MCP47DA1

SERIAL INTERFACE -
I2C MODULE
A 2-wire I2C serial protocol is used to write or read the
DAC’s wiper register. The I2C protocol utilizes the SCL
input pin and SDA input/output pin.
The I2C serial interface supports the following features:
Slave mode of operation
7-bit addressing
The following clock rate modes are supported:
- Standard mode, bit rates up to 100 kb/s
- Fast mode, bit rates up to 400 kb/s
Support Multi-Master Applications
The serial clock is generated by the Master.
The I2C Module is compatible with the NXP I2C
specification (UM10204). Only the field types, field
lengths, timings, etc. of a frame are defined. The frame
content defines the behavior of the device. The frame
content for the MCP47DA1 device is defined in this
section of the data sheet.

Typical Application I2C Bus
Configurations.
Refer to Section 2.0 “Typical Performance Curves”,
AC/DC Electrical Characteristics table for detailed input
threshold and timing specifications.
5.1
I2C I/O Considerations
I2C specifications require active low, passive high
functionality on devices interfacing to the bus. Since
devices may be operating on separate power supply
sources, ESD clamping diodes are not permitted. The
specification recommends using open drain transistors
tied to VSS (common) with a pull-up resistor. The
specification makes some general recommendations
on the size of this pull-up, but does not specify the
exact value since bus speeds and bus capacitance
impact
the
pull-up
value
for
optimum
system
performance.
Common pull-up values range from 1 k
to a maximum
of ~10 k
. Power sensitive applications tend to choose
higher values to minimize current losses during
communication but these applications also typically
utilize lower VDD.
The SDA and SCL float (are not driving) when the
device is powered down.
A "glitch" filter is on the SCL and SDA pins when the pin
is an input. When these pins are an output, there is a
slew rate control of the pin that is independent of device
frequency.
5.1.1
SLOPE CONTROL
The device implements slope control on the SDA
output. The slope control is defined by the fast mode
specifications.
For Fast (FS) mode, the device has spike suppression
and Schmitt trigger inputs on the SDA and SCL pins.
