MAXREFDES117# reference design from Maxim Integrated Products, Inc. (NASDAQ: MXIM). This optical heart-rate module reference design incorporates red and infrared LEDs, a sensor, power subsystem, and logic level translation. Measuring 13mm x 13mm, this tiny, low- power board can be placed on a finger or earlobe to accurately detect heart rate and SpO2 via personal wearable devices. The module works with both Arduino® and ARM® mbed™ platforms for ease of design, testing, and system integration, and includes eight “tap pads” for quick electrical connection to a development platform and/or wearable garment. Maxim, already a leader in bio-sensing applications with more than 200 million units shipped, now provides this simple platform to enable all developers. The reference design includes three Maxim chips: a pulse oximeter and heart-rate sensor (MAX30102); an efficient, low-power step- down converter (MAX1921); and an accurate level translator (MAX14595). The design requires only a single 2V to 5.5V supply and typically dissipates less than 5.5mW when using the included firmware. Key Advantages Ease-of-Use: Compatible with both Arduino and ARM mbed platforms to simplify set-up Fast Time-to-Market: Includes open-source heart-rate and SpO2 algorithm; BOM; schematics; layout, and Gerber files to accelerate development Versatile: Can be used for product development or as a module in the final design Commentary “Maxim is providing a basic open-source heart-rate and SpO2 algorithm as part of the firmware, and we encourage users to build upon it,” said David Andeen, Director of Reference Designs at Maxim Integrated. “Makers and developers can use this either as a ‘starting point’ reference design, or embed any variation in their final product or project.” “As we continue to bring innovative designs to our customers, we have started a collaboration with Maxim—this is the first product we manufactured and built with them,” said Joey Jiang, Marketing Product Director, Seeed Studio. “We’re excited to see what people will make with this reference design.” Availability and Pricing The MAXREFDES117# reference design is available for $20 at Maxim’s website, select franchised distributors, and http://bit.ly/Seeed_MAXREFDES117. Hardware and firmware design files, as well as test data, are provided free and available online. For information on other reference designs, visit http://bit.ly/

Intersil Unveils 14-Channel Programmable Gamma Buffer for Infotainment and ADAS Displays Automotive-grade ISL76534 delivers lowest power and highest accuracy gamma calibration to enable bright, high-contrast LCD displays Milpitas, Calif., Oct. 10, 2016 – Intersil Corporation (NASDAQ: ISIL), a leading provider of innovative power management and precision analog solutions, today announced the industry’s lowest power 14-channel programmable gamma buffer for automotive TFT-LCD displays. The automotive-grade ISL76534 delivers the highest accuracy gamma calibration to ensure consistent brightness and color matching of every LCD panel inside a vehicle. The ISL76534 is ideal for next generation LCDs designed for infotainment displays, advanced driver assistance system (ADAS) smart mirrors and instrument cluster displays. The robust ISL76534 provides engineers with one Vcom and 14 gamma channels with 10-bit resolution for fine-tuning the gamma curve. LCD panels that are not properly gamma corrected often appear bleached out or too dark. Engineers employ the ISL76534 to calibrate and store the gamma curve, guaranteeing that each LCD powers up and displays eye-pleasing images. The ISL76534’s internal EEPROM stores the factory- calibrated gamma and Vcom reference values, and enables significantly higher reliability than competitive devices by offering 10,000 write cycles and 20 years of data retention at 105°C. The ISL76534 circuit architecture makes it easier to use than competitive solutions. No power-supply sequencing is required–either analog or digital power
