Tight security surrounds 32-bit MCUs

These mid-range MCUs are in stock at authorised distributor Mouser Electronics.

They combine connectivity, performance, and security options for Internet of Things (IoT), automotive, and communications applications.

This 32-bit microcontroller family includes the PIC32CK SG and PIC32CK GC MCUs.

Featuring a 120MHz Arm Cortex-M33 core, the 32-bit microcontrollers deliver up to 2 MBytes of flash memory and 512 KBytes of static random-access memory (SRAM).

Connectivity options include 10/100 Ethernet, high-speed USB, full-speed USB, CAN FD, and configurable serial communications for easy integration into wearables and sensor hubs, digital audio devices, IoT nodes, and more.

The PIC32CK family's analogue support features include a 32-channel peripheral touch controller and 12-bit ADC with sampling rates of up to 3 million samples per second.

Offering advanced key management, fast cryptographic operations, and authentication meet demanding industrial and medical applications.

An integrated Hardware Security Module (HSM) subsystem — with a dedicated CPU, memory, secure DMA controllers, cryptographic accelerators, and firewalled communications — forms a secure enclave for boot processes, software updates and running trusted applications.

Secure partitioning, enabled by TrustZone technology, provides an additional layer of protection for critical software functions.

The PIC32CK 32-bit microcontroller family is supported by the PIC32CK SG (EV33A17A) and PIC32CK GC (EV33A17A) Curiosity Ultra development boards.

The development boards include an onboard debugger, Arduino Uno R3 compatible interface, motor control interface, and an Xplained Pro extension compatible interface.
