72240L10TPG

Overview

The Renesas Electronics Corporation 72240L10TPG is a synchronous FIFO memory device belonging to the 7200 series. It features an 8K storage capacity organized as 1K words by 8 bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and a typical access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 40mA. The device is housed in a 28-pin plastic dual in-line package (PDIP) designed for through-hole mounting and functions reliably across an industrial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with independent read and write clock controls
• Unidirectional data bus architecture for dedicated input/output flow
• Zero fall-through time output enable capability
• Status flag signaling for empty and full conditions

Applications

• Graphics data buffering systems
• Local Area Network (LAN) interface modules
• Interprocessor communication links

Procurement Notes

Verify the specific suffix 'TPG' against official manufacturer documentation to confirm lead-free status and RoHS3 compliance. Confirm the exact package dimensions match the 28-PDIP specification. Check for any Product Change Notifications regarding label changes or assembly site updates. Ensure the operating environment stays within the specified 0°C to 70°C range. Validate that the 4.5V to 5.5V supply voltage aligns with system power rails.

Selection Notes

Select this component when a synchronous FIFO with 8K depth and 8-bit width is required. It is suitable for applications needing 100MHz throughput with low latency. Consider the 28-PDIP package if through-hole mounting is necessary. Verify compatibility with 5V logic levels. Evaluate if unidirectional data flow meets the system design requirements compared to bidirectional alternatives.

Part Context

This part belongs to the Renesas 7200 series of SyncFIFO devices. These components are designed for high-speed data buffering between asynchronous or synchronous domains. The 72240 variant specifically provides 8K x 8 organization. The series is known for zero fall-through architecture and flexible clocking options. It serves as a standard solution for temporary data storage in digital signal processing and communication interfaces.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the same series. Verify electrical parameters such as access time and voltage ranges before substitution. Check for updated package options if availability is limited.
