Highly configurable 32-Bit MCU features embedded hardware security module

1 min read

Microchip Technology has announced a new family of PIC32CZ CA 32-bit microcontrollers with a 300 MHz Arm Cortex-M7 processor, an integrated Hardware Security Module (HSM), and a wide range of connectivity and Flash memory options for added flexibility.

The MCUs are intended to enable industrial and consumer application designers, who must consider implementing security functionality in their devices during the development process as security threats evolve and become more sophisticated, to easily integrate security into their applications.

The portfolio of PIC32CZ CA devices includes the PIC32CZ CA90 with a HSM or the PIC32CZ CA80 without the integrated HSM. The HSM in the PIC32CZ CA90 is a monolithic solution that provides advanced security for industrial and consumer applications. It operates as a secure subsystem with a separate MCU on board that runs the firmware and security features including hardware secure boot, key storage, cryptographic acceleration, true random number generator and more.

For products that require added security, factory provisioning is available on the PIC32CZ CA90 which, upon completion, provides customers with pre-provisioned devices ready to be deployed. 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 PIC32CZ CA microcontrollers make it easier for our customers to implement embedded security features into their design,” said Rod Drake, corporate vice president of Microchip’s MCU32 business unit. “These are extremely versatile MCUs with the option of factory provisioning at low-volume production and other customizable configurations such as connectivity and memory to fit many different requirements.”

The PIC32CZ CA MCUs 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 2, 4 or 8 MB of on-board Flash, 1 MB of SRAM and Error Correction Code (ECC) memory to mitigate data corruption.
