8742

Universal Peripheral Interface 8-Bit Slave Microcontroller

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-48, 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 designs. 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.
