CY7C4211V-15AXI

FIFOs Memory Overview

The CY7C4211V-15AXI is a low-voltage, high-speed synchronous FIFO memory with a storage organization of 512 words by 9 bits. It operates at a maximum frequency of 66.7 MHz with a cycle time of 15 ns and an access time of 11 ns. The device functions on a 3.3 V supply (3.0 V to 3.6 V) and draws a maximum active current of 20 mA. It features 5 V-tolerant inputs, independent read and write clocks, and programmable Almost Full/Empty flags. Packaged in a 32-pin TQFP, it supports industrial temperature ranges from -40 °C to +85 °C.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read/write operations using independent clock domains.
• Includes programmable status flags for precise buffer management and flow control.
• Features 5 V-tolerant inputs for seamless integration into mixed-voltage systems.
• Provides width expansion capability through parallel connection of multiple devices.

FIFOs Memory Applications

• High-speed data acquisition systems
• Multiprocessor interface buffering
• Communications data buffering

FIFOs Memory Procurement Notes

Verify the specific suffix 'AXI' confirms the Industrial temperature grade (-40 °C to +85 °C) and 32-pin TQFP package. Confirm RoHS compliance status via the manufacturer's latest documentation. Check for end-of-life notices as Cypress Semiconductor assets were acquired by Infineon Technologies.

FIFOs Memory Selection Notes

Select this component when a 512-word depth and 9-bit data width are required for synchronous buffering. Ensure the design accommodates independent read and write clock domains. Verify that the 3.3 V operating voltage aligns with the system power rails and that 5 V tolerance is needed for input interfacing.

FIFOs Memory Part Context

This part belongs to the CY7C42x1V family of low-voltage synchronous FIFOs. It shares architectural similarities with the CY7C4201V but offers double the depth (512 vs 256 words). The series utilizes advanced CMOS technology to achieve high speed and low power consumption suitable for embedded applications.

FIFOs Memory Replacement Considerations

CY7C4201V-15AXI: Offers identical electrical characteristics and pinout but with reduced depth (256 x 9).

FIFOs Memory FAQ

How are the Almost Full and Almost Empty flags configured?

The offset values for these flags are programmed into internal registers using the WEN2/LD and WEN1 pins during reset configuration.

Can the read and write clocks operate independently?

Yes, the device supports asynchronous read and write operations using separate RCLK and WCLK signals.
