Microchip Technology announces the PIC32CM JH microcontroller (MCU) to provide manufacturers with an MCU solution equipped with components that meet ISO 26262 and ISO/SAE 21434 functional safety standards.

Manufacturers of electronic systems, from vehicles to home appliances, are moving toward automating and connecting end-applications, spurring the need for industry standards related to functional safety and cy bersecurity to ensure that their products operate safely and securely.

The PIC32CM JH microcontroller is a 512KB Flash, 5V, Dual CAN FD device that offers premium features generally available only on more expensive and higher performance devices.

This is the industry's first MCU based on the Arm Cortex-M0+ architecture with AUTOSAR, Memory-Built-In Self-Test (MBIST) and secure boot support.

The PIC32CM JH is compatible with AUTOSAR, an open software architecture, which offers vendors the ability to upgrade to lower-level hardware while retaining the original application code, facilitating migration between different projects.

AUTOSAR-ready is designed to simplify the development process and reduce overall costs.

When using AUTOSAR, Microchip offers microcontroller abstraction layers (MCALs) ASIL B for functional safety applications, providing the lower-level hardware interface to MCUs.

Automotive OEMs require both functional safety and cybersecurity for many in-vehicle applications, such as touch buttons and touch knobs, door controls and console controls, and applications such as ADAS (Advanced Driver Assistance Systems).

The PIC32CM JH, when combined with one of Microchip's Trust Anchor TA100 CryptoAutomotive security ICs, iscompliant with ISO/SAE 21434, the new cybersecurity standard for the automotive industry.

The TA100 uses hardware-based ultra-secure cryptographic key storage and cryptographic countermeasures to eliminate potential backdoors related to software weaknesses.

Secure boot is part of the hardware and authenticates the code to make sure it is valid and prevents malicious code from being loaded into the MCU. Other hardware features included in the PIC32CM JH MCU are ECCs (Error Correction Code) with fault injection, loopbacks on communication interfaces, system memory protection units and MBIST, all security mechanisms used to meet ISO 26262, IEC 61508 and IEC 60730 standards.

MBIST is the industry-standard method for testing embedded memories and can quickly check the integrity of SRAM (Static Random-Access Memory) to make sure it is working properly before code is executed to mitigate errors.

To support developers in implementation, PIC32CM JH comes with functional safety documentation such as a safety manual, Failure Modes Effects and Diagnostic Analysis (FMEDA), and diagnostic code at ISO 26262 ASIL B (Automotive Safety Integrity Level) safety levels.

In addition, the PIC32CM JHincludes advanced touch control with Driven Shield Plus, which provides noise and water-resistant operation. This feature is necessary for home appliances, industrial and automotive applications where touch must operate in a variety of harsh environments.

PIC32CM JH MCU is supported by the PIC32CM JH01 Curiosity Pro Development Kit.

Comments

"With the PIC32CM JH MCU, Microchip is addressing the growing need for microcontroller solutions designed with functional safety and cybersecurity protection in mind, which is especially important in the automotive industry," said Rod Drake, vice president of Microchip Technology's 32-bit MCU business unit. "OEMsand other manufacturers now have the ability to use an entry-level Arm Cortex-M0+-based MCU to meet compliance requirements previously available only on high-end MCUs."
