Description

This article describes the features and specifications of the CY8CTMA340-49LQI-01 electronic component model, which belongs to the IC Chips product category. This product is a multi-touch capacitive touchscreen and touchpad controller, designed for use in automotive electronics and other applications.

Specifications and Features

The CY8CTMA340-49LQI-01 is a 32-bit ARM Cortex CPU with register configurable features. It has noise suppression technologies for display and EMI, and an on-chip 10-V TX supply for higher signal-to-noise ratio (SNR). Additionally, this product has external display synchronization, water rejection and wet finger tracking, large object rejection, automatic baseline tracking to environmental changes, and a low-power look-for-touch mode.

The system performance of CY8CTMA340-49LQI-01 allows screen sizes up to 10.1-inch diagonal, reports up to 10 fingers, and small/large finger support down to 5 mm and up to 22 mm, respectively. This product features a refresh rate up to 80 Hz and fast first-touch response (≤ 37.5 ms for a 10.1-inch panel).

The CY8CTMA340-49LQI-01 requires a 1.71-V to 5.5-V digital and I/O supply, and 2.60-V to 5.5-V analog supply. The average power consumption while sensing is 71 mW, and deep-sleep power requires only 45 μW. I2C and SPI interface options are available.

Application Scenarios

This product is specifically designed for use in automotive electronics, but it can be used in other applications wherever a multi-touch capacitive touchscreen and touchpad controller is required. It supports a variety of touchscreen sensors and stackups, and different temperature ranges.
