ST92141 - ELECTRICAL CHARACTERISTICS

DC ELECTRICAL CHARACTERISTICS

(VDD = 5V ± 10%, TA = –40°C to +85°C, unless otherwise specified)

Note:

(1) Unless otherwise stated, typical data are based on TA=25°C and VDD=5V. They are only reported for design guidelines - not tested in pro-

duction.

(2) Data based on characterization results - not tested in production.

(3) For a description of the EMR1 Register - BSZ bit refer to the Device Configuration Registers Chapter.
