CY7C147-45DC - Brand New Cypress Semiconductor IC Chips
-
Description
The CY7C147-45DC is a 3.3 V, 2 M × 36 synchronous flow through burst SRAM designed specifically to support unlimited true back-to-back read or write operations without the insertion of wait states. It is equipped with the advanced No Bus Latency (NoBL) logic required to enable consecutive read or 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.
Specifications and features
■ No Bus Latency™ (NoBL™) architecture eliminates dead cycles between write and read cycles
■ Supports 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
■ 3.3 V/2.5 V I/O supply (VDDQ)
■ Fast clock-to-output times: 6.5 ns (for 133-MHz device)
■ Clock enable (CEN) pin to enable clock and suspend operation
■ Synchronous self-timed writes
■ Asynchronous output enable (OE)
■ CY7C1471V33 available in JEDEC-standard Pb-free 100-pin TQFP
■ Three chip enables (CE1, CE2, CE3) for simple depth expansion
■ Automatic power-down feature available using ZZ mode or CE deselect
■ Burst capability – linear or interleaved burst order
■ Low standby powerApplication Scenarios
The CY7C147-45DC is commonly used in electronic devices that require high-speed data transfer, such as networking equipment, telecommunications devices, and high-performance computing systems.
Comparison
Advantages1. No Bus Latency™ (NoBL™) architecture eliminates dead cycles, improving data throughput.
2. Supports high-speed bus operations with zero wait states.
3. Pin compatible and functionally equivalent to ZBT™ devices.
4. Internally self-timed output buffer control eliminates the need to use OE.
5. Registered inputs allow for flow-through operation.
6. Supports byte write capability.
7. Low standby power consumption.Disadvantages1. Limited to a 3.3 V/2.5 V I/O supply (VDDQ).
2. The fast clock-to-output time of 6.5 ns may not meet the requirements of certain high-performance systems.
3. Limited to a 100-pin TQFP package. -
