Cypress Launches Single-Chip TrueTouch® Controller Based on Gen4 Technology for Tablets, Ultrabooks and Laptops
January 10 2012 - 9:00AM
Business Wire
Cypress Semiconductor Corp. (NASDAQ: CY) today introduced a new
Gen4 TrueTouch® controller targeted at the rapidly growing tablet
and ultrabook market. The new CY8CTMA1036 device has 65 sense-I/Os,
enabling it to deliver flawless touchscreen performance for screens
up to 12 inches. Like the smaller-screen Gen4 devices, it offers
industry-best performance in all categories, including the world’s
best signal-to-noise ratio (SNR) and unparalleled performance in
the presence of all noise sources—the biggest challenge faced by
touchscreen designs. Gen4 also has the lowest active power
consumption, unparalleled tracking accuracy and the fastest refresh
rates. It provides full support for major mobile operating systems
including Win8 and Android.
The new CY8CTMA1036 uses a 32-bit ARM® Cortex™ core, and offers
65 sensing I/O channels with support for up to 1036 nodes on the
screen, 35 percent more than any other single-chip solution.
Additional sensing channels are essential for greater accuracy,
linearity, support for smaller sized fingers and the ability to
resolve multiple fingers close together.
“We’re getting the same positive reaction from tablet
manufacturers as we did from the handset sector,” said Dhwani Vyas,
Vice President of Cypress’s User Interface Business Unit.
“Customers are excited to apply the benefits of Gen4’s noise
immunity, low power and superior performance in a single-chip
package to their tablet designs. We’re sampling multiple customers
now and expect to start production shipments by the end of this
quarter.”
Breakthrough Noise Elimination
The Gen4 family was designed from the ground up to deliver the
world’s highest SNR in real world applications. It is the first and
only touchscreen IC that delivers built-in 10V Tx to drive the
touch panel at 10V. 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 family further raises the SNR bar as the first
touchscreen device family to completely eliminate display noise in
hardware. Gen4’s patent-pending Display Armor™ offers unprecedented
immunity to noise from every type of display, even noisy low-cost
displays such as ACVCOM LCDs. This allows touchscreen designers to
make their products thinner by removing the air gap between the
display and the sensor, and also less expensive by removing the
shield layer in the sensor. Display Armor allows Gen4 to operate
seamlessly with direct lamination, on-cell and in-cell stackups,
regardless of the display chemistry.
World’s Fastest and Lowest Power Touchscreen
Controller
In addition to unmatched noise performance, the Gen4 platform
offers the world’s lowest active power consumption of 2 mW, and a
deep sleep mode that only draws 1.8 uW with wake-up via address
match on the COM port. Shortened battery life is a common issue for
smartphones and other portable touchscreen devices. Gen4 gives OEMs
another tool to help solve this problem. 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. This level of performance is enabled by
the 32-bit ARM® Cortex™ core at the heart of the Gen4 products. The
Gen4 family enables unlimited touch performance, while providing
the industry’s best accuracy and linearity of 0.2 mm.
The Gen4 family also offers features that only TrueTouch can
deliver, including 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. Cypress’s unique, patent-pending ability to
switch dynamically between self-capacitive and mutual-capacitive
sensing methods in application enables these differentiating
features. Cypress now has over 250 issued and pending patents
pertaining to touchscreens. More information, including multiple
videos, is available at touch.cypress.com.
Touchscreen Leadership
Cypress’s touch sensing portfolio is the industry’s broadest and
most well adopted, encompassing both TrueTouch and CapSense®
solutions. The Gen4 family is the latest in a string of touchscreen
firsts from Cypress, the acknowledged industry leader in touch
sensing. Examples include:
- Cypress was the first to deliver
tracking of unlimited touches.
- Cypress was the first to deliver a true
single-layer sensor solution for capacitive performance at
resistive prices.
- The new Gen4 family, as well as prior
generations, is offered in the world’s smallest CSP packages for
important space savings in handsets.
- Cypress is still the only company to
offer the patent-pending self and mutual capacitance sensing on the
same chip, enabling the development of advanced features like
waterproofing, support for 1mm stylus, and hover without increased
material or spatial costs.
- TrueTouch is designed to work with
major mobile platforms, including Android and Windows® 8.
