LC786960E
CMOS LSI
Compact Disc Player IC
http://onsemi.com
Overview
The LC786960E integrates ARM7TDMI-S™, CD servo control, CD signal processing, compressed audio decode
processing, audio signal processing, USB host processing, SD memory card host processing and a flash memory to
store the program for ARM7TDMI-S™ and various data in a package. Furthermore, various kinds of interface
functions such as SIO, UART etc. reduce the external main controller’s processing load and make high performance
and much functional CD player system, using with less components.

RF signal processing for CD-DA/R/RW, servo control, and EFM signal processing
MP3*, WMA*, AAC* decoder processing
Sampling rate convertor, High frequency compensation filter and other various audio signal processing
USB host function (Full speed as 12Mbps), SD memory card host function
ARM7TDMI-S™ as internal CPU core, flash memory for program and various data storage
Operating voltage: 3.3V typical
Operating temperature: -40C to +85C
Packages: QIP100E (14 20)

<Note>
(1) For unused pins:
The unused input pins must be connected to the GND (0V) 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 be connected to the GND (0V) or power supply pin for I/O block with internal
pull down resistor OFF or be left open with internal pull down resistor ON when input pin mode or must be left
open (No connection) when output pin mode if there is no individual note in the above table.
When you connect an I/O pin which is an input pin without internal pull-down resistor at reset mode to the GND
or power supply level, we recommend you to use pull-down resistor or pull-up resistor individually as fail-safe.
(2) For power supply pins:
Same voltage level must be supplied to DVDD, AVDD, XVDD1, XVDD2, VVDD1, VVDD2, VVDD3, UVDD
and LRVDD power supply pins.
(Refer to“Allowable operating ranges”.)
(3) For “Reset” condition:
This LSI is not reset only by making the RESB pin “Low”.
Refer to “Power on and Reset control” for detail of “Reset” condition.

Power on and Reset control
Attention when power on
The RESB pin must be set to “Low” level to initialize the operating state of internal flash memory.
If the power is on during the RESB pin is “High” level, this LSI may operate incorrectly because the internal flash
memory is not initialized. In this case, this LSI is not initialized even if a low level supplied to RESB pin.
Therefore, the RESB pin must be set to “Low” level when power is first supplied.
You may input the voltage of 3.6V or less to each input pin when the power supply is off. However, it is necessary
to supply a regulated voltage to the power supply pin beforehand when more than 3.6V voltage is input to the 5V
tolerant input pins.

When the X16 clock has been stopped by the command etc. , the specification of tRESW2 could be larger than the
value shown above, because it takes time that the X16 oscillator becomes stable.

Host interface
The data transmission between this LSI and Host controller is performed with SPI type synchronous SIO protocol.
The transmission procedure is as follows.
Refer to the internal software specification of this LSI about M5 to M0 code in Mode code transmission.
When the input data of M5 to M0 coincide to the data in the internal register, the SIFDO pin becomes to “Low”
level (Ack) then the transmission is enabled.
When not coincide, the SIFDO pin keeps “High” level (Nack) then the transmission is not enabled.
The seventh data in Mode code transmission shows whether the following procedure is the Command transmission
or the Data reception. When the seventh data is “Low”, the following procedure is Command transmission. When
the seventh data is “High”, the following procedure is Data reception.
Attention because the specifications of transmission timings are different depending on the internal CPU’s operating
speed modes (Low speed or Normal speed). Refer to the table in next page.
