The D8749H/D8748H are self-sufficient, 8-bit parallel computers fabricated on single silicon chips using Intel’s advanced N-channel silicon gate HMOS-E process.
The family contains 27 I/O lines, an 8-bit timer/counter, on-chip RAM, and on-board oscillator/clock circuits. For systems that require extra capability, the family can be expanded using MCS®.80/MCS®-85 peripherals,
These microcomputers are designed to be efficient controllers as well as arithmetic processors. They have extensive bit-handling capability as well as facies for both binary and BCD arithmetic. Efficient usage of program memory results from an instruction set consisting mostly of single-byte instructions and no instructions over 2 bytes in length
