7207L25PDG

Overview

The Renesas Electronics Corporation 7207L25PDG 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 architecture and supports data rates up to 28.5MHz with a maximum access time of 25ns. The component operates on a single 5.0V supply voltage within a range of 4.5V to 5.5V and draws a maximum supply current of 120mA. It is housed in a 28-pin PDIP package and is rated for industrial operating temperatures between -40°C and +85°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 rate buffering
• Data acquisition systems needing temporary storage
• Digital signal processing interfaces

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and moisture sensitivity handling procedures before installation. Review official datasheets for pin compatibility and electrical specifications to ensure system integration requirements are met without relying on general market assumptions.

Selection Notes

Select this component when a unidirectional asynchronous FIFO with 9-bit word width is required. Ensure the design accommodates the 28-pin PDIP form factor and 5V logic levels. Consider the 25ns access speed against system timing constraints and verify that the industrial temperature range aligns with environmental operating conditions.

Part Context

This part belongs to the 7207 series of high-speed asynchronous FIFOs manufactured by Renesas Electronics. The series is designed for applications requiring reliable data buffering between asynchronous clock domains. The 7207L25PDG specifically denotes the 25ns speed grade within the 32K x 9 organization family.
