产品概述

The MCP402XEV is a MCP402X low cost evaluation board that quickly enables the user to exercise all of the features of the MCP402X non volatile digital potentiometer. This kit includes two PCBs, one populated & one unpopulated. The populated PCB has an MCP4021-103E/SN digital pot configured as a windowed potentiometer using a 2.5kR pull up and a 2.5kR pull down resistor. The PCB supports the 8 pin SOIC, SOT23-6 and SOT23-5 MCP402X package variations. A 6 pin PIC10F206-I/OT with flash memory is utilised to generate all of the low voltage and high voltage MCP402X serial commands when the two momentary switches are depressed in various sequences. This enables the user to increment and decrement the wiper, save the setting to EEPROM & exercise the WiperLocktm feature. The PCB also supports the standard ICSP programming header used by the BFMP low cost programming tool.

Non volatile memory(EEPROM)
Simple up/down protocol
Automatic recall of wiper setting on power up
Sample firmware to interface the PIC10F206 with push buttons & the MCP402X
Interprets momentary switch inputs to determine what serial command to execute
Uses a high speed oscillator output to create a low cost charge pump for HV commands
PCB supports in circuit serial programming using the BFMP programming header
One un populated PCB for rapid prototyping of an MCP402X application
Resistance values of 2kR, 5kR, 10kR and 50kR
