MEMORY ORGANIZATION
PROGRAM MEMORY Up to 4 Kbytes of the program memory can reside on-chip (except 80C31BH) In
addition the device can address up to 64K of program memory external to the chip
DATA MEMORY This microcontroller has a 128 x 8 on-chip RAM In addition it can address up to 64 Kbytes of
external data memory
The Intel 87C51 80C51BH 80C31BH is a single-chip control-oriented microcontroller which is fabricated on
Intel’s reliable CHMOS III-E technology Being a member of the MCS 51 controller family the
87C51 80C51BH 80C31BH uses the same powerful instruction set has the same architecture and is pin-for-
pin compatible with the existing MCS 51 controller family of products
The 80C51BHP is identical to the 80C51BH When ordering the 80C51BHP customers must submit the 64
byte encryption table together with the ROM code Lock bit 1 will be set to enable the internal ROM code
protection and at the same time allows code verification
The extremely low operating power along with the two reduced power modes Idle and Power Down make
this part very suitable for low power applications The Idle mode freezes the CPU while allowing the RAM
timer counters serial port and interrupt system to continue functioning The Power Down mode saves the
RAM contents but freezes the oscillator causing all other chip functions to be inoperative
For the remainder of this document the 87C51 80C51BH and 80C31BH will be referred to as the 87C51 BH
