Introductions


On the STM32, up to now, it is possible interface two type of TFT color LCD that are:
  • TFT color LCD with controller on board via FSMC (Flexible Static Memory Controller)
  • QVGA TFT color LCD with no controller on board via FSMC (Flexible Static Memory Controller) plus some I/O pins
The max speed of FSMC depend of the type of STM32xxx that you use, for example:
  • STM32F103 @72Mhz max FSMC freq. is 30Mhz
  • STM32F2xx @168Mhz max FSMC freq. is 60Mhz
  • STM32F4xx @168Mhz max FSMC freq. is 60Mhz
Normally the FSMC is available from 100 pin package.

The STM32 flexible static memory controller (FSMC) is an embedded external memory controller that allows the STM32 microcontroller to interface with a wide range of memories, including SRAM, NOR Flash, NAND Flash and LCD modules.
The FSMC NOR Flash/SRAM bank is suitable for MCU parallel color LCD interfaces.


Below there is a table with the performances of STM32F103 and TFT color LCD with controller on board.
