100422FC10

Overview

The 100422FC10 is an asynchronous static random-access memory (SRAM) integrated circuit manufactured by Fairchild Semiconductor. It provides a storage capacity of 1 kilobit organized in parallel configuration. The device features a fast access time of 10 nanoseconds, ensuring rapid data retrieval for system applications. It is housed in a 24-lead CFlatPack package, which facilitates surface-mount integration into electronic circuits requiring compact memory solutions.

Feature Summary

• Asynchronous operation for flexible interface timing
• Parallel data bus architecture for direct connectivity
• Compact surface-mount packaging for space-constrained designs

Applications

• Embedded systems requiring non-volatile or volatile backup memory
• Industrial control units with parallel interface requirements
• Consumer electronics utilizing compact SRAM modules

Procurement Notes

Verify the manufacturer origin and lot traceability when sourcing this component, as it may be available through marketplace distributors rather than direct factory channels. Confirm RoHS compliance status and lead-free specifications against current regulatory requirements. Ensure the 24-CFlatPack package condition matches your assembly needs. Cross-reference the part number with official Fairchild or onsemi documentation to confirm functional equivalence before procurement.

Selection Notes

Select this component when a small-capacity, high-speed parallel SRAM is required for asynchronous logic interfaces. The 10 ns access time suits applications demanding quick data turnover without complex clock synchronization. The CFlatPack package is suitable for automated surface-mount assembly processes. Consider pin compatibility and voltage levels if replacing existing designs.

Part Context

Fairchild Semiconductor, now part of onsemi, specializes in power management and sensing technologies. This SRAM belongs to their legacy discrete memory product line, designed for straightforward parallel interfacing in industrial and consumer electronics. The 100422FC10 represents a standard solution for low-density memory needs in established hardware architectures.

Replacement Considerations

Check for equivalents from onsemi or other manufacturers offering 1Kbit parallel SRAM in 24-pin flat packages. Verify electrical parameters such as access time and supply voltage match the original design specifications.
