Product Overview

The ATMEGA2561-16AU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 256kB ISP flash memory, 8kB SRAM, 4kB EEPROM, 86 general purpose I/O lines, 32 general purpose working registers, real time counter, six flexible timers/counters with compare modes, PWM, 4 USARTs, byte oriented 2-wire serial interface, 8-channel 10-bit A/D converter and a JTAG interface for on-chip debugging. The device achieves a throughput of 16MIPS at 16MHz and operates between 4.5 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves a throughput approaching 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using Atmel’s high density nonvolatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an on-chip boot program running on the AVR core.
  • Advanced RISC architecture
  • Power-on reset and programmable brown-out detection
  • Internal calibrated RC oscillator
  • External and internal interrupt sources
  • Six sleep modes - idle, ADC noise reduction, power-save, power-down, standby and extended standby
  • 135 Powerful instructions-most single clock cycle execution
  • 32 x 8 General purpose working registers
  • Fully static operation
  • Up to 16MIPS throughput at 16MHz
  • On-chip 2-cycle multiplier
  • QTouch® library support
  • Programmable watchdog timer with separate on-chip oscillator
  • On-chip analog comparator
  • Interrupt and wake-up on pin change
  • Byte oriented 2-wire serial interface
  • JTAG (IEEE® std. 1149.1 compliant) Interface
  • Output compare modulator
  • Master/Slave SPI serial interface
