7208L25JI8

Overview

The Renesas 7208L25JI8 is an asynchronous FIFO memory device with a storage capacity of 576K bits, organized as 64K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 28.5 MHz. The component features a 25 ns access time and draws a maximum supply current of 120 mA. It utilizes a unidirectional bus interface and is housed in a 32-PLCC package measuring 14x11.46 mm.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes auto-retransmit capability allowing reset of the read pointer to its initial position
• Provides status flags including Empty, Half-Full, and Full to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications between asynchronous clock domains
• Data acquisition systems needing temporary storage before processing

Procurement Notes

Verify component status carefully as this part may be discontinued or subject to limited availability. Confirm RoHS compliance requirements against specific project standards, as older variants may not meet current environmental regulations. Ensure the 32-PLCC package dimensions match the target PCB footprint exactly. Validate that the 4.5 V to 5.5 V operating voltage aligns with the system power supply design.

Selection Notes

Select this component when unidirectional asynchronous data transfer is required with a 9-bit word width. The 64K depth provides substantial buffering for burst data streams. Consider the 25 ns access speed relative to system clock frequencies. Evaluate the 120 mA maximum current consumption against thermal management capabilities. Verify compatibility with existing logic families operating at 5 V levels.

Part Context

This device belongs to the Renesas 7200 series of CMOS FIFO memories. It is functionally compatible with the broader 720X family, ensuring pin alignment for potential upgrades or replacements within similar designs. The series emphasizes low power consumption and ultra-high speed performance for industrial and commercial applications.
