Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'SZ' against the official datasheet to confirm the operating temperature range and package details, as variations within the MEC1428 family may differ. Ensure compatibility with MPLAB development tools for firmware implementation. Confirm pin-out alignment if migrating from legacy LPC-based designs to ensure seamless integration.

Application Specific Microcontrollers Selection Notes

Select the MEC1428-SZ-C1 when an eSPI or LPC interface is required alongside 192 KB of on-chip SRAM. This model offers 108 GPIOs and supports both 1.8V and 3.3V I/O levels. Verify that the 0°C to +70°C operating range meets system requirements, as other variants in the family may support extended industrial temperatures.

Application Specific Microcontrollers Part Context

This component belongs to the MEC14XX family of low-power embedded controllers designed for computing platforms. The family ensures pin compatibility across devices like the MEC1408 and MEC1418, facilitating easy migration from LPC to eSPI architectures while maintaining consistent software and hardware integration patterns.

Application Specific Microcontrollers Replacement Considerations

The MEC1418 is a pin-compatible alternative within the same family. Verify if the specific interface requirements (e.g., eSPI vs. LPC) and I/O voltage configurations match the application needs before substituting.
