Procurement Notes
Verify current availability status as this part may be subject to discontinuation notices. Confirm package type and suffix compatibility during sourcing. Check for relevant product change notifications or errata updates prior to final procurement decisions.
Selection Notes
Select this component for designs requiring integrated high-resolution ADCs within an 8-bit MCU ecosystem. Ensure voltage levels match the 1.8V to 3.6V operational range. Consider the 24-pin QSOP footprint for PCB layout constraints.
Part Context
This model belongs to the C8051F9xx series of ultra-low-power microcontrollers. It shares architectural similarities with other members like the C8051F989 and C8051F990, differing primarily in memory size and peripheral configurations. The series emphasizes energy efficiency with sleep modes down to 10 nA.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for potential end-of-life alternatives.
