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.
Wearable
Microcontrollers are graphic-centric with ARM Cortex-M7 core
Opening up possibilities for portable or wearable devices, smart building and industrial controllers, smart appliances and medical equipment, the STM32F767 and STM32F769 microcontrollers have up to 2Mbyte flash and 512kbyte RAM.
32bit flash microcontrollers double battery life
Based on the ARM Cortex-M0+ processor, the S1C31W74 microcontroller is sampling. This is Epson’s first in a new series of energy-efficient microcontrollers with integrated 32bit flash memory.
According to the company, the combination of the energy-efficient ARM Cortex-M0+ processor, and the company’s own low leak process and circuit technology helps to enable powerful microcontrollers with modest power requirements, thus extending battery life.
The S1C31W74 consumes only 900nA in RTC mode and 150µA/MHz in run mode, and can operate up to two times longer on battery power than one of the company’s original core 32bit flash microcontrollers. This energy efficiency is a step closer, says the company, to realising smart watches that do not require recharging and IoT terminals for environmental monitoring applications, where power consumption is a critical factor.
The microcontroller is a single chip, housed in a 1mm thick VFBGA8HX-181 package. The IC includes an LCD driver that can directly display up to 2,304 dots, a USB 2.0 full-speed device controller, 512kbytes of flash memory, and 128kbytes of RAM. It is also offered as a bare chip.
An optional evaluation kit includes an evaluation board, debug probe and an IDE, based on IAR Embedded Workbench for ARM.
The microcontrollers are sampling now, with volume production scheduled for July 2016.

Sensor can speed time to market for integrated modules
System designers can speed time to market for wearable and healthcare products, says Maxim Integrated Products, with the MAX30102 pulse oximeter and heart rate integrated sensor module. The integrated pulse oximetry and heart rate monitor module integrates red and IR LEDs to modulate LED pulses for oxygen saturation (SpO2) and heart rate measurements.
