72265LA10TF

Overview

The Renesas Electronics Corporation 72265LA10TF is a SuperSync FIFO memory device with a storage capacity of 144K bits, organized as 8K words by 18 bits. It operates on a single 3.3V supply voltage ranging from 3V to 3.6V and supports data rates up to 66.7MHz with a 10ns access time. The component utilizes a synchronous interface within a 64-pin TQFP package (14x14mm) and functions in an industrial temperature range of 0°C to 70°C.

Feature Summary

• SuperSync architecture enabling independent read and write clocks for simultaneous operations
• Uni-directional bus configuration with programmable status flags
• Low power consumption via auto power down capabilities
• Fixed low first word data latency supporting retransmit operations

Applications

• Networking data buffering
• Video signal processing
• Telecommunications systems
• Data communications rate matching

Procurement Notes

Verify the exact suffix designation carefully, as the 72265LA10TF may be listed under similar identifiers like 72V265LA10TFG or 72V255L15TF in distributor catalogs. Confirm RoHS compliance status and moisture sensitivity level prior to ordering, as legacy components often have specific handling requirements and limited availability.

Selection Notes

Select this component when a synchronous FIFO with 18-bit width and 8K depth is required for 3.3V logic interfaces. Ensure the design accommodates the 64-pin TQFP footprint and that the 66.7MHz maximum frequency meets system timing constraints. Verify compatibility with existing clocking schemes given the independent RCLK and WCLK inputs.

Part Context

This part belongs to the Renesas 72V265 series of SuperSync FIFOs, designed as a functional replacement for older 5V 722x5 family devices. It maintains pin compatibility while reducing power consumption through 3.3V operation. The series is widely used in high-speed digital applications requiring reliable data buffering between asynchronous domains.

Replacement Considerations

The 72V255LA10TFG is documented as an upgrade alternative. Verify electrical parameter alignment and pinout compatibility before substitution.
