FUNCTIONAL DESCRIPTION
INTRODUCTION
FUNCTIONAL DESCRIPTION
INTRODUCTION
The 34827 is used to identify what is attached to the Mini
or Micro-USB connector, configure the signal paths between
the phone baseband and the 5-pin connector accordingly,
and then inform the baseband of the attachment. It also
detects the detachment of accessory and then informs the
baseband.
To identify what is plugged into the Mini or Micro-USB
connector, the 34827 supports various detection
mechanisms, including ID detection and VBUS detection.
The detection flow is initiated either by the change of VBUS
pin voltage or by the change of ID pin voltage. A high
resistance. Each level of resistance can be assigned to an
accessory or a button in a cord remote controller. Some non-
supported accessories, such as video cable, Phone-Powered
Devices, USB OTG devices and so on, can also be identified.
For 34827, the mapping relationship between the ADC
values and the types of accessories is fixed and the detailed
The detachment of accessory is also monitored by both of
the ID detector and the VBUS detector.
The host IC can control the 34827 via an I 2 C serial bus.
accurate 5-bit ADC is offered to distinguish the 32 levels of ID
FUNCTIONAL PIN DESCRIPTION
SPEAKER RIGHT CHANNEL (SPK_R)
Right channel of the baseband speaker output.
SPEAKER LEFT CHANNEL (SPK_L)
Left channel of the baseband speaker output.
MICROPHONE OUTPUT (MIC)
Microphone output to the baseband.
D+ OF THE USB TRANSCEIVER (D+)
D+ line of the USB transceiver.
D- OF THE USB TRANSCEIVER (D-)
D- line of the USB transceiver.
UART RECEIVER (RXD)
Receiver line of the UART.
UART TRANSMITTER (TXD)
Transmitter line of the UART.
BOOT INDICATOR (BOOT)
VDDIO referenced push-pull output to indicate the boot
switch setting of jig cables.
IO POWER SUPPLY (VDDIO)
Power supply input for the logic IO interface. Generally the
IO power supply voltage should be the same as the IO
voltage used in the cell phone system. VDDIO is also one of
hardware reset input sources. A falling edge at this pin will
reset the 34827.
JIG INDICATOR (JIG)
Open-drain output to indicate the insertion of a jig cable.
POWER SUPPLY (VDD)
Power supply input. Bypass to ground with a 1.0 μ F
capacitor.
INTERRUPT OUTPUT (INTB)
Active low and VDDIO referenced push-pull output. When
the 34827 detects a change of external cable status, this pin
outputs low voltage to interrupt the baseband. INTB returns
to high voltage once all the interrupt bits are read.
DATA LINE OF THE I 2 C INTERFACE (I2C_SDA)
Data line of the I 2 C interface. I2C_SDA together with
I2C_SCL is one of hardware reset input sources.
CLOCK LINE OF THE I 2 C INTERFACE(I2C_SCL)
Clock line of the I 2 C interface. I2C_SCL together with
I2C_SDA is one of hardware reset input sources.
POWER OUTPUT (OUT)
Output of the power MOSFET in the 34827. This pin is
connected to a charger. Bypass to ground with a 1.0 μ F
capacitor.
CHARGE CURRENT SETTING (ISET)
Open-drain output to set the charge current for a charger
according to the VBUS power supply type.
VBUS POWER SUPPLY (VBUS)
Mini-USB VBUS input. Bypass this pin to ground with a
less than 10nF capacitor. When the attached accessory is an
audio kit, this pin is the microphone input to the 34827.
D- OF THE USB CONNECTOR (DM)
D- line of the mini-USB connector.
