the a121x family, produced with bicmos technology, consists of devices that feature fast power-on time and low-noise operation.
该A121x系列,采用BiCMOS技术生产,包括设备,具有快速通电时间和低噪音运行。
At first, we point out that in the embedded system the power-on reset ( POR) circuit of CPU and EPLD should not only satisfied the request of reset time but also offer correct time sequence to make POR step finished when initializing EPLD.
首先介绍了在嵌入式系统中,CPU和可编程芯片上电复位电路不仅要满足复位时间要求,而且还要有正确的时序,保证在对可编程芯片初始化时,该芯片上电复位已经结束。
