描述
RL78/L12 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: 1.60 μANote 2, internal voltage boost: 1.19 μA, and capacitive split: 0.68 µA. With a lineup of 32 to 64-pin products supporting up to 280 segments, these microcontrollers are perfect for small devices with built-in LCD panels such as small 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.
