摘要
ＳＰ５８Ｃ８０／ＭＳＰ５８Ｃ２０混合信号处理器，具有Ｓｉｇｍａ－Ｄｅｌｔａ编码解码器（ＣＯＤＥＣ），内置掩模式编程只读存储器，具有４８ｋｂｐｓ压缩率，在外部微控制器（ＭＣＵ）驱动下，可完成信息的存储、速览、删除、重播等功能。本文对ＭＳＰ５８Ｃ８０／ＭＳＰ５８Ｃ２０的工作原理、特点及外部接口，控制和应用等作了详细的讨论。
The MSP58C80 and its companion chipset MSP58c20 form a Mixed Signal Processor. The processor has an internal delta-sigma converter which provides analog to digital and digital to analog conversion. It can provide 48 kbps MCELP vocoder. Drived by an external host MCU , it can save, fast find, delete and replay messeges. In this paper the principal, features,external interface and application of MSP58C80 /MSP58c20 are described .
