COMPONENTS DESCRIPTION
When the base of Q5 goes Hi, PAN5V is supplied for IC2.
When the base goes Hi, GRID1 is ON.
When the base goes Hi, GRID2 is ON.
When the base goes Hi, GRID3 is ON.
When the base goes Hi, left sub-illumination is ON.
When the base goes Hi, center 3-key illuminations are ON.
When the base goes Hi, right sub-illuminations are ON.
Controls DSP and peripheral circuit.
USB host controller. (Compliant with Universal Serial Bus Specifi cation Rev2.0)
Built-in MP3·WMA·AAC decoder.
Built-in 1M-bit-SRAM.
Driver for focusing & tracking coil, driver for sled & spindle motor, and operation
for disc loading & ejection.
Connection authentication for iPod.
MFI341S2162: iPhone-compliant.
Converts communication signal from 3.3V to 5.0V.
Converts communication signal from 5.0V to 3.3V.
Power supply for digital back-up.
Power supply for mechanism μ-COM.
Memory for ROM correction.
Countermeasure for software malfunction.
Power supply for digital, analog and audio line.
The output voltage in which the power supply that diverges from the BU1.5V line
is turned on and off is used as D1.5V.
The output voltage in which the power supply that diverges from the BU3.3V line
is turned on and off is used as D3.3V.
Controls Q5.
Laser diode driver.
Because the detection logic of LOE/LIM_SW is different in the mechanism
μ-COM and the system μ-COM, the logic to the mechanism μ-COM side is
reversed.
Prevents reverse bias which is applied to laser.
Laser destruction prevention.
The potential difference between DGND and AGND is absorbed, and the
malfunction by static electricity is prevented.
