72V251L10PFGI8

FIFOs Memory Overview

The Renesas Electronics Corporation 72V251L10PFGI8 is a synchronous First-In, First-Out (FIFO) memory device belonging to the 72V251 family. It features a data bus width of 9 bits and an organization of 256 x 9, resulting in a total storage capacity of 2 Kbit. The component supports a maximum clock frequency of 100 MHz with an access time of 10 ns. It operates within a supply voltage range of 3 V to 3.6 V and functions at temperatures between -40°C and +85°C. The device is housed in a 32-pin TQFP package.

FIFOs Memory Feature Summary

• Synchronous operation with independent read and write clocks allows simultaneous data handling.
• Supports retransmit operations with fixed, low first word data latency.
• Includes programmable flags for empty, full, half-full, almost-empty, and almost-full states.
• Designed for easy expansion in both depth and width.

FIFOs Memory Applications

• Data buffering for graphics systems
• Local area network interfaces
• Interprocessor communication

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for product discontinuance notices prior to procurement. Ensure the specific suffix matches required packaging and temperature grades. Validate that the source document corresponds to the exact part number to avoid functional mismatches.

FIFOs Memory Selection Notes

Select this component when a 9-bit wide synchronous FIFO with 256-word depth is required. It is suitable for applications needing 100 MHz performance and 3.3V operation. Consider the 32-pin TQFP package constraints. Verify compatibility with system voltage levels and interface requirements against similar devices in the 72V2xx series.

FIFOs Memory Part Context

This device is part of the Renesas 72V251 series of SuperSync FIFOs. It serves as a 3.3V version of older 5V devices, offering lower power consumption while maintaining functional compatibility. The series is designed for high-speed data buffering in digital signal processing and communication applications.

FIFOs Memory Replacement Considerations

Check for pin-compatible alternatives within the 72V2x1 family. Verify functional equivalence with IDT72V21x1 series devices. Confirm that any substitute maintains the same 9-bit width, 256-depth organization, and 10ns access time specifications.
