Procurement Notes

Verify the specific suffix 'GMR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the active status aligns with long-term supply requirements, as availability may change. Ensure compatibility with existing design-in tools and debuggers such as the DEBUGADAPTER1-USB for development and validation phases.

Selection Notes

Select this model when 4KB of flash and 512 bytes of RAM are sufficient for application logic. The 24-pin QFN footprint is suitable for space-constrained designs. Consider alternative pin counts if more general-purpose I/O or additional peripherals are needed. Verify that the 1.8V to 3.6V supply range matches the system power architecture.

Part Context

This component belongs to the C8051F9xx family of mixed-signal microcontrollers. These devices integrate standard 8051 cores with extensive on-chip peripherals. The family shares common architectural features but varies in memory size, I/O count, and ADC resolution. This specific part offers a balance of processing capability and analog performance in a compact form factor.

Replacement Considerations

C8051F988-C-GMR is a documented variant within the same product line. Verify package and electrical specifications before substitution. Other members of the C8051F9xx series may serve as alternatives if memory or pin configurations differ.
