72241L10JG

Overview

The Renesas Electronics Corporation 72241L10JG is a synchronous FIFO memory device with a storage capacity of 36k bits, organized as 4K words by 9 bits. It supports unidirectional data transfer at a maximum clock frequency of 100 MHz and features an access time of 6.5 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum current of 35 mA. It is housed in a 32-pin PLCC package (14x11.46 mm) designed for surface mount installation and functions reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous architecture with independent read and write clocks supporting dual-clock operation
• Zero fall-through time design ensuring immediate data availability upon valid read commands
• Programmable Almost-Empty and Almost-Full flags for precise buffer level monitoring
• Output enable control placing the output data bus into a high-impedance state

Applications

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

Procurement Notes

Verify the specific suffix JG confirms the 32-pin PLCC package variant when sourcing. Confirm RoHS compliance status and lead-free designation against the latest manufacturer documentation. Check for moisture sensitivity levels and recommended storage conditions prior to assembly. Ensure the intended application environment remains within the specified 0°C to 70°C operating temperature range for reliable performance.

Selection Notes

Select this component for applications requiring a 9-bit wide synchronous FIFO with 4K depth. Consider the 6.5 ns access time and 100 MHz speed for high-speed data buffering needs. Verify that the 32-pin PLCC package fits the target PCB layout constraints. Ensure the system power supply maintains the required 4.5 V to 5.5 V range for proper logic operation.
