HOW TO WRITE A VOICE TO AN ISD1820PY CHIP
Your voice or other audio information can be easily recorded in the ISD1820 chip without special devices and even with a minimum of details.

You can record from a smartphone, phone, microphone, or even a speaker or sound column.
The inputs of the chip are better protected with small capacitors of 0.01 UF (pins 4.5). the write resolution input (1) must be supplied with a positive potential from the power bus (possible without a resistor). The duration of recording depends directly on the value of the resistance between the pin (10) and the negative power bus.
When writing to fill the memory buffer, the process stops. Further, by applying a positive potential to the pin (2) and having a connected speaker to the pins (7,9), you can once listen to a fragment recorded in the chip.
To repeat " by applying a positive potential to the output (2)"
That's it!
