These MCUs are ideal for low-cost networking applications. They integrate the IT800 power line modem developed by YITRAN, which provides communication over power lines using the 120 kHz to 400 kHz (FCC, ARIB) or 20 kHz to 80 kHz (CENELEC A) or 95 kHz to 125 kHz (CENELEC B) frequency band and achieves data transfer rates of up to 7.5 kbps. The MCUs can run a software library for the Data Link Layer (layer 2 of the OSI model) for “Protocol agnostic” solution. Maximum operating frequency is 15.36 MHz when using a PLL Synthesizer. A 64-pin package is available.

Key Features:

  • Data rate
    FCC/ARIB :
    7.5Kbps(SM : Standard mode)
    5.0Kbps(RM : Robust Mode)
    1.25Kbps(ERM : Extremely Robust Mode)
    CENELEC Indoor and Outdoor :
    2.5Kbps(RM : Robust Mode)
    0.625Kbps(ERM : Extremely Robust Mode)
  • Modulation
    High performance Spread Spectrum Technology (Differential Code Shift Keying- DCSK)
  • Adaptive rate control
    Transmission mode (data rate) is automatically selected, depending on channel condition.
  • Frequency Band
    FCC/ARIB: 100-400kHz
    CENELEC: 20-80 kHz(outdoor), 95-125 kHz(indoor)
  • Channel Access Protocol
    CSMA / CA
    (Carrier Sense Multiple Access / Collision Avoidance)
  • Resend
    Acknowledged and Unacknowledged
  • Area
    EU (European), Japan (Far East) and US (rest of the world)
