Description

The CY7C341B-35JI is an IC chip which belongs to the FIFO memory family. This chip is offered in both 300-mil wide and 600-mil wide packages, with a capacity of 4096 words and a 9-bit word length. This memory is organized to read data in the same sequential order it was written, and it features full and empty flags to prevent overrun and underrun. Additionally, three pins are provided for width and depth expansion, which can be steered in parallel to avoid propagation delays and maintain throughput.

Application Scenarios

The CY7C341B-35JI is suitable for a wide range of electronic applications, including telecommunications, data processing, and networking. It is commonly used in buffering data in communication systems, storing data in microprocessors, and buffering data on memory buses.

Comparison

• High speed read/write operations, independent of depth and width
• Dual-ported RAM cell
• Provides full and empty flags to prevent overrun and underrun
• Expandable in width and depth
• Pin compatible and functionally equivalent to other popular FIFO memories

• Not suitable for high-capacity storage requirements
• May not meet the performance requirements of some high-speed applications
• May require additional components for applications requiring more than 4,096 words
