MPN: DC-ME-Y402-C ✓ Hoạt độngDC-ME-Y402-C Tóm tắt
What is a System-on-Module (SOM)? A SOM is a small, pre-integrated computing module that combines a processor, memory, and key peripherals on a single board, designed to plug into a carrier board via a standardized high-density connector. SOMs belong to the broader category of embedded computing modules (subclass of embedded modules, within computer-on-module / CoM taxonomy), enabling OEMs to add complex functionality - here, secure networking - without designing the SoC hardware themselves. For engineers designing connected products, the DC-ME-Y402-C collapses the hardware stack of a 32-bit ARM9 networking node into a footprint suited for retrofit and new product designs.
Key specifications include an ARM926EJ-S core (NS9210) at 75 MHz, 8 MB SDRAM, 4 MB on-module flash, 10/100 Mbps Ethernet, and an industrial operating temperature range of -40C to +80C. The module exposes the NS9210 peripheral set through the standard Digi Connect ME 9210 60-pin SMT connector, enabling reuse of existing carrier boards across the family. According to Digi product documentation, the DC-ME-Y402-C ships as a single-unit pack with NET+OS firmware support.
The DC-ME-Y402-C uses the Digi NET+OS development environment, including the Platform object library, ThreadX RTOS-based runtime, and the Digi ESP IDE. Power input is 3.3 V typical via the carrier connector, and the module integrates the PHY magnetics center-tap requirements on-module, simplifying host board design.
Typical applications include industrial automation gateways, building automation controllers, medical device networking, retail/POS terminals, and security/access control panels. Anywhere a 32-bit wired Ethernet node with a secure RTOS stack is needed, the DC-ME-Y402-C accelerates time-to-market.
Design consideration: a critical design factor is the carrier board layout - the high-density 60-pin SMT connector footprint and routing constraints must be observed. The DC-ME-Y402-C shares its family footprint with other Connect ME 9210 variants, enabling migration paths without PCB rework.

Ứng dụng tiêu biểu
DC-ME-Y402-C phù hợp cho 6 Áp dụngs: Industrial Automation Gateways, Building Automation Controllers, Medical Device Networking, Retail POS and Kiosk Terminals, Security and Access Control Panels, Energy and Smart-Grid Submeters.
Industrial Automation Gateways
The DC-ME-Y402-C is well-suited to industrial automation gateways thanks to its 75 MHz ARM926EJ-S NS9210 core, integrated 10/100 Ethernet MAC/PHY, and -40C to +80C industrial operating range. Its NET+OS firmware supports industrial protocols such as Modbus/TCP and EtherNet/IP, enabling bridge designs between legacy serial field devices and modern TCP/IP networks. The module's 8 MB SDRAM and 4 MB flash accommodate protocol stacks plus web-based management UIs. Unlike full custom designs, the DC-ME-Y402-C's pre-certified 60-pin SMT carrier interface accelerates EMC compliance work for industrial control panels.

Building Automation Controllers
In building automation, the DC-ME-Y402-C serves as a wired IP node connecting HVAC, lighting, and access-control subsystems to BACnet/IP or HTTP-based management dashboards. Its 10/100 Ethernet MAC/PHY handles 100 Mbit full-duplex backbone traffic for typical room-controller loads, while the ARM926EJ-S core runs NET+OS ThreadX-based real-time scheduling needed for deterministic BACnet timing. The 8 MB SDRAM supports TLS-encrypted management sessions. Per Digi Connect ME 9210 family documentation, the module's industrial temperature range tolerates plant-room environments without active cooling.
Được đề xuất
Medical Device Networking
The DC-ME-Y402-C enables secure network connectivity for medical devices such as patient monitors, infusion pumps, and diagnostic instruments. Its ARM926EJ-S NS9210 with MMU supports the NET+OS secure networking stack, providing TLS, HTTPS, and SSH for HIPAA-compliant data transport. The 8 MB SDRAM is sufficient for TLS session buffers and modest on-device data logging. The -40C to +80C industrial temperature range tolerates equipment-room deployments. Note: medical end-product FDA/IEC 60601-1 qualification remains the OEM's responsibility; the DC-ME-Y402-C is the connectivity subassembly only.

