LN91SAM7S

LN91SAM7S

General Description
ARM7TDMI 코어 기반의 제어 모듈로, 하나의 칩에 플래시 메모리와 SRAM을 내장하고 있어 마이컴과 같은 형태의 구현이 가능하다. 사용은 마이컴과 같이 심플하고 가격도 비슷한 저가격 수준이지만, 486 급의 고성능이며 풍부한 주변장치와 메모리를 기반으로 다양한 임베디드 제어장치를 개발할 수 있다. 내장된 ADC 및 주변 장치를 통해 센서나 모터를 제어할 수 있으며, 고성능 연산 능력으로 FFT 처리나 FIR/IIR 디지털 필터와 같은 연산처리도 실시간으로 처리할 수 있다.
