General Description

The CAP1296 is a multiple channel capacitive touch

sensor controller. It contains six (6) individual capaci-

tive touch sensor inputs with programmable sensitivity

for use in touch sensor applications. Each sensor input

is calibrated to compensate for system parasitic capac-

itance and automatically recalibrated to compensate

for gradual environmental changes.

In addition, the CAP1296 can be configured to detect

proximity on one or more channels with an optional sig-

nal guard to reduce noise sensitivity and to isolate the

proximity antenna from nearby conductive surfaces

that would otherwise attenuate the e-field.

The CAP1296 includes Multiple Pattern Touch recogni-

tion that allows the user to select a specific set of but-

tons to be touched simultaneously. If this pattern is

detected, a status bit is set and an interrupt is gener-

ated.

The CAP1296 has Active and Standby states, each

with its own sensor input configuration controls. The

Combo state allows a combination of sensor input con-

trols to be used which enables one or more sensor

inputs to operate as buttons while another sensor input

is operating as a proximity detector. Power consump-

tion in the Standby and Combo states is dependent on

the number of sensor inputs enabled as well as averag-

ing, sampling time, and cycle time. Deep Sleep is the

lowest power state available, drawing 5µA (typical) of

current. In this state, no sensor inputs are active, and

communications will wake the device.

TO OUR VALUED CUSTOMERS

It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip

products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be rened and

enhanced as new volumes and updates are introduced.

If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via

E-mail at docerrors@microchip.com. We welcome your feedback.

Most Current Data Sheet

To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:

http://www.microchip.com

You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.

The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).

Errata

An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for cur-

rent devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the

revision of silicon and revision of document to which it applies.

To determine if an errata sheet exists for a particular device, please check with one of the following:

• Microchip’s Worldwide Web site; http://www.microchip.com

• Your local Microchip sales office (see last page)

When contacting a sales office, please specify which device, revision of silicon and data sheet (include -literature number) you are

using.
