MSC1210中文资料--内核兼容8051的MSC1210单片机，具有高性能ADC、片内存储器以及Flash编程应用等功能。实际应用系统往往需要进行高精度的测量，同时还必须进行实时快速控制，提高其开发效率。为此人们常采用高精度A/D芯片加带ISP开发功能的单片机系统来实现。德州仪器（TI）的MSC1210单片机解决了上述问题。它集成了一个增强型8051内核、高达33 MHz的时钟周期、8路24位高精度∑-△A/D转换器、Flash存储器等-MSC1210 Chinese data- 8051 MSC1210 microcontroller core compatible with high-performance ADC, on-chip Flash program memory and application functions. Practical applications often require high-precision measurements, but also the need for real-time fast control, to improve their development efficiency. To do this people often use high-precision A/D chip increases with ISP microcontroller system development function to achieve. Texas Instruments (TI) of the MSC1210 microcontroller to solve the above problems. It integrates an enhanced 8051 core, up to 33 MHz clock cycle, 8-channel 24-bit high-precision Σ-△ A/D converter, Flash memory, and so on ... ...
