Description:	MCS-41 are slave controllers commonly used for keyboard control or other simple tasks such as ADC control. 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 MCSÉ-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 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. 8041 64x8 RAM 2k8 PROM 8042 128x8 RAM 2k-8 PROM 8742 128x8 RAM 2k8 EPROM ----------------------------- This is a Fujitsu 8042 preloaded with EPSON Code.
