7203L35TP

Overview

The Renesas Electronics Corporation 7203L35TP is a discontinued asynchronous FIFO memory component. It features a 2k x 9 organization, providing 18 kilobits of density. The device operates with a core voltage of 5.0V and utilizes TTL-compatible I/O levels. It offers an access time of 35 nanoseconds and supports uni-directional data transfer architecture. The component is housed in a 28-lead PDIP package with a pitch of 2.54mm. The specified operating temperature range extends from 0°C to 70°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional bus architecture for sequential data flow
• TTL-compatible input and output interface levels

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems with different clock speeds
• Temporary storage in high-speed digital signal processing chains

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability requires direct consultation with authorized distributors, as stock status varies significantly. Sourcing may involve surplus channels rather than standard factory supply. Confirming the specific manufacturing lot and authenticity is critical due to the discontinuation status. Ensure that any available units meet the required environmental specifications before integration into new designs.

Selection Notes

Designers should evaluate alternative components due to the obsolete status of this part. Consider modern asynchronous FIFOs with similar 2k x 9 depth and 35ns access times. Verify compatibility with existing 5.0V logic levels and PDIP packaging constraints if replacement within the same form factor is necessary. Check for updated RoHS compliance and extended temperature ranges in successor families.

Part Context

The 7203 series belongs to a family of asynchronous FIFO memories produced by Renesas Electronics (formerly IDT). These components are designed for applications requiring temporary data storage and synchronization between asynchronous systems. The 7203L35TP specifically represents the 35ns speed grade within the 2k x 9 capacity segment of this product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, no direct official replacements are listed. Engineers must identify third-party equivalents based on functional specifications such as 2k x 9 organization, 35ns access time, and 5.0V operation.
