Electrical characteristics
This section contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing
specifications for the MPC5634M series of MCUs.
The electrical specifications are preliminary and are from previous designs, design simulations, or initial evaluation. These
specifications may not be fully tested or guaranteed at this early stage of the product life cycle, however for production silicon
these specifications will be met. Finalized specifications will be published after complete characterization and device
qualifications have been completed.
In the tables where the device logic provides signals with their respective timing characteristics, the symbol “CC” for Controller
Characteristics is included in the Symbol column.
In the tables where the external system must provide signals with their respective timing characteristics to the device, the symbol
“SR” for System Requirement is included in the Symbol column.

Parameter classification
The electrical parameters shown in this document are guaranteed by various methods. To provide a better understanding, the
classifications listed in
Table 7 are used and the parameters are tagged accordingly in the tables. Note that only controller
characteristics (“CC”) are classified. System requirements (“SR”) are operating conditions that must be provided to ensure
normal device operation.
NOTE
The classification is shown in the column labeled “C” in the parameter tables where
appropriate.

Tag description
P
Those parameters are guaranteed during production testing on each individual device.
C
Those parameters are achieved by the design characterization by measuring a statistically
relevant sample size across process variations.
T
Those parameters are achieved by design characterization on a small sample size from typical
devices under typical conditions unless otherwise noted. All values shown in the typical column
are within this category.
D
Those parameters are derived mainly from simulations.
