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.
