DH Electronics' DHCOM STM32MP1 Offers Three Arm Cores, a 3D GPU, and More on a SODIMM Module

Low-power module is a drop-in replacement for older DHCOM boards, and will be produced for the next decade at a minimum.

DH Electronics has launched a new system-on-module (SOM), the DHCOM STM32MP1, which offers two Arm Cortex-A7 and one Arm Cortex-M4 cores plus a 3D-capable Vivante GPU on compact SODIMM-format module — and has designed a pico-ITX-format carrier board for it, too.

Brought to our attention by CNX Software, the new DH Electronics DHCOM STM32MP1 is — as the name suggests — built around STMicroelectronics' STM32MP15x system-on-chip, offering two Arm Cortex-A7 processor cores running at 650MHz and a 209MHz Arm Cortex-M4 coprocessor for real-time tasks, along with a Vivante 3D-capable graphics processor running at up to 533MHz.

The compact SOM includes 256MB, 512MB, or 1GB of DDR3 memory, 4GB, 8GB, or 16GB of eMMC flash storage alongside a 2MB boot flash and 256-byte EEPROM, plus an on-module micro-SD socket for additional storage. 802.11a/b/g/n, 802.11j, and Bluetooth 5.0 including Bluetooth Low Energy (BLE) communications are included via an on-board PCB antenna or optional externally-connected antenna, and there's Arm TrustZone support for security.

The 200-pin SODIMM-format connector at the module's base includes a 4-bit SD Card interface, 24-bit RGB interface supporting up to 1366x768 resolution, two lanes of MIPI Display Serial Interface (DSI), a four-wire touch interface, a 10-bit parallel camera interface, 10/100 Ethernet, USB host and USB OTG, I2S, two CAN buses, three UARTs, SPI, two I2C, 24 general-purpose input/output (GPIO) pins, 16-bit pulse width modulation (PWM), two 16-bit analog-to-digital converter (ADC) pins, and two 12-bit digital-to-analog converter (DAC) pins.

DH Electronics has rated the part for a wide operating temperature of -40 to 85°C (around -40 to 185°F), and claims the industrial-ready part is drop-in compatible with other DHCOM modules and will be produced for at least 10 years.

More information on the board is available on the official product page, while a pico-ITX carrier board is also available; the company has not yet published pricing information.
