Functional Description[1]

The CY7C1371D/CY7C1373D is a 3.3V, 512K x 36/1 Mbit x 18 Synchronous Flow-through Burst SRAM designed specifically to support unlimited true back-to-back Read/Write operations without the insertion of wait states. The CY7C1371D/ CY7C1373D is equipped with the advanced No Bus Latency (NoBL) logic required to enable consecutive Read/Write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of data through the SRAM, especially in systems that require frequent Write-Read transitions.

特性 Features

• No Bus Latency™ (NoBL™) architecture eliminates dead cycles between write and read cycles

• Can support up to 133-MHz bus operations with zero wait states

— Data is transferred on every clock

• Pin-compatible and functionally equivalent to ZBT™ devices

• Internally self-timed output buffer control to eliminate the need to use OE

• Registered inputs for flow-through operation

• Byte Write capability

• 3.3V/2.5V I/O power supply

• Fast clock-to-output times

— 6.5 ns (for 133-MHz device)

— 8.5 ns (for 100-MHz device)

• Clock Enable (CEN) pin to enable clock and suspend operation

• Synchronous self-timed writes

• Asynchronous Output Enable

• Offered in JEDEC-standard lead-free 100 TQFP, 119-ball BGA and 165-ball fBGA packages

• Three chip enables for simple depth expansion

• Automatic Power-down feature available using ZZ mode or CE deselect

• JTAG boundary scan for BGA and fBGA packages

• Burst Capability—linear or interleaved burst order

• Low standby power
