7206L20TP

Overview

The Renesas Electronics Corporation 7206L20TP is an asynchronous FIFO memory device with a storage capacity of 144K bits, organized as 16K words by 9 bits. It supports unidirectional data transfer at a maximum clock frequency of 33.3MHz and features a 20ns access time. The component operates on a single 5V supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 120mA. It is housed in a 28-pin PDIP package designed for through-hole mounting and functions within an industrial temperature range of 0°C to 70°C.

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 status flags to prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate matching between components operating at different clock speeds
• Data acquisition systems needing temporary storage before processing

Procurement Notes

Verify the specific suffix 'TP' against official Renesas documentation to confirm the exact package dimensions and lead finish specifications. Ensure that the required operating temperature range aligns with the commercial grade limits defined in the datasheet. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy parts may have varying environmental declarations depending on production date and region.

Selection Notes

Select this component when a unidirectional asynchronous interface is required for 9-bit wide data paths. The 20ns access speed suits moderate-to-high throughput applications where simultaneous independent read and write clocks are necessary. Consider the 28-pin DIP form factor if through-hole assembly is mandated by the PCB design constraints or mechanical stability requirements.

Part Context

This device belongs to the 7206 series of advanced CMOS FIFO memories manufactured by Renesas Electronics. The series is characterized by low power consumption and high-speed performance, offering expandability in both word depth and bit width. It serves as a critical interface element in digital signal processing chains and communication protocols requiring reliable first-in-first-out data handling.

Replacement Considerations

The 7206L15JG is listed as an upgrade alternative by the manufacturer. Verify pin compatibility and timing differences before substitution.
