topic MC13211 VS MC13213 in 8-bit Microcontrollers https://community.nxp.com/t5/8-bit-Microcontrollers/MC13211-VS-MC13213/m-p/157969#M9237 <HTML><HEAD></HEAD><BODY><DIV> </DIV><P><SPAN style="font-family: Helv; font-size: 2;">I'm was using smac in MC13213 where the device goes to sleep mode (stop mode 3) and wakes up via a keyboard interrupt (PORTA/KBI), it worked fine. I changed the chip to MC13211 which has no difference except the RAM/ROM size.. The problem I faced after using the MC13211 chip is that I found there is a 600uA current draw in the sleep mode which is supposed to be less than 1uA!!! The same code on the same hardware draws 1uA if I use MC13213,, but when I use MC13211 the current start ramping from 50uA up to 600uA !! could anyone explain what is going.</SPAN></P><P><SPAN style="font-family: Helv; font-size: 2;">Regards</SPAN></P><DIV>Ehab</DIV></BODY></HTML> Wed, 24 Oct 2007 17:05:07 GMT e2saleh 2007-10-24T17:05:07Z MC13211 VS MC13213 https://community.nxp.com/t5/8-bit-Microcontrollers/MC13211-VS-MC13213/m-p/157969#M9237 <HTML><HEAD></HEAD><BODY><DIV> </DIV><P><SPAN style="font-family: Helv; font-size: 2;">I'm was using smac in MC13213 where the device goes to sleep mode (stop mode 3) and wakes up via a keyboard interrupt (PORTA/KBI), it worked fine.

Even it is inside the MCU (not pins outside).</DIV><DIV>Check every port declared to output or input with pullup enabled.</DIV><DIV>I faced the sam issue yesterday.</DIV><DIV>&nbsp;</DIV><DIV>Hope it helps.</DIV><DIV>&nbsp;</DIV><DIV>Regards,</DIV><DIV>Peter</DIV></BODY></HTML> Wed, 31 Oct 2007 16:15:08 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/MC13211-VS-MC13213/m-p/157970#M9238 FPatrick 2007-10-31T16:15:08Z
