The UPI-C42 is an enhanced CHMOS version of the industry standard Intel UPI-42 family. It is fabricated on
Intel’s CHMOS III-E process. The UPI-C42 is pin, software, and architecturally compatible with the NMOS UPI
family. The UPI-C42 has all of the same features of the NMOS family plus a larger user programmable memory
array (4K), hardware A20 gate support, and lower power consumption inherent to a CHMOS product.
The UPI-L42 offers the same functionality and socket compatibility as the UPI-C42 as well as providing low
voltage 3.3V operation.
The UPI-C42 is essentially a ‘‘slave’’ microcontroller, or a microcontroller with a slave interface included on the
chip. Interface registers are included to enable the UPI device to function as a slave peripheral controller in the
MCS Modules and iAPX family, as well as other 8-, 16-, and 32-bit systems.
To allow full user flexibility, the program memory is available in ROM and One-Time Programmable EPROM
(OTP).
