Low Power Application (Use of ADC, DTC and ELC at Snooze mode) for FPB-RA2E1 and FPB-RA2E2
●This application note describes the features of RA2E1 and RA2E2 MCUs that are useful for low-power operation, typically required for logging data for long durations. The FPB-RA2E1 or FPB-RA2E2 kit is used for creating such a low-power data logging system. The functionality demonstrated here is typically required in products such as fitness trackers, fleet tracking devices, and so forth. The data logger uses the 12-bit A/D Converter (ADC), Data Transfer Controller (DTC), Asynchronous General-purpose Timer (AGT), Real-time Clock (RTC) (Applicable for FPB-RA2E1), Event Link Controller (ELC), Data Operation Circuit (DOC), and Low-power Mode (LPM). The Snooze mode and Software Standby mode are used to reduce power consumption by minimizing the CPU operation time. Application projects use the Integrated Development Environment e2 studio IDE and Flexible Software Package (FSP) provided for the RA family.
●This application note has been changed to a simple function from application note RA2L1/RA2E1 Group Low Power Application Example (Data Logger) (R30AN0384) so that operation can be confirmed with FPB-RA2E1 and FPB-RA1E2.
