68 / 106 page  R01DS0011EJ0100 Rev.1.00 Page 68 of 102 Dec 21, 2010 R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, R8C/LA8A Group 5. Electrical Characteristics Notes: 1. Vcc = 1.8 V to 2.7 V, single chip mode, output pins are open, and other pins are Vss. 2. XIN is set to square wave input. 3. Vcc = 2.2 V 4. VLCD = Vcc, external division resistors are used for VL3 to VL1, 1/3 bias, 1/4 duty, f(FR) = 64 Hz, SEG0 to SEG26 are selected, and segment and common output pins are open.The standard value does not include the current that flows through external division resistors.
