Category: Main/ II. Electronics components & Development Tools/II.3. Voice IC from Aplusinc and Nuvoton
| | | | | ◊ Đặc điểm chính: | |
aP23085 là chip phát nhạc mạnh mẽ, chỉ ghi nạp được dữ liệu nhạc 1 lần (OTP) bằng dùng mạch nạp aP23KWC8 của hãng. Chip có sơ đồ ứng dụng rất đơn giản, ít chân, chỉ cần cấp nguồn (2-5V) và có thêm 1 tụ lọc nguồn là chạy được. Chất lượng âm thanh phát ra rất tốt (đạt 16-bit), to rõ và có hỗ trợ kiểu nén ADPCM để tăng được thời lượng phát nhạc (2Mbit Flash). Đa dạng kiểu lệnh cho phát nhạc: kiểu phím bấm hoặc giao tiếp MCU...
Features:
● Standard CMOS process.
● Embedded 2M EPROM.
● 85 sec Voice Length at 6KHz sampling and 4-bit ADPCM compression.
● Maximum 1024 voice groups.
● Combination of voice blocks to extend playback duration.
● User selectable PCM16 or PCM8 or ADPCM data compression.
● 5 triggering modes are available :
◆ Key Mode ◆ CPU Parallel Mode
◆ I2C Mode ◆ SPI Mode ◆ MP3 Mode
● Voice Group Trigger Options: Edge/Level; Hold/Un-hold; Retrigger/Non-retrigger.
● Optional 16ms or 65us (@ 8KHz sampling rate) selectable debounce time.
● RST pin set to HIGH to stop the playback at once.
● LVR (Low Voltage Reset)
● 7 user programmable outputs.
● 3 kind oscillator : Internal-Rosc, External-Rosc, Crystal.
● 2V – 5V single power supply and < 5uA low stand-by current.
● PWM Vout1 and Vout2 drive speaker directly.
● D/A COUT pin drives speaker through an external BJT.
● 16 level Volume control.
● Audio out 16 bit.
● Development System support voice compilation.
