Description

The CY7C342B-15RI is an asynchronous First-In-First-Out (FIFO) buffer memory that belongs to the IC Chips product category. It is a type of memory that allows users to store and retrieve data, where data is read sequentially in the same order it was written. It is organized into 256 words by 9 bits wide, that can be easily expanded, facilitating unlimited expansion in depth and width, with high-speed operation and low-power consumption features.

Specifications and features

The CY7C342B-15RI has the following features:

• 256 x 9 asynchronous First-In-First-Out (FIFO) buffer memory.
• Dual-ported RAM cell.
• High-speed 50 MHz read and write, independent of depth and width.
• Low operating power: ICC= 35mA.
• Empty and full flags that prevent overrun and underrun.
• TTL compatible.
• Retransmit in standalone mode.
• Expandable in width.
• Pin compatible and functionally equivalent to IDT7200, IDT7201, IDT7202, IDT7203, IDT7204, AM7200, AM7201, AM7202, AM7203, and AM7204.

Application Scenarios

The CY7C342B-15RI FIFO buffer memory is used in different applications, including computer networking, data communications, and signal processing, where data is stored, and retrieved with high speed and low power consumption.

Comparison

• Low-power consumption.
• High-speed read and write.
• Expandable in width and depth for unlimited expansion.
• Pin Compatible with a wide range of brand devices.
• Prevents overrun and underrun.

• Suitable for small data storage as it has 256 words capacity.
• It may not be suitable for complex applications that require larger memory size and complex data organization.
