LG Innotek Develops Bluetooth Smart Module That Carries Little Or No Size Penalty Compared To A Discrete Solution And Requires No RF Design Expertise To Use

LG

Based on the multiple award-winning Nordic Semiconductor nRF51822 SoC, the LG 4403 Bluetooth Smart system-in-package (SiP) module measures just 5.3 x 4.7 x 1.0mm and so is small enough to fit into any current or next generation smartphone, tablet, or computer appcessory or sensor no matter how miniaturized

Ultra low power (ULP) RF specialist Nordic Semiconductor ASA recently announces that Korean electronics materials and components giant, LG Innotek, has developed a Nordic nRF51822 SoC-basedBluetooth Smart (previously known as Bluetooth low energy) module that carries little or no size penalty compared to a discrete (individual component-built) solution and requires no RF expertise to employ.

The LG 4403 module measures just 5.3 x 4.7 x 1.0mm in size and is supplied in an LGA package small enough to fit into any current or next-generation Bluetooth Smart smartphone, tablet, or computer appcessory including the smallest wearable, smart watch, sports, health, and Internet of Things (IoT) devices.

The module includes in addition to the multiple award-winning Nordic Semiconductor nRF51822 and it's 32-bit ARM Cortex M0 microprocessor, 256 kB of Flash memory, and full range of analog and digital peripherals (including GPIO, ADC, SPI, I2C and UART): a 32 MHz high stability X-Tal quartz oscillator, fully-matched RF matching circuit, 19 GPIOs (general purpose input/outputs), and can run from 1.8 to 3.6V power source.

Power consumption is also optimized for ultra low power operation with a claimed typical performance of 10.5 mA for transmission (TX), 13mA for reception (RX), and 0.6 µA for deep sleep 'off' mode. RX sensitivity is quoted at –93dBm at 1Mbps data transfer rates, and TX power –20 up to +4dBm.

"LG Innotek has a long history in module development stretching all the way back to TV tuners in the 1970s and more recently variable connectivity modules such as Wi-Fi, Bluetooth, and LTE for the mobile, TV, and automotive industries," explains Mr. Kwangjae Park, Senior Research Engineer for LG Innotek. "But because we are also an electronics component manufacturer, we used that expertise to achieve extreme levels of miniaturization and integration in our modules that developers would often struggle to match even if designing with separate discrete components."

"Bluetooth Smart modules allow customers to develop products and devices without being experts in RF or Bluetooth wireless technology," comments Geir Langeland, Nordic Semiconductor's Director of Sales & Marketing. "But because Bluetooth Smart wireless technology is employed in some of the smallest devices and sensors – including those intended to be worn or carried by the end-user – size and miniaturization are key design parameters."
