TC9496AF

`Incorporates 3 ch AD converter, 2 ch is 1 bit - type AD converter for HiFi-Audio and 1 ch is 16 bit Multi-bit type AD converter for Microphone. 2 ch HiFi-ADC (1 bit- type) S/N: 96dB (typ.) 1 ch Mic. ADC (16 bit Multi-bit type) S/N: 80dB (typ.)
`Incorporates 1 bit- 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 bit- 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 I<sup>2</sup>C bus format.
`CMOS silicon structure supports high speed.
`The package is a 100-pin flat package.

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.

TC9496AF 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.
