CY7C1386S

CY7C1386S 18-Mbit (512 K × 36) Pipelined DCD Sync SRAM 18-Mbit (512 K × 36) Pipelined DCD Sync SRAM Features ■ Supports bus operation up to 167 MHz ■ Available speed grade is 167 MHz ■ Registered inputs and outputs for pipelined operation ■ Optimal for performance (double-cycle deselect) ■ Depth expansion without wait state ■ 3.3 V core power supply (VDD) ■ 2.5 V or 3.3 V I/O power supply (VDDQ) ■ Fast clock-to-output times ❐ 3.4 ns (for 167 MHz device) ■ Provides 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 ■ Available in JEDEC-standard Pb-free 100-pin TQFP ■ ZZ sleep mode option Functional Description The CY7C1386S SRAM integrates 512 K × 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 (BWX, 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 addres...
