FT801 - Capacitive Touch Enabled Display, Audio and Touch Controller
IC |
|
|
The FT801 is a capacitive touch display controller which brings
together the functionality and system benefits of Embedded Video Engine
(EVE) technology together with the increased brightness, interactivity
and vividness associated with capacitive touchscreen technology in order
to create sophisticated and dynamic Human Machine Interfaces (HMIs).
This LCD controller is packaged in the same 48 pin QFN footprint as the FT800 and promotes architecture re-use for capacitive display needs, whilst providing the key elements seen in the FT800 including 3 in1 functionality (Display, Audio and Touch) and 1/16th pixel resolution, thus lowering BOM costs.

Designing with the FT801 |
|
| The FT801 can be easily interfaced to a capacitive touch controller via an I2C interface. The capacitive touch panel module (CTPM) asserts an interrupt when a touch is detected, signalling the FT801 to read the touch data via I2C. Additionally the FT801 supports a Compatibility touch mode, where existing FT800 application code can be run with single touch events detected, and Extended mode, which supports multi-touch sensing (up to 5 touchpoints) and gesturing.
