The RA2L1 MCUs can realize significant system cost reductions by utilizing on-chip functions such as the high accuracy (±1.0%) high-speed on-chip oscillator, power-on reset, low-voltage detectors, internal voltage reference, temperature sensor, and data Flash supporting 1 million program/erase cycles, which essentially enable a smaller system footprint by eliminating some external components. Like other Renesas MCUs, the RA2L1 MCUs have quite a few safety functions that allow engineers to design IEC/UL60730 certified applications easily and quickly.
