PACE1753/SOS

SINGLE CHIP, MIL-STD-1750A

MEMORY MANAGEMENT UNIT (MMU)

CMOS/SOS SPACE PROCESSOR MICROPERIPHERAL

FEATURES

8-bit extended address laches and drivers on

chip.

Implements the MIL-STD-1750A Instruction Set

Architecture for Memory Management and

Protection of up to 1 Megaword. All mapping

memory (10,240 bits) for both the MMU and

BPU functions are included on the chip.

20, 25 and 30 MHz operation over the Military

Temperature Range

Single 5V ± 10% Power Supply

Designed to interface memory to the

PACE1750A/AE.

Available with Class S manufacturing,

screening, and testing.

Provides the following additional functions:

SOS Insulated substrate latch-up immunity and

excellent SEU tolerance.

— EDAC, Error Detection and Correction—or

parity generation and detection

— Correct data register—for diagnostics

— First memory failing address register

— Illegal address error detection—

programmable

SOS devices are fully interchangeable with

application-proven SMD CMOS P1753 devices.

Available in:

— 68-Lead Quad Pack (Leaded Chip Carrier)

with optional Gull Wing.

— Multi-Master arbitration

MEMORY MANAGEMENT UNIT AND

BLOCK PROTECT UNIT “COMBO”

(PACE1753)—FUNCTIONAL DESCRIPTION

The PACE1753 (COMBO) is a support chip for the

PACE1750A/AE microprocessor family. It provides the

following supporting functions to the system:

1. Memory management and access protection for up

to 1M words.

Physical memory write protection for up to 1M words

memory in pages of 1K words each. Separate

protection is provided for the CPU and for DMA in

systems which include DMA.

3. Detection of illegal l/O accesses (as defined by MIL-

STD-1750A) or access to an unimplemented block

of memory. In each case an error flag is generated

to the processor.

Detection of double errors on the data bus and

correctionofsingleerrors. Anerrorsignalisgenerated

to the processor when a multiple error is detected.

5. RDYA generation. Up to three wait states can be

insertedintheaddressphaseofthebusbygenerating

a not-ready, RDYA low signal. The number of wait

states required can be programmed in an internal

6. Bus arbitration for up to 4 masters. Arbitration is

done on a fixed priority basis (i.e. by interconnection

of hardware). (In 68 pin package only).
