STM32H7 HDMI Board SODIMM Module is an SDRAM memory module designed to work with the STM32H7 HDMI Board. It provides 512 MB of SDRAM memory supporting a maximum memory clock frequency of 200 MHz, and exposes a 32-bit data bus for full compatibility with the STM32H747 FMC (Flexible Memory Controller) used in the STM32H7 HDMI Board. The SODIMM Module follows the JEDEC 144-pin SODIMM pin assignment with only half of the data bus implemented (32 bits). It also features an EEPROM memory chip for Serial Presence Detect. The board dimensions comply with the MO-190-C SODIMM Mechanical Specifications.
