Microchip Technology PIC32CZ CA80/CA90 Microcontrollers

Microchip Technology PIC32CZ CA80/CA90 Microcontrollers are 32-bit high-performance MCUs based on an Arm^® Cortex^®-M7 processor. These MCUs offer up to 8MB of flash and 1MB of SRAM. The CA80/CA90 MCUs provide a wide range of connectivity options, including high-speed USB, CAN FD, SQI, SDHC, I²S™, Media LB™ bus, EBI, and SERCOM. These MCUs feature a Memory Protection Unit (MPU), clock failure detection with a fail-safe internal RC oscillator, and write protection on some peripherals. The PIC32CZ CA80/CA90 MCUs are available in 100-pin, 144-pin, 176-pin, and 208-pin TQFP and BGA packages.

The PIC32CZ CA90 MCUs feature an embedded Hardware Security Module (HSM) for developing secure applications. The HSM provides all the cryptographic hardware acceleration, key storage, and TRNG for implementing security functionality such as secure boot, TLS, and encryption/decryption. The PIC32CZ CA80 MCUs are designed to implement functionality and applications such as industrial gateways, graphics, and automotive applications.
