PSoC™ 5, 3 & 1 Forum Discussions

I'm doing some research that requires a lot of comparators. Currently, for proof of concept, I'm using LM319's because their open collector outputs allow me to use any output voltage I want if the comparator is "high" and they allow me to tie their "ground" to different voltages as long as it is higher than Vsss so the output when the comparator is "low" is also configurable.

The problem is that I need a heck of a lot of them and I'm looking for configurable solutions. So far the Cypress PSoC 3 looks like a candidate but I need to know more about them (maybe the 4 or 5 would be better, or some other product entirely). First, how many comparators can you get from one of the configurable analog blocks? I couldn't find much detail on the internals of the analog blocks. Second, how flexible are the comparators themselves? From reading the datasheet for the COMP module, it looks like high=Vdd and low=Vss. Is there any way to manipulate this so that the lows and highs are equal to some other intermediate voltage references?

Thanks much for any help!

Hi.

I would like to implement a RTC that doesn`t lose the time data after a power failure. I am thinking to use a 5V battery. How do I have to do the connections? Do I have to use de Boost? Which elements do I need?

Thanks

Bueno actualización el creador PSoC 2.2, hará un acelerómetro práctico, pero cuando voy a poner el control pasadores no me deja porque son pines de un vidrio, estoy trabajando con PSoC 5 antes de actualizar el software de los pines del acelerómetro Ellos eran 15,0-15,2 alguien me podría decir en lo que son PSoC 2.2
 

Hi,

I want to multiply two signals using a mixer. But i want to give clock a sign signal. I tried to do that but it shows an error signal attached with this message.

Please guide me how i can do this.

Looking forward for your reply

Best Regards
