CY7C4281V-10JXC

FIFOs Memory Overview

The CY7C4281V-10JXC is a high-speed, low-power synchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a storage organization of 64K x 9 bits, providing a total capacity of 576 Kbits. The component supports a clock frequency of 100 MHz with an access time of 8 ns. It operates within a supply voltage range of 3V to 3.6V and is housed in a 32-pin PLCC package.

FIFOs Memory Feature Summary

• Synchronous unidirectional FIFO architecture with clocked read and write interfaces
• High-speed operation supporting 100 MHz data rates
• Low-power CMOS technology for efficient energy consumption
• Nine-bit wide data bus configuration

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between asynchronous logic blocks
• Memory staging in telecommunications equipment
• Buffering in computer peripheral interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix JXC confirms the 32-pin PLCC package and lead-free RoHS compliance. Confirm the -10 speed grade corresponds to the required 8 ns access time for your design. Check current availability status as legacy components may have limited stock or require alternative sourcing strategies from authorized distributors.

FIFOs Memory Selection Notes

Select this part when a 64K x 9 synchronous FIFO is required with 8 ns latency. Ensure the system voltage aligns with the 3V to 3.6V operating range. Compare against the CY7C4261V, CY7C4271V, and CY7C4291V variants if different depth or width configurations are needed. Verify package compatibility with the 32-pin PLCC footprint.

FIFOs Memory Part Context

This component belongs to the CY7C42(6,7,8,9)1V family of synchronous FIFO memories. All members share similar functional characteristics but differ in memory depth and width. The CY7C4281V specifically provides the 64K x 9 configuration, distinguishing it from the 16K x 9 (CY7C4261V), 32K x 9 (CY7C4271V), and 128K x 9 (CY7C4291V) counterparts.

FIFOs Memory Replacement Considerations

Direct substitutes include CY7C4281V-10JC and CY7C4281V-10JXC. Verify pinout compatibility for the 32-pin PLCC package. Cross-reference with CY7C4261V, CY7C4271V, or CY7C4291V only if memory depth adjustments are acceptable in the design.
