| 仕様: | ●ファミリー名 ： STM32F4●パッケージタイプ ： LQFP●実装タイプ ： 表面実装●ピン数 ： 144●デバイスコア ： ARM Cortex M4●データバス幅 ： 32bit●プログラムメモリサイズ ： 256 kB●最大周波数 ： 180MHz●RAMサイズ ： 128 kB●USBチャンネル ： 2●SPIチャンネル数 ： 4●USARTチャネルの数 ： 4●高さ ： 1.45mm●The STM32F446xC/E devices are based on the high-performance ARMRCortexR-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARMR single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The STM32F446xC/E devices incorporate high-speed embedded memories (Flash memory up to 512 Kbyte， up to 128 Kbyte of SRAM)， up to 4 Kbytes of backup SRAM， and an extensive range of enhanced I/Os and peripherals connected to two APB buses， two AHB buses and a 32-bit multi-AHB bus matrix. All devices offer three 12-bit ADCs， two DACs， a low-power RTC， twelve general-purpose 16-bit timers including two PWM timers for motor control， two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces. |
