MCP4652-503E

Microchip Tech · Digital Potentiometers · MSOP-10

MCP4652-503E from Microchip Tech, in a MSOP-10. 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, which also acts as the High Voltage command pin when HVC/A0 = VIHH.
2 SCL input I2C serial clock input; the device is a slave that accepts only external clock signals.
3 SDA bidirectional I2C serial data I/O pin implemented as an open-drain N-channel driver.
4 VSS power_in Device ground reference.
5 P1B passive Potentiometer 1 terminal B, fixed connection to the zero-scale wiper value 0x00, with voltage limited between VSS and VDD.
6 P1W passive Potentiometer 1 wiper terminal, which may carry positive and negative current with voltage limited between VSS and VDD.
7 P0W passive Potentiometer 0 wiper terminal, which may carry positive and negative current with voltage limited between VSS and VDD.
8 P0B passive Potentiometer 0 terminal B, fixed connection to the zero-scale wiper value 0x00, with voltage limited between VSS and VDD.
9 A1 input I2C Address 1 pin which, together with A2 and A0, allows up to eight devices on one I2C bus.
10 VDD power_in Positive power supply input relative to VSS; electrical performance may not meet data sheet specifications while VDD is below 2.7V.
