Product Spec. Summary
SONIX SNM9S5XXXC2000A Decoder SoC:
■ Voltage operation range of sensor IC: 2.4 ~3.6V
■ OID decoder: Support dot pattern format:
■ Bi-direction communication via 2-wire interface
• Output Optical Index via two wire interface.
■Three Operation Modes
•Normal Mode
• Suspend Mode
- During Suspend Mode, the decoder SoC will keep all 2-wire commands and settings controlled by backend chipset, and will continue to work normally with the same settings after back to Normal Mode.
- Back to Normal Mode: 2-wire SCK 2us “HIGH” pulse.
•Configuration Mode
- Once 3.3V (VCC33) is provided, decoder SOC will stay in configuration mode initially.
- When be set to Normal Mode, an internal chip reset sets all settings to default values and starting work normally.
- Enter Normal Mode: 2-wire SCK 20ms ‘HIGH’ pulse (at least).
