Hi. Which is the most power-saving-mode for the C8051F310 uC? Until now i throttle the oscillator down to SYSCTL/8(~3MHz) and switch the CPU to IDLE-Mode. But the datasheet explains, that it already takes about 155 uA in IDLE-mode at 1MHz. Thats still too much for my application. I dont have space left for an external oscillator on my board, so switching to a lower frequency isn't possible. It shall go in sleep-mode and wait until an external interrupt occurs. Then it computes a little and goes to sleep again, until the next external interrupt occurs or the command of waking up arrives. It should not take more than 10-15uA in sleep-mode. Is this possible with this device? Many thanks in advance. Manuel
This is purely a hardware device-specific question: you need to speak to the manufacturer (Si Labs; nee Cygnal) about this. It is nothing to do with Keil Software tools - hence off-topic here! http://www.keil.com/forum/ Try the Si Labs forum instead.
Oh, i appologize for disregarding "http://www.keil.com/forum/" and posting [OT] in the wrong forum. I'll put my question in the silabs-forum. Thanks Manuel
A device-specific forum is generally the best place to get answers to a device-specifc question! ;-)
