Electrical characteristics

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

characteristics, and AC timing specifications for the SPC564A80 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 8 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.

Table 8.

Parameter classifications

Classification tag

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.
