DM870-TE

The DM870-TE is an ARM926EJ-based 32-bit microprocessor running at 240 MHz, designed for embedded media and networked applications. It combines a system controller core with dedicated multimedia and security co-processors and provides integrated interfaces for display, networking and storage to support consumer and networked media devices.

Key Features

• Core Processor – ARM926EJ 32-bit RISC core, single-core operation at 240 MHz for control and application tasks.
• Multimedia and Security Co-processors – On-chip co-processors for multimedia (Audio Engine) and security/real-time secure processing to offload compute-intensive audio and DRM-related functions.
• Memory Controllers – Integrated SDRAM and SRAM controllers to support system and application memory needs.
• Display and Graphics – Integrated LCD controller plus graphics acceleration to drive color graphical user interfaces on TFT/STN/DSTN panels.
• Networking and I/O – 10/100 Mbps Ethernet and general-purpose I/O (GPIO) for wired networked applications and board-level control.
• USB – USB 2.0 OTG (1) for host/device connectivity and peripheral interfacing.
• Storage and Expansion – On-chip interfaces commonly used in the DM870 family such as SD/SDIO/MMC and native NAND flash support (as found in the DM870 platform documentation).
• Package and Mounting – 292-LFBGA package (17 × 17 mm), surface-mount for compact board designs and automated assembly.
• Environmental Compliance – RoHS compliant.

Typical Applications

• Internet Radio & Alarm Clocks – Networked streaming playback, local UI and audio processing for Internet radio devices and alarm clocks.
• Networked Music Stations – Stand-alone music players and streaming stations that require integrated audio decoding, DRM-aware playback and network connectivity.
• Consumer Audio / AV Devices – Integration into mini-hi‑fi systems, AV receivers and docking stations that need Ethernet, USB OTG and display support.

Unique Advantages

• Integrated multimedia processing – Dedicated audio engine and multimedia co-processors reduce CPU load and simplify audio pipeline implementation.
• Consolidated system interfaces – Built-in Ethernet, USB OTG, LCD controller and GPIO reduce external controller count and BOM complexity.
• Flexible memory support – SDRAM and SRAM controllers plus native NAND/SD interfaces (platform-level) enable scalable storage and memory architectures.
• Compact, production-ready package – 292-ball LFBGA (17×17 mm) surface-mount package supports high-density system designs and automated assembly.
• Compliance and manufacturability – RoHS compliance aligns with common environmental requirements for consumer electronics production.
