– stack depth limited only by available internal RAM

(maximum 256 bytes)

– multiply, divide, subtract and compare instructions

• Reduced power consumption through Power-down and

Idle modes

• Wake-up via external interrupts at Port 1

• Frequency range: 0 to 12 MHz. For ADC operation

minimum 250 kHz at 2.7 V

• Supply voltage: 2.5 to 6.0 V

• Very low current consumption:

typically 4.5 mA at 2.5 V and 8 MHz

• Operating ambient temperature range: −40 to +85 °C.

GENERAL DESCRIPTION

The P80CL580; P83CL580 (hereafter generally referred to

as P8xCL580) is manufactured in an advanced CMOS

technology. The P8xCL580 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 P85CL580 (piggy-back

version) with 256 bytes of RAM is recommended.

This data sheet details the specific properties of the

P80CL580; P83CL580. For details of the 80C51 core and

the I2C-bus see

“Data Handbook IC20”.

2.1

ROMless version: P80CL580

The P80CL580 is the ROMless version of the P83CL580.

The mask options on the P80CL580 are fixed as follows:

• All ports have option ‘1S’ (standard port, HIGH after

reset), except ports P1.6 and P1.7 which have option

‘2S’ (open-drain, HIGH after reset)

• Oscillator option: Oscillator 3

• Power-on-reset option: off.

APPLICATIONS

The P8xCL580 is an 8-bit general purpose microcontroller

especially suited for cordless telephone and mobile

communication applications. The P8xCL580 also

functions as an arithmetic processor having facilities for

both binary and BCD arithmetic plus bit-handling

capabilities.
