The HDa12 Baseband architecture is similar to DCT3 phones. All the ASICs are in the uBGA package. COBBA GJP, which has a serial interface to the MAD, is used. EEPROM is software emulated in the Flash-memory.

The HDa12 phone supports'ELVI' (DCT3) and 'Jeanette' (DCT4) chargers, both 2-wire and 3-wire, but when using 3-wire chargers, then the 3rd. wire (charger control input) is connected to Ground by the phone.
