TC94A04AF/AFD TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC94A04AF,TC94A04AFD 1 chip Audio Digital Processor TC94A04AF/AFD is a single-chip audio Digital Signal Processor, incorporating 4 way stereo analog switch, 2 ch AD converter, 4 ch DA converter, and electronic volume for trimming. It is possible to realize many applications, such as sound field control -hall simulation, for example-, digital filter for equalizers, surround, base boost and something. TC94A04AF Features • • • • • • Incorporates a 4 ch-stereo analog switch for AD converter input. Incorporates a 1 ch stereo line-out. Incorporates a 1 bit ∑ ∆-type AD converter (two channels). THD: −82dB (typ.) S/N: 95dB (typ.) Incorporates a 1 bit ∑ ∆-type DA converter (four channels). THD: −86dB (typ.) S/N: 98dB (typ.) Incorporates a trimming analog volume for each output of DA converter. 0dB to −24dB (1dB step) As digital input/output port, this has 3 input port (6 ch) and 1 output port (2 ch), enabling input/output of sampling of 96 kHz/24 bit. Incorporates a built-in digital de-emphasis filter. Incorporates a digital attenuator. Weight QFP60-P-1414-0.80D : 1.08 g (typ.) QFP80-P-1420-0.80B : 1.57 g (typ.) TC94A04AFD • • • Incorporates a boot ROM to set a coefficient automatically, which enables to transfer an initial data from built-in ROM/RAM to registers at the time of resetting Boot ROM: 512 words The DSP block specifications are as follows: Data bus: 24 bits Multiplier/adder: 24 bits × 16 bits + 43 bits → 43 bits Accumulator: 43 bits (sign extension: 4 bits) Program ROM: 1024 words × 32 bits Coefficient RAM: 384 words × 16 bits Coefficient ROM: 256 words × 16 bits Offset RAM: 16 words × 11 bits Data RAM: 256 words × 24 bits Interface buffer RAM: 32 words × 16 bits Operation speed: 22.5 MIPS (510 step/fs: master clock = 768 fs, fs = 44.1 kHz) • • • • • • Note 1: At the time of an analog input, approximately 170 steps (85 step/ch) in 510 step are used for the operation of the decimation filter for AD converters. Incorporates data delay RAM (32 kbits). Delay RAM: 2048 words × 16 bits (32 kbits) The microcontroller interface can be selected between Toshiba original 3 line mode and I2C mode. CMOS silicon structure supports high speed. Power supply is a single 5 V. The package are 60-pin and 80 pin flat package. 1 2001-11-15 TC94A04AF/AFD Block Diagram/Pin Connection TC94A04AF DOUT TST1 TST0 IFDO IFCK DIN0 DIN1 DIN2 32 31 GND I2CS ERR RST VDD 36 35 IFDI 45 44 43 42 41 40 39 38 CS 37 34 33 LIN4 46 LIN3 47 LIN2 48 LIN1 49 RIN4 50 RIN3 51 RIN2 52 RIN1 53 GNDAL 54 OUTL 55 VRAL 56 VDALR 57 VRAR 58 OUTR 59 GNDAR 60 19 kΩ 19 kΩ 19 kΩ 19 kΩ C1 C1 Lch input Mute SW MCU Interface Audio serial interface EBCI/O 30 ELRI/O 29 SYNC 28 C2 C2 C3 20 kΩ 500 Ω C3 C4 C4 GNDR 27 Delay RAM VDDR 26 GNDA4 25 AI4 24 AO4 23 AOT4 22 VDA34 21 Ch3 DAC circuit AOT3 20 AO3 19 AI3 18 20 kΩ 41.5 kΩ Same as Ch1 DAC circuit 8 kΩ GNDA3 17 VRO2 16 BP BP VRAL Rch input Same as Lch input circuit 500 Ω DSP (I/O Interface) Ch4 DAC circuit Same as Ch1 DAC circuit 27 kΩ Σ∆ ADC VRAL Lch circuit 41.5 kΩ 15 kΩ 15 kΩ 15 kΩ Σ∆ DAC 15 kΩ 15 kΩ 15 kΩ Ch1 DAC circuit Ch2 DAC Circuit Same as Ch1 DAC circuit 27 kΩ Same as Lch circuit Oscillator circuit 7.8 kΩ 6 7 8 XO GNDX AOT1 VDA12 VDX AOT2 AI1 AO1 AO2 AI2 GNDA1 GNDA2 VRO1 XI BP BP 2 VRI 1 2 3 4 5 4 kΩ 9 10 11 12 13 14 15 2001-11-15 TC94A04AF/AFD TC94A04AFD DOUT EBCI/O 42 41 TST1 TST0 IFDO IFCK DIN0 DIN1 DIN2 GND I2CS ERR RST VDD IFDI NC NC NC NC NC NC NC 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 65 LIN4 65 LIN3 66 LIN2 67 LIN1 68 RIN4 69 RIN3 70 RIN2 71 RIN1 72 NC 73 GNDAL 74 OUTL 75 VRAL 76 NC 77 VDALR 78 VRAR 79 OUTR 80 NC CS 19 kΩ 19 kΩ 19 kΩ 19 kΩ C1 C1 Lch input Mute SW MCU Interface Audio serial interface ELRI/O 40 SYNC 39 GNDR 38 500 Ω VDDR 37 Delay RAM NC 36 GNDA4 35 500 Ω DSP (I/O Interface) NC 34 Ch4 DAC circuit AI4 33 AO4 32 NC 31 BP C2 C2 C3 20 kΩ C3 C4 C4 VRAL Rch input Same as Lch input circuit Same as Ch1 DAC circuit 27 kΩ Ch3 DAC circuit Σ∆ ADC VRAL Lch circuit 15 kΩ 15 kΩ 15 kΩ Σ∆ DAC 15 kΩ 15 kΩ 15 kΩ Ch1 DAC circuit Ch2 DAC circuit Same as Ch1 DAC circuit AOT4 30 NC 29 VDA34 28 AOT3 27 20 kΩ 41.5 kΩ Same as Ch1 DAC circuit 8 kΩ AO3 26 AI3 25 BP 27 kΩ Same as Lch circuit Oscillator circuit 41.5 kΩ 7.8 kΩ GNDAR XO GNDX VDX NC NC NC NC NC AOT1 VDA12 AOT2 AI1 AO1 AO2 AI2 VRO1 NC GNDA1 GNDA2 VRO2 BP BP GNDA3 XI VRI 1 2 3 4 5 6 7 8 9 10 11 4 kΩ 12 13 14 15 16 17 18 19 20 21 22 23 24 3 2001-11-15 TC94A04AF/AFD Pin Functions Pin No. TC94A 04AF 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 TC94A 04AFD (Note 3) 2 3 4 5 7 8 9 11 13 14 15 17 18 20 21 23 24 25 26 27 28 30 32 33 35 37 38 39 Symbol I/O Function Remarks VDX XI XO GNDX GNDA1 AI1 AO1 AOT1 VDA12 AOT2 AO2 AI2 GNDA2 VRO1 VRI VRO2 GNDA3 AI3 AO.
