Product details
Overview
DM860 from BridgeCo AG is a triple-core networked media processor integrating a 240MHz ARM926EJ system controller, a dedicated 160MHz secure co-processor for DRM encryption/decryption (AES, DES, RSA), and a real-time Audio Engine delivering >60 MIPS for WMA-lossless decoding and audio enhancement. It supports Ethernet MAC (10/100 Mbps), USB 2.0 OTG, I²S/I⁸S (up to 192 kHz), SPDIF (4 ports), and integrated TFT/STN/DSTN LCD controller - deployed in wired Internet Radio & Alarm Clocks and Networked Music Stations.
For engineers reviewing the DM860 datasheet, DM860 pinout, DM860 application, or DM860 equivalent, key selection criteria include its Wi-Fi–free architecture (vs. DM870), native NAND flash interface, dual UARTs (20 Mbps), on-chip RTC, and Linux 2.6–ready hardware abstraction layer supporting UPnP/DLNA middleware and premium music service integration.
Technical Context
The DM860 implements a tightly coupled triple-core architecture: the ARM926EJ handles OS execution and control tasks with 16KB I-cache/16KB D-cache; the Secure Processor offloads cryptographic operations including DTCP (5C), Elliptic Curve authentication, and proprietary content schemes; the Audio Engine executes SIMD-based parallel instruction sets for real-time signal processing without CPU intervention.
Hardware I/O acceleration includes MII/RMII Ethernet PHY interface with embedded 25 MHz clock generator, USB 2.0 OTG with 8 endpoints (INT/BULK/ISOCH), and DVB-SPI compliant 8-bit video I/O supporting MPEG/DV transport. Memory subsystem integrates 16-bit SDRAM controller (160 MHz), 256 MB SDRAM address space, and 64 KB on-chip SRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar networked audio processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DM870 | Includes integrated Wi-Fi baseband and MAC; otherwise identical CPU, Audio Engine, and Security Processor specifications. | Required when wireless connectivity must be implemented on-die; DM860 requires external Wi-Fi module. | Select DM870 only if Wi-Fi integration is mandatory and board space allows for RF layout complexity. |
| DM865 | Lower 150 MHz ARM926EJ clock speed; no Audio Engine; no TFT LCD controller; reduced I²S/SPDIF port count (1 vs. 4). | Suitable for cost-sensitive, lower-performance streaming clients without local GUI or real-time audio enhancement needs. | Choose DM865 only for basic UPnP audio renderers where WMA-lossless decode and color display are unnecessary. |
Compared with DM870, DM860 trades Wi-Fi integration for simplified RF design and lower EMI risk; compared with DM865, it delivers 60% higher CPU performance, full audio acceleration, and integrated display control - making it optimal for feature-rich, GUI-driven networked audio endpoints.

FAQ
What is the maximum supported SDRAM speed for the DM860?
The DM860 supports SDRAM operation at up to 160 MHz, enabling high-bandwidth media buffering for uninterrupted streaming of lossless audio formats. This specification is confirmed in the Hardware Description section of the product brief and matches the DM870's memory subsystem. The DM860 achieves this using a 16-bit data path with 256 MB address space, directly interfacing with industry-standard mobile SDRAM components without external glue logic.
Does the DM860 include an integrated Wi-Fi module?
No, the DM860 does not include an integrated Wi-Fi baseband or MAC. As explicitly stated in the Overview, it is functionally identical to the DM870 except for the omission of Wi-Fi functionality. Systems requiring wireless connectivity must implement an external Wi-Fi solution - such as a USB dongle or PCIe-based module - connected via the DM860's USB 2.0 OTG or Ethernet interfaces.
Which audio codecs are natively accelerated by the DM860's Audio Engine?
The DM860's dedicated Audio Engine provides hardware-accelerated real-time decoding of WMA-lossless, MP3, AAC, Real Audio, and WMA (including lossless variants), as documented in the Features and Software sections. It also supports audio enhancement functions like equalization, mixing, and sample rate conversion - all executed independently of the ARM926EJ core to preserve CPU resources for control and networking tasks.
What display resolutions does the DM860's integrated LCD controller support?
The DM860's integrated LCD controller supports TFT, STN, and DSTN panels up to 1024×768 resolution, as specified in the Hardware Description section. It outputs up to 18-bit RGB data and is designed for color graphical user interfaces in consumer audio products. Panel compatibility depends on achievable data rate and refresh rate - higher resolutions require careful timing configuration but do not necessitate external display controllers.
Is the DM860 compatible with Linux 2.6 and UPnP/DLNA standards?
Yes, the DM860 is fully compatible with Linux 2.6 and UPnP/DLNA standards. Its software stack includes a GPL-licensed Linux kernel with hardware-specific drivers, plus middleware supporting UPnP AV architecture, DLNA certification profiles, and TCP/IP stack implementation. Reference designs confirm end-to-end interoperability with certified media servers and renderers, enabling plug-and-play streaming in heterogeneous home networks.
