Overview
The Renesas Electronics Corporation 72235L10J is a synchronous First-In, First-Out (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 operates with a maximum data rate of 100MHz and an access time of 6.5ns. It supports unidirectional bus architecture and includes programmable status flags. The device functions within a supply voltage range of 4.5V to 5.5V and utilizes a PLCC-68 package.
Feature Summary
- Synchronous FIFO architecture for reliable data buffering
- High-speed operation supporting up to 100MHz data rates
- Programmable status flags for flow control management
Applications
- Data buffering in high-speed digital systems
- Interface bridging between asynchronous logic blocks
- Rate matching in telecommunications equipment
Procurement Notes
Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for end-of-life notices or obsolescence warnings from the manufacturer. Ensure packaging specifications match production line handling capabilities. Validate pin compatibility with existing PCB footprints.
Selection Notes
Select this component when synchronous FIFO functionality with 18-bit word width is required. Consider the 6.5ns access time for timing-critical applications. Evaluate the PLCC-68 package suitability for the target enclosure. Compare power consumption against system thermal limits. Verify that the 4.5V to 5.5V operating range aligns with available power rails.
Part Context
This part belongs to the Renesas 7200 series of high-performance FIFO memories. The series offers various configurations differing in speed grades, word widths, and package types. The 72235 variant specifically provides 2K x 18 organization. Other family members include variants with different access times and pin counts.
Replacement Considerations
Check for direct cross-reference part numbers from IDT or Microsemi. Verify functional equivalence regarding pinout and electrical characteristics. Review updated datasheets for any feature changes in successor models.
