The CY7C131-25NXCT: This part is sourced through independent distribution channels.
Dual-port asynchronous SRAM, 8 Kbit, 25 ns
The CY7C131-25NXCT is an 8 Kbit (1K x 8) dual-port asynchronous SRAM with a parallel interface and a 25 ns access time. The 25 ns access time sets the bus timing window for the system architect — the memory can be read or written within a single 40 MHz clock cycle, but the asynchronous handshake must be managed externally.
52-PQFP surface-mount, commercial temperature
Packaged in a 52-BQFP (52-PQFP, 10x10 mm body) for surface-mount assembly. The 0.65 mm pitch demands careful solder-paste stencil design and X-ray inspection for hidden joints under the quad flat pack. Not suitable for extended industrial or automotive temperature ranges without additional thermal management. Supplied in Tape & Reel (TR) packaging, consistent with volume pick-and-place production.
