Overview
The Renesas Electronics Corporation 72235LB10JI is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 36K bits, organized as 2K words by 18 bits per word. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a PLCC-68 package.
Feature Summary
- Synchronous first-in-first-out memory architecture for efficient data buffering
- Supports high-speed operation up to 100MHz with rapid 6.5ns access times
- Configurable status flags to manage full and empty conditions
Applications
- Data buffering in multiprocessing systems
- Rate matching between asynchronous components
- Interprocessor communication interfaces
Procurement Notes
Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and moisture sensitivity handling requirements before installation. Cross-reference datasheet specifications against design constraints to ensure compatibility with existing system voltage and timing parameters.
Selection Notes
Select this component when a 2K x 18 synchronous FIFO is required for high-speed data buffering. Ensure the application environment supports the specified 4.5V to 5.5V operating voltage range. Verify that the PLCC-68 package footprint aligns with the target PCB layout and assembly capabilities.
Part Context
This part belongs to the Renesas 7200 series of synchronous FIFO memories. It shares functional similarities with other members like the 72235LB10TFG8 but differs in packaging and specific pinout configuration. The series is designed for applications requiring reliable data flow management in digital systems.
Replacement Considerations
Consider the IDT72235LB10J8 as a potential substitute based on shared naming conventions and similar specifications. Verify electrical and mechanical compatibility before implementation.
