This feature is necessary for home appliances, industrial and automotive applications where the touch must work in a variety of harsh environments. To support developers with implementation, the PIC32CM JH comes with functional safety collateral such as a safety manual, Failure Modes Effects and Diagnostic Analysis (FMEDA) and diagnostic code targeting ISO 26262 ASIL B (Automotive Safety Integrity Level) safety levels.Īdditionally, the PIC32CM JH includes advanced touch with Driven Shield Plus, providing noise and water tolerant operability.

MBIST is the industry-standard method of testing embedded memories and can quickly test the integrity of the Static Random-Access Memory (SRAM) to ensure it is functioning properly before the code is run to mitigate failures. Other hardware features included on the PIC32CM JH MCU are Error Correction Code (ECC) with fault injection, loopbacks on the communications interfaces, system memory protection unit and MBIST, all of which are safety mechanisms used to meet ISO 26262 and IEC 60730 standards. It authenticates the code to make sure it is valid and prevents malicious code from being loaded onto the MCU. The TA100 employs ultra-secure hardware-based cryptographic key storage and cryptographic countermeasures to eliminate potential backdoors linked to software weaknesses. The PIC32CM JH, when paired with one of Microchip’s Trust Anchor TA100 CryptoAutomotive ™ security ICs, is compliant to ISO/SAE 21434, the new Cybersecurity Standard for Automotive. When using AUTOSAR, Microchip offers ASIL B microcontroller abstraction layers (MCALs) for functional safety applications - providing the lower-level hardware interface to the MCU.Īutomotive industry OEMs require both functional safety and cybersecurity protection for many in-vehicle applications including touch buttons and touch wheels, door controls and console controls, and body applications such as Advanced Driver Assistance Systems (ADAS). AUTOSAR-ready is designed to streamline the development process and reduce overall costs. The PIC32CM JH is compatible with AUTOSAR, an open software architecture, providing suppliers with the ability to change to lower-level hardware but keep the original application code, making it easier to migrate between different designs.
