CY7C1218F www.DataSheet4U.com 1-Mb (32K x36) Pipelined Sync SRAM Features Registered inputs and outputs for pipelined operation 32K × 36 common I/O architecture 3.3V core power supply 3.3V I/O operation Fast clock-to-output times — 3.5 ns (for 166-MHz device) — 4.0 ns (for 133-MHz device) Provide high-performance 3-1-1-1 access rate User-selectable burst counter supporting Intel Pentium interleaved or linear burst sequences Separate processor and controller address strobes Synchronous self-timed writes Asynchronous output enable Offered in JEDEC-standard 100-pin TQFP package “ZZ” Sleep Mode Option counter for internal burst operation. All synchronous inputs are gated by registers controlled by a positive-edge-triggered Clock Input (CLK). The synchronous inputs include all addresses, all data inputs, address-pipelining Chip Enable (CE1), depth-expansion Chip Enables (CE2 and CE3), Burst Control inputs (ADSC, ADSP, and ADV), Write Enables (BW[A:D], and BWE), and Global Write (GW). Asynchronous inputs include the Output Enable (OE) and the ZZ pin. Addresses and chip enables are registered at rising edge of clock when either Address Strobe Processor (ADSP) or Address Strobe Controller (ADSC) are active. Subsequent burst addresses can be internally generated as controlled by the Advance pin (ADV). Address, data inputs, and write controls are registered on-chip to initiate a self-timed Write cycle.This part supports Byte Write operations (see Pin Descripti...
