产品模型 3

特性

400MHz/800MMAC的性能可实现多媒体应用中的多通道音频和CIF视频处理
具备片上内核电压调节功能的增强型动态电源管理可实现0.8V的工作电压，从而延长便携应用中的电池使用寿命

针对数据采集应用而优化的外设，提供与通用转换器的无缝连接
低成本且引脚和代码兼容的系列衍生产品，使得在成本敏感的消费类应用中的软件差异化成为可能

更多细节

ADI公司早期的ADSP-BF531、ADSP-BF532和ADSP-BF533产品系列具备Blackfin处理器的所有简单易用和架构上的特性。这三个处理器全部完全引脚兼容，仅在其性能和片上存储器方面有所不同，从而降低了风险，并提供根据终端应用要求进行灵活扩展的能力。所有这三个处理器都具备低功耗以及从低成本到极高性能的可扩展性能。

ADSP-BF531是Blackfin处理器系列的低成本切入点。它实现了性能、外设集成和价格之间的完美平衡，非常合适用于便携式测试设备、嵌入式调制解调器、生物特征识别和消费类音频等大多数对成本敏感的应用。
