4 Bit Microcontroller

GENERAL DESCRIPTION

The TM8713 is an embedded high-performance 4-bit microcomputer with LCD/LED driver.

It contains all the necessary functions, such as 4-bit parallel processing ALU, ROM, RAM,

I/O ports, timer, clock generator, dual clock operation, EL panel driver, LCD driver, look-up

table, watchdog timer and key matrix scanning circuitry in a signal chip.

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.

ꢀꢁROM capacity

ꢀꢁRAM capacity

1536

x 16 bits.

x 4 bits.

5. Input/output ports.

ꢀꢁPort IOA

4 pins (with internal pull-low), muxed with SEG24~27.

4 pins (with internal pull-low), muxed with SEG28~31.

4 pins (with internal pull-low / low-level-hold), muxed with SEG32 ~

SEG35.

ꢀꢁPort IOB

ꢀꢁPort IOC

IOC port had built-in input signal chattering prevention circuitry.

6. 8 level subroutine nesting.

7. Interrupt function.

ꢀꢁExternal factors

ꢀꢁInternal factors

(INT pin, Port IOC & KI input).

(Pre-Divider, Timer1).

8. Built-in EL panel driver.
