Chapter 1 Overview
1 – 3
OPTION B (D): 1.5 V (3.0 V), With regulator
circuit for LCD bias
OPTION A (C): 1.5 V (3.0 V), Without regulator
circuit for LCD bias
j. LCD driver
Segment-type LCD drivers built-in
The following pin modes can be specified for L0 to L63 by the mask option generator setting. (Refer to the
“MOGTOOL Mask Option Generator User’s Manual”.)

*1 Can be selected as a COM pin in 1-bit unit (L0 to L3, L36 to L39). A maximum of four pins can
be selected as COM pins.
*2 Can be selected as an output port in 4-bit unit (L32 to L35).
N-channel open drain output or CMOS output can be specified for each bit.
Number of segments : 64 (60 SEG.
×
4 COM. Max.)
Duty : 1/1 to 1/4 duty (fixed to 1/2 duty when at 1/2 bias)
Bias : Selectable as 1/2 or 1/3 bias
OPTION B, OPTION D: Regulator circuit used (0.95/1.90/2.85 V)
OPTION A, OPTION C: Regulator circuit not used (directly connected to the power
supply voltage (1.5/3.0/4.5 V))
Frame frequency : 64 Hz (at 1/1, 1/2, 1/4 duty), 85.3 Hz (at 1/3 duty)
Contrast : OPTION B, OPTION D: Adjustable up to 16 levels (in steps of 0.03 V)
OPTION A, OPTION C: Adjustment not available
Display modes : Selectable as all-ON mode/all-OFF mode/power down mode/normal display mode
k. RC oscillation type A/D converter
•
2 channels (time sharing is used)
l. System reset function
•
System reset by RESET pin (2 kHz sampling function provided)
•
System reset that resets the system when the combined bits (2, 3, or 4 bits) of the input port (Port 0) are
all set to a “H” level
(Whether system reset is disabled or enabled, the number of bits to be combined, and the polarity can be
specified by mask option. Refer to the “MOGTOOL Mask Option Generator User’s Manual”.)
2 bits : P0.0, P0.1
3 bits : P0.0, P0.1, P0.2
4 bits : P0.0, P0.1, P0.2, P0.3
m. Battery check
•
Applies to the OPTION C and OPTION D. Does not apply to the OPTION A and OPTION B.
•
Function that detects battery low voltage
•
Selection of judgment voltage by software (LD1 and LD0 bit settings of BLDCON)
