7206L25TPI

Overview

The Renesas Electronics Corporation 7206L25TPI is an asynchronous FIFO memory device with a storage capacity of 144K bits, organized as 16K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 28.5 MHz. The component features a 25 ns access time and is housed in a 28-pin PDIP package. Designed for unidirectional data flow, it includes status flags for empty, half-full, and full conditions to manage data overflow and underflow effectively.

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 flags to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring rate buffering
• Data acquisition systems needing temporary storage
• Interface circuits between devices operating at different clock speeds

Procurement Notes

Verify component authenticity due to obsolete lifecycle status. Confirm package integrity and pin alignment against the 28-PDIP specification. Check datasheet revisions for any parameter changes. Ensure compatibility with existing system voltage levels. Validate supplier documentation for traceability.

Selection Notes

Select this part for applications requiring 16K x 9 word depth and 25 ns access speed. Ensure the design accommodates the 4.5 V to 5.5 V supply range. Consider the unidirectional bus architecture when designing interface logic. Verify that the 28-pin DIP package fits the target PCB layout constraints.

Part Context

This component belongs to the 7206 series of high-speed asynchronous FIFOs. It is functionally compatible with the broader 720X family, offering low power consumption and ultra-high speed performance. The series is designed for robust data handling in complex electronic systems requiring reliable first-in/first-out memory management.
