72241L25PF

Overview

The Renesas 72241L25PF is a synchronous First-In, First-Out (FIFO) memory device featuring a storage capacity of 36K organized as 4096 words by 9 bits. It operates with a maximum data rate of 100MHz and an access time of 6.5ns. The component supports unidirectional bus communication and functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 35mA. Designed for surface-mount installation, it is housed in a 32-pin PLCC package measuring 14mm by 11.46mm. The device includes programmable flags and operates reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous FIFO architecture with independent read and write clock controls
• Programmable Almost-Empty and Almost-Full status flags
• Zero fall-through time design for immediate data availability
• Output enable pin for high-impedance state control

Applications

• Graphics data buffering systems
• Local area network interface buffers
• Interprocessor communication links

Procurement Notes

Verify the specific suffix 'PF' against official Renesas documentation to confirm the exact package type and lead finish specifications. Ensure that the operating environment remains within the specified 0°C to 70°C commercial temperature range. Confirm that the 4.5V to 5.5V power supply requirements align with the target system design before integration.

Selection Notes

Select this component when a synchronous FIFO with 9-bit word width and 4K depth is required. It is suitable for applications needing 100MHz throughput capabilities. Consider the 32-pin PLCC package constraints for PCB layout. Verify compatibility with the system's voltage levels and timing requirements relative to the 6.5ns access speed.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs. The series provides various configurations for data buffering needs. The 72241 variant specifically offers 36K capacity. This family is designed for high-speed data transfer between asynchronous or synchronous domains in digital systems.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference technical parameters such as access time, capacity, and package dimensions to ensure functional equivalence.
