| X-Ware IoT Platform Integrates STM32 MCU Firmware Update Express Logic has announced that it has integrated the STMicroelectronics' Secure Boot and Secure Firmware Update v.2.0 services with its X-Ware IoT Platform for its developers using the STMicroelectronics' STM32-family of ARM Cortex-M microcontrollers.
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.

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.

MCU-Based Blood Pressure Monitoring Eval Kit
Renesas Electronics has announced an expansion of its healthcare solution lineup with the launch of a new blood pressure monitoring evaluation kit. The new blood pressure monitoring evaluation kit comprises hardware and software elements needed to jump start blood pressure measurement design. The kit includes a pressure sensor, arm cuff, pump, electronically controlled valve, LCD panel and a reference board. The reference board incorporates an RL78 MCU-based ASSP (application specific standard product) that includes analog functions required for blood pressure measurement. Reference software and graphical user interface (GUI) development tool are also part of the new evaluation kit. Using the new evaluation kit, system manufacturers can immediately begin their system evaluations and significantly reduce their development time.
The Internet of Things offers consumers connected tools with which to manage their personal healthcare more efficiently. For instance, blood pressure monitors are already popular personal medical devices and the market is expected to grow further as blood pressure monitoring functions are incorporated into wearable devices. The growth of this market offers new business opportunities, but can also be challenging, particularly for system manufacturers who are new to the connected healthcare device ecosystem and may not have the built-in application-specific expertise. Blood pressure measurement requires a specific expertise, including filtering functions for extracting the wave forms required for measurement, making it extremely time consuming to start studying this area from the very beginning.
Renesas has developed the new blood pressure monitoring evaluation kit to alleviate the development pain points, providing functions close to those used in actual blood pressure monitors. This helps accelerate blood pressure measurement system development. CONTINUE READING

SST and UMC Qualify Flash Tech on 40-nm Process
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.
The high endurance of embedded SuperFlash IP offers System on a Chip (SoC) customers extensive reliability and design flexibility combined with reduced power usage. SST's SuperFlash non-volatile memory technology is qualified for a minimum of 100,000 cycles, underscoring the technology's reliability. Ideal for edge computing in IoT devices, SST embedded SuperFlash technology features power benefits that derive from low-power standby and read operations, with core supply as low as 0.81 V. SuperFlash also secures applications with code maintained on chip, which is the first step in preventing illegal access through hardware and software attacks. 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.

Software Speeds Safety Certification for STM32-Based Systems
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.
