Description:
The ARM®Cortex®-M4 with FPU processor is the latest generation of ARM processors for embedded systems. With a low pin count and low power consumption, this processor provides a low-cost platform that meets the requirements of MCU implementations, while providing excellent computational
performance and advanced interrupt response.
The ARM® Cortex®-M4 processor with FPU core is a 32-bit RISC processor that offers excellent code efficiency and the high performance of the ARM core using the memory space of typical 8- and 16-bit devices. The processor supports a set of DSP instructions that enable efficient signal processing and complex algorithm execution. Its single-precision FPU (floating-point unit) accelerates development and prevents saturation through the use of meta-language development too.
It adopts a self-developed high-performance 32-bit MCU with a main frequency of up to 240M, which can easily drive a large screen;
It adopts the self-developed TK80 interface, backward compatible with the old 8080 interface, supports 1 to 24 bits, and can support 16 million color LCDs, and the display will no longer be distorted.
The 16MB QSPI FLASH used can put more pictures and fonts, and the comprehensive speed is 10 times higher than before; F4 chip with floating point unit FPU, which can support advanced functions of FPU part in emWin.
The chip's built-in memory is up to 8MB, no need to plug in an expensive 32-bit RAM, which saves core and money, has high integration and small space, and can easily run complex emWin interfaces.
Using USB to download the program, one data cable can download the program, and bid farewell to all kinds of LINK.
Built-in resistive touch service IP core, which can directly drive resistive touch without additional XPT2046 chip, which saves core and worry.
Support LTDC, support RGB888 (16 million colors), backward compatible with RGB666, 565, 555, etc.
The TF card adopts the hardware SDIO mode and cooperates with the efficient FATFS file system, which is much faster than the analog IO+SPI method.
