12 ns access time and write cycle time. Asynchronous device; timing set by address-to-data path, not a clock edge.
The 28-SOJ package is a common footprint for 256Kbit SRAMs — 0.300-inch body width, 7.62 mm, with J-bend leads for surface mounting. The SOJ footprint is compatible with many legacy board layouts; verify the land pattern against your existing design before committing the BOM.
The closest pin-compatible alternative is another member of the CY7C199 family with the same 32K x 8 organization and 28-SOJ package, such as the CY7C199-15VXI or CY7C199-20VXI. Verify the access time meets your timing requirements, as these parts have slower 15 ns or 20 ns ratings.
The CY7C199CN-12VXI is supplied in a tube and packaged in a 28-BSOJ (0.300", 7.62mm Width) surface-mount package, with the supplier device package designated as 28-SOJ.
The CY7C199CN-12VXI is an asynchronous SRAM with volatile memory type and a parallel memory interface.
