multifunction timer chip

Dear All,

I am looking for an independent multifunction timer chip where I can interface it with PIC Microcontroller and take care care of all the timings. I google for some chips but the search direct me to china non-brands which I am not trusting. Did you used soemthing similar please just to have idea? the timer I need to build is similar to this but the pic will send the parameter to the timer.

Honestly just use the PIC.
Use one with an RTC, then you can sleep, wake once per second, and use
the alarms etc., to perform the functions.

Seems good suggestion...make an interrupt every second you means

Microchip has an 'application note' about how to code PICs for various types of timers. While in easy to use machine code, it's be simple to recode into CCS C.
There's no reason a PIC can't do what you want, though without 'specs' or 'parameters', I can't help any further.

I do have a HW RTC send a 1Hz interrupt for all my PIC projects with clocks. Has worked for decades. Most RTCs can be configured for faster interrupts if required.
