The C165 is a processor oriented version within our C166 microcontroller family. It meets the demands of embedded applications with high-end real-time requirements and large data throughput where pricing is a sensitive factor, for example in dataprocessing and telecom products. The fastest version of the C165, the SAB-C165-L25M, needs just 80 ns at 25 MHz CPU clock to process each instruction. The C165 can operate at voltages down to 3.0V reducing the power consumption in battery-powered applications. Two surface mount packages are available; MQFP-100 and TQFP-100.
