The Intel 8742 is a general-purpose Universal Peripheral Interface that allows designers to grow their own
customized solution for peripheral device control. It contains a low-cost microcomputer with 2K of program
memory, 128 bytes of data memory, 8-bit timer/counter, and clock generator in a single 40-pin package.
Interface registers are included to enable the UPI device to function as a peripheral controller in the MCS
é
-48,
MCS-51, MCS-80, MCS-85, 8088, 8086 and other 8-, 16-bit systems.
The 8742 is software, pin, and architecturally compatible with the 8741A. The 8742 doubles the on-chip
memory space to allow for additional features and performance to be incorporated in upgraded 8741A de-
signs. For new designs, the additional memory and performance of the 8742 extends the UPI concept to more
complex motor control tasks, 80-column printers and process control applications as examples.
