Stm32 using sdram. If STM32 and SDRAM are BGA packages, 6 layers is the bare minimum that you need to route out the PCB properly without compromising on power or signal integrity. For that purpose, we will cover the configuration of the FMC Interface using the STM32 CubeMx Graphical tool and a simple example of accessing SDRAM using the FMC Interface. The FMC peripheral includes a lot of signals: there are data signals, address signals, read / write enable signals, “chip select” signals, and so on. Just for fun I looked for the maximum external memory configuration, which is SDRAM with 13-bit row address, 11-bit column address and 4 internal banks, giving 256MB memory (32-bit word length). 07 / drivers / ram / Just a small test of stm32f429 sdram + HAL + Cube. 1w次，点赞35次，收藏141次。目录一、SDRAM概述二、CubeMX配置三、程序配置一、SDRAM概述（内容参考正点原子 + 个人经验总结）STM32H743自带1M左右的RAM，虽然已经很大了，但总有不够的时候。RAM不够用，长久之计当然是增加外部RAM。外部RAM也分两大类，第一类是DRAM，另一类是SRAM。DRAM Example config Using SDRAM Links STM32F4 sdram configuration Here is some notes about playing with SDRAM.
