72235LB15PFGI8

Overview

The Renesas 72235LB15PFGI8 is a synchronous FIFO integrated circuit featuring a storage capacity of 36K bits, organized as 2K words by 18 bits. It operates with a maximum data rate of 66.7MHz and an access time of 10ns. The device supports unidirectional bus direction and functions within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 60mA. It is housed in a 64-TQFP package (14x14mm) and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with high-speed data transfer capabilities up to 66.7MHz
• Configurable memory depth and width organization for flexible system integration
• Supports programmable flags for status monitoring and control

Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between asynchronous logic systems
• Data acquisition systems requiring temporary storage

Procurement Notes

Verify component authenticity through authorized distributors due to End-of-Life status. Confirm RoHS3 compliance and moisture sensitivity level 3 handling requirements during procurement. Check for valid PCN documentation regarding assembly site changes or label modifications issued prior to the discontinuation date.

Selection Notes

Select this component for applications requiring 18-bit wide synchronous FIFO buffers with 10ns latency. Ensure power supply constraints align with the 4.5V to 5.5V operating range. Consider the 64-TQFP package dimensions for PCB layout compatibility and thermal management needs within the specified industrial temperature range.

Part Context

This part belongs to the Renesas 7200 series of high-performance synchronous FIFOs. It represents a legacy product line from IDT, now managed by Renesas Electronics. The device is designed for general-purpose memory buffering tasks where deterministic timing and high throughput are critical requirements for system performance.

Replacement Considerations

The manufacturer has declared this product End-of-Life. Verify if alternative parts within the same 72235 family or newer generations offer compatible pinouts and electrical specifications before finalizing design decisions.
