MPC755 Hardware Specications (order : Specications provided in this Part Number Specication supersede those in the MPC755EC/D) for these part numbers only specications not addressed herein are unchanged. Because this document is frequently updated, refer to the website at Freescale Semiconductor, Inc. 1.3 General Parameters The following general parameters apply to all part numbers described herein: Core power supply: 2.0 V 100 mV dc (nominal see Table 3 for recommended operating conditions) I/O power supply 1.8 V 100 mV dc (processor bus interface only not supported on L2 interface) or 2.0 V 100 mV dc (processor bus interface only not supported on L2 interface) or 3.3 V 165 mV dc (input thresholds are conguration pin selectable) Note that part revisions prior to Rev 2.8 (Rev E) do not support core voltages down to 1.8 V. 1.4.1 DC Electrical Characteristics All part numbers affected by this specication support 3.3V and 1.8V/2.0V I/O voltages but do not support 2.5V I/O voltages. Table 2 describes the input threshold voltage settings. These settings apply to all device revisions prior to Rev. 2.8 (Rev E), including all part numbers described herein. Note that the MPC745 does not provide an L2 interface.
