Overview
The LC717A10PJ is a high-performance and low-cost capacitance-digital-converter LSI for electrostatic
capacitive touch sensor, especially focused on usability.
It has 16 channels capacitance-sensor input. This makes it ideal for use in the products that need many switches.
Since the calibration function and the judgment of ON/OFF are automatically performed in LSI internal, it can
make development time more short. A detection result (ON/OFF) for each input can be read out by the serial
interface (I²C compatible bus or SPI).
Also, measurement value of each input can be read out as 8-bit digital data. Moreover, gain and other parameters
can be adjusted using serial interface.
Function
 Detection system: Differential capacitance detection (Mutual capacitance type)
 Input capacitance resolution: Can detect capacitance changes in the femto Farad order
 Measurement interval (16 differential inputs): 30ms (Typ) (at initial configuration),
6ms (Typ) (at minimum interval configuration)
 External components for measurement: Not required
 Interface: I²C * compatible bus or SPI selectable.
 Current consumption: 570A (Typ) (VDD = 2.8V), 1.3mA (Typ) (VDD = 5.5V)
 Supply voltage: 2.6V to 5.5V
 Detection operations: Switch
 Packages: SSOP30
