Packet trace interface (PTI)
The STM32W108 integrates a true PHY-level PTI for effective network-level debugging. It
monitors all the PHY Tx and Rx packets between the MAC and baseband modules without
affecting their normal operation. It cannot be used to inject packets into the PHY/MAC
interface. This 500 kbps asynchronous interface comprises the frame signal (PTI_EN, PA4)
and the data signal (PTI_DATA, PA5).
Random number generator
Thermal noise in the analog circuitry is digitized to provide entropy for a true random
number generator (TRNG). The TRNG produces 16-bit uniformly distributed numbers. The
Software can use the TRNG to seed a pseudo random number generator (PNRG). The
TRNG is also used directly for cryptographic key generation.
CRC generation, appending, and checking
Hardware timers and interrupts to achieve the MAC symbol timing
Automatic preamble and SFD pre-pending on Tx packets
Address recognition and packet filtering on Rx packets
Automatic acknowledgement transmission
Automatic transmission of packets from memory
Automatic transmission after backoff time if channel is clear (CCA)
Automatic acknowledgement checking
Time stamping received and transmitted messages
Attaching packet information to received packets (LQI, RSSI, gain, time stamp, and
packet status)
