TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
T C 9 4 7 2 F
1 chip AUDIO DIGITAL SIGNAL PROCESSOR
TC9472F is the 1 chip audio DSP which built in 24-bits, a 22.5 MIPS
DSP core, 3 ch AD converter, 5 ch DA converter, and electronic
volume for trims, and corresponds to a Multi-speaker system.
It is possible to realize many application, such as sound field control
- hall simulation,for example - , digital filter for equalizers, dyanmic
range control, KARAOKE and something.
FEATURES
Incorporates 3 ch AD converter, 2 ch is 1bit
Σ - type AD converter for
HiFi - Audio and 1 ch is 16 bit Multi-bit type AD converter for Microphone.
2 ch HiFi-ADC (1bit
Σ - type)
S / N : 98 dB (typ.)
1 ch Mic. ADC (16 bit Multi - bit type)
S / N : 80 dB (typ.)
Incorporates 1bit
Σ - type DA converter, and the attenuator for trims
is built in each DAC output. In case of the use which does not use a trim,
It is possible to output the analog signal of DAC directly.
5 ch DAC (1bit
Σ - type)
S / N : 100 dB (typ.)
A built-in self-boot function automatically sets the coefficients and register values at initialization.
Boot ROM
: 1024 word x 18 bit
The DSP block specification are as follows :
Data bus
: 24 bit
Multiplier / adder
: 24 bit x 16 bit + 43 bit => 43 bit
Accumulator
: 43 bit (sign extension : 4 bit)
Program ROM
: 2048 word x 32 bit
Coefficient RAM
: 448 word x 16 bit
Coefficient ROM
: 256 word x 16 bit
Offset RAM
: 64 word x 16 bit
Data RAM
: 256 word x 24 bit
Operation speed
: 44 ns (510-step (approx.) operation per cycle at fs = 44.1 kHz)
Interface buffer RAM : 32 word x 16 bit
Incorporates data delay RAM of 64 kbit.
Delay RAM
: 4096 word x 16 bit (64 kbit)
The microcontroller interface can be selected between TOSHIBA original 3 line type and I2C bus format.
CMOS silicon structure supports high speed.
The package is a 100-pin flat package.
