ATMEGA16A-AU

The ATMEGA16A-AU is a 16bit low power high performance CMOS microcontroller in 44 pin QFP package. The device features 16KB self-programming flash program memory, 1024B SRAM, 512byte EEPROM, 8 channel 10bit A/D converter and JTAG interface for on-chip debug. The device achieves 16 MIPS throughput at 16MHz at 2.7 to 5.5V operation. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, allowing users to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
