MICROPROCESSORS MIL-STD-1750A

Pyramid Semiconductor Corporation is continuing to manufacture and deliver all the products in the P1750A family of fast, application proven MIL-STD-1750A Processors. Pyramid Semiconductor is sole source and committed to long term supply for these Legacy Products.
We offer a complete family of MIL-STD-1750A products in CMOS which execute the MIL-STD-1750A Instruction Set Architecture (ISA).
All of the MIL-STD-1750A Processors products are offered in various speed, temperature ranges, packages, and test/screening flows.
These devices are offered to Standard Military Drawings.
All of these products are today in production at Pyramid Semiconductor Corporation and are being used in a myriad of Military applications.

Products Family

The family includes the P1750A CPU, the P1750AE Enhanced CPU, the P1753 Memory Management Unit (MMU) and the P1754 Processor Interface Chip (PIC) as well as the P1757ME Multi chip Module.

P1750A – SINGLE CHIP PROCESSOR

Application proven P1750A processors operating at 15, 20, 30, and 40 MHz are being used to enhance the throughput of systems which utilize the immense inventory of qualified software for MIL-STD-1750A.

P1750AE - ENHANCED SINGLE CHIP CPU

Application proven P1750AE processors operating at 15, 20, 30, and 40 MHz are being used to replace P1750A processors in existing systems and obtain 40% higher throughput at the same clock frequency without the need to redesign the board. Additionally, this 40% improvement in performance is obtained without the need to use faster external SRAMs.
For systems requiring upgrades in performance, a move from the P1750A to the P1750AE is a logical choice since the P1750AE is offered in the same packages as the P1750A. The P1750AE is socket compatible with the P1750A. The same P1753 MMU and P1754 PIC can be used without any modifications to the hardware implementation.

P1753 - MEMORY MANAGEMENT UNIT (MMU)

P1754 - PROCESSOR INTERFACE CHIP (PIC)

P1757ME – MULTI CHIP PROCESSOR MODULE USING THE P1750AE, P1753 AND P1754

The P1757ME is a multichip 144 Pin device that contains the P1750AE Microprocessor, P1753 MMU, and the P1754 Processor Interface. With the P1757ME, the designer of embedded systems need only add memory and appropriate IO to complete the system. The P1757ME is an excellent solution for a performance increasing hardware upgrade that will extend the life of an investment in qualified, application proven software. The P1757ME has been application proven aboard submarines, aircraft, and satellites

AVAILABLE IN PRODUCTION MIL-STD-1750A PROCESSORS

Applications

MIL-STD-1750A applications continue to evolve as system designs utilize the existing, huge inventory of application proven software to provide enhanced system capability at low cost, low risk, and with short development cycles.
Flight tested hardware upgrades using Pyramid Semiconductor's P1750AE Processor report a 40% higher throughput to the DAIS mix and in some applications, the performance upgrade may be improved as much as 2.5x without memory or clock frequency upgrade.
All of Pyramid Semiconductor's MIL-STD-1750A processors, microperipherals, and multichip modules are application proven in high performance critical systems such as EW, guidance, and flight control.
These systems, using the P1750A/AE Processor, are aboard submarines, surface platforms, aircraft, cruise missiles, launch vehicles, and spacecraft.
The P1750A Processor product line includes a family of Processor devices built in CMOS for Avionics, Missile Guidance and Airborne applications.
The Processor devices built on Silicon on Sapphire (SOS) technology are tolerant to Single Event Upsets (SEU) as well as Total Dose Radiation tolerance of greater than 100K Total Dose. The SOS devices are designed for Launch Vehicles and long term Satellite applications.
