CY7C1355B Overview
[1] The CY7C1355B/CY7C1357B is a 3.3V, 256K x 36/ 512K 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 CY7C1355B/CY7C1357B 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.
CY7C1355B Key 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 patible 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)
