STMicroelectronics ultralowpower microcontroller EnergyLiteTM platform
STMicroelectronics has identified an optimal balance between high performance and ultralow power, through different modes, in order to optimize the energy consumed by your applications over their whole life.
Commitment to ultralow power
Lower power consumption is increasingly required in all types of market applications. Several parameters are driving this demand: new national and international norms to reduce power consumption, the increasing number of batterypowered applications, development of new green technologies, or simply the need to be environmentally friendly. To better serve this market, STMicroelectronics is developing a platform of ultralowpower MCUs as a natural extension to the existing successful STM8S and STM32F families. This platform for the 8bit STM8L and 32bit STM32L MCUs is based on a proprietary 130 nm ultralowleakage process technology. The STM8L and STM32L offer specific features for ultralowpower applications, such as advanced ultralowpower modes, optimized dynamic run consumption and specific safety features. The balance between high performance and ultralow power using different modes ensures optimal energy consumption, whatever your application, and this throughout its life. ST's commitment to ultralow power is total, with ongoing development of future technologies and devices that will complement the existing portfolio of ultralowpower MCUs to give our customers access to a new level of power saving.
8/32bit ultralowpower range
STMicroelectronics' ultralowpower portfolio includes the full range of 8bit to 32bit MCUs, and so addresses most applications requiring reduced current consumption, from ultrasimple, costoptimized feature needs to complex, highperformance requirements.

STM8L ultralowpower MCU family
STMicroelectronics proposes an ultralowpower family of MCUs based on the 8bit and 32bit cores. The STM8L MCU family, based on the STM8 proprietary core, is the entry point of the platform. The STM8L family combines high performance and ultralow power consumption using a new proprietary ultralow leakage process and optimized architecture. This family is available in four different lines, making the STM8L an optimal family to support many applications with special care on power savings. The STM8L101 is the entry point for the ultralowpower 8bit portfolio. It is cost optimized and offers a high level of integration in an ultrasmall footprint. The STM8L151 is the featurerich 8bit solution. The STM8L152 has an additional LCDsegment driver compared to the STM8L151. The STM8L162 has an additional 128bit encryption (AES) feature compare to STM8L152.

STMTouch open library
STMicroelectronics' touchsensing software library is a complete, freeofcharge sourcecode solution to transform any 8bit STM8L microcontroller into a capacitive touchkey controller. Designers can combine the touchsensing function with multiple configurations (touch keys, wheels, sliders) and the traditional MCU features (communication, LED control, beeper, LCD control). The touchsensing software library is part of the application firmware.
Notes: - POR/PDR on - RAM content preserved - BOR option at 2.4 A - Startup time from active Halt 5 s - Run and Wait consumption values are independent of VDD - Active Halt and Halt values measured at VDD = 1.8 V

Evaluation boards
STM8L101 LCD board: STEVALIAS003V1 STM8L101 lowpower demonstrator with software driven LCD. Featuring 1.25 A consumption at 36 MHz refresh rate with a 3digit LCD glass driven by software, this tool highlights the optimized power consumption with the STM8L101. It is also provided at a very low cost.
STM8L15x lowpower board: STM8L15LPBOARD Ultralowpower and lowcost board for STM8L15x to demonstrate the different lowpower modes and functionalities and provide a means to measure current sourced by the battery while paused in each of the modes.
STM8L101EVAL, STM8L1526EVAL and STM8L1528 EVAL Complete hardware emulation platforms with respectively the STM8L101, the STM8L152 or STM8L16x, implementing the full range of device peripherals and features.
STMT/8LEV1 The board manages 10 keys, 1 wheel and 1 slider. The user can easily evaluate the touchsensing software features and performances, and display or change parameters through an LCD display interface.
Starter kits
STM8LDISCOVERY The STM8LDiscovery kit is the cheapest and quickest way to discover the STM8L and its lowpower capabilities. It includes a 6digit LCD display, 2 LEDs, 1 user button, current measurement and the embedded debugger STLINK.
STM8L1526PRIMER Play, explore and develop applications on the EvoPrimer STM8L with Raisonance toolset, free demos and an online community at www.stm8circle.com to stimulate creative designs.
