SG3D Series Short-distance Voice ICs
- PRODUCTS
- ASIC Design
Introduction:
The SG3DXX series is speech synthesis series chip which with 6 seconds (at 6KHz play rate) single-channel voice and dual channel melody output. The chip integrates a microcontroller, two timers, two I/O ports, a sound sensor, and a short-range communication module. By programming the microcontroller, the user can implement the following functions: voice segment combination, trigger mode control, output state control, high performance melody, and voice output with background melody. In particular, the user can realize sound control triggering through the built-in sound sensor, and realize communication and interaction between toys through the short distance communication module.
Feature:
- Wide operating voltage range(1.8V to 5.5V)
- Built-in a PWM driver circuit
- PWM drive current can select OFF, 30mA, 60mA, 120mA by programming
- Single channel speech synthesizer
- Dual channel melody synthesizer
- Melody volume is adjustable
- Built-in sound sensor
- Built-in short-distance communication, modulation and demodulation function
- Carrier frequency 10KHz/20KHz is optional
- Built-in charge pump to supply power to the emitter stage
- Output voltage of charge pump: 2V-0.6V
