32-bit microcontroller safeguards industrial-consumer applications, says Microchip

Industrial and consumer application designers looking to implement security functionality in devices during the development process can employ Microchip Technology’s new family of PIC32CZ CA 32-bit microcontrollers.
They are equipped with a 300MHz Arm Cortex-M7 processor, an integrated hardware security module (HSM) and a range of connectivity and Flash memory options.
The PIC32CZ CA family includes the PIC32CZ CA90 with a HSM or the PIC32CZ CA80 without HSM. The HSM in the PIC32CZ CA90 is monolithic and provides advanced security for industrial and consumer applications, said Microchip. The HSM operates as a secure subsystem with a separate microcontroller on board that runs the firmware and security features including hardware secure boot, key storage, cryptographic acceleration and true random number generator.
For products that require added security, factory provisioning is available on the PIC32CZ CA90 which, upon completion, provides customers with pre-provisioned devices. Microchip’s Trust Platform development suite is an in-house secure provisioning tool that enables a secure supply chain channel at scale or in low-volume production.
The microcontrollers have the option of factory provisioning at low volume production and other customisable configurations such as connectivity and memory to fit many different requirements
The PIC32CZ CA microcontrollers can be configured using a wide range of connectivity options including USART/UART, I2C, SPI, CAN FD, High-Speed USB and Gigabit Ethernet. The Ethernet option includes audio video bridging (AVB) and precision time protocol (PTP) based on the IEEE 1588 standard. These devices are scalable with two, four or 8Mbyte of on-board flash, 1 Mbyte of SRAM and error correction code (ECC) memory to mitigate data corruption.
The PIC32CZ CA 32-bit microcontrollers are supported by the PIC32CZ CA90 Curiosity Ultra development board, the PIC32CZ CA80 Curiosity Ultra development board and MPLAB Harmony v3 to test, program and debug in the design phase.
The PIC32CZ CA80 and PIC32CZ CA90 are available in a BGA 208 package.
