72V235L15PF

FIFOs Memory Overview

The Renesas 72V235L15PF is a synchronous FIFO memory device organized as 1K x 18 bits, providing a total storage capacity of 18 kbit. It operates with a maximum clock frequency of 66.7 MHz and features a typical access time of 15 ns. The component supports unidirectional data transfer and functions within a supply voltage range of 3 V to 3.6 V. It is housed in a 64-pin TQFP package and is designed for industrial temperature ranges.

FIFOs Memory Feature Summary

• Supports synchronous operation with independent read and write clocks for flexible data buffering applications.
• Features programmable flags including full, empty, almost-full, and almost-empty indicators for system status monitoring.
• Includes First Word Fall Through (FWFT) capability to reduce latency in high-speed data processing scenarios.

FIFOs Memory Applications

• Data buffering in telecommunications equipment
• Interface bridging between processors operating at different clock speeds
• Network interface card data storage

FIFOs Memory Procurement Notes

Verify the specific suffix designation carefully, as variants such as L15PFI or L15PF8 may differ in packaging type or moisture sensitivity level. Confirm RoHS compliance status directly from the manufacturer datasheet, as older production runs may not meet current environmental standards. Ensure the selected variant matches the required operating temperature range for the intended application environment.

FIFOs Memory Selection Notes

Select this component when a 1K x 18 bit synchronous FIFO is required with 15 ns access speed. Consider the 72V235 series if unidirectional data flow and programmable flag outputs are necessary. Evaluate the 64-pin TQFP package constraints against PCB layout requirements. Compare against faster access time variants if system timing budgets are tighter than 15 ns.

FIFOs Memory Part Context

This part belongs to the Renesas 72V2x5 family of synchronous FIFO memories, which are widely used for data rate matching and buffering. The 72V235 variant specifically offers 1K depth, distinguishing it from the 512-depth 72V215 and 2K-depth 72V235 models. These devices are engineered for reliable performance in digital signal processing and communication systems requiring precise data synchronization.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the 72V235 series, such as the 72V235L10PFG for faster 10 ns access times. Verify that any replacement maintains the same 1K x 18 organization and 3.3V operating voltage. Consult official Renesas documentation for approved cross-reference lists to ensure functional equivalence.
