System on Module based on STMicroelectronics SPEAr1340

System on Module (SoM) based on new chip SPEAr1340 by STMicroelectronics was designed by Promwad to address growing demand in industrial grade SBC.

SPEAr1340 possesses exceptionally low power consumption, powerful CPU and GPU, rich set of interfaces and integrated periphery, making it an ideal choice for a wide set of graphics oriented industrial applications, both stationary and mobile.

Key applications of SPEAr1340 SoM:

  • GUI terminals (thin clients)
  • Industrial tablets
  • Surveillance systems
  • Video conference
  • Industrial controllers with GUI
  • HMI

The periphery of SPEAr1340 SoM

  • Two chips of DDR3 memory
  • One chip of NAND memory
  • MicroSD slot
  • Voltage regulators and power management, designed to run from a single 5V supply
  • Gigabit ethernet PHY
  • Mini PCIe for auxiliary periphery (e.g. Wi-Fi module)
  • Connector for LCD Touchscreen display

SoM complies with standard SO-DIMM 200 pins form factor. Motherboard contains no sensitive or high frequency circuits which greatly simplifies its design. Typical motherboard PCB has only two layers. For operating, SoM requires from motherboard only single 5V power supply.


The interfaces on the SoM-to-motherboard connector

  • HDMI video output with CEC support
  • 4 channel video camera interfaces
  • I2S interface for 7.1 audio codec
  • Analog video input (CVBS)
  • S/PDIF digital audio output
  • 4 PWM outputs
  • Port for 6x6 matrix keyboard
  • JTAG port
  • Gigabit Ethernet
  • General purpose interfaces: UART, SPI, I2C, GPIO, ADC
