Overview
The 72235L15PF is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 36K bits, organized as 2K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 3V to 3.6V and has a maximum supply current of 30mA. The device is housed in a 64-TQFP package (14x14mm) and functions within a commercial temperature range of 0°C to 70°C.
Feature Summary
- Synchronous first-in, first-out memory architecture for efficient data buffering
- Supports First-Word-Fall-Through (FWFT) functionality for rapid data availability
- Programmable flags enable customizable status monitoring
- Unidirectional bus direction simplifies interface design
Applications
- Data buffering in high-speed digital communication systems
- Interface bridging between components operating at different clock domains
- Temporary storage in embedded processing applications
Procurement Notes
Verify the specific suffix 'PF' against official Renesas documentation to confirm the exact package type and tape/reel specifications. Confirm RoHS compliance status, as some sources indicate non-compliance. Check for obsolescence notices or end-of-life announcements prior to procurement. Ensure the 3V to 3.6V supply voltage requirement aligns with the target system design.
Selection Notes
Select this component when a 18-bit wide synchronous FIFO with 2K depth is required. The 10ns access time and 66.7MHz speed suit moderate-to-high frequency applications. Consider the 3V to 3.6V operating voltage range for compatibility with low-voltage logic families. The 64-pin TQFP package offers a surface-mount solution suitable for dense PCB layouts.
Part Context
This part belongs to the 72V series of synchronous FIFOs from Renesas. It shares architectural similarities with other members like the 72231L15PF but differs in word width and capacity. The 72V series is designed for general-purpose data buffering needs in industrial and consumer electronics.
Replacement Considerations
Check for direct pin-compatible substitutes within the 72V series. Verify if alternative manufacturers offer equivalent 18-bit, 2K-depth synchronous FIFOs with matching electrical characteristics.
