Industrial and consumer application designers must consider implementing security functionality in their devices during the development process as security threats evolve and become more sophisticated. To allow designers to easily integrate security into their applications, Microchip Technology announces 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 new family 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. The HSM 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 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 onboard Flash, 1 MB of SRAM, and Error Correction Code (ECC) memory to mitigate data corruption.

 

The PIC32CZ CA devices are the latest 32-bit MCUs to join Microchip’s broad portfolio of PIC32 and SAM families that provide high-performance, functional capabilities, and many features to customize and create innovative products.  

 

The devices 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 is available for $14.80 each in 10,000-unit quantities and the PIC32CZ CA90 is available for $15.54 each in 10,000-unit quantities in a BGA 208 package.
