7206L50TP

Overview

The Renesas Electronics Corporation 7206L50TP 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 15 MHz with a 50 ns access time. The component features unidirectional bus directionality and is housed in a 28-PDIP package designed for through-hole mounting. It functions within an industrial temperature range of 0°C to 70°C and has a maximum supply current of 120 mA.

Feature Summary

• Asynchronous read and write operations allow simultaneous independent control of input and output data streams without a shared clock requirement.
• Retransmit capability enables the reset of the read pointer to its initial position when the retransmit signal is pulsed low, preventing data loss during specific operational states.
• Status flags including Empty, Half-Full, and Full are provided to prevent data overflow and underflow conditions during system operation.

Applications

• Multiprocessing systems requiring asynchronous data transfer between processors.
• Rate buffering applications where data rates between source and destination differ.
• Digital signal processing interfaces requiring temporary data storage.

Procurement Notes

Verify component authenticity due to discontinued status. Confirm package integrity as moisture sensitivity level is specified. Check RoHS compliance requirements against project specifications as the part may not meet current environmental standards. Ensure pin compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component for applications requiring 16K x 9 word depth with asynchronous interface capabilities. Consider the 50 ns access speed and 15 MHz data rate limits for timing constraints. Evaluate the 28-PDIP through-hole package suitability for mechanical mounting requirements. Verify power supply stability within the 4.5 V to 5.5 V range for reliable operation.

Part Context

The 7206L50TP belongs to the Renesas 7206 series of CMOS parallel FIFO memories. This series offers high-speed data buffering solutions with expandable depth and width options. The device is functionally compatible with earlier 720X family members, facilitating design upgrades while maintaining pin configurations.
