I2C IO Pad Set

Overview

Key Features

• • Supported I2C operating modes:
• o Standard-mode (Sm) – 100 Kbps data rate
• o Fast mode (Fm) – 400 Kbps data rate
• o Fast mode (Fm+) – 1.0 Mbps data rate
• • Open drain operation only (floating NWELL with PMOS used for ESD protection only)
• • Built-in output slew rate control to meet I2C Tof minimum of (20 x VDDP/5.5V) ns
• • Output enable
• • Receiver enable
• • ESD protection uses snap-back devices (no diode to the positive power supply)
• • Standard LVCMOS input thresholds (no hysteresis)
• • Staggered I/O CUP implementation
• • Power-on sequencing independent design with Power-On Control
• • DVDD = 2.7V to 3.63V and VDD = 0.85V to 1.1V
• • Pad VDDP (power supply reference for Output) = 2.7V to 3.63V independent of DVDD.
• • The circuit consumes no DC supply current in the static state
