Figure 5. STM32L152RCT6 package
The STM32L152RCT6 provides the following benefits:
•
Ultra low power proprietary 130 nm technology: speed and power consumption
independent of MCU power supply, and ultra low leakage
•
Ultra Low power design (clock gating, low-power Flash with power-off capability):
reduced overall Run and Wait mode current consumption by turning off clocks of
unused peripherals or Flash
•
Sub 1 µA hardware RTC and AWU system unit:
Ultra-low-power modes for applications requesting regular wake up
•
Up to 6 Low-power modes: suitable for many applications from complete switch off to
continuous monitoring at ultra low frequency
•
Advanced and flexible clock system (multiple internal and external clock sources):
switch and adjust frequency and clock sources on the fly depending on application
needs
•
Direct memory access on board (up to 12 DMA channels): autonomy for peripherals,
independent from the core; can switch off Flash memory and CPU (large current
consumption contributors) while keeping peripherals active
•
Ultra Low power and ultrasafe features (POR, PDR, BOR, PVD) allowing integrated
application safety and security
•
Unique identifier to enhance user data confidentiality/reliability
•
Ultrafast wakeup from lowest consumption low-power mode allowing fast switching
from static and dynamic power modes
•
Analog functional down to 1.8 V, and programming down to 1.65 V
•
Full functionality over the complete V
DD
range
