7201LA15JI8

Overview

The Renesas Electronics Corporation 7201LA15JI8 is an asynchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum data rate of 40 MHz with a 15 ns access time. The component is housed in a 32-PLCC package and supports unidirectional bus directionality.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Built-in status flags including Full, Empty, and Half-Full indicators
• Retransmit capability allowing reset of the read pointer to its initial position

Applications

• Multiprocessing systems requiring data buffering
• Rate matching between components operating at different speeds
• Data acquisition systems needing temporary storage

Procurement Notes

Verify RoHS compliance status and moisture sensitivity level prior to ordering. Confirm current availability as the product may be discontinued or subject to long lead times. Ensure the PLCC-32 package matches the target PCB footprint and that the 4.5 V to 5.5 V supply voltage aligns with system power rails.

Selection Notes

Select this component for applications requiring high-speed asynchronous data buffering with a 9-bit word width. The 15 ns access time suits moderate-speed digital interfaces. Verify compatibility with existing logic levels and ensure the 32-pin PLCC package fits the mechanical constraints of the design.

Part Context

This part belongs to the 7201L series of CMOS parallel FIFOs from Renesas Electronics. It is functionally compatible with other members of the 7201 family, sharing similar pinouts and operational characteristics while differing in speed grades or packaging options.
