7201LA15J8

Overview

The Renesas Electronics Corporation 7201LA15J8 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 supports data rates up to 40 MHz with a maximum access time of 15 ns. The component utilizes a unidirectional bus interface and is housed in a 32-PLCC package measuring 14x11.46 mm. It functions across a commercial temperature range of 0°C to 70°C and draws a maximum supply current of 80 mA.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• CMOS parallel interface technology
• Relay capability support

Applications

• Data buffering between different speed logic circuits
• Protocol conversion interfaces
• High-speed data acquisition systems

Procurement Notes

Verify the obsolete status and RoHS compliance details before procurement. Confirm moisture sensitivity level handling requirements during storage and assembly. Check for specific end-of-life notices or product change notifications that may affect long-term availability. Ensure the supplier provides valid traceability documentation for this discontinued part number.

Selection Notes

Select this component when a 512 x 9 word depth is required for unidirectional data buffering. Verify compatibility with 5V logic levels and PLCC-32 footprint constraints. Consider the 15 ns access time against system timing requirements. Evaluate alternative packages if surface-mount density differs from the specified leaded option.

Part Context

This part belongs to the 7201L series of CMOS parallel FIFOs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 7201LA12JG but differs in access speed specifications. The series targets general-purpose memory applications requiring simple asynchronous control logic without complex programmable flags.

Replacement Considerations

IDT7201LA15J8 is listed as an alias for this component.
