23 / 240 page  DocID024244 Rev 10 23/240 STM32F437xx and STM32F439xx Functional overview 43 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 • SAI1. 3.9 Flexible memory controller (FMC) All devices embed an FMC. It has four Chip Select outputs supporting the following modes: PCCard/Compact Flash, SDRAM/LPSDR SDRAM, SRAM, PSRAM, NOR Flash and NAND Flash. Functionality overview: • 8-,16-, 32-bit data bus width • Read FIFO for SDRAM controller • Write FIFO • Maximum FMC_CLK/FMC_SDCLK frequency for synchronous accesses is 90 MHz. LCD parallel interface The FMC 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 LCD-TFT controller (available only on STM32F439xx) The LCD-TFT display controller provides a 24-bit parallel digital RGB (Red, Green, Blue) and delivers all signals to interface directly to a broad range of LCD and TFT panels up to XGA (1024x768) resolution with the following features: • 2 displays layers with dedicated FIFO (64x32-bit) • Color Look-Up table (CLUT) up to 256 colors (256x24-bit) per layer • Up to 8 Input color formats selectable per layer • Flexible blending between two layers using alpha value (per pixel or constant) • Flexible programmable parameters for each layer • Color keying (transparency color) • Up to 4 programmable interrupt events. |
