GENERAL DESCRIPTION
Nuvoton’s ISD1900 ChipCorder® Series is a single-chip multiple-message record/playback device with dual operating modes and wide operating voltage ranging from 2.4V to 5.5V. The sampling frequency can be selected from 4 to 12 kHz via an external resistor, which also determines the duration. The device is designed for mostly standalone applications, and of course, it can be manipulated by a microcontroller, if necessary.
