Functional description
The heart of the BB is UPP_WD2, which includes the MCU, DSP and Digital Control Logic.
Power is supplied by the UEMK ASIC and a number of discrete regulators. Memory comprises
of 4 x 64Mbit Flash Memory Devices and 128 Mbit (16 Mbytes) SDRAM.
There are two audio transducers (Earpiece 8 mm and IHF Speaker 16 mm) and an External
Galvanic Headset (DCT4) interface. The IHF Speaker is also used to handle the ring tone. The
IHF Speaker is driven by a discrete audio amplifier. In NHL-10 there is only one microphone
for both HS and IHF modes.
For Data connectivity there is a 115.2kbit IR Module (IrDA compatible), Bluetooth and MMC
card.
The Display is an TFT type Colour Display with 65536 Colours and 176x208 pixels with back-
lighting. The UI module features a keymat and a navigation key.
For imaging purposes, the BB supports a VGA camera via the CCP interface, which is inte-
grated into UPP_WD2.
