MCP4531T-502E

Microchip Tech · Digital Potentiometers · MSOP-8

MCP4531T-502E from Microchip Tech, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 HVC/A0 input Address 0 input for the I2C interface, latched at POR/BOR, and also the high-voltage command pin (normal command vs. high-voltage command when driven to VIHH); digital inputs are high-voltage tolerant up to 12.5V with Schmitt-trigger input.
2 SCL input I2C serial clock input that accepts only external clock signals from the host controller; the input is high-voltage tolerant with Schmitt trigger.
3 SDA bidirectional I2C serial data I/O implemented as an open-drain N-channel driver.
4 VSS power_in Device ground reference.
5 P0A passive Potentiometer 0 Terminal A, fixed connection to the full-scale wiper value (0x80 for 7-bit devices); the voltage must be between VSS and VDD and it can carry positive or negative current.
6 P0W passive Potentiometer 0 wiper terminal, the adjustable terminal of the digital potentiometer; the voltage must be between VSS and VDD and it can carry positive or negative current.
7 P0B passive Potentiometer 0 Terminal B, fixed connection to the zero-scale wiper value (0x00); the voltage must be between VSS and VDD and it can carry positive or negative current.
8 VDD power_in Positive power supply input referenced to VSS; electrical performance may not meet data sheet specifications while VDD is below 2.7V.
