y Message and operation indicators
o Four customizable Sound Effects (SEs) for audible indication
o Optional vAlert (voiceAlert) to indicate the presence of new messages
o LED: stay on during recording, blink during playback, forward and erase operations
y Dual operating modes
o Standalone mode:
Integrated message management techniques
Automatic power-down after each operation cycle
o SPI mode:
Fully user selectable and controllable options via APC register and various SPI commands
y Two individual input channels
o MIC+/MIC-: differential microphone inputs with AGC (Automatic Gain Control)
o AnaIn: single-ended auxiliary analog input for recording or feed-through
y Dual output channels
o Differential PWM Class D speaker outputs directly drives an 8 speaker or a typical buzzer
o Configurable AUD (current) or AUX (voltage) single-ended output drives external audio amplifier
y ChipCorder standard features
o High-quality, natural voice and audio reproduction
o 2.4V to 5.5V operating voltage
o 100-year message retention (typical)
o 100,000 record cycles (typical)
