The MCP402X Digital Potentiomenter Evalua-
tion Board kit (MCP402XEV) contains a simple
demonstration board utilizing a PIC10F206, the
MCP4021 and a blank PCB, which can be
populated with any desired MCP4021/2/3/4
device in a SOT-23-5, SOT-23-6 or 150 mil
SOIC 8-pin package.
This board has two push buttons to control when
the PIC
serial commands. The example firmware dem-
onstrates the following commands:
• Increment
• Decrement
• High-Voltage Increment and Enable
• High-Voltage Decrement and Enable
• High-Voltage Increment and Disable
• High-Voltage Decrement and Disable
The populated board (with the MCP4021) can
be used to evaluate the other MCP402X devices
by appropriately jumpering the PCB pads.
The SOT-23-5/6 Evaluation Board (VSUPEV2)
can be used to evaluate the characteristics of
the
devices.
The 8-pin SOIC/MSOP/TSSOP/DIP Evaluation
Board (SOIC8EV) can be used to evaluate the
characteristics of the MCP4021 device in either
the SOIC or MSOP package.
The MCP4XXX Digital Potentiometer Daughter
Board allows the system designer to quickly
evaluate the operation of Microchip Technol-
ogy's MCP42XXX and MCP402X Digital Poten-
tiometers. The board supports two MCP42XXX
devices and an MCP402X device, which can be
replaced with an MCP401X device.
The board also has a voltage doubler device
(TC1240A), which can be used to show the
WiperLock™
MCP4021.
