7206L25TP

Overview

The Renesas Electronics Corporation 7206L25TP 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 data rate of 40 MHz with a 15 ns access time. The component features unidirectional bus directionality and includes retransmit capability. It is housed in a 28-PDIP package designed for through-hole mounting and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Retransmit (RT) capability allowing reset of the read pointer to its initial position
• Status flags including Empty, Half-Full, and Full to prevent data overflow and underflow
• Fully expandable architecture supporting expansion by both word depth and bit width

Applications

• Multiprocessing systems requiring asynchronous data transfer
• Rate buffering applications between mismatched data speeds
• Data acquisition systems needing temporary storage buffers

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity and pin compatibility during replacement planning. Check RoHS compliance requirements against project specifications. Validate lead times from authorized distributors or secondary market sources. Ensure proper handling procedures are followed for obsolete semiconductor components.

Selection Notes

Select this component when a 16K x 9 asynchronous FIFO with 15 ns access time is required. Consider the 28-PDIP package for through-hole assembly needs. Evaluate the 40 MHz data rate against system timing constraints. Verify that the unidirectional bus configuration meets interface requirements. Assess thermal performance within the specified industrial temperature range.

Part Context

The 7206L25TP belongs to the Renesas 7206 series of high-speed CMOS FIFO memories. This series provides dual-port functionality with full hardware handshaking. The device is part of a broader family offering various speed grades and package options. It is designed for applications demanding reliable first-in/first-out data storage without complex control logic.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Designers should evaluate functional equivalents with compatible pinouts and electrical characteristics. Verify that any alternative device supports the same 16K x 9 organization and asynchronous operation mode.
