1 / 63 page FEDL228XX-05 Issue Date: Oct. 10, 2013 ML2282X-XXX/ML2286X-XXX Speech Synthesis LSI with Built-in P2ROM Including 2-Channel Mixing Function 1/63 GENERAL DESCRIPTION ML2282X(ML22825/ML22824/ML22823-XXX) and ML2286X (ML22865/ML22864/ML22863-XXX) are voice synthesis LSIs with built-in P2ROM that stores speech data. These LSIs include edit ROM, ADPCM2 decoder, 16-bit DA converter, low pass filter and monaural speaker amplifier. Also, ML2282X supports the synchronous serial interface and ML22865/ML22864/ML22863 supports the I2C interface. By integrating all the functions required for voice output into a single chip, these LSIs can be more easily incorporated in compact portable devices. • Built-in memory capacity and maximum vocal reproduction time: (at the case of 4-bit ADPCM2 algorithm) Maximum vocal reproduction time (sec) Product name ROM capacity FS = 4.0 kHz FS = 8.0 kHz FS = 16 kHz ML22825-XXX/ML22865 16 Mbits 1,044 522 261 ML22824-XXX/ML22864 8 Mbits 520 260 130 ML22823-XXX/ML22863 4 Mbits 258 129 64 • Voice synthesis method: 4-bit ADPCM2 8-bit Nonlinear PCM 8-bit PCM , 16-bit PCM Can be specified for each phrase. • Sampling frequency(Fs): 4.0 / 5.3 / 6.4 / 8.0 / 10.6 / 12.0 / 12.8 / 16.0 / 21.3 / 24.0 / 25.6 / 32.0 / 48.0 kHz fs can be specified for each phrase. • Built-in low-pass filter and 16-bit DA converter • Speaker driving amplifier: 0.7 W (when 8 Ω , DV DD=5 V, Ta=25°C) 2ch analog input (internal: 1ch; external: 1ch) • CPU command interface: 3-wired serial clock-synchronized (ML2282X) I2C interface (ML2286X) • Maximum number of phrases: 4,096 phrases from 000h to 3FFh (1024 phrases/bank) • Memory bank switching: Enabled between bank 1 and bank 4 using the SEL0 and SEL1 pins • Volume control: 32 levels (OFF is included) can be set by CVOL command. 50 levels (OFF is included) can be set by AVOL command • Repeat function: LOOP commands • 2-channel mixing function: Available except case using 32kHz as sampling frequencys • Source oscillation frequency: 4.096 MHz • Power supply voltage: 2.7 to 3.6V / 4.5 to 5.5 V • Operating temperature range: –40 to +85 °C • Package: 30-pin plastic SSOP (SSOP30-P-56-0.65-K-MC) • Product name: ML22825-xxxMB, ML22824-xxxMB, ML22823-xxxMB ML22865-xxxMB, ML22864-xxxMB, ML22863-xxxMB (xxx: ROM code No.) |
