CY7C1212F www.DataSheet4U.com 1-Mbit (64K x 18) Pipelined Sync SRAM Features Registered inputs and outputs for pipelined operation 64K × 18 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 Functional Description[1] The CY7C1212F SRAM integrates 65,536 x 18 SRAM cells with advanced synchronous peripheral circuitry and a two-bit 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:B], 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 i...
