Overview
The Renesas Electronics Corporation 72235L15J is a synchronous FIFO memory device belonging to the 7200 series. It features an organization of 2K x 18 bits, providing a total storage capacity of 36 kilobits. The component supports unidirectional bus operation with a core voltage of 5.0V and operates within a temperature range of 0°C to 70°C. Key electrical specifications include an I/O frequency of 66 MHz and a maximum supply current of 60 mA. The device is housed in a 68-pin PLCC package with dimensions of 24.0 mm x 24.0 mm x 3.63 mm and a pitch of 1.27 mm.
Feature Summary
- Synchronous FIFO architecture supporting high-speed data transfer
- Unidirectional bus interface for dedicated read/write operations
- Programmable status flags for full and empty detection
Applications
- High-speed data buffering between asynchronous system domains
- Interface bridging in telecommunications equipment
- Data acquisition systems requiring temporary storage
Procurement Notes
Verify component authenticity through authorized channels as this part is obsolete. Confirm package integrity and pin alignment upon receipt. Check for moisture sensitivity level compliance before soldering. Ensure compatibility with existing 5V logic levels in the target design.
Selection Notes
Select this component for applications requiring 18-bit wide synchronous buffering at moderate speeds. Consider the PLCC package constraints for PCB layout. Evaluate thermal performance within the specified commercial temperature range. Verify that the 66 MHz clock requirement aligns with system timing constraints.
Part Context
Part of the IDT 7200 series synchronous FIFO family, designed for high-performance memory interfacing. The 72235 variant specifically targets 18-bit data paths. This series is widely used in legacy industrial and communication systems requiring reliable data synchronization without complex protocol overhead.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the product is discontinued, verify functional equivalence with newer Renesas or third-party FIFOs regarding pinout, voltage, and timing parameters.
