Application Scenarios

The CY7C4271-10AC is a versatile IC chip that provides solutions for various data buffering needs, including but not limited to:

• High-speed data acquisition
• Multiprocessor interfaces
• Communication buffering

Comparison

• Clocked read and write interface for maximum data transfer efficiency
• Low power consumption with high-speed operation (ICC = 35mA)
• Programmable Automatic Full and Almost Empty flags for data status monitoring
• Pin-compatible with CY7C42X1 family and IDT72201/11/21/31/41/51, allowing for density upgrade
• Can be cascaded to increase FIFO width for expanding data buffering needs

• The CY7C4271-10AC is specific to 9 bit-width data transfer needs, which may not be ideal for some applications
• Slightly more expensive compared to some other FIFO memory chip alternatives
