# DCB1M-IC (Component) ## Description 225k ~ 1.4M Modem PSK 32-QFN (5x5) The DCB1M is a device for multiplex communication over noisy power lines, at speed up to 1.4Mbit/s. The DCB1M is based on the DC-BUS™ technology for network communication between modules sharing a common DC or AC powerline. The device avoids complex cabling, saves weight, and simplifies installation. The DCB1M supports UART, SPI, DMX512, RDM, and I 2C protocols, enabling the user to meet this application protocol. Sleep mode allows low power consumption when the device is not used. A QFN32 5x5 mm package provides a small PCB footprint The DCB1M is beneficial for many applications ranging from LED, Aerospace, Automotive, Industrial, and even Toys. Features • Noise robust UART, SPI, DMX512, RDM, and I2C transceiver over DC powerline. • Bitrate up to 1.4Mbit/s over the powerline. • Multiple networks may operate over a single powerline. • 251 selectable carrier frequencies (5MHz to 30MHz). • Built-in CSMA/CA (powerline arbitration) mechanism. • Operates as Multi-master Transceiver in a multiplex network. • Channel interference detection. • Communicates over a wide range of DC voltages. • Power management (Sleep modes) for low power consumption. ## Component Details - **Owner:** adrian95 - **Created:** 6/18/2026 - **Last Updated:** 6/18/2026 - **Visibility:** Public - **Manufacturer Part Number:** DCB1M-IC - **Part Type:** Integrated Circuit - **Symbol Style:** parametric-v1 - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/7a071f9617298535d979d276d585628105774a7cced1257fe573fd09032446f7.pdf - **Manufacturer Name:** Yamar - **License:** https://creativecommons.org/licenses/by/4.0/ - **Part Type:** Integrated Circuits - **Sub-Type:** Logic - **MPN:** DCB1M-IC - **Mount Type:** PCB - **Package / Case Code:** 32-QFN - **Pin Count:** 33 - **Logic Function:** AND ## Pins | Pin | Name | Type | |-----|------|------| | 1 | TEST | | | 2 | NRESET | | | 3 | VCAP | | | 4 | DGND | | | 5 | DVCC | | | 6 | HDC /HCS | | | 7 | HDO | | | 8 | HDI | | | 9 | IF_SEL1 | | | 10 | IF_SEL0 | | | 11 | INT/RTR/ FREQ_SEL_2 | | | 12 | CODE_SEL1 /BUS_BUSY /FREQ_SEL_1 | | | 13 | CODE_SEL0 /EN_TX /INTERF /FREQ_SEL_0 | | | 14 | DVCC | | | 15 | SCK /NLOOPBACK/NC | | | 16 | TXON | | | 17 | NSLEEP | | | 18 | INH | | | 19 | SPIHD | | | 20 | FILTERO | | | 21 | VREF | | | 22 | AGND | | | 23 | SPID | | | 24 | RXI | | | 25 | AVCC | | | 26 | GPIO19 | | | 27 | L1 | | | 28 | AGND | | | 29 | PLLCAP | | | 30 | XTAL_P | | | 31 | OSCI | | | 32 | OSCO | | | 33 | GND | | --- *Generated from [https://www.flux.ai/adrian95/dcb1m-ic~tvq](https://www.flux.ai/adrian95/dcb1m-ic~tvq)*
