7200L12SOI

Overview

The Renesas Electronics Corporation 7200L12SOI is an asynchronous dual-port FIFO memory device with a storage organization of 256 x 9 bits, totaling 2 kbit capacity. It features a bidirectional data bus and operates within a supply voltage range of 4.5 V to 5.5 V. The component supports a maximum clock frequency of 50 MHz with a typical access time of 12 ns. Designed for multiprocessing and rate buffering applications, it utilizes Full and Empty flags to manage data flow and includes Retransmit capability for pointer reset. The device is housed in a 28-pin SOIC package.

Feature Summary

• Asynchronous dual-port architecture enabling simultaneous independent read and write operations
• Bidirectional data bus interface supporting flexible system integration
• Hardware-based overflow and underflow prevention using Full and Empty status flags
• Retransmit functionality allowing read pointer reset via low pulse activation

Applications

• Multiprocessing systems requiring asynchronous data exchange
• Rate buffer applications between mismatched speed interfaces
• Digital signal processing data path buffering
• Communication interface synchronization circuits

Procurement Notes

Verify the specific suffix 'SOI' against official Renesas documentation to confirm pinout compatibility and electrical characteristics, as variations exist within the 7200L series. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices or obsolescence warnings from the manufacturer. Ensure the selected package matches the target PCB footprint requirements. Validate lead times and availability through authorized distributors.

Selection Notes

Select this component when a 256 x 9 asynchronous FIFO with bidirectional data capability is required. The 12 ns access time suits high-speed digital interfaces up to 50 MHz. Consider the 28-pin SOIC package for surface-mount assembly. Evaluate power consumption at 80 mA maximum against system thermal constraints. Compare against unidirectional variants if bidirectional support is unnecessary for the specific application design.

Part Context

The 7200L series represents Renesas Electronics' line of CMOS asynchronous FIFO memories. These devices are designed for high-performance data buffering in complex digital systems. The 7200L12 variant specifically offers 12 ns access time, balancing speed and power efficiency. The series supports standard TTL logic levels, facilitating easy integration with various microprocessors and DSPs.

Replacement Considerations

Publicly confirmed substitute part numbers for 7200L12SOI were not identified in the provided source material. Verify cross-references with IDT-branded equivalents or other 7200L series members with compatible timing and package specifications.
