I2C I/O Pad Set

Overview

Key Features

• I2C Bi-directional Driver Features
• Supported I2C operating modes:
• Standard-mode (Sm) – 100 Kbps data rate
• Fast mode (Fm) – 400 Kbps data rate
• Fast mode (Fm+) – 1.0 Mbps data rate
• High-speed mode (Hs) - 3.4 Mbps data rate
• Open drain operation only
• Built-in output slew rate control to meet I2C Tof minimum of (20 x VDDP/5.5V) ns
• Output enable and mode select
• Receiver enable
• ESD protection is accomplished with an SCR (no diode to the positive power supply)
• Standard LVCMOS compatible input with optional Schmitt trigger (hysteresis)
• Power-on sequencing independent design with Power-On Control
• DVDD = 1.62V to 1.98V
• Pad VDDP = 1.62V to 1.98V – independent of DVDD
• The circuit consumes no DC supply current in the static state
• Fault-tolerant to 1.98V at PAD (no current flow when DVDD = 0V)
• An open-drain design, this cell requires an external pull-up resistor to a high voltage power supply. Designed for a 1.8V I2C bus application, VDDP can track DVDD but it is not necessary. The sizing of the external resistor or appropriate pull-up network is application dependent.
