C8051F700 Enables Robust, Cost-Effective Capacitive Touch Sensing AUSTIN, Texas--(BUSINESS WIRE)--Mar. 2, 2009--
Silicon
Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today announced the introduction of
its C8051F7xx
family of high pin-count MCUs for cost-sensitive, high I/O embedded
systems. This family is the first to offer a new, patent-pending touch
sensing feature that is robust, accurate, responsive and easy to
configure. Offering up to 54 general purpose I/O pins and a 25 MIPS 8051
CPU, the C8051F7xx family brings a high level of processing power and
flexibility to applications such as industrial controls, security
systems, residential HVAC, home appliances, keyboards, cash machines and
fax/printer/scanner front panels.
The industry’s fastest touch sense on-chip peripheral uses a
capacitance-to-digital converter (CDC) with a 40 us acquisition time
that when combined with the 25 MIPS CPU on the C8051F7xx enables
sophisticated human interface functions, even when large arrays of touch
sense elements are used. To combat issues in electrically noisy
environments, the CDC offers best-in-class noise immunity, insuring
reliable performance. With up to 32 touch sensing inputs, featuring
wake-on-touch, the MCU can be placed in a power saving mode and wake
quickly upon touch to save overall system power in applications. An
intuitive software GUI allows fast and easy configuration. And, an API
library is provided for all common touch sense configurations such as
virtual buttons, wheels and sliders.
The C8051F7xx family also provides a number of analog features on board,
further reducing system cost. A highly accurate 10-bit successive
approximation (SAR) analog-to-digital converter (ADC) with on-chip
voltage reference and temperature sensor provides best-in-class analog
capability for measurement and control. Up to 54 general purpose I/Os
are offered to be used as ADC voltage measurement inputs, capacitive
touch-sense inputs and/or digital communications I/Os. A calibrated two
percent oscillator with guaranteed accuracy over the full MCU voltage
supply and temperature range eliminates the need for an external
crystal. In addition, the C8051F7xx family offers byte-erasable EEPROM
with 100,000 write/erase cycle endurance guaranteed for storage of
frequently updated data.
“Silicon Labs’ mixed-signal capability has enabled a new level of
performance in capacitive touch-sensing,” said Mark Thompson, vice
president and general manager of Silicon Labs’ MCU products. “The
C8051F7xx family enables our customers to cost-effectively add
best-in-class touch sensing capability to any product requiring higher
I/O count and high performance analog peripherals.”
Silicon Labs offers a full suite of industry-leading tools to help speed
design and accelerate market entry with the C8051F7xx. A complete,
low-cost professional development kit includes everything required to
immediately begin system design including IDE, target board, cables and
power supply. A Silicon Labs GUI is provided for easy and intuitive
setup of the capacitive touch sense peripheral to get the desired
configuration and performance in minutes. A separate capacitive touch
sense evaluation kit provides fast and easy evaluation of the Silicon
Labs capacitive sensing solution. To enter to win a free development kit
