The CY7C1399BN-12VXCT is a 256Kbit asynchronous SRAM organized as 32K words by 8 bits.
The 12 ns write cycle time is symmetrical.
This part is marked obsolete by Cypress (Infineon). We source it against an RFQ from our independent distribution network.
Active 256Kbit asynchronous SRAMs from Alliance Memory (AS7C256A-12TIN) or ISSI (IS61LV256-12TI) are pin-compatible in the 28-SOJ footprint, operate at 3.3 V, and offer 12 ns access time. They are direct drop-in replacements for new designs or BOM updates.
It is supplied in a 28-SOJ wide-body (0.300", 7.62 mm width) surface-mount package, on Tape & Reel.
