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.

Nuvoton ARM Video SoC  가 있다.

 

200Mhz 의 CPU이고 내부에 DDR 메모리가 있다. 그외에 LCD 인터페이스도 있다.

LQFP package 여서 아트웍도 편리할듯 ..

 

NUVOTON 에서 나오는 5V Cortex-M0 MCU

 

가격만 적당하면 쓸만 할듯 ..

LPC4357 은 NXP 에서 나온 MCU 다

특이한 점은 Cortex-M4와 M0 가 같이 들어가있는 멀티 코아 MCU 라는 것이다.

ICBANQ에 다음과 같은 기사가 있어서 해당 내용을 확인 하기 위해

http://www.icbanq.com/ELECINFO_NET/Elec_SemiProd_Detail.aspx?number=5577

 

element14에 가보았다.

http://www.element14.com/community/docs/DOC-51065?ICID=knode-nxpmm-space

 

LCD 없는 제품 가격이 108.063원

LCD 있는 제품 가격이 133,000 원

 

훅 땡긴다. 사볼까 고민 중
