MH1701 is a 32-bit low-power dual-interface microcontroller that supports various symmetric and asymmetric encryption functions, features low cost, high performance, and high security.
The contactless part complies with ISO/IEC14443 Type A standard and the contact part complies with ISO/IEC7816 standard. With built-in full hardware DES/TDES/AES/RSA/SHA, MH1701 has higher encryption performance. In addition to the ISO/IEC7816 interface, MH1701 also has 8 GPIOs (multiplexed with SPIM/SPIS/IIC), which can be applied to a variety of IoT security scenarios.
