7200L12SOG8

Overview

The Renesas Electronics Corporation 7200L12SOG8 is an asynchronous FIFO memory device featuring a 256 x 9 organization and 2 kbit storage capacity. It operates with a bidirectional data bus and supports a maximum clock frequency of 50 MHz, achieving a 12 ns access time. The component functions within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum current of 80 mA. Designed for surface-mount applications, it utilizes an SOIC-28 package and maintains reliable operation across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling in multiprocessing environments.
• Includes Full and Empty flags to prevent data overflow and underflow conditions.
• Features Retransmit (RT) capability allowing the read pointer reset to its initial position upon low pulse activation.

Applications

• Multiprocessing systems requiring asynchronous data transfer
• Rate buffering applications
• Simultaneous read/write data management

Procurement Notes

Verify end-of-life status before procurement as the manufacturer has announced discontinuation. Confirm availability through authorized distributors only, noting potential long delivery times. Ensure compliance with RoHS requirements and moisture sensitivity levels specified in the official datasheet. Validate package integrity and pin configuration against the SOIC-28 specification prior to integration.

Selection Notes

Select this component for designs requiring 256 x 9 asynchronous FIFO functionality with bidirectional data buses. Consider the 12 ns access time and 50 MHz maximum frequency for timing constraints. Verify that the operating environment falls within the 0°C to +70°C range and that the 4.5 V to 5.5 V supply voltage aligns with system power rails. Evaluate the SOIC-28 package suitability for the target PCB layout.

Part Context

The 7200L12SOG8 belongs to the Renesas 7200L series of CMOS parallel FIFO memories. This series is engineered for high-speed data buffering in digital systems. The specific model integrates standard FIFO control logic with retransmit capabilities, distinguishing it from basic buffer components by providing advanced pointer management features for complex data flow scenarios.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the product's discontinued status. Cross-reference with other 7200L series variants such as 7200L12TPG or 7200L35J8 only if pin compatibility and electrical specifications match exactly.
