TM8713 Features
1. Low power dissipation.
2. Powerful instruction set (135 instructions).
Binary addition, subtraction, BCD adjust, logical operation in direct and index addressing mode.
Single bit manipulation (set, reset, decision for branch).
Various conditional branch.
16 working registers and manipulation.
Table look-up.
LCD driver data transfer.
3. LCD/LED driver output.
5 common outputs and 27 segment outputs (up to drive 135 LCD/LED segments).
1/2 Duty, 1/3 Duty, 1/4 Duty or 1/5 Duty for both LCD/LED drivers is selected by MASK option.
1/2 Bias or 1/3 Bias for LCD driver is selected by MASK option.
Single instruction to turn off all segments.
Segment outputs(SEG1~12,21~35) could be defined as CMOS or P_open drain type output by mask option.
4. Memory capacity.
