The 72-Mbit QDR-II+ SRAMs deliver industry-leading throughput performance up to 36 gigabits per second (Gbps) by leveraging the ability to read and write data simultaneously. This throughput, combined with complete random access of data and free memory controllers for FPGAs, enables reconfigurable computing platforms that allow satellites to be reprogrammed while in space. The devices also feature the industry's lowest latency and are ideal for radar and networking applications used in space
Both new SRAM families employ Cypress's patented RadStop technology, which enables uncompromised functionality in the face of radiation up to 300 krads. The devices are manufactured in the Cypress's fabrication facility in Bloomington, Minnesota, which is Microelectronics Trusted Category 1A accredited.
"Cypress's radiation-hardened SRAMs demonstrate our commitment to providing QML Class V reliability and superior performance for the aerospace market," said Sam Geha, vice president of the Aerospace and Defense Business Unit at Cypress. "The unmatched throughput of our flagship 72-Mbit QDR-II+ devices enables innovative usages, such as reconfigurable computing, while our 4-Mbit fast asynchronous devices deliver faster speed than any competing solutions."
The radiation-hardened 4-Mbit devices deliver access times of 10 ns at 85 degrees C and 12 ns at 125 degrees C. They are also the first 90-nm, QML-V qualified devices of their kind and are ideal for a wide range of space and military applications.
Cypress's RadStop technology combines manufacturing process hardening and proprietary design techniques. With RadStop technology, the SRAMs deliver single event latch-up immunity and single event functional interrupt immunity at temperatures as high as 125 degrees C.

The Rad-Hard 72-Mbit QDR-II+ SRAMs are available in a 165 column grid array (CGA) package. The devices come in the following four part numbers and configurations with equivalent Defense Supply Center Columbus (DSCC) part numbers:
- CYRS1542AV18-250GCMB (x18 bus width, burst of 2); Class V part number: 5962F1120101VXA
- CYRS1543AV18-250GCMB (x18 bus width, burst of 4); Class V part number: 5962F1120102VXA
- CYRS1544AV18-250GCMB (x36 bus width, burst of 2); Class V part number: 5962F1120201VXA
- CYRS1545AV18-250GCMB (x36 bus width, burst of 4); Class V part number: 5962F1120202VXA
The CYRS1049DV33-12FZMB (5962F1123501VXA) 4-Mbit fast asynchronous SRAMs are available in a 36-pin ceramic flat package.
Designers can also begin prototyping today with ITAR-free CYPTxx products, which are similar in form, fit and function to the flight units. To order, go to www.cypress.com/aero.
