7200L25TPI

Overview

The Renesas Electronics Corporation 7200L25TPI is an asynchronous FIFO memory device with a storage capacity of 2.25K bits, organized as 256 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 80 mA. It utilizes a unidirectional bus architecture and is housed in a 28-PDIP package designed for through-hole mounting. The device functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes retransmit capability allowing reset of the read pointer to its initial position
• Utilizes Full and Empty flags to prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring asynchronous data transfer
• Rate buffering applications between different speed domains
• Industrial control systems operating within specified temperature ranges

Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance requirements as the part does not meet current standards. Check for valid replacement options such as the 7200L12JG series if available. Ensure supplier documentation matches the specific 28-PDIP package configuration. Validate lead times for obsolete inventory sources carefully.

Selection Notes

Select this component for designs requiring 256x9 word depth with unidirectional data flow. Consider the 28-PDIP package for through-hole assembly needs. Evaluate the 25 ns access time against system timing constraints. Verify that the 4.5 V to 5.5 V supply range aligns with existing power rails. Assess thermal performance within the -40°C to 85°C operational envelope.

Part Context

The 7200L25TPI belongs to the Renesas 7200 series of dual-port FIFO memories. This series is engineered for high-speed data buffering in complex digital systems. The TPI suffix denotes the specific 28-pin plastic dual in-line package variant. It serves as a specialized memory interface solution for bridging asynchronous logic blocks.
