VR Stamp⢠Module - Serial EEPROM
Data Sheet
Microphone Ports
Input: The VR Stamp is designed so that you can use the on-board 1.2K microphone source resistor or external
custom microphone source resistor. Use the on-board microphone resistor if the microphone sensitivity provides
-49dB system gain with 1.2K. Use the external microphone source resistor otherwise. For more information on
microphones, refer to Design Note - Selecting a Microphone (80-0259).
NOTE: Sleep Current is 100uA (typ.) with a microphone.
Speaker Output (PWM0, PWM1)
Output: PWM ports can be directly connected to the speaker.
DAC Output
Output: An optional DAC output for the speaker is provided. To use DAC output, you need to provide the
external audio amplifier. Refer to page 4 of the Module Programmer Board Schematic (70-0069).
VR Stamp Schematic
Refer to: (70-0066).
Developing VR Stamp Applications
What you can develop with the VR Stamp:
Speaker Independent Recognition
Speaker Dependent Recognition
Speaker Verification
What you can not develop with the VR Stamp:
Record and Playback feature
Sample Programs
Sample programs in the FluentChip⢠Technology Library are a great place to start. Please refer to the RSC-4x
Module Programmer Board Manual (80-0294) for the complete list of supported samples.
Creating SI Recognition Sets and Speech Files
For creating Speaker Independent recognition sets, use âQuick T2SIâ¢-Lite (Pat. Pending)â
For creating speech files, use âQuickSynthesis 4â¢â
