R8C/L35C Group, R8C/L36C Group, R8C/L38C Group, R8C/L3AC Group 5. Electrical Characteristics

Apr 15, 2011
Notes:
1. Vcc = 4.0 V to 5.5 V, single chip mode, output pins are open, and other pins are Vss.
2. XIN is set to square wave input.
3. Vcc = 5.0 V
4. VLCD = Vcc, external division resistors are used for VL4 to VL1, 1/3 bias, 1/4 duty, f(FR) = 64 Hz, SEG0 to SEG55 are selected, and segment
and common output pins are open. The standard value does not include the current that flows through external division resistors.
5. The internal voltage multiplier is used, bits LVLS3 to LVLS0 in the LCR1 register = 1011b, 1/3 bias, 1/4 duty, f(FR) = 64 Hz, SEG0 to SEG55
are selected, and segment and common output pins are open.
