Programmable Color Sequence RGB LED Driver for IoT applications
Self-running with RGB patterns saves power with no processor interaction.
Integrated Silicon Solution, Inc. (ISSI), a leader in advanced memory and analog IC solutions, has introduced the IS31FL3194, latest addition to the company’s innovative line of FxLED RGB drivers.
The IS31FL3194 is a fully programmable 3 channel LED driver supporting a wide range of color rendering capabilities for consumer and industrial IoT applications.
The IS31FL3194 can be programmed through a 400 kHz I2C bus to perform LED light timing sequences and color patterns with gamma correction.
Each of the 3 LED channels can be independently adjusted to 8-bit current levels (40mA max), 8-bit PWM (RGB color mixing), gamma correction, and timing sequences.
These wide range of programmable sequences will continue operating even when the system microcontroller is in standby mode thereby conserving system power.
“As a leading provider of innovative LED driver solutions for the consumer and automotive markets we recognize one of the challenges faced by our customers has been lowering the system power budget,” said Ven Shan, VP of Analog Marketing at ISSI. “We developed the IS31FL3194 with programmable RGB pattern sequences so it can continue driving the LEDs even when the micro is placed in a low power sleep mode. Because the IS31FL3194 takes responsibility of driving the LEDs, this not only saves system power but also frees up the micro to focus on system critical functions.”
The IS31FL3194 is available in a tiny 1mmx1.6mm WCSP-8 package, making it one of the smallest and most highly programmable LED driver solutions in the market today.
The flexible programmability enables one to configure the RGB LEDs to operate either as one RGB group or RG+W group or 3 single color LED in a pre-established pattern.
In addition a low 150mV dropout voltage at 20mA, 0.8mA quiescent current and a 1uA shutdown current makes this an ideal solution for low-power battery applications.
The IS31FL3194 LED Driver can generate pre-programmed colors with patterns that can be used as signals to gain attention or to provide notification or status in wearables, portable medical devices, smart home, smart retail and other emerging IoT applications.

ISSI Introduces 512Mb SPI NOR Flash for Automotive & Industrial Markets
AEC-Q100 Qualified, new device extends range of SPI NOR support from 256Kb way up to 512Mb density
Integrated Silicon Solution, Inc. (ISSI), a leader in advanced memory and analog solutions, has begun sampling production units of automotive grade 512Mb Serial (SPI) NOR Flash.
ISSI’s SPI NOR Flash product supports a wide operating temperature range of -40C to 125C, making it ideal for the next generation automotive, industrial and Internet of Things (IoT) applications.
The 512Mb SPI NOR device exceeds the AEC- Q100 requirements and is PPAP ready.
This new device extends our range of SPI NOR support from 256Kb all the way up to 512Mb density.
The 512Mb SPI NOR is available in multiple package choices, along with KGD (known good die):
- 16-pin SOIC 300mil
- WSON 8×6 mm
- 24-ball TFBGA 6x8mm 5×5 package
ISSI is also working on Multi-Chip Package (MCP) options of SPI NOR Flash and its’ DRAM product line.
Lyn Zastrow, VP of the Automotive Business Unit at ISSI explained, “With the proliferation of SPI NOR in almost every automotive application, this new density extends our range into some of the new high-end ADAS, Infotainment, and Digital Cockpit applications. Unlike many of our competitors, we can offer a SPI NOR solution from a very small density to a very large density. We continue to offer a complete portfolio of every technology.”
“ISSI’s automotive grade SPI NOR Flash support applications with harsh environments that rely on long-term reliable system operation over a wide temperature range”, said Anand Bagchi, Director Marketing at ISSI. “The addition of 512Mb SPI NOR Flash enhances our NOR Flash product line and provides our customers the ultra-reliable high-density SPI NOR option they are looking for.”
In addition to the SPI NOR, ISSI offers ISSI offers a multitude of DRAMs including SDR, DDR2, DDR3 and mobile SDR, LPDDR, LPDDR2; a complete line of both asynchronous and synchronous SRAMs with densities from 64Kb to 72Mb; and a broad portfolio of SPI NAND and parallel NAND Flash, including eMMC. ISSI also has a range of Known Good Die (KGD) memories in its portfolio.
Please contact Allyanz today for further details and support on ISSI’s range of SPI Flash, including samples.
