UNIVERSAL PROGRAMMABLE PERIPHERAL
INTERFACE - 8-BIT MICROCOMPUTER
DESC RIPTiON
FEATURES
The IlPD8041 A/8741 A is a programmable peripheral interface intended for use
in a wide range of microprocessor systems. Functioning as a totally self-sufficient
controller, the IlPD8041A/8741A contains an 8-bit CPU, 1K x 8 program
memory, 64 x 8 data memory, I/O lines, counter/timer, and clock generator in a
40'pin DIP. The bus structure, data registers, and status register enable easy interface
to 8048, 8080A or 8085A based systems. The IlPD8041 A's program memory is fac-
tory mask programmed, while the IlPD8741 A's program memory is UV EPROM to
enable user flexibility.
• Fully Compatible with 8048, 8080A, 8085A and 8086 8us Structure
• 8·8it CPU with 1K x 8 ROM, 64 x 8 RAM, 8·Bit Timer/Counter,
18 I/O Lines
• 8-Bit Status and Two Data Registers for Asynchronous Slave·to-Master
Interface
• Interchangeable EPROM and ROM Versions
• Interrupt, DMA or Polled Operation
• Expandable I/O
• 40·Pin Plastic or Ceramic Dip
• Single +5V Supply
