Notes:
1.EXT_SEL
：
VDD +1.2 V Select. Select external +1.2 V supply. Tie to DVDD33 if
the +1.2 V supply is to be provided externally. Tie to VSS (0 V) if the +1.2
supply is to be generated internally.
2.VDD12_CTRL
：
VDD +1.2 V Control. Analog control line for the voltage regulator
external FET when EXT_SEL is tied to VSS. When EXT_SEL is tied to DVDD33, the
VDD12_CTRL pin becomes a CMOS output which can drive the shutdown input of an
external LDO.
3.Please place one 0.1uF/10V(20%) CAP close to each of the Power Pins.
Maximum frequency of master SPI clk = 8 MHz.
NC.Test Points Reserved.
Notes:
1.HCLK:This input should be tied to VSS in I2C mode;
2.HCS:HBI I2C Serial Clock Input. This pin functions as the I2C_SCLK
input in I2C mode.
3.HDIN:This input selects the slave address in I2C mode,to VSS,I2C slave
address:0'b 100 0101=0x45H(7-bit).
4.HDOUT:HBI I2C Serial Data (Input/Output). This pin functions as the
I2C_SDA I/O in I2C mode.
5.Apply a 3.3 K? resistor from GPIO_2 to DVDD33,can set auto-boot from
external flash;if GPIO_2=0,Host boot(default).
TDMB not in use:
connect to GND
Power Supply for DSP:
Notes:
1.Vout=1.204*(1+R1/R2)=3.296V;
R1=52.3K,R2=30.1K are recommended for better performance.
2.RT9043GB from RichTek for second source.
Notes:
1.Vout=1.204*(1+R1/R2)=1.204V;
R1=short,R2=open are recommended for better performance.
