MCU Family Serves Up Ultra-Low Power Functionality

STMicroelectronics has released its STM32L0x0 Value Line microcontrollers that provide an additional, low-cost entry point to the STM32L0 series The MCUs embed the Arm Cortex -M0+ core. With up to 128 KB flash memory, 20 KB SRAM and 512 byte true embedded EEPROM on-chip the MCUs save external components to cut down on board space and BOM cost. In addition to price-sensitive and space-constrained consumer devices such as fitness trackers, computer or gaming accessories and remotes, the new STM32L0x0 Value Line MCUs are well suited for personal medical devices, industrial sensors, and IoT devices such as building controls, weather stations, smart locks, smoke detectors or fire alarms.
The devices leverage ST’s power-saving low-leakage process technology and device features such as a low-power UART, low-power timer, 41µA 10 ksample/s ADC and wake-up from power saving in as little as 5µs. Designers can use these devices to achieve goals such as extending battery runtime without sacrificing product features, increasing wireless mobility, or endowing devices like smart meters or IoT sensors with up to 10-year battery-life leveraging the ultra-frugal 670 nA power-down current with RTC and RAM retention.

The Keil MDK-ARM professional IDE supports STM32L0x0 devices free of charge, and the STM32CubeMX configuration-code generator provides easy-to-use design analysis including a power-consumption calculator. A compatible Nucleo-64 development board (NUCLEO-L010RB) with Hardware Abstraction Layer (HAL) library is already available, to facilitate fast project startup.

The STM32L0x0 Value Line comprises six new parts, giving a choice of 16- KB, 64- KB, or 128- KB of flash memory, 128-byte, 256-byte or 512-byte EEPROM, and various package options. In addition, pin-compatibility with the full STM32 family of more than 800 part numbers offering a wide variety of core performance and integrated features, allows design flexibility and future scalability, with the freedom to leverage existing investment in code, documentation and tools.

STM32L0x0 Value Line microcontrollers are in production now, priced from $0.44 with 16-KB of flash memory and 128-byte EEPROM, for orders of 10,000 pieces. The unit price starting at $0.32 is available for high-volume orders.

App Interfaces to Remote IoT Devices

PTC has announced the launch of the ThingWorx Asset Advisor app for service to accelerate its customers’ service transformation initiatives. ThingWorx Asset Advisor for service enables remote monitoring and servicing of assets deployed in the field. Built on PTC’s leading ThingWorx industrial innovation platform, ThingWorx Asset Advisor for service is a role-based app for service managers and technicians that is fast to deploy, scalable, flexible and customizable.

The app provides visibility to connected assets with key role-intelligent information, offering insight into the operating condition of the asset, alerts on operating anomalies and remote service for the connected assets. ThingWorx Asset Advisor for service follows PTC’s launch of the ThingWorx Asset Advisor app for manufacturing this past June at LiveWorx17 and continues PTC’s commitment to helping industrial companies simplify their digital transformation efforts.

TWXforServiceSG-1As industrial companies focus on improving efficiency and reducing downtime of their operations, being able to connect and monitor assets to capture critical alerts in real-time is key to an effective connected service strategy. PTC has a long history of enabling customers to connect assets and remotely monitor, diagnose, and resolve service issues. Customers adopting a connected service strategy helped PTC’s IoT business outpace the market growth rate of 30% to 40%in fiscal year 2017. Companies like Elekta, Diebold, Sysmex, and McKinley Elevator are improving first-time fix rates 30% more than industry averages; mean time to repair by 6X; and equipment uptime by 20%, by being able to remotely monitor and service connected assets. The ThingWorx Asset Advisor app enables customers to accelerate the time to value by providing them with an even easier and faster path to connected service capabilities.
