APR9600 is no longer manufacured and entered the obsolete parts list. APR9600 was a low cost high performance sound record/play IC widely used by embedded system practitioners, students, hobbyists.


The APR9600 provided all the necessary features for recording and playing the audio with very fewer external components at a very low cost. May be many of you are aware that the APR9600 audio recorder and playback IC is no longer manufacured!. The chip was manufactured by a Taiwan based company called APLUS Integrated Circuits Inc. I have searched for it in retail shops all across SP road Bangalore but the vendors said that the chip is no longer manufactured.


  • Single chip, high quality voice recording and playback solution
  • User friendly, Easy to use operation
  • Non - Volatile - flash memory technology, no battery backup required
  • 4-8 Khz sampling rate
  • Audio output to drive a speaker or audio out for public address system
  • Can record voice with the help of on-board microphone or via any audio input

The only place the APR9600 was available was at NSK electronics in Bangalore. Many of the projects i do require the sound recorder, so i contacted the APLUS Inc company support team. Their engineer had a skype conversation with me and told me that the APR9600 is no longer manufactured and suggested to use a similar but alternative part APR33A3 

Purchase/ buy APR9600 development kit in India at NSK electronics website at the price of Rs. 550 /-

APR9600 board is also available for purchase in India at Kits n Spares website at the price of Rs. 1050 /-
