ISD1900 Series ChipCorder
Nuvoton?s ISD1900 ChipCorder? is the newest single-chip multiple-message record/playback series
with dual operating modes (address trigger and direct trigger) and wider 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 from 10.6 to 32 seconds. These ICs are designed mostly for standalone
applications, and of course, it can be used in conjunction with a microcontroller, if necessary.
The two operating modes are address trigger and direct trigger. While in address trigger mode, both
record and playback operations are manipulated according to the start address and end address
specified through the start address and end address pins. However, in direct trigger mode, the device
can configure the memory up to as many as eight equal messages, pending upon the fixed message
configuration settings. With the record or playback feature being pre-selected, each message can be
randomly accessed via its message control pin.
The device has a selectable differential microphone input with AGC feature or single-ended analog
input, AnaIn, under feed-through mode. Its differential Class D PWM speaker driver can directly drive a
typical speaker or buzzer.
