Product Summary

The DS80C320MNL+ is a High-Speed/Low-Power Microcontroller. The DS80C320MNL+ is fast 80C31/80C32-compatible microcontrollers. 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 see a speed improvement of 2.5 times using the same code and same crystal. The DS80C320MNL+ offers a maximum crystal rate of 33MHz, resulting in apparent execution speeds of 82.5MHz (approximately 2.5X). The DS80C320MNL+ is pin compatible with all three packages of the standard 80C32 and offer the same timer/counters, serial port, and I/O ports. In short, the devices are extremely familiar to 8051 users, but provide the speed of a 16-bit processor. The DS80C320MNL+ provides several extras in addition to greater speed. These include a second full hardware serial port, seven additional interrupts, programmable watchdog timer, power-fail interrupt and reset. The device also provides dual data pointers (DPTRs) to speed block data memory moves. It can also adjust the speed of off-chip data memory access to between two and nine machine cycles for flexibility in selecting memory and peripherals.
