72235LB12TF

Overview

The Renesas 72235LB12TF is a synchronous FIFO memory device with a capacity of 2K x 18 bits. It operates at a maximum data rate of 60 MHz and features a 12 ns access time. The component supports a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 60 mA. It is housed in a 64-pin TQFP package and is designed for surface-mount installation.

Feature Summary

• Synchronous single-directional bus architecture
• Programmable status flags support
• Standard TTL interface compatibility

Applications

• High-speed data buffering in digital signal processing systems
• Interface bridging between asynchronous logic blocks
• Data storage in telecommunications equipment

Procurement Notes

Verify the obsolete status and end-of-life notices before procurement planning. Confirm moisture sensitivity level handling requirements during storage and assembly. Check for RoHS compliance restrictions as indicated by manufacturer documentation. Ensure availability through authorized channels due to discontinuation status.

Selection Notes

Select this component for applications requiring 18-bit wide synchronous FIFO buffers. Compare access times against system clock requirements. Verify package compatibility with existing PCB footprints. Consider alternative speeds within the 72235 series if higher throughput is needed.

Part Context

Part of the Renesas 7200 series synchronous FIFO family. Shares architectural similarities with variants like 72235LB10 and 72235LB15. Designed for high-performance memory buffering tasks in industrial and communication applications.

Replacement Considerations

Check for direct pin-compatible substitutes within the same series. Evaluate 72235LB10TF8 or 72235LB15TF for speed differences. Verify functional equivalence before substitution.
