MCU, comms module and voltage regulation sections. No system this complex has shown up on this site. Is the enable line capable of effectively “resetting” the latches? As has been said, you can make this function from more 74HCT-etc gates.

I had a sync.

Any suggestion on how to implement this otherwise? Basically the MCU would read these lines at regular intervals minutes?

I would disagree, but I may be missing the picture here. The most complex part by design is planned to be the MCU. Home Questions Tags Datasheeh Unanswered. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Sign up using Email and Password. I am working on a circuit where I need to hold a few signals until my MCU reads them.

I have toyed briefly with the possibility to use the Enable line, but was not sure if it would have cleared the latched states. You may be looking for this: Backup question maybe deserving its own question: While this is not a huge problem to solve and still match my requirements, the resulting design is not as clear as it would be with a single Reset and the density is lower, requiring me to use more ICs.

You will then need pull-ups on every output instead of pull-downs, so just use the pull-ups of the MCU inputs by configuring it accordingly.

You can derive a similar deduction for CD You can achieve the same externally in your PCB design, very easily albeit with a lower density, you’re right.

OTOH, you might way to use the common enable in the CD to implement the solution you’re looking for.

Why does this work? To conserve bandwidth, I only needed 1 bit in a synchronous “sub-frame” channel to send the analog signal as a digital FM signal of 0 to 1kHz. I would spare the fixed via to the enable having it routed to the MCU and used to control the reset AND the enable itself and would have all the resets linked together in a clean way. However is practically impossible to find good supply of datashset and even a datasheet.

While catasheet the ideal for the approach here simple, cheap and reliable circuit, with only the MCU as “critical complexity”I believe that your comment dataasheet deserve an answer by itself for posterity. SNN simply has all of its reset inputs internally connected. Is there a reason why you have to use the fewest ICs?

Following up my previous comment: I think you need to re-evaluate how much power is required by “keeping the interrupts alive”. Sign up using Facebook. The way I plan to implement it the MCU could well stay sleeping all the day, until the measurements are taken and the SR reset. Sign up or log in Sign up using Google. Enric Blanco 4, 5 11 Sourcing it could be really troublesome.

Comments like these are one of the many reasons for which I regret skipping all the theory in the electronic classes and being in the first line only when there was the risk to toast stuff.

I want to keep it flexible, both capability and power-usage wise and this requires balance. You might way to use the common enable in the CD to implement the solution you’re looking for.
