CREF, Current Bias Resistor
To insure proper operation of the AMIS-52000, this can only
be a precision resistor with a value of 33.2KΩ. Use a 1% or
better resistor tolerance.
I²CDATA, I²CCLK, Control Interface 2-wire Bus
The AMIS-52000 implements an I²C serial 8 bit bi-directional
interface with the pins I²CDATA and I²CCLK. The I²C bus

handshaking and protocol is implemented for a SLAVE
device. The interface can connect directly to a host or
controller I²C interface. There are internal pullup resistors
on both the I²CDATA and I²CCLK lines of the AMIS-52000.
The interface can handle data rates as defined in the I²C
specification up to 400Kbps.
