The Company

Pyramid Semiconductor Corporation is a manufacturer of semiconductor integrated circuits including MIL-STD-1750A Processors, Static RAMs, EEPROMs and FCT/FCT-T Logic.

Pyramid Semiconductor Corporation is a fabless semiconductor manufacturer where wafers are manufactured in the USA and TAIWAN at outside wafer foundries. Based on our proprietary high performance semiconductor designs, our devices are offered in a variety of different plastic and hermetic ceramic packages.

Pyramid Semiconductor supports SMD with more than 100 Standard Military drawings (SMDs) available and recommended for high longevity military applications.

The Company occupies a 10,000 square foot facility where die design, wafer testing, assembly of products, environmental testing, electrical testing, burn-in, marking and QA on devices are all performed prior to delivery of products worldwide to various Military, Industrial and Commercial customers. It also gives us the capability to develop custom solutions on demand (logic functions, packages, …) with short lead times.

Headquartered in Sunnyvale, California, USA, the Company was formed in January 2003 through the acquisition of all the product lines from Performance Semiconductor. All products previously supported by Performance Semiconductor are being supported by Pyramid Semiconductor. The Pyramid Semiconductor part numbering scheme is identical to the part numbers previously used by Performance Semiconductor.
On March 8, 2021, HEICO Corporation Electronic Technologies Group acquired Pyramid Semiconductor LLC. The business continues to operate as a part of HEICO/3D PLUS USA, which is also located in the Silicon Valley area. Together, leveraging on their area of expertise, the two businesses will seek to provide customers additional products and capabilities.

The products


We offer 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.
Pyramid Semiconductor Corporation is sole source and committed to long term supply for these Legacy Products. The MIL-STD-1750A Processors are field-proven and have been used reliably by Military users for more than 20 years.


Our High Speed and Low Power SRAMs are designed for the Commercial, Industrial and Military markets. The Product Line includes small and medium density SRAMs from 1K to 4 Mb in Commercial, Industrial, “Mil Temp Only” and MIL-STD-883 compliant. Devices are offered in a number of different plastic and hermetic ceramic packages.


Designed to ensure the data retention and the secure and safe boot of your systems, our product line includes small and medium density EEPROMs with 8Kx8, 32Kx8 and 128Kx8 Organizations. MIL-STD-883 compliant. devices are offered in hermetic ceramic packages to maintain the longevity of your legacy military embedded systems.


We offer a complete High Speed and Low Power Logic Product Line which includes military DLA approved FCT and FCT-T logic devices. The product line consists of 45 functions including octal line drivers, octal bi-directional bus transceivers and latches that are used on every embedded system boards.

Quality Commitment

Pyramid Semiconductor sees Quality as a key factor in the development of our business and as the foundation of trust shown by our customers for more than 18 years.

Pyramid Semiconductor Corporation is certified as an ISO 9001:2015 and AS9100:2016 Supplier and has been granted by DLA (Defense Logistics Agency) with Level Q Certification, MIL-PRF-38535, FSC 5962 (QML) as well as Laboratory Suitability Certification for MIL-STD-883.

From design to manufacturing and test, we are strongly committed in delivering the highest possible quality for our products. Equipment is calibrated on a rigorous schedule, operators are trained on a regular basis, ESD (Electrostatic Discharge) handling procedures are used throughout the facility. Travelers are issued with every lot through the complete manufacturing cycle to provide complete traceability. Diligence is maintained in reviewing customer requirements and compliance to customer drawings and specifications. Quality permeates throughout the organization.

QML Certified Manufacturing Facilities

In approximately 10,000 sq. feet, Pyramid Semiconductor has a complete fabless semiconductor manufacturing facility. The facility includes design, test (wafers and assembled products), a complete clean room assembly facility for ceramic packages, burn-in, marking, environmental test equipment, quality inspection as well as all the additional manufacturing facilities necessary to assemble, test and manufacture complete semiconductor devices. Pyramid Semiconductor uses outside wafer foundries (On Semi, USA and TSMC, Taiwan) to fabricate its wafers. Relationships with the foundries have been established over many years, and the supply of wafers has been ongoing.
This state-of-the-art, independent, reliable and secure supply chain is key to guaranty availability of our parts for the long term.
The Pyramid Semiconductor QML Assembly facility is a Class 1000 --- standards capable of assembly of Class B and Class S devices required for Military and Space applications. Plastic assembly of Pyramid Semiconductor products is performed with sub-contractors in the Far East.
The Pyramid Semiconductor Cage Code is 3DTT2.
