15. LCD Driver
The TMP86PM29BUG has a driver and control circuit to directly drive the liquid crystal device (LCD). The pins
to be connected to LCD are as follows:
1. Segment output port 32 pins (SEG31 to SEG0)
2. Common output port4 pins (COM3 to COM0)
In addition, C0, C1, V1, V2, V3 pin are provided for the LCD driver’s booster circuit.
The devices that can be directly driven is selectable from LCD of the following drive methods:
1. 1/4 Duty (1/3 Bias) LCD Max 128 Segments(8 segments
