Product details

256Kbit asynchronous SRAM — 12 ns access, 32K×8, 3.3 V

The CY7C1399BN-12VXCT is a 256Kbit asynchronous SRAM organized as 32K words by 8 bits. It delivers a 12 ns access time from a 3 V to 3.6 V supply.

12 ns access time — what it means for the bus

The 12 ns access time sets the window from address valid to data valid on a read cycle. The 12 ns write cycle time is symmetrical.

Obsolete — sourcing reality

This part is marked obsolete by Cypress (Infineon). We source it against an RFQ from our independent distribution network.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1399BN-12VXCT?

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.

What package does CY7C1399BN-12VXCT come in?

It is supplied in a 28-SOJ wide-body (0.300", 7.62 mm width) surface-mount package, on Tape & Reel.
