Low-power touch controller offers unmatched noise immunity and tracking accuracy

Targeted the rapidly growing tablet and ultrabook market, the CY8CTMA1036 Gen 4 TrueTouch controller is clamed to deliver unmatched noise immunity and tracking accuracy with the lowest-available power for touchscreens up to 12 in. — offering an active power consumption of 2 mW, and a deep sleep mode that draws only 1.8 µW with wake-up via address match on the COM port. The part uses a 32-bit ARM Cortex core, and offers 65 sensing I/O channels with support for up to 1,036 nodes on the screen, 35% more than any other single-chip solution.

The CY8CTMA1036 is said to be the first and only touchscreen IC that delivers built-in 10-V Tx to drive the touch panel at 10 V. Because SNR is directly proportional to the voltage at which the panel is driven, this feature allows Cypress to offer nearly four times the SNR of the next closest competitor. The Gen4 product family also boasts the industry’s fastest refresh rate of 400Hz, and has the unique ability to scan a capacitive touch panel at 1,000 Hz – both industry-best metrics.

Other features include waterproofing functionality that allows products to meet IP-67 standards; 1-mm stylus support for Asian character sets and accurate handwriting capture; and hover sensing to provide mouseover-like features and true fingernail or thick-glove support in mobile devices. It also offers the ability to switch dynamically between self-capacitive and mutual-capacitive sensing methods in application enables these differentiating features.(Contact company for pricing — available now.)
