CY7C4211V-15AI

FIFOs Memory Overview

The CY7C4211V-15AI is a low-voltage, high-speed synchronous FIFO memory with a 512 x 9-bit architecture. It operates at frequencies up to 66 MHz with a 15 ns cycle time. The device features independent read and write clocks, allowing asynchronous operation. It includes programmable Almost Full and Almost Empty flags for precise buffer management. Input voltages are 5V-tolerant, while the core operates at 3.3 V. The component is housed in a 32-pin TQFP package.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read/write operations using independent clock domains.
• Provides programmable status flags for Almost Full and Almost Empty conditions with single-word granularity.
• Features 5V-tolerant inputs for easy integration into mixed-voltage systems.
• Includes width expansion capability for increasing data bus width.

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) as distinct from Commercial variants. Confirm the 'A32' package designation corresponds to the 32-pin TQFP form factor. Ensure the ordering code matches the 512 x 9 depth specification rather than the 256 x 9 variant. Cross-reference the datasheet revision *I for any updates to electrical characteristics or timing parameters before finalizing procurement specifications.

FIFOs Memory Selection Notes

Select this model when a 512-word depth is required for buffering applications. Choose this part over the CY7C4201V if larger buffer capacity is needed. The Industrial grade rating makes it suitable for environments with wider temperature fluctuations compared to Commercial grade options. Verify that the 3.3 V supply voltage aligns with the system design constraints.

FIFOs Memory Part Context

This component belongs to the CY7C42x1V family of low-voltage synchronous FIFOs manufactured by Cypress Semiconductor. The family includes variants with different depths, such as the 256 x 9 CY7C4201V. All members share similar architectural features, including 9-bit word widths and 3.3 V operation, but differ in storage capacity and specific speed grades.
