Product Summary

The ATMEGA16A-AU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA16A-AU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The ATMEGA16A-AU 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.


ATMEGA16A-AU absolute maximum ratings: (1)Operating Temperature: -55 to +125℃; (2)Storage Temperature: -65 to +150℃; (3)Voltage on any Pin except RESET; (4)with respect to Ground: -0.5V to VCC+0.5V; (5)Voltage on RESET with respect to Ground: -0.5V to +13.0V; (6)Maximum Operating Voltage: 6.0V; (7)DC Current per I/O Pin: 40.0 mA; (8)DC Current VCC and GND Pins: 200.0mA PDIP and 400.0mA TQFP/MLF.
