Product Summary

The ATMEGA32L8AU 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 ATMEGA32L8AU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Parametrics

ATMEGA32L8AU absolute maximum ratings: (1)Voltage on any Pin except RESET with respect to Ground:-0.5V to VCC+0.5V; (2)Voltage on RESET with respect to Ground:-0.5V to +13.0V; (3)Maximum Operating Voltage:6.0V; (4)DC Current per I/O Pin:40.0 mA; (5)DC Current VCC and GND Pins:200.0 mA and 400.0 mA TQFP/MLF; (6)Operating Temperature:-55°C to +125°C; (7)Storage Temperature:-65°C to +150°C.
