7203L15TPI

Overview

The Renesas Electronics Corporation 7203L15TPI is an asynchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K words by 9 bits. It features a unidirectional bus architecture and supports a maximum data rate of 40 MHz with a 15 ns access time. The component operates on a single 5.0 V core voltage within a range of 4.5 V to 5.5 V, drawing a maximum supply current of 120 mA. It is housed in a 28-pin PDIP package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Unidirectional bus architecture for dedicated data flow control
• Retransmit capability allowing read pointer reset via external pulse
• Hardware status flags including Empty, Half-Full, and Full indicators

Applications

• Multiprocessing systems requiring asynchronous data buffering
• Rate matching between components operating at different clock speeds
• Data acquisition systems needing temporary storage before processing
• High-speed interface bridging in telecommunications equipment

Procurement Notes

Verify the specific suffix TPI confirms the 28-pin PDIP package type and through-hole mounting style. Confirm the RoHS compliance status, as documentation indicates non-compliance for this series. Check for End-of-Life (EOL) notices or discontinuation announcements from Renesas. Ensure the supplier provides traceability documentation for MIL-STD-883 Class B availability if required for your application.

Selection Notes

Select this component when a unidirectional asynchronous FIFO with 18K bit depth is required. The 15 ns access time suits high-speed applications up to 40 MHz. Consider the 28-pin PDIP package only if through-hole assembly is mandated. Verify that the 5.0 V TTL I/O levels match the system logic requirements. Compare against other 7203 variants if bidirectional support or different packaging options are needed.

Part Context

This part belongs to the Renesas 7203 family of asynchronous FIFOs, designed for high-performance data buffering. The family shares architectural similarities but varies in speed grades, organization, and package types. The 7203L15 variant specifically targets applications requiring 15 ns performance. It is functionally compatible with earlier IDT 7203 designs, facilitating migration for existing systems.

Replacement Considerations

Direct substitutes include the IDT7203L15TPI. Other pin-compatible options within the 7203 series may exist but require verification of speed grade and package dimensions.
