DMA
The flexible 16-stream general-purpose DMAs (8 streams for DMA1 and 8 streams for
DMA2) are able to manage memory-to-memory, peripheral-to-memory and memory-to-
peripheral transfers. They share some centralized FIFOs for APB/AHB peripherals, support
burst transfer and are designed to provide the maximum peripheral bandwidth (AHB/APB)
and performance.
The two DMA controllers support circular buffer management, so that no specific code is
needed when the controller reaches the end of the buffer. The two DMA controllers also
have a double buffering feature, which automates the use and switching of two memory
buffers without requiring any special code.
Each stream is connected to dedicated hardware DMA requests, with support for software
trigger on each stream. Configuration is made by software and transfer sizes between
source and destination are independent.
The DMA can be used with the main peripherals:
SPI and I2S
I2C
USART and UART
General-purpose, basic and advanced-control timers TIMx
DAC
SDIO
Camera interface (DCMI)
ADC.

FSMC (flexible static memory controller)
The FSMC is embedded in the STM32F205xx and STM32F207xx family. It has four Chip
Select outputs supporting the following modes: PC Card/Compact Flash, SRAM, PSRAM,
NOR Flash and NAND Flash.
Functionality overview:
Write FIFO
Code execution from external memory except for NAND Flash and PC Card
The targeted frequency, fCLK, is equal to HCLK/2, so external access is at 60 MHz
when HCLK is at 120 MHz and external access is at 30 MHz when HCLK is at 60 MHz
LCD parallel interface
The FSMC can be configured to interface seamlessly with most graphic LCD controllers. It
supports the Intel 8080 and Motorola 6800 modes, and is flexible enough to adapt to
specific LCD interfaces. This LCD parallel interface capability makes it easy to build cost-
effective graphic applications using LCD modules with embedded controllers or high
performance solutions using external controllers with dedicated acceleration.
