Nonvolatile SRAMs expand to 8Mbit
New 2 and 8Mbit nvSRAMs feature access times as low as 20ns, infinite read, write and recall cycles, and 20-year data retention.
Design tool bridges high and low levels
Integrated design environment includes both code-free and high-level-language programming modes in one package.
The family can help eliminate contention and arbitration issues on a shared bus when multiple processors or functional blocks need access to the same data, thereby significantly improving overall system performance.
Cypress pioneered the concept of QuadPort DSEs with the introduction of its 1Mbit family (10Gbit/s bandwidth) in 2001, including functions such as 2 x 2 switching, datapath aggregation, redundant data generat
