EYE on NPI: STSAFE chip collection from ST
This week's EYE ON NPI takes a closer look at security! The STSAFE chip collection from ST (https://www.digikey.com/product-detail/en/stmicroelectronics/X-NUCLEO-SAFEA1A/497-X-NUCLEO-SAFEA1A-ND/11568322) is a super easy and inexpensive way to add hardened security to your project - giving you a lot of flexibility when deciding on core chipsets. Why is a separate chip important? Microcontrollers often store their code in flash memory, so even if you hard-code authentication keys in flash or EEPROM, it can be read out by dumping the firmware. Yes, even if you have a chip that has…
