STM32F20xxx
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.
Functional overview

Flexible static memory controller (FSMC)
The FSMC is embedded in all STM32F20x devices. 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
• Maximum frequency (f_HCLK) for external access is 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.
3.10
Nested vectored interrupt controller (NVIC)
The STM32F20x devices embed a nested vectored interrupt controller able to manage 16
priority levels, and handle up to 81 maskable interrupt channels plus the 16 interrupt lines of
the Cortex™-M3.
The NVIC main features are the following:
• Closely coupled NVIC gives low-latency interrupt processing
• Interrupt entry vector table address passed directly to the core
• Closely coupled NVIC core interface
• Allows early processing of interrupts
• Processing of late arriving, higher-priority interrupts
• Support tail chaining
• Processor state automatically saved
• Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimum interrupt
latency.
