PACE1754/SOS

PROCESSOR INTERFACE CIRCUIT (PIC)

CMOS/SOS SPACE PROCESSOR

MICROPERIPHERAL

FEATURES

Single 5V ± 10% Power Supply

The PACE1754 (PIC) is a support chip for the

PACE1750A/AEProcessors. Iteliminatesthe

SSI/MSI Logic and external system functions

required in typical 1750A implementations.

Available in:

— 68-Lead Quad Pack with optional Gull Wing

Surface Mount

Provides a significant savings in part-count and

power dissipation enhancing reliability and

overall system speed performance.

Provides an optimal interface when used with

the PACE1753 MMU/COMBO in a full 1750A

implementation.

Provides the following additional important

system functions:

— Programmable READY for memory and I/O

— Automatic READY during self-test and

internal I/O instructions

— 100KHz timer clock output provided

— Programmable system watchdog—ranges

from 1 µs to 1 minute

— Programmable Bus time-out function

— Memory Parity generation/detection

— Error detection of unimplemented memory

and/or I/O space addressing

— First failing memory address register for

diagnostics

— High drive three-state address latches

— Built-in system test program—automatically

address lines as well as memory and I/O

strobes

— System configuration decoding and buffering

— Interrupt acknowledge decoder and strobe

— Start up ROM support per MIL-STD-1750A

— Memory or I/O READ/WRITE three-state

strobes with external three-state control for

DMA applications
