IS31FL3800 & IS31FL3801 provide flexible RGB Matrix with up to 128 LED Drivers and 256 Brightness levels and up to 11 capacitive sense touch key control
Lumissil Introduces a Family of Smart Matrix LED Drivers with Integrated Touch-Key control
MILPITAS, Calif., Aug. 04, 2020 (GLOBE NEWSWIRE) — LUMISSIL, a Division of ISSI, today announced a family of Smart Matrix LED Drivers with Integrated Touch Keys control designed for Human Interface Device (HID) applications. The family consisting of IS31FL3800 & IS31FL3801 that integrate matrix LED driver with capacitive touch controller enabling an all-in-one turn-key solution for simplified & reliable implementation of Human-Machine visual and control interface in home appliances, IoT devices and Industrial Process control panels. Supplied with a standard code and command protocol enables easy prototyping and rapid implementation into any product.
“Lumissil’s expertise in advanced LED drivers combined with our Cap-Sense technology, provides our customers with a highly integrated and compact solution for a variety of human-machine display panel interfaces,” said Ven Shan, VP of Marketing at Lumissil Microsystems. “The IS31FL3800/01 family extends Lumissil’s LED drivers portfolio to Smart HMI solution combining lightning, visual data, touch buttons and audio feedback in applications such as home appliances, IoT and industrial control panels.”
IS31FL3800 & IS31FL3801, integrated LED drivers provide up to 128 LED matrix configurations at high average current. Accurate color rendition is enabled by 256-level PWM, dot-correction and global current adjustment. Noise reduction is achieved by spread spectrum and 180 degree phase delay. Up to 11 capacitive touch keys with individually adjustable sensitivity are available in the IS31FL3800/01. Unused touch key pins can be configured for selecting I/O functions. Applicable for a variety of touch key interfaces (button, wheel, slider, wheel, proximity, etc.) and materials (glass, plastic, wood etc.), with power-saving modes for auto-sleep & wake on touch making it highly versatile and easy to design in.
IS3FL3800 and IS3FL3801 are supplied as turn-key products with a standard code. A host microcontroller communicates with them through I2C interface and uses a command set to configure and control the LED drivers, cap-sense touch buttons, GPIO pins and other embedded functions.
A comprehensive development package includes documentation, demo boards, reference evaluation boards and calibration GUI. The calibration GUI enables simple device configuration in one flow for configuring I/O ports, calibrating Capacitive touch keys and saving configuration directly to a file or target device with no additional programing. The Configurable evaluation board enables easy access to connect the customer target product LEDs and Capacitive touch keys to the main board for quick target device operation evaluation. In addition, product debugging support is available from ISSI’s application engineers.
