Hello everyone. I want to create a 8051 development board which can use ic p89v51rd2.So can any one give me the full ckt diagram and components list that should be connected to ic for safe operation and avoiding pin burnout due to excess current flow?Also for using at89c51rd2 microcontroller?
what is sn74hct573n? and can it be used with microcontroller to prevent pin burnout due to current flow?
its upto you what an all you want to give in you development board… for some option you can LED, segment, ADC, relay, LED array, etc… i dont understand your burnout condition part… for more sefty precautions you can use 7805 voltage regulator ic…
the basic circuitry for giving power supply to the mocrocontroller and transfering data from pc to microcontroller?
for communication b/w PC and controller which periperial you will be using… is it RS232 or USB… if you using RS232 use max232 in b/w that will take care for voltlage and the current part and if you using USB the in/p must be 3.6v and the current must not exceed then 500mA… the o/p from PC is defined by the device itself when it get enumarated… if you using Parallel one you and use a buffer like ULN or 74hct541….
