CY7C1350-133AC

Functional Description

The CY7C1350 is a 3.3V 128K by 36 synchronous-pipelined Burst SRAM designed specifically to support unlimited true back-to-back Read/Write operations without the insertion of wait states. The CY7C1350 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 the SRAM, especially in systems that require frequent Write/Read transitions. The CY7C1350 is pin/functionally compatible to ZBT SRAMs IDT71V546, MT55L128L36P and MCM63Z736.

Features

• Pin compatible and functionally equivalent to ZBT devices IDT71V546, MT55L128L36P and MCM63Z736
• Supports 143-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
• Fully registered (inputs and outputs) for pipelined operation
• Byte Write capability
• 128K x 36 common I/O architecture
• Single 3.3V power supply
• Fast Clock-to-output times
— 4.0 ns (for 143-MHz device)
— 4.2 ns (for 133-MHz device)
— 5.0 ns (for 100-MHz device)
— 7.0 ns (for 80-MHz device)
• Clock Enable (CEN) pin to suspend operation
• Synchronous self-timed writes
• Asynchronous output enable
• JEDEC-standard 100 TQFP package
