Renesas Electronics Smart Grid Fault Indicator Unit
Renesas Electronics Smart Grid Fault Indicator Unit is an example of a low-power design system for system implementation. The fault indicator unit uses Renesas' high-performance RA2 MCU series. The unit includes a 16-bit SAR ADC, 24-bit sigma-delta ADC, COMP, system control, touch control, and super low power.
In the data collection unit, the RL78/G13 is a standard function MCU with low power and an abundant lineup for general purpose applications. BLUETOOTH® is used for communication between the two boards. Combined with Renesas' high-performance power and analog solutions, this system can minimize idle quiescent current. This helps save power consumption during standby states.
Features
- Low quiescent power MCU solutions for optimized efficiency
- High performance analog devices for accurate system monitoring
