The aPR33A series C3.1 is Tape mode manages messages sequentially much like traditional
cassette tape recorders. Within tape mode two options exist, auto rewind and non-auto rewind.
Auto rewind mode configures the device to automatically rewind to the beginning of the message
immediately following recording or playback of the message. In tape mode, using either option,
messages must be recorded or played back sequentially, much like a traditional cassette tape
recorder specially designed for simple key trigger, user can record and playback the message.
Meanwhile, this mode provides the power-management system. Users can let the chip enter
power-down mode when unused. It can effectively reduce electric current consuming to 15uA and
increase the using time in any projects powered by batteries.
