Pyramid Semiconductor offers the following products in the MIL-STD-1750A family:
- A complete family of MIL-STD-1750A products in CMOS which execute the MIL-STD-1750A Instruction Set Architecture (ISA). 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. All of these products are in production at Pyramid Semiconductor and are being used in a myriad of Military applications. Application proven P1750A and P1750AE 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. These devices are offered to Standard Military Drawings.
- The P1750A CPU, P1753 MMU, and P1754 PIC products are also offered on Silicon On Sapphire SOS technology. These Radiation Hardened devices are used in launch vehicles and long term satellite applications where Total Dose tolerance and Single Event Upset protection is required.

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. 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.
Pyramid Semiconductor is continuing to manufacture and deliver all the products in the P1750A family of MIL-STD-1750A Processors. This family includes:
- In CMOS technology: the P1750A, P1750AE, P1753, P1754, and P1757ME for military avionics, guidance control and airborne applications.
- In CMOS/SOS technology: the P1750A/SOS, P1750AE/SOS, P1753/SOS and P1754/SOS for Launch Vehicles and long term Satellite applications.
All of the above products are offered in various speed, temperature ranges, packages, and test/screening flows.
Pyramid Semiconductor continues to be the leading supplier of fast, application proven microprocessors for all types of MIL-STD-1750A requirements. 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. Pyramid Semiconductor's PACE P1750A Product line consists of two single-chip MIL-STD-1750A stand-alone microprocessors, P1750A & P1750AE, and the two microperipheral devices which provide the support functions required for a complete MIL-STD-1750A Processor. 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.
Customers presently using the P1750A in their system can easily upgrade their boards by simply replacing the P1750A with the P1750AE and obtain 40% higher throughput at the same clock frequency without the need to redesign the board. 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. Additionally, this 40% improvement in performance is obtained without the need to use faster external SRAMs.
The P1750A Processor product line includes a family of Processor devices built in CMOS for Avionics, Missile Guidance and Airborne applications. The family also includes Processor devices built on Silicon on Sapphire (SOS) technology which 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.
