MAX66301ETN+

Specialized ICS Overview

The MAX66301ETN+ is a DeepCover secure authenticator integrating an RFID reader and SHA-3 coprocessor. It supports ISO/IEC 14443 Type A and ISO/IEC 15693 standards at 13.56MHz. The device features a 3.3V core with 5V-tolerant I/O, operating between -40°C and +85°C. Key electrical parameters include a typical supply current of 12mA at 3.3V and up to 20mA at 5.0V. It provides four 32-byte user memory pages, a 76-byte scratchpad, and a unique 64-bit serial number.

• Authentication of Consumables (e.g., Ink Cartridges)
• Blood Glucose Meters/Monitors
• Handheld Reader Modules

Specialized ICS Procurement Notes

Verify the package type matches the 56-TQFN (8x8mm) specification. Confirm that the ordering suffix corresponds to the tray packaging format indicated in local product fields. Ensure compatibility with 3.3V or 5V supply voltages for the analog front-end and digital I/O.

Specialized ICS Selection Notes

Select this component for applications requiring integrated contactless authentication and cryptographic processing. Ensure the design accommodates the 24MHz external crystal requirement for the system clock. Verify antenna driver configurations (single vs. parallel) based on required RF output power levels up to 200mW.

Specialized ICS Part Context

The MAX66301 belongs to the Maxim Integrated DeepCover family of embedded security solutions. It combines physical security layers with cryptographic functions to protect sensitive data. This specific model integrates the RFID reader directly with the authenticator coprocessor to simplify host processor interfaces.
