The UPI-C42 is an enhanced CHMOS version of the industry standard Intel UPI-42 family It is fabricated on
Intel鈥檚 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 鈥樷€榮lave鈥欌€?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)
