Single voice chip solution in the phonetic system of secondary development is still the mainstream design strategy, little space usage, less peripheral devices, low failure rate of cloth plate, these advantages is self-evident. At present most of the single voice chips are OTP chips, only with the ability to one time burning and it is a kind of application block to those users who need to replace the voice frequently. According to the requirements of most customers, Shenzhen Waytronic Electronics Co. , Ltd has pushed out single voice chip WT588D08/16 which can be repeatable erasing voice contents. With strong editable ability, stable working performance, wide range of voltage, excellent quality, high cost performance, etc. Built-in 8M/16M FLASH_ROM, long storage time voice, times of repeatable erasing content is more than 50000 times. It is more suitable for secondary development and terminal applications.
WT588D08/16 can be used in a variety of automatic speech occasions, such as automotive electronics, station to station system, senior toys, intelligent home appliances, security system, voice detection system, etc.

Function Description
Key control mode is flexible to trigger and free to set any key to re-trigger. There are 15 trigger ways. Including trigger impulse repetition , trigger pulse without repetition , invalidation keys, no cycle Level , recycled level , non-maintained cycle level, non-cycle for the last one ,non-cycle for the next one , cycle for the last one , cycle for the next one, volume +, volume -, play / pause, stop, play / stop, etc. .
One-wire serial control mode and three-wire serial control mode, not only can control voice play, stop, loop play and volume size by the MCU, but also can direct triggering any voice in address bit from 0 to 219.
Application Range
Widely range of applications. It almost related to all the voice places, such as Stop devices announcer, reminder, alarm clock, learning machine, intelligent home appliances, therapeutic equipment, electronic toys, telecommunications, reversing radar and a variety of automatic control devices, etc. Technology meets up to the requirements of industries application.
