7200L25TP

Overview

The Renesas Electronics Corporation 7200L25TP is an asynchronous FIFO memory device with a storage capacity of 2.25 kbit, organized as 256 words by 9 bits. It features a unidirectional bus and supports a maximum clock frequency of 28.5 MHz with a 25 ns access time. The component operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power consumption of 80 mA. It is housed in a 28-pin PDIP package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes Full and Empty flags to prevent data overflow and underflow
• Features Retransmit (RT) capability to reset the read pointer to its initial position

Applications

• Multiprocessing systems requiring asynchronous data transfer
• Rate buffering applications between mismatched data speeds
• Dual-port FIFO memory implementations

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead times due to potential discontinuation or limited availability. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

Selection Notes

Select this component for applications requiring reliable rate matching and data buffering. Consider the 25 ns access speed and 28.5 MHz limit when designing timing constraints. Verify that the 28-pin PDIP package fits the target PCB layout and assembly process.

Part Context

This part belongs to the 7200 series of asynchronous FIFO memories from Renesas Electronics. It provides a specialized solution for managing data flow in complex digital systems where precise synchronization between different processing speeds is critical.

Replacement Considerations

Check for official substitute part numbers provided by Renesas Electronics. Verify pinout and electrical specifications match exactly if considering alternative vendors.
