CY7C4211-15AXC

FIFOs Memory Overview

The CY7C4211-15AXC is a 512 x 9 synchronous FIFO memory fabricated using advanced 0.65µm CMOS technology. It operates at a maximum frequency of 66.7 MHz with a minimum cycle time of 15 ns and an access time of 10 ns. The device features independent read and write clocks, programmable Almost Empty and Almost Full flags, and TTL-compatible inputs. It is housed in a 32-pin Pb-Free Thin Quad Flatpack (TQFP) package designed for commercial temperature ranges.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read/write operations via independent clock domains.
• Includes programmable status flags for precise buffer management.
• Features center power and ground pins to minimize electrical noise.
• Offers width expansion capability by connecting multiple devices.

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific ordering suffix 'AXC' confirms the Pb-Free TQFP package variant. Ensure the component meets the required commercial operating temperature range of 0°C to +70°C. Confirm that the 15 ns speed grade aligns with the system's timing requirements before integration.

FIFOs Memory Selection Notes

Select this part when a 512-word depth with 9-bit width is required. The -15 speed grade provides a 66.7 MHz operational limit suitable for moderate-speed interfaces. Consider the industrial -AI variant if operation below 0°C is necessary. Verify pin compatibility with existing IDT722X1 footprints if migrating designs.

FIFOs Memory Part Context

This component belongs to the CY7C42X1 family of high-speed, low-power synchronous FIFOs. The series includes densities ranging from 64x9 to 8Kx9 words. All members share identical pinouts and functional architectures, differing primarily in storage capacity and available speed grades.

FIFOs Memory Replacement Considerations

Pin-compatible and functionally equivalent substitutes include IDT72421, 72201, 72211, 72221, 72231, and 72241.
