STM32F4 System-on-Module (SOM-STM32F4)

The Emcraft Systems STM32F4 System-On-Module (SOM) is a compact (30 mm x 46 mm) mezzanine module that combines a 180 MHz Arm Cortex-M4 STM32F429 microcontroller with 32 MB SDRAM, 16 MB NOR Flash and an Ethernet PHY buffer on a single board. The SOM interfaces to a baseboard (motherboard) using two 80-pin interface connectors.

The following are the key hardware features of the STM32F4 SOM:

• Compact (30 mm x 46 mm) mezzanine module;
• External interface using two 80-pin 0.4 mm-pitch connectors;
• Mounting hole reducing the risk of connector-to-PCB intermittence;
• Compliant with the Restriction of Hazardous Substances (RoHS) directive;
• STM32F429 MCU in UFBGA176 package capable of running the system clock at up to 180 MHz;
• Arm SWJ-DP: a combined JTAG and serial wire debug port;
• Powered from single +3.3 V power supply;
• Low-power mode with short startup times;
• Deep-sleep power mode with ultra-low power consumption profiles;
• On-module clocks;
• 32 MBytes SDRAM;
• 16 MBytes NOR Flash;
• Serial console interface at UART CMOS levels;
• 802.3 Ethernet interface;
• USB 2.0 full-speed device/host/OTG controller with on-chip PHY;
• Watchdog Timer (WDT);
• Real-Time Clock (RTC);
• All otherwise uncommitted interfaces of the STM32F4 MCU available on the interface connectors.
