What uses pin Vss5 in LPC2114
2006-01-02 by mc maddie
I had/have problems with current consumption in design that uses LPC2114. 3V3 current consumption is steadily about 1mA and I have tried to find the cause for that. Today I was connecting the last Vcc pin when I had off-by-one - error and instead Vcc pin I disconnected Vss5(pin 50). When I noticed my error I tried to reconnect Vss5, but it fall off so I couldn't reconnect it. Despite of that I switched power on for the system and now current consumption was only about 100uA! Device was working in some level because uart worked ok. I haven't tested everything because obviously something is not working. I would just wanna know what peripherals etc. uses Vss5 so I could start looking for cause my 'huge' current consumption.
