The I2C library provides the bidirectional I/O for two-line serial communication per Rev. 4 of the I2C-bus industry specification. The design is compatible with Standard-mode, Fast-mode, and High-speed mode I2C operating modes. This library is offered as a supplement to the IO libraries provided by Aragio Solutions
特色
- • 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
