LG Innotek develops Bluetooth Smart module that measures just 5.3 x 4.7 x 1.0 mm

LG Innotek has developed a Nordic nRF51822 SoC-based Bluetooth 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.

In addition to Nordic Semiconductor nRF51822 and its 32-bit ARM Cortex M0 microprocessor, The module includes 256 kB of Flash memory, and a 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 10.5mA for transmission (TX), 13mA for reception (RX), and 0.6µA for deep sleep 'off' mode. RX sensitivity is quoted at -93dBm at 1Mbps data transfer rates, and TX power -20 up to +4dBm.
