Overview
Description
RL78/L13 microcontrollers have a built-in segment LCD driver. Three LCD driving voltage generation methods (external resistance division, capacitive split, and internal voltage boost) are supported, corresponding to a variety of segment LCD panels. They realize low current consumptionNote 1: external resistance division: 1.61 μANote 2, and internal voltage boost: 1.42 μA, and capacitive split: 0.77 µA. With a lineup of 64/80-pin products supporting up to 376 segments, these microcontrollers are perfect for devices with built-in LCD panels such as home appliances and healthcare devices.
Note 1: Current (typ.) at 1/3 bias, subclock operation, HALT mode, and RTC operation.
Note 2: Resistance value for external resistance division = 1000 kΩ.
