ST STEVAL－CCM004V2 TFT LCD平板显示器控制方案

ST公司的STM32F20x系列是高性能的ARM® Cortex™-M3 32位RISC核MCU,工作频率高达120MHz,集成了高速嵌入存储器(闪存高达1MB,SRAM高达128KB),高达4KB备用SRAM,以及各种增强I/O和外设,连接到两个APB总线,三个AHB总线和32位多个AHB总线矩阵,主要应用在工业如PLC,逆变器,工业网络等;医疗电子如病人监护,手持医疗设备等;建筑物和安防系统如告警系统,HVAC,动力表等以及家用电器如三相马达驱动器,应用控制和用户接口等.本文介绍了STM32F20x主要特性和框图,以及用于STM3220F-EVAL的STEVAL-CCM004V2 TFT LCD平板显示器控制板的主要特性,电路图和材料清单.

The STM32F20x family is based on the high-performance ARM® Cortex™-M3 32-bit RISC core operating at a frequency of up to 120 MHz. The family incorporates high-speed embedded memories (Flash memory up to 1 Mbyte, up to 128 Kbytes of system SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.

The devices also feature an adaptive real-time memory accelerator (ART Accelerator™)which allows to achieve a performance equivalent to 0 wait state program execution from Flash memory at a CPU frequency up to 120 MHz. This performance has been validated using the CoreMark benchmark.
