STR71xF - INTRODUCTION

11/49

Legend / Abbreviations for Table 3:

Type:

I = input, O = output, S = supply, HiZ= high impedance,

In/Output level: C = CMOS 0.3VDD/0.7VDD

CT= CMOS 0.8V / 2V with input trigger

TT= TTL 0.3VDD/0.7VDD with input trigger

C/T = Programmable levels: CMOS 0.3VDD/0.7VDD or TTL 0.8V / 2V

Port and control configuration:

– Input:

pu/pd= software enabled internal pull-up or pull down

pu= in reset state, the internal 100k

Ω weak pull-up is enabled.

pd = in reset state, the internal 100k

Ω weak pull-down is enabled.

– Output:

OD = open drain (logic level)

PP = push-pull

T = true OD, (P-Buffer and protection diode to VDD not implemented), 5V tolerant.
