DocID022063 Rev 4

The DMA can be used with the main peripherals:

•

SPI and I2S

•

I2C

•

USART

•

General-purpose, basic and advanced-control timers TIMx

•

DAC

•

SDIO

•

Cryptographic acceleration

•

Camera interface (DCMI)

•

ADC.

2.2.9

Flexible static memory controller (FSMC)

The FSMC is embedded in the STM32F415xx and STM32F417xx family. It has four Chip

Select outputs supporting the following modes: PCCard/Compact Flash, SRAM, PSRAM,

NOR Flash and NAND Flash.

Functionality overview:

•

Write FIFO

•

Maximum FSMC_CLK frequency for synchronous accesses 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.

2.2.10

Nested vectored interrupt controller (NVIC)

The STM32F415xx and STM32F417xx embed a nested vectored interrupt controller able to

manage 16 priority levels, and handle up to 82 maskable interrupt channels plus the 16

interrupt lines of the Cortex™-M4F.

•

Closely coupled NVIC gives low-latency interrupt processing

•

Interrupt entry vector table address passed directly to the core

•

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.

2.2.11

External interrupt/event controller (EXTI)

The external interrupt/event controller consists of 23 edge-detector lines used to generate

interrupt/event requests. Each line can be independently configured to select the trigger
