P80CL31; P80CL51
GENERAL DESCRIPTION
The P80CL31; P80CL51 (hereafter generally referred to as the P80CLx1) is manufactured in an advanced CMOS technology. The P80CLx1 has the same instruction set as the 80C51, consisting of over 100 instructions: 49 one-byte, 46 two-byte, and 16 three-byte. The device operates over a wide range of supply voltages and has low power consumption; there are two software selectable modes for power reduction: Idle and Power-down. For emulation purposes, the P85CL000 (piggy-back version) with 256 bytes of RAM is recommended. This data sheet details the specific properties of the P80CL31; P80CL51. For details of the 80C51 core see "Data Handbook IC20". 2.1 Versions: P80CL31 and P80C51
The P80CL31 is the ROMless version of the P80CL51. The mask options on the P80CL31 are fixed as follows: · All ports have option `1S' (standard, HIGH after reset) · Oscillator option: Oscillator 3 · Power-on-reset option: OFF. The P80C51 is a restricted-voltage range version of the P80CL51. The operating voltage is 5.0 V ±10%.
The P80CLx1 is especially suited for real-time applications such as instrumentation, industrial control, intelligent computer peripherals and consumer products. The P80CLx1 also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities.
