Introduction The DM870 Core-2 module is a single-board networked media player module, based on BridgeCo’s DM870 media processor, and enables fast product developments with ethernet, WiFi and USB connectivity. The module connects to standard legacy components in various audio, video/LCD and control formats. It runs from a single 5V power supply and creates all the necessary voltages on the module. A stabilized 3.3V power is provided to the main board, to allow for further system cost reduction.

Differential stereo output from PWM-DAC. Low-active input to invoke the production BIST; DM870-internal pull-up Low-active input to invoke DM870 test mode; internal 10K pull-up High-active input to reset the configuration; DM870-internal pull-down Infrared sensor input. This is a Schmitt-Trigger input and can handle interrupt inputs with slow slopes. Low-active reset for the on-board ethernet phy. This output is driven by the DM870 and is not suited for other purpose. I2C bus created by GPIO-14 and GPIO-13. No internal pull-ups; if I2C is to be used, please add also the proper pull-up resistors. Voltage input to allow programming of DM870’s OTP. Leave unconnected for normal operation. Boot mode inputs. The module uses a 4K7 pull-up on FCLE and a 4K7 pulldown resistor to boot from the on-board NAND flash. Leave unconnected for normal operation. 3.3V push-pull outputs (max. ±12mA) to drive the ethernet LEDs. A low-level indicates 100Mbps mode and activity respectively.
