Registered inputs and outputs for pipelined operation Optimal for performance (Double-Cycle deselect) — Depth expansion without wait state 32K × 36-bit common I/O architecture 3.3V –5% and +10% core power supply (VDD) 3.3V I/O supply (VDDQ) 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 JEDEC-standard 100-pin TQFP package and pinout “ZZ” Sleep Mode option
Functional Description[1]
The CY7C1219F SRAM integrates 32,768 x 36 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: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 ...
