That’s just two clicks and your project is half-way done. Go ahead and play with a few ideas right away.

Programming. Clicker 2 for CEC1702 is shipped without the Bootloader and the appropriate eFUSE settings (factory default). To be able to program clicker 2 for CEC1702 follow the steps explained on CEC1702 Specifics in the Help section of the ARM compilers, under "OTP Programming the CEC1702 device". You can download the Bootloader from the link.

Power Management. Clicker 2 for CEC1702 features LTC®3586, a highly integrated power management and battery charger IC that includes a current limited switching PowerPath manager. LTC®3586 also enables battery charging over a USB connection. You can supply power to the board with a micro USB cable provided in the package. On-board voltage regulators provide the appropriate voltage levels to each component on the board.

Strong cryptographic support

The CEC1702 provides a high level of security features, it's a microcontroller with a complete hardware cryptography-enabled solution. It delivers a multi-dimensional defense against attacks, including:

• Pre-boot authentication of system firmware: Providing an immutable identity and a root of trust to ensure that the firmware is untouched and hasn’t been corrupted.
• Firmware update authentication: Verifying that the firmware update has not been corrupted and is from a trusted source.
• Authentication of system critical commands: Attesting that any system-critical command is from a known source with authorization to make the given change, preventing potentially devastating actions.
• Protection of secrets with encryption: Safeguarding code and data to prevent theft or malicious activities.

CEC1702 microcontroller

The CEC1702 is a full-featured ARM® Cortex®-M7-based microcontroller with a complete hardware cryptography-enabled solution in a single package. This low-power but powerful, programmable 32-bit microcontroller offers easy-to-use encryption, authentication, private and public key capabilities and allows customer programming flexibility to minimize customer risk.
