Functional Description
The CY7C1351 is a 3.3V, 128K by 36 Synchronous Flow-Through Burst
SRAM designed specifically to support unlimited true back-to-back
Read/Write operations without the insertion of wait states. The
CY7C1351 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.
The CY7C1351 is pin/functionally compatible to ZBT SRAMs IDT71V547,
MT55L128L36F, and MCM63Z737.
Features
• Pin compatible and functionally equivalent to ZBT™ devices
IDT71V547, MT55L128L36F, and MCM63Z737
• Supports 66-MHz bus operations with zero wait states
— Data is transferred on every clock
• Internally self-timed output buffer control to eliminate the need
to use OE
• Registered inputs for Flow-Through operation
• Byte Write capability
• 128K x 36 common I/O architecture
• Single 3.3V power supply
• Fast clock-to-output times
— 11.0 ns (for 66-MHz device)
— 12.0 ns (for 50-MHz device)
— 14.0 ns (for 40-MHz device)
• Clock Enable (CEN) pin to suspend operation
• Synchronous self-timed writes
• Asynchronous Output Enable
• JEDEC-standard 100 TQFP package
• Burst Capability—linear or interleaved burst order Low standby
