Microchip Functional Safety Ready Portfolio

Functional safety ICs ease compliance with ISO 26262 and other standards

Microchip supplies a broad portfolio of products designated as ‘Functional Safety Ready’, giving OEMs confidence that they can comply with the strict requirements of safety protocols such as the automotive industry’s ISO 26262 standard when deploying Microchip products in new designs.

In applications such as appliances, industrial control systems and vehicles, designers are increasingly relying on electronics systems to provide efficient control and enhanced user features. These applications require safe and reliable operation to protect the well-being of end users. Most of the time, electrical systems operate as intended, but in the event of unexpected conditions or a system malfunction, the application of functional safety specifications such as ISO 26262 ensures that manufacturers have designed their products to operate safely.

The Microchip range of Functional Safety Ready products includes microcontrollers ranging from 8-Bit to 32-Bit as well as MPUs, Digital Signal Controllers (DSCs), and interface and connectivity solutions such as CAN controllers. Products which carry the Functional Safety Ready designation offer the latest hardware safety features, and are supported by detailed documentation and other collateral. A Failure Modes, Effects, and Diagnostic Analysis (FMEDA) report, for instance, quantifies the rate of failure events for each of a device’s fault modes. This information is presented as a Failure In Time (FIT) rate distribution.

The features of the Functional Safety Ready products help OEMs to gain certification for compliance with standards including:

  • ISO 26262, applied to safety-related systems which include one or more electrical and/or electronic systems and which are installed in series production passenger cars
  • IEC 61508, for those parts of a device or system which perform automated safety functions, including sensors, control logic, actuators and microprocessors. The standard is applied across various industry sectors.
  • IEC 60730, applied to automatic electrical controls for use in, on, or in association with equipment for household and similar use
  • IEC 62304, which defines the life cycle requirements for medical device software

These standards support multiple levels of safety analysis and protection measures, which are applied depending on the likelihood and severity of the hazard. The methods of addressing hazards range from detecting single failures and putting the system into a safe state, to full redundancy, which ensures that failures are not only detected but also corrected without any interruption or degradation of service. Microchip Functional Safety Ready products are available to meet the requirements of any of the specified safety levels.
