The Infineon CY7C1399B-15ZXC is a 256Kbit asynchronous SRAM organized as 32K x 8 bits, with a 15 ns access time and a parallel interface. It operates from a 3V to 3.6V supply and is rated for 0°C to 70°C.
The 15 ns access time sets the window for valid data after address latch. Write cycle time matches at 15 ns.
We supply the CY7C1399B-15ZXC through our independent distribution network. It is quoted to order against an RFQ — availability and current pricing are confirmed at quote time. No minimum order quantity is stated; volume inquiries are welcome.
No official pin-compatible successor is listed by Infineon. Any replacement would require a board spin or a validated second-source qualification. For legacy repairs, sourcing the exact CY7C1399B-15ZXC through independent channels is the recommended path.
The package is a 28-TSSOP (0.465", 11.80mm Width), surface-mount, supplied in Tray. The supplier device package is 28-TSOP I.
It is an asynchronous SRAM — volatile memory with a parallel interface, organized as 32K x 8 bits.
