Description

The 80CL51 is manufactured in an advanced CMOS technology. The instruction set of the 80CL51 is based on that of the 8051.

The 80CL51 is a general purpose microcontroller especially suited for battery-powered applications. The device has low power consumption and a wide range of supply voltage. For emulation purposes, the 85CL000 (Piggy-back version) with 256 bytes of RAM is recommended.

The 80CL51 has two software selectable modes of reduced activity for further power reduction: Idle and Power-down.

The 80CL51 also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities. The instruction set consists of over 100 instructions: 49 one-byte, 46 two-byte, and 16 three-byte. The P80CL31 is the ROMless version of the P80CL51. P80C51 is a 5V version of the low voltage P80CL51. The P80CL31 is the ROMless version of the P80CL51. P80C51 is a 5V version of the low voltage P80CL51.
