7202LA35TP

Overview

The Renesas Electronics Corporation 7202LA35TP is a uni-directional asynchronous FIFO memory with a storage capacity of 9K (1K x 9). It features a 35ns access time and operates at a data rate of 22.2MHz. The device supports a supply voltage range of 4.5V to 5.5V and functions within an operating temperature range of -55°C to 125°C. It is housed in a 28-PDIP package.

Feature Summary

• Asynchronous dual-port architecture for independent read and write clock domains
• Uni-directional bus configuration with Full and Empty status flags
• Relay capability support for signal integrity

Applications

• Data buffering between asynchronous systems
• Clock domain crossing interfaces
• High-speed data acquisition systems

Procurement Notes

Verify the specific suffix 'TP' confirms the 28-PDIP through-hole package variant, as other suffixes indicate different form factors like PLCC or LCC. Confirm RoHS compliance status, as older 7202 series variants may not meet current environmental standards. Check for obsolescence notices from Renesas, as this component family has faced discontinuation announcements. Ensure the required operating temperature range matches the industrial specification if used in harsh environments.

Selection Notes

Select this part when a uni-directional asynchronous interface is required with a 1K x 9 word depth. The 35ns access time suits moderate-speed applications compared to faster 12ns or 25ns variants. Verify that the 28-PDIP package fits the PCB layout constraints, as surface-mount alternatives exist in the same family. Ensure the system design accommodates the 4.5V to 5.5V power supply requirements typical of this CMOS logic family.

Part Context

The 7202LA35TP belongs to the Renesas 7200 series of asynchronous FIFOs, originally developed by IDT. This series provides reliable first-in/first-out memory management for digital systems. The 7202LA variant specifically denotes the 1K x 9 organization. The component represents a legacy high-performance memory solution widely used in telecommunications and industrial control before newer integrated solutions became prevalent.

Replacement Considerations

Public confirmed substitutes include the 7202LA12JG for faster performance upgrades. Verify pin compatibility and electrical specifications before substitution.
