This group is for MPC5xx, not 55xx - please do not post questions regarding MPC55xx on this group. The preliminary electrical spec is out of date. The specification you are refering to has been updated to increase the range. You may run VDDEH at 3.3V and VDDA at 5.0V. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of peter_urban_toyota Sent: Friday, September 16, 2005 10:03 AM To: [email protected] Subject: [MPC500] HELP MPC5554MZP132 VDDEH =3V3 Possible? I have a preliminary electrical specification for the MPC5554 there is written: VDDEH can between 3V and 5.25V VDDA can between 4.5 and 5.5V In the chapter for the absolut maximum ratings is written VDDEH - VDDA must between -1V and 1V. If this is the case it is unpossible to run the VDDEH of MPC5554 with 3V3. Is my conclusion right? I like to run the VDDEH with 3.3V thsi makes my live easy. I need no level shifter. There is also written that the Absolut maximum ratings currently maximum burn in voltages and the the absolute maximum ratings are currently not determined.
