Product Summary

The DS80C320QCL is a fast 80C31/80C32-compatible microcontroller. Wasted clock and memory cycles have been removed using a redesigned processor core. As a result, every 8051 instruction is executed between 1.5 and 3 times faster than the original for the same crystal speed. Typical applications will see a speed improvement of 2.5 times using the same code and same crystal. The DS80C320QCL offers a maximum crystal rate of 33 MHz, resulting in apparent execution speeds of 82.5 MHz (approximately 2.5X). The DS80C320QCL is pin-compatible with all three packages of the standard 80C32 and offers the same timer/counters, serial port, and I/O ports. In short, the device is extremely familiar to 8051 users but provides the speed of a 16-bit processor.
