Description

The AT90CAN128-16AU is a low-power CMOS 8-bit microcontroller from the Microcontroller Units (MCUs/MPUs/SOCs) product category. This microcontroller is based on the AVR enhanced RISC architecture, which executes powerful instructions in a single clock cycle. This allows the AT90CAN128 to achieve throughputs approaching 1 MIPS per MHz. This microcontroller provides the system designer with the flexibility to optimize power consumption versus processing speed.
