SPI（SerialPeripheralInterface---串行外设接口）总线系统是一种同步串行外设接口，允许MCU与各种外围设备以串行方式进行通信、数据交换，广泛应用于各种工业控制领域。
MAX187用采样／保持电路和逐位比较寄存器将输入的模拟信号转换为12位的数字信号，其采样／保持电路不需要外接电容。MAX187有2种操作模式：正常模式和休眠模式，将置为低电平进入休眠模式，这时的电流消耗降到10μA以下。置为高电平或悬空进入正常操作模式。 -AVR single-chip SPI serial ADC interface design SPI (SerialPeripheralInterface--- Serial Peripheral Interface) bus system is a synchronous serial peripheral interface that allows MCU with a variety of peripheral devices to the serial approach to communications , data exchange, widely used in various industrial control. MAX187 with sample/hold circuit and the case-by-bit compare register will be entered into the analog signal is converted to 12-bit digital signal, the sample/hold circuit does not require an external capacitor. MAX187 has two kinds of operating modes: normal mode and sleep mode, will be home to enter the sleep mode for low-level, when the current consumption down to 10μA. Or vacant home for high into the normal operating mode. Platform: |

Description: SoC是系统级集成，将构成一个系统的软/硬件集成在一个单一的IC芯片里，它一般包含片上总线、MPU核、SDRAM/DRAM、FLASH ROM、DSP、A/D、D/A、RTOS内核、网络协议栈、嵌入式实时应用程序等模块，同时，它也具有外部接口，如外部总线接口和I/O端口。通常，SoC中包含的一些模块是经过预先设计的系统宏单元部件（Macrocell）或核（Cores） ，或者例程（Routines），称为IP模块，这些模块都是可配置的，因此，基于SoC的设计方法学也称为基于IP的嵌入式系统设计方法学。
-SoC is a system-level integration, will constitute a system of hardware/software integrated in a single IC chip inside, which generally includes on-chip bus, MPU core, SDRAM/DRAM, FLASH ROM, DSP, A/D, D/A, RTOS kernel, network protocol stack, embedded real-time applications and other modules, the same time, it also has an external interface, such as external bus interface and I/O ports. Usually, SoC modules are included some of the pre-designed system macro-cell components (Macrocell) or nuclear (Cores), or routine (Routines), known as IP modules that are configurable, so, based on the SoC The design methodology is also known as IP-based embedded system design methodology.
