Shanghai Hanchuan Technology has tailored a high-performance, high-reliability solution for Industrial Internet of Things (IoT) gateways, edge computing nodes, and complex industrial control devices – the SAM-M3100A core board.
It is powered by the NXP i.MX 6ULL application processor, based on the efficient ARM Cortex-A7 core, with a maximum frequency of up to 900MHz.
Key highlights of the processor:
True industrial-grade quality: It can operate stably at junction temperatures ranging from -40°C to 85°C! Whether in cold outdoor environments or hot factory workshops, it can work reliably. This is thanks to its industrial-grade reliability and wide temperature design.
Built-in security fortress: Security for IoT devices is crucial. The i.MX 6ULL includes a security module with a true random number generator (TRNG), an AES encryption engine supporting differential power analysis (DPA), TDES/SHA/RSA algorithms, tamper monitoring, and secure boot functionality. This provides hardware-level security for end devices.
Integrated power management (PMIC): The processor integrates a PMIC module, significantly simplifying your peripheral power design challenges and costs, making the system power-up sequence more reliable.
The 48x35mm board integrates 512MB of DDR3 memory and 8GB of eMMC flash storage, providing ample operating space and storage capacity for applications and operating systems (primarily Linux). It boasts fast boot speeds and smooth operation.
The SAM-M3100A features an extremely rich set of interface resources, unlocking nearly all the potential of the i.MX 6ULL through two high-density 0.8mm pitch 160Pin connectors (2x80Pin):
Dual 100Mbps Ethernet (ENET1 & ENET2): Supports the IEEE 1588 protocol, easily building industrial network communication nodes for precise clock synchronization.
Dual USB 2.0 OTG with PHY: Both ports come with PHY chips! One can be configured as OTG (convenient for programming and debugging), while the other defaults to HOST, or both can be set as hosts, making it very convenient to connect peripherals. The integrated PHY means simpler baseboard design.
Up to 8 UART serial ports! One is commonly used for debugging, while the remaining 7 can connect various serial devices such as PLCs, sensors, HMIs, etc., addressing the pain points of multi-device communication.
Dual FlexCAN: Fully supports the CAN 2.0B protocol, making it an ideal choice for industrial field buses (such as CANopen, DeviceNet), connecting motor drives, controllers, etc.
Powerful multimedia capabilities: One 24-bit parallel CSI camera interface supports up to 24-bit RGB/YUV input, easily interfacing with industrial cameras. One parallel LCD interface supports a maximum resolution of WXGA (1366×768), effortlessly driving large industrial displays.
Flexible audio and video interfaces: Provides 3 SAI/I2S interfaces that can connect to audio codec chips, supporting I2S, AC97, TDM, etc., meeting voice interaction or audio playback needs.
Rich expansion interfaces: 4 I2C buses, 4 SPI buses, up to 8 PWM outputs for precise control of motors, LED brightness, etc. 2 12-bit ADCs (10 channels total), with one configured by default for resistive touch screen (4-wire/5-wire) interfaces. There are also 2 SDIO interfaces (one occupied by the onboard eMMC, the other exposed), SIM card interface, etc.
Ample GPIO: The CPU provides up to 100 IOs (specific available numbers need configuration), meeting your various digital signal input and output needs through multiplexing.
High integration and ease of use are another key advantage. All major components – CPU, memory, storage, basic power management – are integrated on this postage stamp-sized board. You only need to design a baseboard to carry it and connect the required peripherals (such as Ethernet PHY, display, sensors, etc.), and a powerful embedded system takes shape, significantly shortening your product development cycle.
In summary, the SAM-M3100A core board is a competitive product that combines industrial-grade wide temperature, hardware security, rich interfaces (dual Ethernet ports, 8 serial ports, dual CAN, LCD/CSI, multiple USBs, etc.), and high integration. If you are looking for an embedded core that can operate stably in harsh environments, has strong connectivity, and simplifies design, the SAM-M3100A is definitely a choice you can trust!
