80-0274-E Datasheet, PDF (1/5 Pages) List of Unclassifed Manufacturers – VR Stamp™ With Serial EEPROM Speech Recognition Module

VR Stamp™
With Serial EEPROM
Speech Recognition Module
Data Sheet
Description
Sensory’s VR Stamp™ simplifies the design of
speech recognition products by integrating all key
components into a convenient 40-pin DIP footprint
module. A low-noise audio channel and standardized
footprint allow rapid prototyping, less debugging and
shorter time to market.
Using the VR Stamp™ Toolkit, application programs
can be downloaded into the VR Stamp. The VR
Stamp can then be removed from the Module
Programmer Board and plugged directly into the final
product. In-circuit reprogramming is also supported.
The VR Stamp offers 24 I/O lines, as well as
connections for a power, ground, microphone,
speaker, and logic-level RS232 interface.
