Cypress CY7C1327F 4-Mb (256K x 18) Pipelined Sync SRAM Datasheet
The CY7C1327F is a 4‑Mb (256K × 18) pipelined synchronous SRAM that operates from a +3.3 V core supply and supports both 3.3 V and 2.5 V I/O levels. It offers registered inputs and outputs for pipelined operation, fast clock‑to‑output times as low as 2.6 ns, and a selectable burst counter for Intel Pentium interleaved or linear burst sequences.
The device is offered in JEDEC‑standard 100‑pin TQFP and 119‑ball BGA packages. Detailed pin definitions, electrical characteristics, maximum ratings, and timing tables are provided to aid designers in integrating the SRAM into high‑performance systems.
