| X-Ware IoT Platform Integrates STM32 MCU Firmware Update
The X-CUBE-SBSFU Secure Boot and Secure Firmware Update solution enables the update of the STM32 MCU built-in program with new firmware versions based on the X-Ware IoT Platform. The update process is performed in a secure way to prevent unauthorized updates and access to confidential on-device data. In addition, Secure Boot (Root of Trust services) checks and activates STM32 mechanisms, and checks the authenticity and integrity of X-Ware IoT Platform before every execution to ensure that invalid or malicious code cannot be run. Because X-CUBE-SBSFU is built on top of STM32Cube software technology, the X-Ware IoT Platform integration will be portable across the entire range of STM32 microcontrollers, beginning with the STM32L4 and STM32L4+ series devices. Express Logic considers itself a safety leader in the embedded IoT space with its industrial-grade approach, including pre-certification to SIL 4 and ASIL D safety standards. The new secure boot and secure firmware update services from STMicroelectronics enhance security for Express Logic's X-Ware IoT Platform for the STM32 microcontroller. Download Mentor's White Paper:
Discover Unknown PCB Design Issues with DRC This FREE white paper addresses several of the pervasive myths within the PCB verification market, such as the need for post-layout PCB verification on high-speed designs only. The paper also discusses how a designer can seamlessly integrate with the PCB design process to find issues that are often missed by current PCB verification methods.
Low-Power Microcontrollers Extend
Battery Life for Wearables
Maxim Integrated Products has introduced the ultra-low power MAX32660 and MAX32652 microcontrollers. These MCUs are based on the ARM Cortex-M4 with FPU processor and provide designers the means to develop advanced applications under restrictive power constraints. Maxim's family of DARWIN MCUs combine its wearable-grade power technology with the biggest embedded memories in their class and advanced embedded security. The MAX32660 (shown) offers designers access to enough memory to run some advanced algorithms and manage sensors (256 KB flash and 96 KB SRAM). They also offer excellent power performance (down to 50µW/MHz), small size (1.6 mm x 1.6 mm in WLP package) and a cost-effective price point. Engineers can now build more intelligent sensors and systems that are smaller and lower in cost, while also providing a longer battery life.
As IoT devices become more intelligent, they start requiring more memory and additional embedded processors which can each be very expensive and power hungry. The MAX32652 offers an alternative for designers who can benefit from the low power consumption of an embedded microcontroller with the capabilities of a higher powered applications processor.

Microchip Technology subsidiary Silicon Storage Technology (SST) and United Microelectronics Corporation (UMC) have announced the full qualification and availability of SST's embedded SuperFlash non-volatile memory on UMC's 40 nm CMOS platform. The 40-nm process features a more than 20 percent reduction in embedded Flash cell size and a 20- to 30-percent reduction in macro area over their 55-nm process.  SST's SuperFlash technology complements UMC's embedded memory portfolio with high density and low-power IP. Combined with SST's inherent technology reliability, UMC's flexible capacity and high-yield maturity for its 55-nm and 40-nm platform provides foundry customers the manufacturing support needed to build a range of product applications.
STMicroelectronics has announced new free software for its STM32 microcontrollers. The functional-safety design package cuts complexity and IEC 61508 safety-certification costs for STM32-based safety critical applications. This resource is created for designers of STM32-based devices in the field of industrial controls, robots, sensors, medical, or transportation, which must be certified up to Safety Integrity Level (SIL) 2 or 3 of the recognized safety standard IEC 61508. ST's STM32 SIL Functional-Safety Design Package simplifies system development and certification.  The SIL Functional-Safety Design Package comprises documentation and the X-CUBE-STL, a software Self-Test Library certified to IEC 61508 SIL3. The package is initially available for the STM32F0 series. ST will continue to introduce equivalent packages for all other series in the STM32 family throughout 2018 and 2019. There are currently more than 800 STM32 microcontroller variants. ST's STM32 SIL Functional Safety Design Package contains full documentation to support development of STM32-based embedded systems to meet IEC 61508 requirements for functional safety. The documentation comprises safety manuals that detail all applicable safety requirements, or conditions of use, with implementation guidelines to help developers certify their products to SIL 2 or SIL 3 in accordance with IEC 61508. Also included are the mandatory Failure-Modes Effects Analysis (FMEA), containing the detailed list of microcontroller failure modes and related mitigation measures, and Failure-Mode Effects and Diagnostics Analysis (FMEDA), which gives a static snapshot reporting IEC 61508 failure rates, computed at both the microcontroller and basic functions detail levels. |
