ST92F124/F150/F250 - ELECTRICAL CHARACTERISTICS

Note:

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

production.

(2) Value guaranteed by characterisation.

(3) For a description of the EMR1 Register - BSZ bit refer to the External Memory Interface Chapter.

(4) Value guaranteed by Design.

(5) Not tested in production, guaranteed by product characterisation. An overload condition occurs when the input voltage on any pin ex-

ceeds the specified voltage range.

(6) Indicative values extracted from design simulation, 20% to 80% on 50pF load, EMR1.BSZ bit =0.
