Description

The CY7C346B-25JC belongs to the first-in first-out (FIFO) memories category under the IC chips classification. This electronic component is offered in a 600-mil wide and 300-mil wide package. It has a capacity of 256 words, and each word is 9 bits wide. Its design ensures that the data is read in the same order it was written. The device also features full and empty flags, which prevent underrun and overrun. It has three additional pins to enable expansion in width, depth, or both, and the depth expansion technique allows for parallel control signals from one device to another. It is an asynchronous buffer memory and is compatible with TTL.

Specifications and features

• Dual-ported RAM cell
• High speed 50 MHz read and write independent of depth and width
• Low operating power: ICC = 35 mA
• Empty and full flags (Half Full flag in standalone)
• TTL compatible
• Retransmit in standalone
• Expandable in width
• Pb-free packages available
• Pin compatible and functionally equivalent to IDT7200, IDT7201, IDT7202, IDT7203, IDT7204, AM7200, AM7201, AM7202, AM7203, and AM7204

Application Scenarios

The CY7C346B-25JC is commonly used as a buffer memory in various hardware systems such as microprocessors, microcontrollers, and digital signal processors. It can also be applied in communication systems, such as networking devices and routers.

Comparison

• Low operating power
• Expandable in width
• Compatible with TTL

• Smaller capacity compared to other FIFO memories
• May not be suitable for high-performance applications
