Renesas Electronics has developed a new wireless solution that supports the Bluetooth Smart Near Field Wireless communication standard, the RL78 / G1D Microcontroller Group (MCU). These devices were developed by combining Bluetooth Low Energy Low Energy Radio Frequency Transceiver Technology (BLE), which was demonstrated by the company at the International Solid State Circuits Conference (ISSCC) in February 2015. And industrial MCU expertise and on-chip peripherals required for wireless communications.
By using an evaluation kit and a Bluetooth-SIG-qualified protocol stack, the new MCU enables system designers to perform an initial evaluation of wireless characteristics and communication behavior. The new MCU also provides PC GUI tools to easily operate these components. These will enable customers to easily develop Bluetooth Smart applications and reduce the time required for development while effectively utilizing the development environment and software resources.
BLE is a near-field wireless communication technology that has great potential for connecting smartphones and various other devices. In addition to smartphones, it is also suitable for devices linked via serial communication technology (such as UART) and for communication between units in a single device. Eliminates the need for wired connections between such devices, providing greater design freedom and simplifying maintenance. Therefore, this technology has the potential to bring about major changes in embedded devices.
The RL78 / G1D MCU incorporating Bluetooth Smart was developed by combining the ultra-low-power RL78 MCU that has been widely adopted in the consumer and industrial fields, as well as the announcement of the much-anticipated Bluetooth low energy transceiver technology. . At the ISSCC in February 2015.
The RL78 / G1D's current consumption is the lowest in the industry (3.5mA at reception and 4.3mA at transmission), which greatly reduces power consumption, which is a key consideration for wireless devices. The newly added adaptive radio frequency technology adjusts the power consumption during wireless operation to the optimal level to match the communication distance. This greatly reduces the power consumption of near-field wireless communications and is complemented by on-chip integration of most of the components required for antenna connection, helping to reduce external component costs.
Renesas positions the new RL78 / G1D as a product that contributes to the near-field wireless communications market, which is expected to grow with the arrival of a more energy-efficient "smart society" and the Internet of Things. Renesas said that Renesas intends to continue to provide a series of easy-to-use products to meet market demand.
