IDT7204L25SOI

FIFOs Memory Overview

The IDT7204L25SOI is an asynchronous FIFO memory device manufactured by Renesas Electronics. It features a storage organization of 4K x 9 bits, providing a total capacity of 36 kbit. The component supports bidirectional data bus operation and operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a maximum access time of 25 ns and a maximum clock frequency of 28.5 MHz. The device is housed in a PLCC-32 package and is designed for surface mount installation. It functions as a dual-circuit unit with asynchronous timing control.

FIFOs Memory Feature Summary

• Asynchronous first-in-first-out memory architecture for buffering data streams
• Bidirectional data bus interface supporting flexible system integration
• CMOS technology ensuring low power consumption during operation

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific suffix 'SOI' against official Renesas documentation, as standard listings often use 'JI' or 'SOGI'. Confirm RoHS compliance status, as older variants may not meet current environmental standards. Check for end-of-life notices, as this part number appears discontinued in several major distributor catalogs. Ensure moisture sensitivity level handling procedures are followed if the component has been exposed to ambient conditions.

FIFOs Memory Selection Notes

Select this component when a 4K x 9 asynchronous FIFO with 25 ns access time is required. Compare against the 7204L15 series if faster 15 ns performance is needed. Consider the PLCC-32 package constraints versus SOIC alternatives like the 7204L25SOGI. Verify that the bidirectional bus requirement matches the target system design, as some applications may require unidirectional interfaces found in other family members.

FIFOs Memory Part Context

This component belongs to the Renesas 7204L series of asynchronous FIFOs. The series typically offers various speed grades and packaging options to suit different design requirements. The 7204L25 variant specifically targets applications requiring moderate speed with a 25 ns access time. The manufacturer transitioned from IDT branding to Renesas Electronics following corporate acquisitions.

FIFOs Memory Replacement Considerations

Publicly confirmed substitutes include the 7204L15JI and 7204L12JG. These alternatives offer similar functionality but with different access times (15 ns and 12 ns respectively). Verify pin compatibility and electrical characteristics before substitution.
