The Intel 8741A is a general purpose, programmable interface device designed for use with a variety of 8-bit microprocessor systems. It contains a low cost microcomputer with program memory, data memory,8-bit CPU, I/O ports, timer/counter, and clock in a single 40-pin package. Interface registers are included to enable the UPI device to function as a peripheral controller in MCS -48, MCS-80, MCS-85, MCS-86, and other 8-bit systems.
The UPI-41A has 1K words of program memory and 64 words of data memory on-chip.
The device has two 8-bit, TTL compatible l/O ports and two test inputs. Individual port lines can function as either inputs or outputs under software control.I/O can be expanded with the 8243 device which is directly compatible and has 16 l/O lines. An 8-bit programmable timer/counter is included in the UPI device for generating timing sequences or counting external inputs. Additional UPI features include: single 5V supply, single-step mode for debug and dual working register banks.
Because it's a complete microcomputer, the UPI provides more flexibility for the designer than conventional LSI interface devices. It is designed to be an efficient controller as well as an arithmetic processor. Applications include keyboard scanning, printer control, display multiplexing and similar functions which involve interfacing peripheral devices to microprocessor systems.
