7202LA50P

Overview

The Renesas Electronics Corporation 7202LA50P is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 9K organized as 1K x 9 bits. It operates with uni-directional bus direction and supports a maximum data rate of 15MHz with a typical access time of 50ns. The device functions within a supply voltage range of 4.5V to 5.5V and utilizes a PDIP-28 package. It employs Full and Empty flags for flow control, ensuring reliable data handling in first-in/first-out applications without requiring programmable logic.

Feature Summary

• Asynchronous operation enables independent read and write clock domains
• Uni-directional data transfer simplifies interface design
• Hardware-based Full and Empty status flags prevent buffer overflow or underflow

Applications

• Data buffering between disparate clock domains
• Interface bridging in communication systems
• Temporary data storage in embedded processing units

Procurement Notes

Verify the specific package variant, as the 7202LA50P designation may correspond to the PDIP-28 form factor based on available distributor data. Confirm RoHS compliance status directly with the manufacturer or authorized suppliers, as legacy components may have varying environmental declarations. Ensure the supplier provides valid traceability documentation for this discontinued or end-of-life part number to guarantee authenticity and quality assurance during procurement.

Selection Notes

Select this component when a simple, low-pin-count asynchronous FIFO is required for 9-bit wide data paths. The 50ns access time suits moderate-speed applications where high-frequency performance is not critical. Consider the PDIP-28 package if through-hole mounting is necessary for prototyping or specific mechanical constraints. Evaluate alternative packages like SOIC or PLCC if surface-mount technology is preferred for final production volumes.

Part Context

The 7202LA50P belongs to the Renesas 7200 series of asynchronous FIFO memories. This family provides dual-port memory functionality allowing simultaneous access by different system clocks. The 7202 variant specifically offers 1K x 9 bit depth, distinguishing it from wider or deeper configurations within the same product line designed for higher throughput requirements.

Replacement Considerations

Check for direct pin-compatible substitutes within the 7200 series, such as variants with different access times or package types. Verify that any replacement maintains the 1K x 9 architecture and asynchronous operation mode. Consult official substitution notices from Renesas for any officially recommended alternate part numbers.
