7207L15JI8

Overview

The Renesas Electronics Corporation 7207L15JI8 is a high-speed asynchronous FIFO memory device belonging to the 7207L series. It features a storage organization of 32K words by 9 bits, providing a total capacity of 288 Kbits. The component supports simultaneous and independent read and write operations with an access time of 15 nanoseconds. It operates on a single 5.0V power supply within a voltage range of 4.5V to 5.5V. The device is housed in a 32-lead Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes status flags such as Full, Empty, and Half-Full to manage data flow
• Features retransmit capability allowing reset of the read pointer to its initial position

Applications

• Multiprocessing systems requiring rate buffering
• Data acquisition systems needing temporary storage
• Communication interfaces managing speed mismatches between components

Procurement Notes

Verify the specific suffix 'I' against official Renesas documentation to confirm industrial temperature grade specifications. Confirm moisture sensitivity level and lead-free status prior to ordering. Check current lifecycle status as older variants may be discontinued or subject to last-time buy notices. Ensure compatibility with existing PCB footprints for the 32-PLCC package.

Selection Notes

Select this component when a 32K x 9 word depth is required with 15ns performance. Compare against the 7207L20 variant if slower speeds are acceptable for lower power consumption. Consider the 7207L35J8 only if pinout compatibility is verified despite different timing characteristics. Evaluate package availability constraints for the PLCC form factor.

Part Context

This part belongs to the Renesas 7207L family of CMOS parallel FIFO memories. The family is designed for high-speed data buffering in digital signal processing and communication networks. The 7207L15 variant specifically targets applications requiring faster throughput compared to standard 20ns or 35ns devices while maintaining low power consumption typical of CMOS technology.

Replacement Considerations

Official upgrade alternatives include the 7207L15JG8. Verify functional equivalence regarding pinouts and electrical parameters before substitution.
