typically 4.5 mA at 2.5 V and 8 MHz
• Operating ambient temperature range: −40 to +85 °C.
2 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.
3 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.
