LOPEC 2016 will be taking place from April 5–7 in Munich, Germany, where the latest products, technologies, and trends in printed electronics will be on display. Smartwatches, fitness trackers, and other wearable tech will be among the focal points at this year’s international trade fair, and they will also be on the agenda at the LOPEC Conference, where top-class speakers from companies such as adidas will be in attendance.

Miniature SMT tact switch has operating force choices
Offering a package size of just 4.5 x 4.5mm, the TL3305 miniature SMT tact switch has a surface mount termination, and two operating forces to choose from. The switch from E-Switch has an operating lifecycle of up to 500,000. It also offers multiple actuator lengths from 3.8 to 7.0mm.
Applications include wearable technology, telecommunications, consumer electronics, audio/visual, medical devices, testing and instrumentation, computer and peripherals.
Electrical rating is 50mA at 12V DC, with a contact resistance of 100m? (max). Insulation resistance is 100M? (min) at 100V DC, with a dielectric strength of 250V AC for one minute. Operating temperature is -20 to 70°C.

PSoC architecture has ARM Cortex-M0 core for interface options
Embedded designs can be delivered to market quicker, and with the ability to develop user interfaces, using the PSoC 4 programmable SoC, says Cypress Semiconductor.
The chip has a 32bit ARM-Cortex-M0 core, adding up to 256kbyte flash memory, 98 general purpose I/Os, 33 programmable analogue and digital blocks, a USB device controller, and a CAN interface. The PSoC 4 L-Series delivers up to 13 programmable analogue blocks including four high-performance op amps, four current-output DACs, two low-power comparators, a 12bit SAR ADC and dual CapSense blocks with up to 94 capacitive-sensing channels. The analogue blocks enable engineers to create on-chip, custom analogue front ends to support new end-product features, without increasing product costs, size or power consumption, says the company.
TDK’s miniature Bluetooth module is available from Mouser Electronics
Distributor Mouser Electronics now stocks TDK’s SESUB-PAN-D14580 Bluetooth v4.1 module. This compact, Low Energy (LE) micro module is the world’s smallest module for Bluetooth Smart devices, says the company. The 3.5 × 3.5 × 1mm module is based on the company’s proprietary Semiconductor Embedded in Substrate (SESUB) technology, which is claimed to result in a reduction of 60% in size, compared to modules using discrete components. The single-mode module’s footprint and low current consumption make it ideal for battery-powered wearable devices where small size, light weight, and low power consumption are essential, points out the distributor.
The module integrates a Dialog Semiconductor DA14580 Bluetooth 4.1 chip, 32bit ARM Cortex-M0 microcontroller, and DC/DC converter onto a thin substrate, along with all peripheral circuitry including a 16MHz crystal, inductor, and capacitor. All I/O from the substrate layers are routed to a BGA footprint on the module’s bottom surface. Interfaces include UART, SPI, and I2C, to implement connectivity.
The low-power module requires a voltage supply of 3.0V, and consumes only 5.0mA when transmitting, 5.4mA when receiving, and 0.8µA in standby mode. Output power is rated at 0dBm (typical), with a communication range of 10m, depending on line of sight and antenna characteristics.
