The world’s smallest Bluetooth SoC: InPlay NanoBeacon SoC IN100 in 2.0×1.1mm WLCSP package

world smallest bluetooth soc IN100 WLCSP

InPlay has just announced a Wafer Level Chip Scale Package (WLCSP) for its NanoBeacon SoC IN100, making it the world’s smallest Bluetooth System-on-a-Chip (SoC) at just 2.0 x 1.1 x 0.35mm. The NanoBeacon IN100 is not new per se, and we covered the still tiny Bluetooth SoC when writing about Sparkfun NanoBeacon Bluetooth 5.3 module based on the DFN8 package measuring 2.5×2.5mm. The highlights include its low-code/no-code interface and an ultra-low power consumption of below 1 uW. InPlay NanoBeacon SoC IN100 specifications: Memory – 4 KB SRAM +  4 Kbit OTP memory Bluetooth 5.3 compliant Beacon Modes: Proprietary, BT, Google Eddystone, and Apple iBeacon compliant 2.4GHz RF frequency band, MedRadio band (2.36GHz) Programming-free and firmware-less design Long-range transmission: up to several hundred meters Security Authentication of beacon ID Privacy of advertising payload Supply voltage range – 1.1V ~ 3.6V (Single 1.5V coin battery support) Power consumption Sub-uW power consumption for […]
