Procurement Notes

Verify component authenticity through authorized NXP distributors or certified suppliers. Confirm the specific suffix 'CLH' matches the required 64-LQFP package and industrial temperature grade. Check for RoHS compliance documentation relevant to the manufacturing batch. Ensure the part status is reviewed, as availability may vary due to lifecycle changes.

Selection Notes

Select this MCU when 16-bit ADC resolution is critical for sensor interfacing. The S08 core offers efficient code density for cost-sensitive applications. Verify that the 1.8V to 3.6V supply range aligns with system power rails. Consider the 64-pin count to ensure sufficient I/O allocation for the target design without excessive pin sharing.

Part Context

This component belongs to the NXP S08 series of 8-bit microcontrollers, designed for general-purpose and automotive applications. The GW variant specifically targets cost-effective solutions with enhanced connectivity features like LINbus. It shares architectural similarities with other S08 members but distinguishes itself through its specific memory configuration and peripheral set.

Replacement Considerations

Consult official NXP cross-reference guides for verified substitutes. Potential alternatives within the S08 family may include variants with different memory sizes or package types. Ensure any replacement maintains compatibility with the 64-LQFP footprint and electrical specifications if pin-for-pin substitution is required.
