STM32W108CB, STM32W108HB
Description
Doc ID 16252 Rev 3
GPIO pins will wake up the chip. The STM32W108 has a fast startup time (typically 100 s)
from deep sleep to the execution of the first ARM Cortex-M3 instruction.
The STM32W108 contains three power domains. The always-on high voltage supply powers
the GPIO pads and critical chip functions. Regulated low voltage supplies power the rest of
the chip. The low voltage supplies are be disabled during deep sleep to reduce power
consumption. Integrated voltage regulators generate regulated 1.25 V and 1.8 V voltages
from an unregulated supply voltage. The 1.8 V regulator output is decoupled and routed
externally to supply analog blocks, RAM, and Flash memories. The 1.25 V regulator output
is decoupled externally and supplies the core logic.
The digital section of the receiver uses a coherent demodulator to generate symbols for the
hardware-based MAC. The digital receiver also contains the analog radio calibration
routines and controls the gain within the receiver path.
In addition to 2 general-purpose timers, the STM32W108 also contains a watchdog timer to
ensure protection against software crashes and CPU lockup, a 32-bit sleep timer dedicated
to system timing and waking from sleep at specific times and an ARM standard system
event timer in the NVIC.
The STM32W108 integrates hardware support for a Packet Trace module, which allows
robust packet-based debug. This element is a critical component of InSight Desktop, the
Ember software IDE, and provides advanced network debug capability when used with
Ember's InSight Adapter.
Note:
The STM32W108 is not pin-compatible with the previous generation chip, the SN250,
except for the RF section of the chip. Pins 1-11 and 45-48 are compatible, to ease migration
to the STM32W108.
1.2.2
ARM Cortex-M3 core
The STM32W108 integrates the ARM Cortex-M3 microprocessor, revision r1p1,
developed by ARM Ltd, making the STM32W108 a true system-on-a-chip solution. The
ARM Cortex-M3 is an advanced 32-bit modified Harvard architecture processor that has
separate internal program and data buses, but presents a unified program and data address
space to software. The word width is 32 bits for both the program and data sides. The
ARM Cortex-M3 allows unaligned word and half-word data accesses to support efficiently-
packed data structures.
The ARM Cortex-M3 clock speed is configurable to 6 MHz, 12 MHz, or 24 MHz. For
normal operation 12 MHz is preferred over 24 MHz due to its lower power consumption. The
6 MHz operation can only be used when radio operations are not required since the radio
requires an accurate 12 MHz clock.
The ARM Cortex-M3 in the STM32W108 has also been enhanced to support two separate
memory protection levels. Basic protection is available without using the MPU, but the usual
operation uses the MPU. The networking stack software runs in Privileged mode, which
allows full, unrestricted access to all areas of the chip, while application code runs in User
mode. In User mode, reading or writing to certain areas of memory and registers is
restricted to prevent common software bugs from interfering with network software
operation. Errant writes are captured and details are reported to the developer to assist in
tracking down and fixing issues.
