ST 에서 나온 SDRAM,TFT LCD 연동 MCU
나름 속도도 빠르고 좋다 UCLINUX 도 잘 돌거 같고 ..
하지만 adstar와 비교해봐야 겠다. 성능대비 가격이 만족 할까 하는 생각이 든다.
The STM32F429xx devices is based on the high-performance ARM®Cortex™-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 ARM 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 Cortex-M4 core with FPU will be referred to as Cortex-M4F throughout this document.
The STM32F429xx devices incorporates high-speed embedded memories (Flash memory up to 2 Mbyte, up to 256 Kbytes 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. a true random number generator (RNG). They also feature standard and advanced communication interfaces.
