DESCRIPTION The DS80C320/DS80C323 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
DS80C320 offers a maximum crystal rate of 33 MHz, resulting in apparent execution speeds of 82.5 MHz
(approximately 2.5X).
The DS80C320/DS80C323 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.
The DS80C320 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.
The DS80C320 operating voltage ranges from 4.25V to 5.5V, making it ideal as a high-performance upgrade to existing 5V systems. For applications in which power consumption is critical, the DS80C323
offers the same feature set as the DS80C320, but with 2.7V to 5.5V operation.

80C32 COMPATIBILITY The DS80C320/DS80C323 is a CMOS 80C32-compatible microcontroller designed for high
performance. In most cases it will drop into an existing 80C32 design to significantly improve the operation. Every effort has been made to keep the device familiar to 8032 users, yet it has many new
features. In general, software written for existing 80C32-based systems will work on the
DS80C320/DS80C323. The exception is critical timing since the High-Speed Microcontroller performs its instructions much faster than the original. It may be necessary to use memories with faster access
times if the same crystal frequency is used.
Application note 57 “DS80C320 Memory Interface Timing” is a useful tool to help the embedded system
designer select the proper memories for her or his application.
The DS80C320/DS80C323 runs the standard 8051 instruction set and is pin-compatible with an 80C32 in
