Semtech Corporation SX8650

The SX8650 is an ultra low power 4-wire resistive touchscreen controller optimized for portable equipment where power and board-space are at a premium. It incorporates a highly accurate 12-bit ADC for data conversion and operates from a single 1.65 to 3.7V supply voltage. The SX8650 features a built-in preprocessing algorithm for data measurements, which greatly reduces the host processing overhead and bus activity.

GENERAL DESCRIPTION

KEY PRODUCT

FEATURES

This complete touchscreen solution includes four user-selectable operation modes which offer programmability on different configurations such as conversion rate and settling time, thus enable optimization in throughput and power consumption for a wide range of touch sensing applications. The touch screen inputs have been specially designed to provide robust on-chip ESD protection of up to ±15kV in both HBM and Contact Discharge, and eliminates the need for external protection devices. The SX8650 supports the Fast-mode I²C (400kbit/s) serial bus data protocol and includes 2 user-selectable slave addresses. A custom I2C address is possible on request. The SX8650 is offered in two tiny packages: 3.0 mm x 3.0 mm DFN and a 1.5 mm x 2.0 mm wafer-level chip-scale package (WLCSP).
