FUNCTIONAL OVERVIEW
This Data Sheet covers a family of thirty-two Digital
Potentiometer and Rheostat devices that will be
referred to as MCP4XXX. The MCP4XX1 devices are
the Potentiometer configuration, while the MCP4XX2
devices are the Rheostat configuration.
As the Device Block Diagram shows, there are four
main functional blocks. These are:
The POR/BOR operation and the Memory Map are
discussed in this section and the Resistor Network and
SPI operation are described in their own sections. The
commands are discussed in
4.1
POR/BOR Operation
The Power-on Reset is the case where the device is
having power applied to it from VSS. The Brown-out
Reset occurs when a device had power applied to it,
and that power (voltage) drops below the specified
range.
The devices RAM retention voltage (VRAM) is lower
than the POR/BOR voltage trip point (VPOR/VBOR). The
maximum VPOR/VBOR voltage is less then 1.8V.
When VPOR/VBOR < VDD < 2.7V, the electrical
performance
may
not
meet
the
data
sheet
specifications. In this region, the device is capable of
reading and writing to its EEPROM and incrementing,
decrementing, reading and writing to its volatile
memory if the proper serial command is executed.
4.1.1
POWER-ON RESET
When the device powers up, the device VDD will cross
the VPOR/VBOR voltage. Once the VDD voltage crosses
the VPOR/VBOR voltage the following happens:
Volatile wiper register is loaded with value in the
corresponding non-volatile wiper register
The TCON register is loaded it’s default value
The device is capable of digital operation
4.1.2
BROWN-OUT RESET
When the device powers down, the device VDD will
cross the VPOR/VBOR voltage.
Once the VDD voltage decreases below the VPOR/VBOR
voltage the following happens:
Serial Interface is disabled
EEPROM Writes are disabled
If the VDD voltage decreases below the VRAM voltage
the following happens:
Volatile wiper registers may become corrupted
TCON register may become corrupted
As the voltage recovers above the VPOR/VBOR voltage
Serial commands not completed due to a brown-out
condition may cause the memory location (volatile and
non-volatile) to become corrupted.
4.2
Memory Map
The device memory is 16 locations that are 9-bits wide
(16x9 bits). This memory space contains both volatile
and non-volatile locations (see Table 4-1).
