ATMEL ATMEGA2560V-8AU 8-bit Microcontroller, 256KB Flash, 100-Pin TQFP

The ATMEL ATMEGA2560V-8AU is a high-performance, low-power 8-bit AVR RISC-based microcontroller, engineered for demanding industrial and embedded applications. It combines substantial on-chip memory with a rich set of peripherals, offering an ideal balance of processing power and energy efficiency for complex control systems.

At its core, the device features 256KB of in-system programmable (ISP) flash memory for code storage, 8KB of SRAM for data, and 4KB of EEPROM for non-volatile parameter storage. The advanced RISC architecture, with its 32 general-purpose working registers all directly connected to the Arithmetic Logic Unit (ALU), enables the execution of powerful instructions in a single clock cycle, achieving a throughput of up to 16 MIPS at 16 MHz.

Comprehensive Peripheral Set

• Connectivity: Provides extensive I/O with 86 general-purpose lines and multiple communication interfaces including 4 USARTs, a byte-oriented 2-wire serial interface (I2C), and a JTAG interface for robust on-chip debugging.
• Analogue & Timing: Integrates a 16-channel, 10-bit analogue-to-digital converter for precision sensing and six flexible timer/counters with compare modes and PWM functionality for motor control and waveform generation.
• System Management: Includes a real-time counter with a separate oscillator, power-on reset, programmable brown-out detection, an internal calibrated oscillator, and multiple internal and external interrupt sources for reliable system operation.

Power Management & Robustness

Designed for reliability in industrial environments, the microcontroller supports six sleep modes—Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby—to minimise power consumption. It operates across a wide industrial temperature range from -40°C to +85°C and a supply voltage range from 1.8V to 5.5V. Additional features include an on-chip 2-cycle hardware,
