ST has extended the STM32L4 technology providing more performance (up to 120 MHz), more embedded memory (up to 2 Mbytes of Flash memory and 640 Kbytes of SRAM) and richer graphics and connectivity features while keeping the best‐in‐class ultra‐low‐power capability.

The new STM32L4+ devices stretches performance to 150DMIPS (233 ULPMark-CP) at 120MHz — can act as the central controller in a full range of fitness bands, smart watches, small medical equipment, smart meters, smart industrial sensors and more. All these applications require sophisticated functions, instant responses, and minimal downtime for battery charging, making the ultra-efficient STM32L4+ an ideal fit.

  • What is ST’s market standing in the Microcontroller sector?

ST is leading the MCU innovation and is recognized by the industry and our customers as having one of the widest and most innovative portfolios of MCUs from ultra-low power to highest performance solutions. We are by far the market and technology leader in ARM Cortex-based MCUs with the widest range of products. STM32 portfolio alone offers 11 major product series (F0, F1, F2, F3, F4, F7, L0, L1, L4, H7, L4+) and more than 800 part numbers. ST has surpassed 2 billion unit sales of its STM32 microcontrollers. ST also crossed three billion unit sales of its robust and versatile STM8 microcontrollers. To date, we have delivered over 1 Million development kits for STM32 and STM8 family

  • What is unique about STM32 series?

STM32 is the brain of IoT applications. The broad portfolio serves many applications and provide more flexibility, more efficiency, more processing power and lower consumption. STM32 powers scalable security solutions for ultra-low power and high performance platforms, providing protection against hardware and software attacks, which are mandatory in a smarter connected world.

  • What is the objective of participation at IOTSHOW.IN

One of the key objective was to introduce the new STM32L4+ series MCUs and make it easy for customers to rapidly evaluate, prototype and commercialize Smart Things and innovative new IoT applications. ST has a strong presence in mass market and a rich ecosystem to facilitate design-in & customer time to market.

  • Highlight the MCU demos displayed at ST booth at 2018

STM32L4+ Ultra-low power

STM32L4+ based demo showed TFT and Ultralow power capabilities of this recently launched family. STM32L4+ is another milestone in ultra low power market needs which has inbuilt graphics capabilities and high performance core running upto 120MHz (added). The STM32L4R9I-Discovery board is a complete demonstration and development platform for STMicroelectronics ARM® Cortex®-M4 core-based STM32L4R9AI Microcontroller.

LoRa Communication

LoRa, a wireless communication technology developed to create low-power, wide area networks (LPWAN) required for machine to machine (M2M) and Internet of Things (IoT) applications.  The demo included LoRa nodes based on ultra low power STM32L4 and LoRa gateway based on high performance STM32F7 working on public network available on Tata network. It showed the temperature, humidity and pressure information of the nodes with a friendly GUI

Power Shield

STM32 Power Shield demo is a programmable power supply source with advanced power consumption measurement capability powered by STM32L4 device (added). It performs consumption averaging (static measurement upto 200mA) as well as real time analysis (dynamic measurement upto 50mA).
