DETAILED DESCRIPTION
The DS80C320/DS80C323 are 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 DS80C320
offers a maximum crystal rate of 33MHz, resulting in apparent execution speeds of 82.5MHz
(approximately 2.5X).
The DS80C320/DS80C323 are 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 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.
