Electrical characteristics

3.1

Introduction

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

characteristics, and AC timing specifications.

In the tables where the device logic provides signals with their respective timing

characteristics, the symbol “CC” (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” (System Requirement) is included in the

“Symbol” column.

Note:

Parameters given to junction temperature TJ = 150 °C are for packaged parts .

Note:

Within this document, VDD_HV_IO refers to supply pins VDD_HV_IO_MAIN, VDD_HV_IO_JTAG,

VDD_HV_IO_FLEX, and VDD_HV_FLA.

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 6 are used and

the parameters are tagged accordingly in the tables where appropriate.

Absolute maximum ratings

Table 7 describes the maximum ratings of the device.

Table 6. Parameter classifications

Classification tag

Tag description

Parameters are guaranteed by production testing on each individual device.

Parameters are guaranteed by the design characterization by measuring a statistically relevant

sample size across process variations.

Parameters are guaranteed 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.

Parameters are derived mainly from simulations.
