7201LA15TPI

Overview

The Renesas Electronics Corporation 7201LA15TPI is a 512 x 9 asynchronous dual-port FIFO memory device. It operates within a supply voltage range of 4.5 V to 5.5 V and features a 15 ns access time with a maximum data rate of 40 MHz. The component is housed in a 28-pin PDIP package and supports uni-directional bus architecture. It utilizes Full and Empty flags for data integrity management.

Feature Summary

• Asynchronous dual-port FIFO memory architecture
• First-in/first-out data loading and emptying mechanism
• Full and Empty flag status indicators

Applications

• Data buffering between disparate clock domains
• Interface bridging in high-speed digital systems
• Temporary storage in communication protocols

Procurement Notes

Verify the specific suffix TPI confirms the PDIP-28 package type, as other suffixes indicate different form factors like PLCC or SOIC. Confirm moisture sensitivity level requirements for your assembly process. Check current availability status as this part may be subject to long lead times or end-of-life restrictions depending on the distributor channel.

Selection Notes

Select this component when a 512-word by 9-bit depth is required for asynchronous data transfer. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 15 ns access speed against system timing constraints. Verify that the PDIP package style fits the PCB layout and manufacturing capabilities compared to surface-mount alternatives.

Part Context

This device belongs to the 7201L series of asynchronous FIFOs from Renesas. It shares architectural similarities with other members like the 7202 and 7204 but differs in memory density and package options. The 7201LA15 variant specifically denotes the 15 ns speed grade within the 512 x 9 organization family.

Replacement Considerations

The IDT7201LA15TPI is listed as an alias for this component. Other 7201 series variants exist with different speeds or packages, such as the 7201LA20J8 in PLCC-32. Verify pin compatibility and electrical specifications before substituting with non-alias parts.
