Description: ISD4004系列工作电压3V,单片录放时间8至16分钟,音质好,适用于移动电话及其他便携式电子产品中。芯片采用CMOS技术,内含振荡器、防混淆滤波器、平滑滤波器、音频放大器、自动静噪及高密度多电平闪烁存贮陈列。芯片设计是基于所有操作必须由微控制器控制,操作命令可通过串行通信接口(SPI或Microwire)送入。芯片采用多电平直接模拟量存储技术, 每个采样值直接存贮在片内闪烁存贮器中,因此能够非常真实、自然地再现语音、音乐、音调和效果声,避免了一般固体录音电路因量化和压缩造成的量化噪声和"金属声"。采样频率可为 4.0,5.3,6.4,8.0kHz,频率越低,录放时间越长,而音质则有所下降,片内信息存于闪烁存贮器中,可在断电情况下保存100年(典型值),反复录音10万次。-ISD4004 series voltage 3V, single playback time of 8-16 minutes, good sound quality for mobile phones and other portable electronic products. Chip using CMOS technology, contains the oscillator, anti-aliasing filter, smoothing filter, audio amplifier, automatic squelch and high-density multi-level flash storage display. Chip design is based on all operations must be controlled by a micro-controller, the operation command through the serial communication interface (SPI or Microwire) into. Chip multi-level direct analog storage technology, the value of each sample directly stored in the flash memory chip, and therefore can be very real, natural reproduction of voice, music, tone and effect sound, solid recording circuit to avoid the general quantization and compression caused by quantization noise and the "metallic sound." Sampling frequency can 4.0,5.3,6.4,8.0 kHz, lower frequency, the longer the recorder, while the sound quality is down, piece of information stored in the flash memory Platform: |
