Evaluation Kit for the MAXQ1850 and MAXQ1851 (MAXQ1851-KIT) (MAXQ1851-KIT)

The MAXQ1851 evaluation kit (EV kit) is a proven platform to conveniently evaluate the capabilities of the MAXQ1850 or the MAXQ1851 secure microcontrollers. The EV kit board features a socket for the target microcontroller, two smart card sockets, a PIN pad, and all the communication connectors needed to develop a financial terminal design. With the included software and a MAXQ® USB-to-JTAG/1-Wire adapter board, the EV kit also provides a complete, functional system ideal for software development and debugging of applications targeted for the MAXQ1850 or MAXQ1851. The MAXQ1850 and MAXQ1851 microcontrollers have similar features and are pin compatible. The MAXQ1851 has larger RAM memory size and secure nonvolatile AES key generation and storage.
