  • I agree on the importance of matching the features with the requirements. I work with payment terminals and PIN pads and a key factor is security. We have to comply with a lot of security standards dictated by the PCI Security Standards Council and EMVCo so we require the microcontroller to have system level protection with secure boot loader, cryptographic hardware accelerators with hardware real random number generator, secure keyboard controllers, fault detection and external tamper sensors, battery backup for key storage, real time clock...interfaces for ISO 7816, NFC and magnetic stripe head. The MAX32555 DeepCover Secure Arm Cortex-M3 Flash Microcontroller is a good candidate.


    For the projects that I carry out as a hobbyist, the most important thing for me is that the development tools are free without any additional license cost.
