Key Features
- 5 kΩ non-volatile digital potentiometer with 64-step resolution retaining wiper position through power cycles via internal EEPROM
- Increment/decrement 2-wire control interface requiring minimal GPIO pins for simple wiper adjustment
- 2 kHz bandwidth in a compact MSOP-8 package for audio, gain-trim, and bias-setting applications
Applications
The MCP4021-502E/MS is used in one-time or infrequent calibration circuits where the wiper position must be preserved after power-off, such as sensor offset trimming, amplifier gain adjustment, and LCD contrast control. Its 5 kΩ resistance with 64 steps provides fine trimming resolution for precision analog circuits in industrial instruments and consumer appliances. The simple up/down control interface integrates easily with any microcontroller GPIO without requiring a full SPI or I2C peripheral.

Frequently Asked Questions
How does MCP4021-502E/MS retain its setting after power is removed?
The device stores the current 64-step wiper position in internal non-volatile EEPROM, so the last programmed resistance between 0 Ω and 5 kΩ is automatically restored on every power-up without requiring MCU re-initialization.
What control interface does MCP4021-502E/MS use, and how many GPIO pins does it need?
The MCP4021-502E/MS uses a simple 2-pin increment/decrement interface that requires only 2 GPIO outputs from the host microcontroller, making it ideal for designs where SPI or I2C bus resources are not available.
Is MCP4021-502E/MS suitable for audio volume control at line-level frequencies?
Yes. The 2 kHz bandwidth covers audio line-level control applications up to the midrange, and the 5 kΩ end-to-end resistance with 64 steps provides roughly 78 Ω per step for smooth volume increments in portable speaker or headphone amplifier designs.
