+title: STMicroelectonics Port Expander (STMPE) GPIO Block
+
+description:
+ STMicroelectronics Port Expander (STMPE) is a series of slow
+ bus controllers for various expanded peripherals such as GPIO, keypad,
+ touchscreen, ADC, PWM or rotator. It can contain one or several different
+ peripherals connected to SPI or I2C. These bindings pertain to the
+ GPIO portions of these expanders.
