VR Stamp™

With Serial EEPROM

Speech Recognition Module

Data Sheet

Description

Features

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.

FluentChip™ Capabilities

ꢀ Noise-robust Speaker Independent (SI) and

Speaker Dependent (SD) recognition

ꢀ Many language models now available for

international use

ꢀ High quality, 2.4-7.8 kbps speech synthesis &

sound effects with Sensory "SX" synthesis

technology

ꢀ Speaker Verification Word Spot (SVWS) -

Noise robust voice biometric security

ꢀ 8 voice MIDI-compatible music synthesis

ꢀ Audio Wakeup from sleep

ꢀ Touch Tone (DTMF) output

Integrated Solution

ꢀ RSC-4128 Speech processor & 1Mbit Flash

ꢀ 128Kb serial EEPROM for data

ꢀ 14MHz (main) & 32kHz (time keeping) clocks

ꢀ 24 I/O lines

ꢀ Microphone preamplifier

ꢀ Pulse Width Modulator (PWM) for Speaker

and optional DAC output

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.

Low Power Requirements

ꢀ V_DD= 2.70V – 3.6V

ꢀ I_ACT= 26mA @ 3V (typ. for complete module)

ꢀ I_SLEEP= <20uA @ 3V (typ. for complete

module)

The VR Stamp offers 24 I/O lines, as well as

connections for a power, ground, microphone,

speaker, and logic-level RS232 interface.
