Bringing capacitive-sensing capabilities to cost-sensitive applications, Texas Instruments (TI) has announced an expansion of its MSP430 microcontroller (MCU) family with capacitive touch technology. Developers can use the new MSP430FR2512 and MSP430FR2522 MCUs with integrated capacitive touch to add as many as 16 buttons as well as proximity sensing capability to industrial systems, home automation systems, appliances, power tools, home entertainment, personal audio applications and more.
New MSP430 microcontrollers with capacitive touch technology provide a solution to applications exposed to electromagnetic disturbances, oil, water and grease. The MSP430FR2512 and MSP430FR2522 MCUs deliver International Electrotechnical Commission (IEC) 61000-4-6-certified capacitive sensing MCU-based solutions for applications exposed to electromagnetic disturbances, oil, water and grease. According to TI, the new MCUs offer five times lower power consumption than the competition, supporting proximity sensing and touch through glass, plastic and metal overlays.
TI’s CapTIvate technology adds the benefits of capacitive touch and proximity sensing to applications such as access control panels, cooktops, wireless speakers and power tools. Developers can quickly evaluate capacitive sensing for their applications with the new BOOSTXL-CAPKEYPAD BoosterPack plug-in module that is compatible with the CapTIvate programmer board (CAPTIVATE-PGMR) or TI LaunchPad development kits. The BoosterPack module joins a portfolio of MCUs, easy-to-use tools, software, reference designs and documentation in the CapTIvate Design Center and online CapTIvate technology guide. In addition, developers can find answers and support in the TI E2E Community to speed development with CapTIvate technology.
Production quantities of the MSP430FR2512 and MSP430FR2522 MCUs are available in a 20-pin very thin quad flat no lead (VQFN) package and a 16-pin thin shrink small outline package (TSSOP) starting at $0.69 in 1,000-unit quantities. The CapTIvate BoosterPack plug-in module (BOOSTXL-CAPKEYPAD) is available for $29.99.
Newhaven Display has announced a new HDMI TFT module product line that greatly simplifies the process of connecting to the display. Rather than juggling an FPC ribbon cable with a middle-man controller board, you can connect an HDMI cable from your desired board or computer right into the TFT module. This makes it easy to interface with your display from the development and prototyping stages, all the way into final application production.
The ease-of-use of these new products follows through into touch panel integration as well. For both the resistive and capacitive (PCAP) touch panel options, USB-HID driver recognition is installed. Each of the touch panel modules are also each pre-calibrated in-house to the display they’re mounted on. This means that a simple USB to micro-USB cable just needs to be connected from your board with touch interaction output (such as Raspberry Pi) to the module and your touch interactivity is ready to go immediately.
The product line is made up of three 5″ TFT modules and nine 7″ TFT modules. The 5” versions all come with MVA technology (meaning exceptional 75° viewing at all angles) and your choice of capacitive, resistive or no touch panel. The 7” modules have the same selection of touch screen options, but also allow you to choose between standard, premium or sunlight readable TFT displays.
The boards that make up the new product line are Newhaven Displays’ own design and come with a number of features. On board DC power allows the display to perform at maximum capacity without worrying about a power supply bottleneck from elsewhere. The no-touch panel versions have just two simple connections required to get the module up and running, DC power and HDMI interface. The touch versions need an additional cable to utilize their touch functionality via USB-HID__three cables and you’re ready to go. The hardware is compatible with PC systems (Windows or Linux) as well as Single-Board-Computers (SBCs) like the RaspberryPi and BeagleBone.
The HDMI TFTs’ PCB boards also have four 3.5 mm mounting holes tooled right into the board itself–no bracket or casing required, just pop in any standard M3 screws. To ensure the highest quality and long-lasting performance, these modules use the reliable Texas Instruments TFP401A HDMI/DVI receiver and the TPS61165 LED driver.
On the boards, you’ll also find a switch for Pulse Width Modulation (PWM) to control the brightness output from the display backlight. All hardware is completely open source and available as a useful reference point for any interested user.
The wait for HDMI compatibility is over. Today is the day to start designing your projects with Newhaven Display’s new HDMI TFT Modules. Stop limiting yourself to the hassles of FPC cables and clunky controllers, just grab an HDMI cable and your set up is complete. It’s Newhaven Display’s product quality fused with the reliability of HDMI interface.

Cypress Semiconductor has announced a new series in its Traveo automotive microcontroller family with more memory to support a hybrid instrument cluster with 3D graphics and up to 6 traditional gauges, as well as a head-up display. The highly integrated, single-chip devices in the S6J32xEK series include an advanced 3D and 2.5D graphics engine and provide scalability with Cypress’ low-pin-count HyperBus memory interface. The series continues Cypress’ expansion of its broad automotive portfolio with differentiated system performance via its MCUs, wireless radios, capacitive-touch solutions, memories and Power Management ICs (PMICs).
The Traveo S6J32xEK series integrates up to 4MB of high-density embedded flash, 512 KB RAM and 2 MB of Video RAM, an ARM Cortex-R5 core at 240 MHz performance, a Low-Voltage Differential Signaling (LVDS) video output, a Low-Voltage Transistor-Transistor Logic (LVTTL) video output and a 6x stepper motor control. This combination enables the devices to serve as single-chip solutions to drive two displays. The devices have up to two 12-pin HyperBus memory interfaces that dramatically improve read and write performance of graphical data and other data or code.
A single HyperBus interface can be used to connect to two memories for Firmware Over-The-Air (FOTA) updates, which enable end-users to get software fixes and new features and applications for their vehicles on-the-go. The devices support all in-vehicle networking standards required for instrument clusters, including Controller Area Network-Flexible Data (CAN-FD) and Ethernet AVB. Additionally, the series provides robust security with integrated enhanced secure hardware extension (eSHE) support.
The Traveo S6J32xEK series include 50 channels of 12-bit Analog to Digital Converters (ADC), 12 channels of multi-function serial interfaces and I2S interfaces with an audio to output the complex, high-quality sounds required in today’s instrument clusters. The devices’ support for Ethernet AVB delivers increased bandwidth in multimedia applications and reduced programming time. The S6J32xEK series offers functional safety features to support Automotive Safety Integrity Level (ASIL) B, and the devices feature a wide ambient temperature range of -40˚C to +105˚C. The Traveo family is backed by a comprehensive tools and software ecosystem that simplifies system integration, including AUTOSAR MCAL 4.0.3 support.
The Traveo S6J32xEK series is sampling now and will be in production in the first quarter of 2018. The MCUs are available in a 208-pin and 216-pin thermally enhanced quad flat package (TEQFP).
