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
