INTRODUCTION
WHAT IS THE MCP402X DIGITAL POTENTIOMETER EVALUATION BOARD?
This chapter provides an overview of the MCP402X Digital Potentiometer Evaluation
Board and covers the following topics:
• What is the MCP402X Digital Potentiometer Evaluation Board?
• What the MCP402X Digital Potentiometer Evaluation Board includes
The MCP402X Digital Potentiometer Evaluation Board (MCP402XEV) allows the
system designer to quickly evaluate the operation of Microchip Technology’s
MCP401X/2X Digital Potentiometer products.
The MCP402X Digital Potentiometer Evaluation Board PCB was designed to support:
• 8-pin, 150 mil SOIC MCP4021-XXX/SN devices
• SOT-23-6 MCP4022-XXX/OT devices
• SOT-23-6 MCP4023-XXX/OT devices
• SOT-23-5 MCP4024-XXX/OT devices
• 8-pin, 150 mil SOIC MCP4011-XXX/SN devices
• SOT-23-6 MCP4012-XXX/OT devices
• SOT-23-6 MCP4013-XXX/OT devices
• SOT-23-5 MCP4014-XXX/OT devices
In addition to supporting the MCP401X/2X, the MCP402XEV also utilizes the SOT-23-6
PIC10F20X microcontroller.
The PIC10F20X is supplied with example firmware that debounces the INCR and
DECR push buttons and generates the simple U/D protocol required by the
MCP401X/2X to increment and decrement the potentiometer’s wiper. It also generates
the simple U/D protocol required by the MCP402X to lock and unlock the
potentiometer’s wiper.
