Powered by an Arm Cortex-M33 core, Microchip’s PIC32CK 32-bit MCUs leverage both a hardware security module (HSM) and Arm’s TrustZone security architecture. This level of embedded security enables designers to meet upcoming cybersecurity compliance requirements set to take effect in 2024 for most IoT-connected devices.
The HSM subsystem of these mid-range MCUs integrates a dedicated CPU, memory, secure DMA controllers, cryptographic accelerators, and firewalled communications with the host. It provides symmetric and asymmetric cryptographic operations, true random number generation, key management, and authentication for automotive, industrial, medical, and communication applications. TrustZone, a hardware-based secure privilege environment, provides an additional layer of protection for key software functions.
PIC32CK microcontrollers support ISO 26262 function safety and ISO/SAE 21434 cybersecurity standards. Devices offer a range of options to tune the level of security, memory, and connectivity bandwidth. They furnish up to 2 Mbytes of dual-panel flash with ECC and 512 kbytes of SRAM. Connectivity options include 10/100-Mbps Ethernet, CAN FD, and USB.
The PIC32CK family is available now for purchase in high-volume production quantities.
