7207L25J8

Overview

The Renesas Electronics Corporation 7207L25J8 is an asynchronous FIFO memory device with a storage capacity of 288K bits, organized as 32K words by 9 bits. It features a unidirectional bus direction and supports retransmit capability. The component operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum supply current of 120 mA. It offers a data rate of 22.22 MHz and an access time of 35 ns. The device is housed in a 32-PLCC package (14x11.46 mm) and functions within a commercial temperature range of 0°C to 70°C.

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
• Utilizes Full and Empty status flags to prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring data buffering
• Rate buffer applications between asynchronous domains
• Data acquisition systems needing temporary storage

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility with existing designs before integration. Check for moisture sensitivity handling procedures during assembly. Ensure replacement strategies are in place given discontinued manufacturing status.

Selection Notes

Select this component for applications requiring reliable asynchronous data buffering with specific 9-bit word width constraints. Consider the 35 ns access time suitability for target system clock speeds. Evaluate the PLCC package form factor against available PCB real estate. Assess power consumption limits against system thermal design capabilities. Verify operational temperature range matches the intended deployment environment.
