TC9496AF
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC9496AF
1 Chip Audio Digital Signal Processor
TC9496AF 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,
dynamic range control, KARAOKE and something.
Features
· Incorporates 3 ch AD converter, 2 ch is 1 bit Σ-∆ type AD
converter for HiFi-Audio and 1 ch is 16 bit Multi-bit type AD
converter for Microphone.
Weight: 1.57 g (typ.)
2 ch HiFi-ADC (1 bitΣ-∆ type) S/N: 96dB (typ.)
1 ch Mic. ADC (16 bit Multi-bit type) S/N: 80dB (typ.)
· Incorporates 1 bitΣ-∆ 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 (1 bitΣ-∆ type) S/N: 96dB (typ.)
Attenuator for trim 0dB to −24dB (1dB step)
· Each port has a digital input/output.
· A built-in self-boot function automatically sets the coefficients and register values at initialization.
Moreover, four kinds of boot data can be chosen by pin setup.
Boot ROM: 1024 word × 18 bit
· The DSP block specification are as follows:
Data bus: 24 bit
Multiplier/adder: 24 bit × 16 bit + 43 bit → 43 bit
Accumulator: 43 bit (sign extension: 4 bit)
Program ROM: 2048 word × 32 bit
Coefficient RAM: 448 word × 16 bit
Coefficient ROM: 256 word × 16 bit
Offset RAM: 64 word × 16 bit
Data RAM: 256 word × 24 bit
Operation speed: 44 ns (510-step (approx.) operation per cycle at fs = 44.1 kHz)
Interface buffer RAM: 32 word × 16 bit
· Incorporates data delay RAM of 64 kbit.
Delay RAM: 4096 word × 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.
