Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required packages and temperature grades. Confirm that the component meets all relevant regulatory standards for the intended deployment region. Cross-reference the datasheet revision history for any updates regarding pinout or electrical characteristics prior to finalizing procurement orders.
Selection Notes
Select this component when system design requires integrated LCD driving capabilities alongside cryptographic security functions. Consider the available GPIO count and peripheral set relative to application complexity. Evaluate the trade-off between processing speed and power consumption using the configurable voltage scaling features provided by the picoPower architecture.
Part Context
This part belongs to the SAM4L series of low-power microcontrollers manufactured by Microchip Technology. The series is designed for applications demanding high performance combined with minimal energy usage. The ATSAM4LC variant specifically distinguishes itself within the family by including advanced security modules and display controllers not present in other sub-series.
Replacement Considerations
Consult official substitution lists for compatible parts within the SAM4L family. Verify pin compatibility and memory configurations before replacing existing components in established designs.
