Part Number : 8741AH
Function : UNIVERSAL PERIPHERAL INTERFACE 8-BIT SLAVE MICROCONTROLLER
Package : DIP 40 Pin, PLCC 44 Pin Type
Maker : Intel
Pinouts : 
Description :
The Intel UPI-41AH and UPI-42AH, 8741AH 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.
Features
1. UPI-41: 6 MHz; UPI-42: 12.5 MHz
2. Pin, Software and Architecturally Compatible with all UPI-41 and UPI-42 Products
3. 8-Bit CPU plus ROM/OTP EPROM, RAM I/O, Timer/Counter and Clock in a
Single Package
4. 2048 x 8 ROM/OTP, 256 x 8 RAM on UPI-42, 1024 x 8 ROM/OTP, 128 x 8 RAM on UPI-41, 8-Bit Timer/Counter, 18 Programmable I/O Pins
5. One 8-Bit Status and Two Data Registers for Asynchronous Slave-to Master Interface
6. DMA, Interrupt, or Polled Operation Supported
