TC9446F  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC9446F  
Audio Digital Processor for Decode of Dolby Digital (AC-3), MPEG2 Audio  
TC9446F is the various digital signal processor for decoding. It  
contains the decode processing program which embraced  
encoding signals, such as Dolby Digital (AC-3)/Pro Logic (Note 1),  
MPEG2 audio and DTS (Note 2).  
Decoding of Dolby Digital or MPEG2 audio is made with a  
single chip. Moreover, an external memory can be connected to  
the TC9446F to decode DTS.  
Features  
Dolby digital (AC-3) or MPEG2 audio decode  
Acceptable bit rate upto 640 kbps  
Audio interface  
Weight: 1.57 g (typ.)  
4 output port, 2 input port (2 port of LRCK and BCK)  
DIR (digital audio interface receiver) built-in  
DIT (digital audio interface transmitter) built-in  
DIR and DIT are available upto 96 kHz sampling of 2 channel  
Operating clock: DLL oscillator upto 6th times for DSP clock  
Instruction cycle: 20 ns/1 instruction at 50 MIPS operation  
DSP  
Processor: 24 bit × 24 bit + 51 bit multiplier and adder, 51 bit ALU  
Data bus: 24 bit × 3  
Data RAM: 12 k word  
Coeficient ROM: 4 k word  
Program ROM: 12 k word  
Program RAM: 128 word  
MCU interface: Serial interface or I2C bus interface  
Others  
It is possible to connect external RAM, 256 k or 1 M SRAM  
External interruption input terminal  
Flag input terminal: 4 inputs  
General-purpose output port: 8 outputs (The ports can be used as interrupt outputs to MCU and logic control  
outputs.)  
incorrect operation detect  
Operating Voltage: 3.0 ± 0.3 V  
In CMOS structure and high-speed processing  
100 pin flat package design  
Note 1: “Dolby”, “Pro Logic”, and the double-D symbol are trademarks of Dolby Laboratories.  
Note 2: “DTS” and “DTS Digital Surround” are registered trademarks of Digital Theater Systems, Inc.  
Note 3: Since this product has a weak terminal in serge voltage, please advise handling it enough.
