M8751H-8
Single-Component 8-Bit Microcomputer
The M8751H-8 is a pin compatible EPROM version of M8051AH. Intel’s advanced +5V, depletion
load, N-channel, HMOS technology allows the M8751H-8 to remain fully compatible with its
M8751H-8 predecessor in addition to incorporating two new features: A program memory security
bit that can be used to protect the EPROM against unauthorized readout, and a programmable baud
rate modification bit, which doubles the range of baud rates available to the serial port.
Specifically, the M8751H-8 features: 4K byte program memory space; 32 I/O lines; two 16-bit
timer/event counters; a 5-source, 2-level interrupt structure; a full duplex serial channel; a Boolean
processor; and on-chip oscillator and clock circuitry. Standard TTL and most byte-oriented MCS-80
and MCS-85 peripherals can be used for I/O and memory expansion.
