Part Number : 8741AH
Function : UNIVERSAL PERIPHERAL INTERFACE 8-BIT SLAVE MICROCONTROLLER
Manufacturers : Intel
The Intel UPI-41AH and UPI-42AH are general-purpose Universal Peripheral Interfaces that allow the designer to develop customized solutions for peripheral device control.
They are essentially “slave” microcontrollers, or microcontrollers 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.
