Description:
The MPR121 is the second generation capacitive touch sensor controller after the initial release of the MPR03x series devices. The MPR121 features increased internal intelligence, some of the major additions include an increased electrode count, a hardware configurable I2C address, an expanded filtering system with debounce, and completely independent electrodes with auto-configuration built in. The device also features a 13th simulated sensing channel dedicated for near proximity detection using the multiplexed sensing inputs.

Features:
1.71 V to 3.6 V supply operation
29 μA supply current at 16 ms sampling interval period
3 μA Stop mode current
12 capacitance sensing inputs 8 of inputs are multifunctional for LED driver and GPIO
Auto-configuration for each sensing input
Auto-calibration for each sensing input
Touch/release threshold and debounce for touch detection
I2C interface, with Interrupt output
-40°C to +85°C operating temperature range
