DATASHEET
Chapter 4 Product Description
The CAP1014 is a multiple channel Capacitive Touch sensor and LED Driver.
The CAP1014 contains up to 14 individual Capacitive Touch sensor inputs with programmable
sensitivity for use in touch button and slider switch applications. Each sensor also contains automatic
recalibration.
The CAP1014 also contains eleven (11) open drain LED drivers that offer full-on / off, variable rate
breathing, and dimness controls. Eight (8) of these LEDs can double as GPIOs and support open-drain
or push-pull operation.
Capacitive buttons can be linked to LED outputs. Additionally, LEDs 1-7
may be optionally linked to Buttons 1-7 so that when a touch is detected, the LED is actuated.
The device communicates with a host controller using SMBus. The host controller may poll the device
for updated information at any time or it may configure the device to flag an interrupt whenever a press
is detected on any sensor.
Each sensor is polled by the device approximately every 35 ms. The host may also initiate a
recalibratiion routine for one or more sensors or set up times and conditions so that the device
automatically invokes the re-calibration routine.
The CAP1014 contains multiple power states including several low power operating modes. In addition,
it contains a user driven RESET pin to force the device to reset.
A typical system diagram is shown in Figure 4.1.
