4 Bit Microcontroller

tenx technology

GENERAL DESCRIPTION

The TM6820 is an embedded high-performance 4-bit microcomputer with LCD 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, Resistance to Frequency

Converter(RFC), EL panel driver, LCD driver, look-up table, watchdog timer and key matrix

scanning circuitry in a signal chip.

FEATURE

1. Low power dissipation.

2. Powerful instruction set (142 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. Memory capacity.

ꢀꢁROM capacity

ꢀꢁRAM capacity

x 16 bits.

x 4 bits.

4. LCD driver output.

ꢀꢁ5 common outputs and 35 segment outputs (up to drive 175 LCD segments).

ꢀꢁ1/2 Duty, 1/3 Duty, 1/4 Duty or 1/5 Duty is selected by mask option.

ꢀꢁ1/2 Bias or 1/3 Bias is selected by mask option.

ꢀꢁSingle instruction to turn off all segments.

ꢀꢁSegment outputs(SEG1~35) could be defined as CMOS or P_open drain output

type by mask option.

5. Input/output ports.

ꢀꢁPort IOA

ꢀꢁPort IOB

ꢀꢁPort IOC

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 SEG32~35.

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

6. 8 level subroutine nesting.

7. Interrupt function.

ꢀꢁExternal factor 2 (INT pin, Port IOC).

ꢀꢁInternal factor 4 (Pre-Divider, Timer1, Timer2 & RFC).

8. Built-in EL panel driver.

ꢀꢁELC, ELP (Muxed with SEG28, SEG29).
