• Wake up from total power down mode
    I use the MCB900 prototype board (revision E). My source code is in assembler (.a51) When I debbug my code with µvision2 software, I have No errors, No Warning, and all the interrupts are abble to...
  • Wake up from power-down only once
    Hello all, I am working on a project using Winbond W77E58. To save energy, if there is no trigger input from P3.2 (INT0/), P3.3 (INT1/) or P3.0 (Serial Port) for some time the MCU will go into power...
  • Power down mode
    I'm using CC1010 in a project and it's datasheet says that the consumption in power down mode is 0,2 uA. My circuit is consuming 38,8 uA with only the CC1010 on it, I took off the periphericals. It's...
  • 89S52 Power Down Mode.
    89S52 External Interrupts. Hi all... i am making a project for driving a dc motor clock and anticlock wise using L293D which is connected to port 3^3(pin 2 of L293D) and port3^4(Pin 7 of L293D) and...
  • Power Down Mode Application
    I am using LPC2138 and I'd like to set it into power down mode to conserve power. Based on the data sheet, LPC2138 is able to wake up by RTC (Interrupt Wakeup Register - INTWAKE, bit 15) What i have...
