Description
received packets. A packet trace interface is also integrated with the MAC, allowing
complete, non-intrusive capture of all packets to and from the STM32W108.
The STM32W108 offers a number of advanced power management features that enable
long battery life. A high-frequency internal RC oscillator allows the processor core to begin
code execution quickly upon waking. Various deep sleep modes are available with less than
1 µA power consumption while retaining RAM contents. To support user-defined
applications, on-chip peripherals include UART, SPI, I2C, ADC and general-purpose timers,
as well as up to 24 GPIOs. Additionally, an integrated voltage regulator, power-on-reset
circuit, and sleep timer are available.
1.1 Development tools
The STM32W108 implements both the ARM Serial Wire and JTAG debug interfaces. These
interfaces provide real time, non-intrusive programming and debugging capabilities. Serial
Wire and JTAG provide the same functionality, but are mutually exclusive. The Serial Wire
interface uses two pins; the JTAG interface uses five. Serial Wire is preferred, since it uses
fewer pins.
The STM32W108 also integrates the standard ARM system debug components: Flash
Patch and Breakpoint (FPB), Data Watchpoint and Trace (DWT), and Instrumentation Trace
Macrocell (DWT).
