72235L15JI

Overview

The Renesas Electronics Corporation 72235L15JI is a synchronous FIFO memory IC belonging to the 7200 series. It features a storage capacity of 36K bits, organized as 2K words by 18 bits. The device supports unidirectional bus operation with an I/O frequency of up to 66 MHz and a maximum access time of 10 ns. It operates on a single 5.0 V core voltage supply within a 4.5 V to 5.5 V range, drawing a maximum supply current of 60 mA. The component is housed in a 68-pin PLCC package with dimensions of 24.0 x 24.0 mm and a pitch of 1.27 mm. It functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Provides efficient data buffering through synchronous first-in, first-out memory architecture
• Supports high-speed data transfer with 66 MHz I/O frequency capability
• Features programmable status flags for custom operational monitoring
• Utilizes a standard 5.0 V TTL interface for system compatibility

Applications

• Data buffering between asynchronous clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify component authenticity and datasheet alignment due to obsolete status. Confirm package type matches design requirements, as variants exist. Check for lead-free compliance if required by project specifications. Ensure availability from authorized sources given discontinuation notices. Validate temperature ratings against environmental conditions.

Selection Notes

Select this part for applications requiring 18-bit wide synchronous FIFO buffering. Compare access times and frequencies against system timing constraints. Consider package availability and pinout compatibility during redesign. Evaluate alternative packages like TQFP if PLCC is unavailable. Verify power consumption limits fit thermal budgets.

Part Context

This component is part of the IDT/Renesas 72235LB family of synchronous FIFOs. It shares architectural similarities with other members like the 72235LB15PFGI8 but differs in package and specific electrical characteristics. The 72235 series is designed for high-performance data handling in embedded and industrial applications.
