2 Functional Description
JTM010S recording recording chip module using external SPI memory JTM010 way to reach the recording function. Its main feature is the voice clear, long recording time. Currently the maximum recording time can be provided to 2730 seconds. A JTM010S notable feature is the storage flexible hours, the customer depending on the length of recording time to their needs, select the appropriate external SPI FLASH capacity, without having to change the main chip. JTM010S compared to other recording chip or circuit, it has a monolithic recording for a long time, multi-flexible control, low cost voice clear advantages.
JTM010 with key control mode, one button control mode and three-wire serial control mode, three modes. Can be easily applied in a variety of occasions, is highly cost-effective standardized recording module. JTM010S control mode only The first time the programming process is set, once again setting can not be changed, but the recording content can be freely rewritable.
