ISSI ANNOUNCES ACQUISITION OF THE WIRED CONNECTIVITY BUSINESS OF SIGMA DESIGNS, INC.
Integrated Silicon Solution, Inc. (ISSI) has announced that it has entered into a definitive agreement with Sigma Designs, Inc. (“SD”) under which ISSI will acquire Sigma Designs Israel S.D.I. Ltd., which is the wired connectivity business of SD and a leader in G.hn and home connectivity solutions.
The transaction is subject to customary closing conditions and is expected to close later this month.
G.hn technology offers a single standard for connecting networked devices over any existing wired infrastructure (power-line, coax and phone-line) to meet the demands of multi-screen and expanded bandwidth content in today’s homes. This business supplies standards- based chipsets that enable carrier-class distribution of broadband digital content over all three types of existing wires for distribution of Triple Play and IPTV in the home. The business sells its technology to OEMs who build solutions for multimedia home networking and multi-dwelling unit (MDU) broadband access markets and its chipsets are used in set-top boxes, residential gateways, optical network terminators and Ethernet bridges
The acquisition of SD’s wired connectivity business will strengthen ISSI’s product portfolio by adding specialty networking technology to expand ISSI’s future growth opportunities. The connectivity products will expand ISSI’s customer base to new home networking and Smart Grid customers. Smart Grid services outside the home include Advanced Metering Infrastructure (AMI), Automated Meter Management (AMM), and Automated Meter reading (AMR).
Nadav Katsir, SD’s Vice President and Manager, Home Connectivity Unit, commented, “The connectivity team is excited to be joining ISSI and leveraging its global capabilities. We remain committed to serving our customers and growing our business.”
KY Han, ISSI’s President and CEO, commented, “We are excited to add the world class connectivity team to our Analog and Mixed Signal product line. This product line adds a new dimension to ISSI’s product base to create a new platform for growth. Our customers will benefit from the G.hn technology since it offers high performance and unique solutions enabling cost effective communication in emerging applications such as in Home Networking and Smart Grid.

ISSI Announces Full Function LED Driver IC For Automotive Interior Lighting
ISSI Full Function LED Driver IC For Automotive Interior Lighting
150mA Linear LED Driver with Push-Button Input Combined with Courtesy Signal
Integrated Silicon Solution, Inc. (ISSI), a leader in advanced memory and analog IC solutions, has announced a single chip solution for automotive interior lighting.
The IS32LT3175 is a feature-rich AEC-Q100 certified linear LED driver enabling reduced BOM count for low-cost and compact designs.
Key features and benefits of the IS32LT3175 include:
- Reduced BOM: LED driver with theatrical dimming in one small 8 pin SOP package resulting in 65% less components requiring less printed circuit board area.
- Linear LED Driver: Low-noise, low-EMI, linear current source adjustable from 10~150 mA into one or more LEDs.
- Switch Input: Integrates switch debounce and latching logic to enable use of low cost momentary contact switch. The switch On/Off state is held during start-stop operation when voltage drops below 6V for a short period of time.
- Local or Remote: Can be controlled remotely by the automobile’s microcontroller or locally with a momentary contact switch. The local switch has priority over the remote microcontroller providing the user with direct control of the LED lamp.
- No Microcontroller: Advanced LED performance can be adjusted with simple resistors, eliminating the need for a microcontroller.
- AEC-Q100: Meets stress testing specifications making it suitable for use in the harsh automotive environment with guaranteed operation from –40°C to +125°C.

ISSI Launches Next Generation Family of Matrix FxLED Driver ICs
IS31FL3741, IS31FL3742 drive up to 351 LEDs and support individual LED lighting effect functions for creating a configurable array of color animation visuals with fault reporting
Integrated Silicon Solution, Inc. (ISSI), a leader in advanced memory and analog IC solutions, has announced a family of high performance LED drivers, IS31FL3741 & IS31FL3742 to support LED matrices consisting of 351 & 180 LEDs respectively.
With the introduction of these two devices, ISSI expands its FxLED driver family to offer the widest selection of matrix LED driver solutions for gaming, consumer and white goods applications.
ISSI’s LED matrix architecture provides designers with flexibility in controlling individual LEDs or an array of LEDs resulting in simplified color & dimming adjustment and lighting zone selection for a large array of LEDs.
The IS31FL374x family of matrix LED drivers integrates many advanced features such as a configurable matrix (row/column) architecture, global dimming, individual LED peak current control registers, individual LED PWM control registers, individual LED open/short fault detection; all accessible via a fast 1MHz I2C compatible bus interface.
Each LED has its own corresponding control and fault status register to provide individual LED color and dimming effects, de-ghosting and fault reporting for enhanced overall system performance and reliability.
LED matrix architectures typically experience a “ghosting effect” where an LED remains dimly ON due to a residual charge in the LED array matrix.
The IS31FL374x family eliminates this residual charge and therefore the ghosting effect.
“The growth in video gaming peripherals requires ever more customizable RGB LEDs synchronized to the gaming environment,” said Ven Shan, ISSI VP of Analog products. “ISSI’s latest family of matrix FxLED drivers provides peripheral designers with a feature rich, fast and flexible control of a large number LEDs; simplifying the integration and synchronization of the LED lighting effects for the high end gaming platforms.”
The signals required to support 351, or 180 LEDs are driven in a row/column multiplexed architecture which reduces device package size while resulting in fewer traces and minimal PCB area. The added advantage of driving LEDs in this row/column configuration is that no LED will ever be reverse-biased at any time thereby improving LED longevity. For applications requiring a huge array of LEDs, up to 4 IS31FL374x devices can be connected with one I2C bus.
Key features and benefits of the IS31FL3741, IS31FL3742:
- High LED Count – Up to 351 LEDs (39×9) matrix
- 1/9 Duty Cycle Scanning – Higher average LED brightness
- Theatrical Dimming – Three selectable smooth dimming scenarios for each LED
- De-Ghost Function – Guarantees LED is either fully ON or OFF
- Global Current Set – 256 steps Global Current Setting
- 8-bit Dot Correction – Individual 256 DC peak current control steps
- 8-bit Grayscale Control – Individual 256 PWM control steps
- Fault Detection – Individual LED open or short detection with system notification
- High Speed Interface – 1MHz I2C-compatible interface provides fast access to LED registers
- Industrial Temperature – Operating temperature range -40°C to +125°C for high reliability
