STM32F20xxx

Functional overview

177

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.

3.9

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 (fHCLK) 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.
