STMicroelectronics STM8L Microcontroller

The STMicroelectronics STM8L microcontroller (MCU) uses a new proprietary ultra-low leakage process and optimized architecture to provide high performance and ultra-low power consumption. The STMicroelectronics STM8L MCU, which includes the STM8L101xx and STM8L15xx, is based on the 8-bit STM8 core and is ideal for many applications with special care on power savings. The STM8L embeds up to 4 different ultra low-power modes to offer users a high level of flexibility. This STMicroelectronics 8-bit MCU offers a high level of integration and a compact footprint. The STM8L-DISCOVERY Board is ideal for evaluating these high performance MCUs.

STMicroelectronics STM8L Benefits
STMicroelectronics STM8L Features
  • Speed and power consumption independent of MCU power supply, Ultra-low leakage
  • Reduced overall run and wait mode current consumption by turning off clocks of unused peripherals or Flash
  • Ultra-low-power modes for applications requesting regular wake up
  • Suitable for many applications from complete switch off to continuous monitoring at ultra low frequency
  • Switch and adjust frequency and clock sources on the fly depending on application needs
  • Autonomy for peripherals, independent from core; can switch off Flash memory and CPU (large current consumption contributors) while keeping peripherals active
  • Integrated safety and security for application
  • Fast switching from static and dynamic power modes
  • Full functionality over the complete Vdd range
  • Ultra-low-power proprietary 130 nm technology
  • Ultra-low-power design (clock gating, low-power Flash with power-off capability)
  • Sub 1 μA hardware RTC and AWU system unit
  • Range of low-power modes (up to 4)
  • Advanced and flexible clock system (multiple internal and external clock sources)
  • Direct memory access on board (4-channel DMA)
  • Ultra-low-power and ultra-safe reset system POR/PDR; additional optional activation BOR
  • Ultra-fast wake up from lowest low-power mode (4 μs)
  • Analog functional down to 1.8 V, programming down to 1.65 V
