TDK has announced the world's smallest module for the latest Bluetooth 4.1 specification. The ultra-compact (3.5x3.5x1.0mm) SESUB-PAN-D14580 module reduces the footprint by over 60% compared to modules with discrete components. With a voltage supply of 3.0V, its current consumption is only 5.0mA when transmitting, 5.4mA when receiving and 0.8µA in standby mode.
Thanks to its miniature size and low current consumption, the Bluetooth module is suitable for use in battery-powered wearable devices, where small size, light weight and low power consumption are essential. The module also features an integrated DC/DC converter.
The SESUB-PAN-D14580 module, which is based on TDK's SESUB (Semiconductor Embedded in SUBstrate) integration technology, features an embedded DA14580 Bluetooth 4.1 chip from Dialog Semiconductor. All terminals of the discrete chip are available, allowing full use of chip functions. The quartz oscillator, capacitors and various other peripheral components are mounted on the same substrate, enabling the record miniaturisation. In addition, the modular approach simplifies the hardware design process.
Bluetooth has established itself as the wireless communication standard of choice to connect wearable devices to smartphones, tablets or PCs, for example. The SESUB-PAN-D14580 implements Bluetooth 4.1 LE, the latest version of this standard that is also known as Bluetooth Smart, which made it possible to reduce power consumption to about one fourth of conventional Bluetooth devices.
The SESUB-PAN-D14580 is designed for use in healthcare, sport and fitness devices: physical activity monitors, thermometers, blood pressure monitors, blood oxygen monitors, blood sugar monitors and heart rate monitors; wearable devices: smart bracelets, watches, rings, glasses and clothing; home and entertainment devices: beacon systems, thin card devices, remote controls, sensor tags, toys, lighting systems and more; and computer peripheral devices such as mouses, keyboards, stylus pens and presentation pointers.
