Functional overview
STM32L151xx, STM32L152xx
Doc ID 17659 Rev 1
PLL, MSI RC, HSI RC and HSE crystal oscillators are also switched off. After entering
Standby mode, the RAM and register contents are lost except for registers in the
Standby circuitry (wakeup logic, IWDG, RTC, LSI, LSE Crystal 32K osc, RCC CSR).
The device exits the Standby mode in 60 s when an external reset (NRST pin), an
IWDG reset, a rising edge on one of the three WKUP pins, RTC alarm (Alarm A or
Alarm B), RTC tamper event, RTC timestamp event or RTC Wakeup event. The
Standby mode consumption is of 1A (at 1.8 V) and 1.3 A (at 3.0 V) with the RTC on,
and of 270 nA with the RTC off.
Note:
The RTC, the IWDG, and the corresponding clock sources are not stopped by entering the
Stop or Standby mode.

ARM Cortex-M3 core with MPU
The ARM Cortex-M3 processor is the latest generation of ARM processors for embedded
systems. It has been developed to provide a low-cost platform that meets the needs of MCU
implementation, with a reduced pin count and low-power consumption, while delivering
outstanding computational performance and an advanced system response to interrupts.
The ARM Cortex-M3 32-bit RISC processor features exceptional code-efficiency,
delivering the high-performance expected from an ARM core in the memory size usually
associated with 8- and 16-bit devices.
The memory protection unit (MPU) improves system reliability by defining the memory
attributes (such as read/write access permissions) for different memory regions. It provides
up to eight different regions and an optional predefined background region.
Owing to its embedded ARM core, the STM32L15xxx is compatible with all ARM tools and
software.
Nested vectored interrupt controller (NVIC)
The ultralow power STM32L15xxx embeds a nested vectored interrupt controller able to
handle up to 45 maskable interrupt channels (not including the 16 interrupt lines of
Cortex-M3) and 16 priority levels.
●
Closely coupled NVIC gives low-latency interrupt processing
●
Interrupt entry vector table address passed directly to the core
●
Closely coupled NVIC core interface
●
Allows early processing of interrupts
●
Processing of late arriving, higher-priority interrupts
●
Support for tail-chaining
●
Processor state automatically saved
●
Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimal interrupt
latency.
