UNIVERSAL PERIPHERAL INTERFACE 8Bit SLAVE MICROCONTROLLER
UNIVERSAL PERIPHERAL INTERFACE 8-BIT SLAVE MICROCONTROLLER
The 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.
To allow full user flexibility, the program memory is available in ROM and One-Time Programmable EPROM OTP. All UPI-41AH and UPI-42AH devices are fully pin compatible for easy transition from prototype to production level designs.
