LX7201-15ISF

Overview

The LX7201-15ISF is an asynchronous FIFO memory device manufactured by Microsemi Corporation. It features a storage organization of 512 words by 9 bits, providing a total capacity of 4.5 Kbits. The component supports a maximum clock frequency of 40 MHz with a typical access time of 15 ns. It operates on a single 5 V power supply and utilizes CMOS technology for low power consumption. The device is housed in a 28-pin Plastic Dual In-line Package (PDIP) suitable for through-hole mounting applications.

Feature Summary

• Asynchronous operation allows independent read and write clock domains without synchronization requirements.
• CMOS technology ensures low power dissipation and high noise immunity during data transfer.
• Standard 5 V logic compatibility simplifies integration into existing digital systems.

Applications

• Data buffering between microprocessors and peripheral devices
• Level shifting between different voltage domains
• Clock domain crossing in asynchronous communication interfaces

Procurement Notes

Verify the specific suffix ISF to confirm package type and temperature range. Confirm end-of-life status as this part number may be discontinued. Request manufacturer documentation for pinout and electrical characteristics before finalizing design implementation.

Selection Notes

Select this component when asynchronous FIFO functionality is required with 512x9 depth. Ensure the system accommodates the 28-pin PDIP footprint. Verify that 15 ns access time meets the timing constraints of the target application interface.

Part Context

This part belongs to the LX7201 series of asynchronous FIFOs. It shares functional similarities with other members of the family but differs in package configuration and specific speed grades. The LX7201 designation indicates the base architecture and organization common across the series variants.

Replacement Considerations

Check for direct replacements within the same product family. Consider equivalent parts from other manufacturers offering similar 512x9 asynchronous FIFO specifications. Verify pin compatibility and electrical parameters before substitution.
