Specialized ICS Procurement Notes

Verify the specific suffix ETN against official documentation to confirm package type and tape/reel configuration. Confirm RoHS compliance status via the manufacturer's datasheet or ordering information section before procurement.

Specialized ICS Selection Notes

Ensure the design accommodates a 24MHz external crystal or clock source on HFXIN/HFXOUT. Select appropriate antenna matching components for the desired RF output power (up to 200mW). Verify that the host system can interface with either the UART or SPI protocol based on the PORTSLCT pin configuration.

Specialized ICS Part Context

This component belongs to the Analog Devices DeepCover family of embedded security solutions. It combines physical security layers with cryptographic processing to protect sensitive data and keys in contactless applications.

Specialized ICS Replacement Considerations

Consult the official datasheet for any listed alternative part numbers within the DeepCover series. Ensure any substitute maintains compatibility with ISO/IEC 14443 Type A and ISO/IEC 15693 protocols and supports the required SHA-3 engine functionality.

Specialized ICS FAQ

What are the supported communication standards?

The MAX66301 supports ISO/IEC 14443 Type A and ISO/IEC 15693 standards for contactless communication at 13.56MHz.

How is the sleep mode activated?

Sleep mode is activated by driving the SLEEP input pin low. The device exits this mode when the pin transitions high, resuming operation within 20ms.

What is the maximum RF output power?

The device can deliver up to 200mW of RF output power using both antenna drivers in parallel configuration.
