RL78/L1C

High-function LCD microcontrollers with USB 2.0/rapid charging support for sensor modules and healthcare devices

 

RL78/L1C microcontrollers have a built-in segment LCD driver and USB 2.0 function. 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 consumption (*1): external resistance division: 1.76 μA (*2), internal voltage boost: 1.23 μA, and capacitive split: 0.74 µA. They support USB high-speed battery charging (Battery Charging Specification 1.2) and come in a lineup of 80/100-pin, maximum 416 segment products. These microcontrollers can be used in sensor modules and healthcare devices as well as home appliances and measurement devices.

(Remarks)
(*1) Current (typ.) at 1/3 bias, subclock operation, HALT mode, and RTC operation
(*2) Resistance value for external resistance division = 1000 kΩ
