单片机编程 Emulating a synchronous serial
The C500 microcontroller family usually provides only one on-chip synchronous serialchannel (SSC). If a second SSC is required, an emulation of the missing interface mayhelp to avoid an external hardware solution with additional electronic components.The solution presented in this paper and in the a ...
技术资料 FC162中文版说明书v21
FC162是一款低功耗，高速，高噪声容限，EPROM/ROM基于8位CMOS工艺制造的单片机，采用RISC指令集，共有42条指令，
除分支指令为两个周期指令以外其余为单周期指令。这种易用、易记的指令集大大缩短了开发时间。
FC162包含了上电复位(Power-on Reset POR)，掉电复位(Brown-out Reset BOR)， 上电复位计数器（Power-up Reset ...
模拟电子 电台维修模拟训练系统设计方法研究
Methods for designing a maintenance simulation training system for certain kind of radio are introduced. Fault modeling method is used to establish the fault database. The system sets up some typical failures， follow the prompts trainers can locate the fault source and confirm the type to accomplis ...
模拟电子 Active Filters
Power conversion by virtue of its basic role produces harmonics due to theslicing of either voltages or currents. To a large extent the pollution in theutility supply and the deterioration of the power quality has been generatedor created by non-linear converters. It is therefore ironic that power c ...
电源技术 DN460双输出降压稳压器优化效率
 
The LTC3546 is a dual output current mode buck regulatorwith fl exible output current partitioning. Beyondthe advantages normally associated with dual outputregulators (reduced size, cost, EMI and part count, withimproved effi ciency), the LTC3546’s outputs can bepartitioned for eit ...
