General Description
The UMS04S/S035/~049/8039 is a totally self-sufficient
8-bit parallel computer fabricated on a single silicon chip
using UMC N-channel silicon gate MOS process.
The UMS048 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. The
UMS049 contains a 2K x S program memory, a 128 x S
RAM data memory, 27 I/O lines, and an S-bit timer/counter
in qddition to on board oscillator and clock circuits. For
systems· that requ ire extra capabi Iity, the UMS04S/8049
can be expanded using standard memories and MCS-4S,
• UMS04S/8049 is interchangeable with Intel's PS04S/
S049 in pin configuration and electrical characteristics
• UMS049-2Kx8 ROM 12Sx8 RAM 27 I/O Lines
UMS04S-1KxS ROM 64xB RAM 27 I/O Lines
• Internal timer/event counter
• Easily expandable memory and I/O
• Compatible with MCS memory and I/O
MCS-80 and MCS-85 peripherais. The UMS035 is the
equivalent of an UMS04S without program memory. The
UMS039 is the equivalent to an UM8049 without program
memory.
This microprocessor is designed to be an efficient controller
as well as an arithmetic processor. The UMS04S/S049 has
extensive bit handling capability as well as facilities for
both binary and BCD arithmetic. Efficient use of program
memory results from an instruction set consisting mostly of
single byte instructions and non instructions over two
bytes in length.
