Microchip’s Wi-Fi SDK combines hardware cryptography suites within the CEC1702, a full-featured ARM Cortex-M4-based microcontroller (MCU), with the industry-proven WINC1510, a low-power 802.11 b/g/n certified Wi-Fi module.
The hardware-based security engines within the Wi-Fi HomeKit solution greatly reduce system calculation times, resulting in a fast and friendly end-user experience. With the dramatic reduction in execution time for HomeKit commands such as pairing, with pair setup in 0.95 seconds and pair verify in less than one tenth of a second, system reaction is accelerated for seamless consumer experiences such as instantly unlocking a front door. This reduced time of system activity enabled by the Wi-Fi SDK results in lower system power consumption.
The CEC1702 programmable 32-bit MCU offers security measures such as secure boot which allows equipment manufacturers to establish a hardware-based root of trust to protect against a security breach. Developers can also leverage integrated security features such as easy-to-use encryption, authentication, private and public key capabilities and customer programming flexibility to minimise application risk. Additionally, the CEC1702 features 480 KB SRAM code plus data, which gives developers ample code space for the HomeKit protocol as well as their application-specific code.