Retail POS and Kiosk Terminals
Retail point-of-sale (POS) terminals and self-service kiosks benefit from the DC-ME-Y402-C's compact Connect ME 9210 footprint and integrated Ethernet. The 75 MHz ARM926EJ-S core runs NET+OS with web-server and TCP/IP stack support, enabling remote price-update, inventory sync, and EFT transaction transport over a wired LAN. The 4 MB flash accommodates firmware images, while 8 MB SDRAM handles TLS handshake buffers. The module's single-unit pack option suits low-volume specialty retail deployments where a full custom SBC is overkill.

Security and Access Control Panels
Security panels, door controllers, and surveillance aggregators deploy the DC-ME-Y402-C as a wired TCP/IP gateway between access-control readers and central management software. Its ARM926EJ-S core at 75 MHz runs NET+OS with support for HTTPS, RADIUS, and LDAP-based authentication. The integrated 10/100 Ethernet MAC/PHY provides a reliable backhaul, and the -40C to +80C temperature range suits outdoor enclosures. The 60-pin SMT standard footprint enables PCB reuse across the Connect ME 9210 family, including migration to later DC-ME-Y402-S-UPW variants with Ripple20/Treck security patches.

Energy and Smart-Grid Submeters
Smart-grid submetering and energy-monitoring applications use the DC-ME-Y402-C as an IP-based data concentrator. Its ARM926EJ-S NS9210 with NET+OS supports DLMS/COSEM, IEC 61850, or MQTT-over-Ethernet protocols for upstream AMI backhaul. The 75 MHz CPU headroom handles 50-100 simultaneous meter polling sessions with TLS encryption. The 8 MB SDRAM accommodates TLS session memory and protocol stacks, and the industrial -40C to +80C operating range covers outdoor cabinet installations. The module's small footprint fits inside meter enclosures without re-engineering.

Ghi chú thiết kế
Estimated: The Connect ME 9210 60-pin SMT connector requires careful host-board layout. Per the Digi Hardware Reference Manual, keep the carrier-board SMT land pattern within Digi's published mechanical tolerance, route Ethernet differential pairs (TX+/TX-, RX+/RX-) as 100-ohm differential with matched length, and place the 3.3 V decoupling capacitors within 5 mm of the module pins. The on-module PHY magnetics center-tap is provided internally, but the host board must include the 49.9-ohm 1% termination resistors and Bob Smith termination for proper EMC performance.
Estimated: at 3.3 V supply and typical 75 MHz operation with Ethernet active, the DC-ME-Y402-C consumes approximately 200-300 mA. The host carrier should provide a low-noise 3.3 V LDO or DC-DC regulator capable of at least 500 mA with 50 mV peak-to-peak ripple. Add bulk 47 uF + 10 uF ceramic + 0.1 uF ceramic bypass network near the module power pins to suppress NET+OS peak current transients during Ethernet frame transmission.
Do not confuse the DC-ME-Y402-C with the older Connect (non-9210) modules - the NS9210 silicon is ARM926EJ-S class with MMU, while the legacy Connect uses ARM7TDMI without MMU. Firmware images are NOT binary-compatible across generations. Additionally, per Digi PCN#191204-01, new designs should specify DC-ME-Y402-S-UPW with firmware revision P or newer to receive the Treck/Ripple20 security fixes - the original DC-ME-Y402-C firmware has unpatched vulnerabilities.
Estimated: the DC-ME-Y402-C at 75 MHz with active Ethernet dissipates roughly 0.7-1.0 W into the carrier board. The module's -40C to +80C operating range assumes adequate host-board copper area (at least 1 square inch of unbroken ground pour) for heat spreading. For sealed IP65/IP67 enclosures, validate with a thermal chamber that the module's internal junction temperature stays below 95C at ambient +80C, since the small SOM has limited surface area for convection cooling.
