2 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%.
3 APPLICATIONS
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.
