Overview
The Renesas Electronics Corporation 72235L15TF 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. The component supports unidirectional data transfer with an I/O frequency of up to 66 MHz and a typical access time of 10 ns. It operates on a single 5.0 V supply voltage within a range of 4.5 V to 5.5 V. The maximum supply current is 60 mA. The device is housed in a 64-pin TQFP package with dimensions of 10x10 mm. It supports programmable flags for status monitoring.
Feature Summary
- Synchronous operation with dedicated read and write clocks
- Programmable full and empty flag outputs
- Unidirectional bus architecture
- Surface-mount TQFP packaging
Applications
- High-speed data buffering between asynchronous systems
- Data acquisition system interfaces
- Network communication protocol converters
- Digital signal processing pipeline staging
Procurement Notes
Verify RoHS compliance status carefully, as listings vary; some variants are marked non-compliant. Confirm lead-free availability if required. Check for End-of-Life notices or obsolescence warnings from Renesas. Ensure the specific suffix matches the required package and temperature grade. Validate moisture sensitivity level handling procedures upon receipt.
Selection Notes
Select this part for applications requiring 18-bit wide synchronous buffering. Compare against the 72235LB variant for lead-free requirements. Consider the 72235L25 variant if slower speeds suffice. Verify package compatibility with existing PCB footprints. Ensure voltage levels match the 5V logic family constraints.
Part Context
This component is part of the IDT/Renesas 7200 series of high-performance synchronous FIFOs. It shares architectural similarities with other members like the 72225 and 72245 series, differing primarily in depth and speed grades. The 'L' suffix typically denotes standard commercial temperature ranges, while 'LB' indicates lead-free construction.
Replacement Considerations
Official substitutes include the 72235LB15PFI for lead-free versions. Cross-reference with IDT72235L15TF for legacy naming. Verify pinout compatibility before substitution. Check updated datasheets for any functional changes in newer revisions.
