Inter-integrated circuit interface (I
Up to two I
standard (up to 100 kHz), fast (up to 400 kHz) and fast mode + (up to 1 MHz) modes with
20 mA output drive. They support 7-bit and 10-bit addressing modes, multiple 7-bit slave
addresses (2 addresses, 1 with configurable mask). They also include programmable
analog and digital noise filters.
Table 6.
In addition, they provide hardware support for SMBUS 2.0 and PMBUS 1.1: ARP capability,
Host notify protocol, hardware CRC (PEC) generation/verification, timeout verifications and
ALERT protocol management. They also have a clock domain independent from the CPU
clock, allowing the application to wake up the MCU from Stop mode on address match.
