STM32WB Wireless System-on-Chip
The Sharky modules are based on STMicroelectronics STM32WB55CE, a dual-core MCUs
with wireless support are based on an Arm® Cortex®
-
M4 core running at 64 MHz
(application processor) plus an Arm® Cortex®
-
M0+ core at 32 MHz (network processor).
The STM32WB platform is an evolution of the well

power series of MCUs. It provides the same digital and analog peripherals suitable
for applications requiring extended battery life and complex functionalities.
STM32WB proposes a variety of communication assets, a practical crystal-less USB2.0 FS
interface, audio support, an LCD driver, up to 72 GPIOs, an integrated SMPS for power
consumption optimization, and multiple low-power modes to maximize battery life.
On top of wireless and ultra

power aspects, a particular focus was placed on embedding
security hardware functions such as a 256

bit AES, PCROP, JTAG Fuse, PKA (elliptic curve
encryption engine), and Root Secure Services (RSS). The RSS allows authenticating OTA
communications, regardless of the radio stack or application.
