Electrical characteristics

This section contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing

specifications for the MPC5642A 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 supplement are guaranteed by various methods. To give the customer a better

understanding, the classifications listed in Table 7 are used and the parameters are tagged accordingly in the tables where

appropriate.

NOTE

The classification is shown in the column labeled “C” in the parameter tables where

appropriate.

Tag description

Those parameters are guaranteed during production testing on each individual device.

Those parameters are achieved by the design characterization by measuring a statistically

relevant sample size across process variations.

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.

Those parameters are derived mainly from simulations.
