CY7C1386B General Description
The Cypress Synchronous Burst SRAM family employs high-speed, low-power CMOS designs using advanced single-layer polysilicon, triple-layer metal technology. Each memory cell consists of six transistors.
The CY7C1386B and CY7C1387B SRAMs integrate 524,288 * 36 and 1,048,576 * 18 SRAM cells with advanced synchronous peripheral circuitry and a 2-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, data inputs, address-pipelining Chip Enables (CEs), burst control inputs (ADSC, ADSP, and ADV), Write Enables (BWa, BWb, BWc, BWd and BWE), and Global Write (GW).
Asynchronous inputs include the Output Enable (OE) and burst mode control (MODE). DQa,b,c,d and DPa,b,c,d apply to CY7C1386B and DQa,b and DPa,b apply to CY7C1387B. a, b, c, and d each are 8 bits wide in the case of DQ and 1 bit wide in the case of DP.
Addresses and chip enables are registered with either Address Status Processor (ADSP) or Address Status Controller (ADSC) input pins. Subsequent burst addresses can be internally generated as controlled by the Burst Advance Pin (ADV).
Address, data inputs, and write controls are registered on-chip to initiate self-timed Write cycles. Write cycles can be one to four bytes wide as controlled by the write control inputs. Individual byte write allows individual byte to be written. BWa controls DQa and DQPa. BWb controls DQb and DQPb. BWc controls DQc and DQPd. BWd controls DQdDQd and DQPd. BWa, BWb, BWc, and BWd can be active only with BWE LOW. GW LOW causes all bytes to be written. Write pass-through capability allows written data available at the output for the immediately next Read cycle. This device also incorporates pipelined enable circuit for easy depth expansion without penalizing system performance.
The CY7C1386B and CY7C1387B are both double-cycle deselect parts. All inputs and outputs of the CY7C1386B and the CY7C1387B are JEDEC-standard JESD8-5-compatible.
