The IntelG!! S04SH/S04SH-1/S035HL/S035HL-1 are totally self-sufficient, 8-bit parallel computers fabricated on single silicon chips using Intel'sadvanced N-channel silicon gate HMOS process.

The S04SH contains a 1K X S program memory, a 64 X S RAM data memory, 27 I/O lines, and an S-bit timer/counter in addition to on-board oscillator and clock circuits. For systems that require extra capability the S04SH can be expanded using standard memories and MCS-SO™/MCS-85'''peripherals. The S035HL is the equivalent of the S04SH without program memory and can be used with external ROM AND RAM.

To reduce development problems to a minimum and provide maximum flexibility, a logically and functionally pin compatible version of the S04SH with UV-erasable user-programmable EPROM program memory is avail- able. The S74S will emulate the S04SH up to 6 MHz clock frequency with minor differences.

The S04SH is fully compatible with the S04S when operated at 6 MHz.

These microcomputers are designed to be efficient controllers as well as arithmetic processors. They have extensive bit handling capability as well as facilities for both binary and BCD arithmetic. Efficient use of progra'mmemory results from an instruction set consisting mostly of single bit instructions and no in-

structions over 2 bytes in length.				.
