With the Cortex M4F processor, 256 kB RAM and the built-in 1 MB flash memory, the module can easily be used in standalone mode, thereby eliminating the need for an external processor, saving complexity, space, and cost. The rich set of security features from the ARM TrustZone security subsystem provide the necessary means for secure device operation in the IoT space. The PAN1780 module also supports Type 2 Near Field Communication for use in simplified pairing and payment solutions.
