TC520 串行接口适配器通常用于控制Telcom公司的TC500 / 500A系列双积分A/D转换器。这种适配器通过直接管理TC500转换器的相位控制信号A、B和CMPTR，减少了主处理器的工作负荷和软件复杂性。
TC520串行接口适配器具有一些关键特性，如可编程的转换速率和分辨率，提供了最大的灵活性，并支持高达17位的精度加上极性位。它还具有低功耗工作特性，通常功耗小于7.5MW，并提供了14引脚DIP封装或16引脚SOIC封装选项。
TC520 该适配器使用3线串行端口进行通信，并且转换后的数据（包括超量程和极性位）被保持在一个18位的移位寄存器中，直到被处理器读取或下一次转换完成。数据有效（DV）输出是一个有源驱动，在每个转换周期的开始时表示18位移位寄存器刚刚更新完成。这个信号可以被处理器轮询，或者用作数据就绪中断。
TC520串行接口适配器还需要一个5V逻辑电源，并且其时基可以从外部导出高达6MHz的频率源，或者可以从它自己的操作外部晶振导出。
The TC520 serial interface adapter is typically used to control Telcom's TC500/500A series of dual integrating A/D converters. This adapter reduces the workload and software complexity of the main processor by directly managing the phase control signals A, B, and CMPTR of the TC500 converter.
The TC520 serial interface adapter has some key features such as programmable conversion rate and resolution, provides maximum flexibility, and supports accuracy of up to 17 bits plus polar bits. It also features low-power operation, typically less than 7.5MW, and is available in either a 14-pin DIP package or a 16-pin SOIC package option.
TC520 The adapter uses a 3-wire serial port for communication, and the converted data (including overrange and polarity bits) is held in an 18-bit shift register until it is read by the processor or the next conversion is completed. The Data Effective (DV) output is an active driver that indicates at the beginning of each conversion cycle that the 18-bit shift register has just been updated. This signal can be polled by the processor or used as a data-ready interrupt.
The TC520 serial interface adapter also requires a 5V logic power supply, and its time base can be exported from an external frequency source up to 6MHz, or it can be exported from its own operating external crystal oscillator.
