Renesas – RL78/G1D Intelligent Bluetooth® Smart MCUs


Low-power RL78 Microcontroller and Bluetooth Low Energy (BLE) wireless technology increase battery life and accelerate Bluetooth connected device development

Outstanding Tx/Rx Power Efficiency

State-of-the-art radio technology enables reliable communications with low current consumption.

Efficient Connection Technology

RL78/G1D MCUs prioritize current consumption at near distances or communication range at far distances.

Simplified RF Design

High level of integration simplifies RF design and reduces BOM count.


  • Bluetooth Smart v4.1 connectivity supported in embedded and modem modes
  • Peak Tx current of 4.3 mA and peak Rx current of 3.5 mA
  • ‘RF Adaptable Technology’ automatically optimizes power consumption versus communication range
  • High integration minimizes BOM cost; Balun, on-chip 32 KHz oscillator
  • Industry-leading support tools shorten time to market
  • BT SIG qualified stack plus documented test procedure facilitate radio certification
  • Firmware-over-the-air (FOTA) capability enables convenient application upgrades in the field
