PIC24 USB Host Controller

PIC24 USB Host Controller
Microchip사에서 HSB Host Controller포함된 MCU가 나왔다. 저가격에 USB 호스트 지원하며 쓰기 쉬운 MCU가 되지 않을까..
기존 PIC24, dsPIC33과 전원및 ICSP핀이 동일해서 약간만 손보면 바로 적용할 수 있을것 같다.

16bit PIC MCU중에서 가장 저렴한 PIC24FJ16

16bit PIC MCU중에서 가장 저렴한 PIC24FJ16가 있는데 16k Flash, 4k RAM, 16MIPS에 1.6$로 상당히 매리트 있는 칩이다.
다음에 샘플주문 해서 소형, 저렴한 가격에 고성능을 원하는 어플리케이션에 적용하면 좋을것 같다.
전에 만들었던  dsPIC33-s EVM PCB에서 사용 가능하다.



레귤레이터가 내장되어 있어 dsPIC30과 달리 CORE전압을 내부에서 공급가능하다


참고로 전에 받아 두었던 dsPIC30스펙 이다.
