MCP4532T-104E

Microchip Tech · Digital Potentiometers · MSOP-8

MCP4532T-104E 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 High-voltage tolerant (up to 12.5V) Schmitt-trigger input serving as I2C Address 0 (latched at POR/BOR) and as the High Voltage command pin when driven to VIHH.
2 SCL input I2C serial clock input from the host; the device is a slave and accepts only external clock signals (high-voltage tolerant, Schmitt trigger).
3 SDA bidirectional I2C serial data I/O with an open-drain N-channel output driver (high-voltage tolerant, Schmitt trigger).
4 VSS power_in Ground reference for the device.
5 P0W passive Potentiometer 0 wiper terminal (rheostat wiper); supports positive and negative current and its voltage must be between VSS and VDD.
6 P0B passive Potentiometer 0 terminal B, the fixed zero-scale connection (wiper value 0x00); supports positive and negative current and its voltage must be between VSS and VDD.
7 A1 input I2C Address 1 input (high-voltage tolerant, Schmitt trigger) which, with A2 and A0, allows up to eight devices on one I2C bus.
8 VDD power_in Positive power supply input relative to VSS; device operation 1.8V to 5.5V, characteristics specified 2.7V to 5.5V.
