Looking for a 1-minute Voice Chip with Self-Downloading and Sound Replacement?
If you're looking for a voice/audio playback chip with around 1 minute of storage that allows you to download and replace audio content yourself, then OTP-type chips (One-Time Programmable) on the market are not suitable. You'll need to use a Flash-type voice chip instead.
In this case, we recommend the KT148A (SOP8 package) voice chip, which can directly drive a 0.5W speaker. You can refer to the minimum system circuit for detailed hardware design.
