For Pre-Recorded Voice Prompts
Internal oscillator with internal reference: 2.048 MHz with ±10% deviation
Internal oscillator with external resistor: 2.048 MHz with ±5% deviation when Rosc is 80k-ohm
External crystal or clock input
I
Crystals and resonators support standard audio sampling rates of 2.048, 4.096, 8.192, 12.288
and11.2896MHz
AUXIN: Analog input with 2-bit gain control configured by SPI command
ANAIN/ANAOUT:
Digital AGC:
PWM: Class D speaker driver to direct drive an 8 speaker or buzzer
AUDOUT: configurable as a current or voltage single-ended line driver
AUXOUT: a single-ended voltage output
BTL: a differential voltage output
SPI interface: MISO, MOSI, SCLK, SSB for commands and digital audio data
I
8 GPIO pins (4 of the 8 GPIO pins share with I
VOLA: volume control for the digital audio data from I
VOLB: volume control for the digital audio data from decompression block or SPI
VOLC: master volume control for PWM, AUDOUT, AUXOUT and I
Industrial: -40 C to 85 C

S bit clock input
S interface: I
µ-Law: 6, 7 or 8 bits per sample
Differential µ-Law: 6, 7 or 8 bits per sample
PCM: 8, 10 or 12 bits per sample
Enhanced ADPCM: 2, 3, 4 or 5 bits per sample
Variable-bit-rate optimized compression. This allows best possible compression given a
metric of SNR and background noise levels.
Analog input with the gain set by two external resistors from ANAOUT to ANAIN, or
Microphone differential input (ANAIN/ANAOUT becomes MIC+/MIC-)
Automatic gain control of digitized data from the analog input
