ADVANCED COMMUNICATIONS & SENSING

The SX8660 is an ultra low power, fully integrated 8-

channel

applications. Unlike many capacitive touch solutions,

the SX8660 features dedicated capacitive sense

inputs (that requires no external components) in

addition to 8 general purpose I/O ports (GPIO). Each

of the 8 on-chip GPIO/LED driver is equipped with

independent PWM source for enhanced visual effect

such as dimming, blinking and breathing.

The SX8660 includes a capacitive 10 bit ADC analog

interface with automatic compensation up to 100pF.

The high resolution capacitive sensing supports a

wide variety of touch pad sizes and shapes and

allows capacitive buttons to be created using thick

overlay materials (up to 5mm) for an extremely

robust and ESD immune system design.

The SX8660 incorporates a versatile firmware that

was specially designed to simplify capacitive touch

solution design and offers reduced time-to-market.

Integrated

provides the ultimate flexibility to modify key firmware

parameters (gain, threshold, scan period, auto offset

compensation) in the field without the need for new

firmware development.

The SX8660 supports the 400 kHz I²C serial bus

data protocol and includes a field programmable

slave address. The tiny 4mm x 4mm footprint makes

it an ideal solution for portable, battery powered

applications where power and density are at a

premium.
