, SPI, and I2C (TWI) interfaces for versatile serial communication.

JTAG interface for on-chip debugging and boundary-scan capabilities, significantly accelerating development and testing cycles.

Housed in a 64-pin TQFP package, the device offers a multitude of I/O lines to interface with sensors, actuators, and other external components. Its advanced architecture includes a JTAG-enabled debugWIRE on-chip debug system, which provides cost-effective debugging and programming without consuming system resources.

ICGOODFIND: The Microchip ATMEGA2561V-8AUR stands out as a highly integrated and powerful 8-bit microcontroller. Its exceptional memory size, comprehensive peripheral suite, and focus on low-voltage, low-power operation make it an ideal solution for demanding embedded control applications where processing complexity, connectivity, and energy efficiency are paramount.
