NOTES:
1. For unused pins :
♦The unused input pins must be connected to the GND (0 V) level if there is no individual note in the above table.
♦The unused output pins must be left open (No connection) if there is no individual note in the above table.
♦The unused input/output pins must follow the below conditions if there is no individual note in the above table:
Input setting
Leave open with internal pull−down resistor ON.
With using internal pull−down resistor OFF, connect to GND (0 V) or connect to power pins for I/O.
However, use of individual pull−up or pull−down resistor is recommended as fail−safe.
Output setting
Leave them open.
2. For power supply pins:
♦Same voltage level must be supplied to DVDD, AVDD1, AVDD2, XVDD and VVDD2 power supply pins.
(Refer to “Allowable operating ranges”)
3. For “Reset” condition:
♦This IC is not reset only by making the RESB pin “Low”.
Refer to “Power on and Reset control” for detail of “Reset” condition.
4. For “Analog Source” unused pins (15 pin to 22 pin) :
♦The “Analog Source” unused pins (15 pin to 22 pin) must be connected to the GND (0V) level through the input coupling capacitor or
be left open (No connection).

Power−ON/Reset Control
•Notes on Power−On
1. Regarding Reset Pin
To stabilize the operation condition of the internal FlashROM, RESB pin must need to be “L”.
If RESB pin is “H” at the Power−On, operation condition of the Flash memory becomes unstable and the operation of
this LSI becomes unstable. In this case, Reset by RESET pin control does not return to the normal state, RESB pin
must be “L” at the Power−On
2. Regarding Volume Out
Volume output becomes unknown state when Power−On, external circuit must care by muting/etc. from external
circuit

Reset period (at Power−On) tRESW1 20 ms
Reset period (When normal operation) (Note 5) tRESW2 1 ms
5. Reset period at normal operation is the period that clock is stablely oscillating.
Need to care about clock stable time when making clock OFF by commands.
−Regarding RESB pin control and internal Flash memory
As stated above, reset of the operation state of the flash memory in this LSI cannot be controlled by only RESB pin, and
needs Power−On−Reset. Therefore, when flash memory goes to runaway state during the power is on, Power−On−Reset
must be done. In this case, users must power off the LSI and execute the Power−On−Reset.
On the other hand, reset control by RESB pin is effective to the circuit other than the flash memory. By making RESB pin
to “L” for the time period stated above with the stable clock, the circuit except flash memory is initialized. Also, by this
operation, flash memory becomes stand−by state and states of the memory cells are kept

Microcontroller Interface
Reception/Transmission from the host microcontroller is done by the SPI synchronous SIO communication.
The format of the data transmission is as below
−Code of M5 to M0 at the ModeCode transmission must be followed by the specification of the internal software inside
this LSI.
When data input in M5 to M0 and value in the internal register matches, SIFDO becomes “L” (Ack) and communication
will be enabled. If no match, SIFDO becomes “H” (Nack) and communication will not be enabled.
−Judgement whether command transmission or reception will be done by the 7th bit data of the ModeCode transmission.
“L” means command transmission and “H” means data reception
−Need to care the communication timing specification because the specification differs by operational mode (normal /
low speed) of the internal microcontroller

Stream Data Input/Output Function
There are 2 ways to input/output the stream data.
1. 4−wire method
Stream Input :During STREQO = “H” output, input STLRCKI/STBCKI/STDATI.
In the case of 4−wire method, STLRCKI/STBCKI/STDATI (input state) are normal audio
inputs/outputs. As same as the format, 4 byte (32 bit) data transmission/reception is done in one
period of STLRCKI (input state).
2. 3−wire method
Stream Input : Input STBCKI/STDATI while STREQO = “H” output.
Stream Output : Output STBCKO/STDATO while STREQI = “H” input.
In the case of 3−wire method, depending on the state of STREQO, only inputs the bit clock and data, or depending on
the state of STREQI, only outputs the bit clock and data, and data communication unit becomes 2 byte (16 bit). Also
in the 3−wire method of the stream output, it is possible that users just input the clock (STBCKI) and it will output
the data only.

NOTE: When each pin is set as stream input simultaneously, they will be processed as below priority;
(1) GP30 to 33, (2) GP40 to 43, (3) GP50 to 53
For example, if set all pins to stream input mode, stream data will be processed on only data in GP30 to 33. Data
in GP40 to 43, GP 50 to 53 will not be processed in the LSI.

<Additional Information>
Clock input mode supports 2 types and data output timing changes as below accordingly;
1. Starting from STBCKI = “L”
STDATO will be output synchronizing with the rising edge of STBCKI.
2. Starting from STBCKI = “H”.
STDATO will be output synchronizing with the falling edge of SBCKI.
Using each mode of (1) or (2) does not change the output characteristics.

<Notes>
♦Because the characteristics of oscillator could be changed according to the circuit board, ask evaluation with the
individual original circuit board to the oscillator maker.
♦The precision of oscillator used in XIN/ XOUT should meet the USB standard.
♦If oscillation clock is disturbed by noise or by the other factors, it may lead to operation failure. Hence, make sure to
connect resistor and capacitor for oscillation circuit as close as XIN/ XOUT and the wire should be as short as
possible. Also needs to select parts with caution so as to obtain stable external constant value within the guaranteed
operating temperature range because the variation of external constant due to temperature change could affect the
oscillation precision

•About PLL
LC786820E includes PLL1 and PLL2.
PLL1 is for generating system clock and PLL2 is for generating Audio clock.
•External filter constant for PLL2

Rp1 = 3.3 kW / Cp1 = 3300 pF / Cp2 = 220 pF
<Notes>
♦This PLL filter circuit of resistor (Rp1) and capacitance (Cp1, Cp2), are for audio generation/system clock
generation connected to AFILT. If oscillation clock is disturbed by noise or by the other factors, it may lead to
operation failure. Hence, make sure to connect resistor and capacitor that constitute filter circuit as close as AFILT
and the wire should be as short as possible. Also if filter constant changes due to temperature change, oscillation of
PLL may become unstable and the following problem may occur:
