The MCS 51 CHMOS microcontroller products are fabricated on Intel’s reliable CHMOS process and are

functionally compatible with the standard MCS 51 HMOS microcontroller products This technology combines

the high speed and density characteristics of HMOS with the low power attributes of CHMOS This combina-

tion expands the effectiveness of the powerful MCS 51 microcontroller architecture and instruction set

Like the MCS 51 HMOS microcontroller versions the MCS 51 CHMOS microcontroller products have the

following features 4 Kbytes of EPROM ROM (87C51 80C51BH respectively) 128 bytes of RAM 32 I O lines

two 16-bit timer counters a five-source two-level interrupt structure a full duplex serial port and on-chip

oscillator and clock circuitry In addition the MCS 51 CHMOS microcontroller products exhibit low operating

power along with two software selectable modes of reduced activity for further power reduction Idle and

Power Down

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

The 87C51 is the EPROM version of the 80C51BH It contains 4 Kbytes of on-chip program memory that can

be electrically programmed and can be erased by exposure to ultraviolet light The 87C51 EPROM array uses

a modified Quick-Pulse Programming algorithm by which the entire 4 Kbyte array can be programmed in about

12 seconds
