Today’s computer, datacom, and telecom systems demandpower supplies that are effi cient, respond quicklyto load transients and accurately regulate the voltageat the load. For example, load current can be measuredby using the inductor DCR, thus eliminating the needfor a dedicated sen ...
CAT5110/18/19/23/24/25 linear-taper digitally programmable potentiometers perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a2-wire up/down serial inte ...
The STWD100 watchdog timer circuits are self-contained devices which prevent systemfailures that are caused by certain types of hardware errors (non-responding peripherals,bus contention, etc.) or software errors (bad code jump, code stuck in loop, etc.).The STWD100 watchdog timer has an input, WDI, ...
When the P89LPC90x is in programming mode all pins that are not used for programming are tri-stated. During
programming mode the reset pin has a weak pull-up resistor.
富士通单片机MB902420系列The internal LCD-cotroller will be initialised (1/2 bias, 1/2 duty).
The internal Resistor devider is used.
Some different methods are shown, how segments can be swicthed on/off.
Description: This program demonstrates a half-duplex 9600-baud UART using
// Timer_A3 using no XTAL and an external resistor for DCO ROSC. DCO used for
// TACLK UART baud generation. The program will wait in LPM4, echoing back
// a received character using 8N1 protocol. On valid RX character, the
// ...
I often need a simple function generator. Just to generate a certain frequency. After all the years I ve worked with electronics, I still haven t got me one. Even though I need it now and then, I just couldn t seem to justify the cost of one.
So, standard solution - build one yourself.
I designed a ...
