Microcontrollers Procurement Notes

Verify the specific suffix 'CDW' against official NXP documentation to confirm package dimensions and thermal characteristics. Confirm RoHS compliance status as manufacturing sources may vary. Check for end-of-life notices or obsolescence warnings from authorized distributors before procurement planning.

Microcontrollers Selection Notes

Select this component when an 8-bit architecture suffices for logic processing and minimal RAM is required. Ensure the design accommodates the 16-pin SOIC footprint and validates the 2.7V to 5.5V supply rail compatibility. Verify that the internal oscillator meets timing accuracy requirements without external crystals.

Microcontrollers Part Context

This part belongs to the Motorola HC08 family of 8-bit microcontrollers. It shares architectural similarities with other KX series devices but differs in memory size and peripheral configurations. The HC08 line was widely adopted for cost-sensitive embedded applications prior to newer generation transitions.

Microcontrollers Replacement Considerations

Consult official cross-reference guides for direct pin-compatible alternatives within the NXP portfolio. Verify electrical specifications and software compatibility if substituting with similar 8-bit MCUs from other manufacturers.
