1 / 30 page  CY7C1440KV25 36-Mbit (1M × 36) Pipelined Sync SRAM Cypress Semiconductor Corporation • 198 Champion Court • San Jose , CA 95134-1709 • 408-943-2600 Document Number: 001-94719 Rev. *D Revised June 30, 2016 36-Mbit (1M × 36) Pipelined Sync SRAM Features ■ Supports bus operation up to 250 MHz ■ Available speed grade is 250 MHz ■ Registered inputs and outputs for pipelined operation ■ 2.5-V core power supply ■ 2.5-V I/O power supply ■ Fast clock-to-output times ❐ 2.5 ns (for 250-MHz device) ■ Provide high-performance 3-1-1-1 access rate ■ User-selectable burst counter supporting interleaved or linear burst sequences ■ Separate processor and controller address strobes ■ Synchronous self-timed writes ■ Asynchronous output enable ■ Single-cycle Chip Deselect ■ CY7C1440KV25 available in Pb-free 165-ball FBGA package. ■ IEEE 1149.1 JTAG-Compatible Boundary Scan ■ “ZZ” Sleep Mode Option Functional Description The CY7C1440KV25 SRAM integrates 1M × 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 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 Descriptions and Truth Table for further details). Write cycles can be one, two or four bytes wide as controlled by the byte write control inputs. GW when active LOW causes all bytes to be written. The CY7C1440KV25 operates from a +2.5 V core power supply while all outputs may operate with a +2.5 V supply. All inputs and outputs are JEDEC-standard JESD8-5-compatible.
