CHAPTER 1 GENERAL DESCRIPTION
1-1. GENERAL DESCRIPTION
The TM8727 is an embedded high-performance 4-bit microcomputer with LCD driver. It
contains all of the following functions in a single chip: 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.
1-2. FEATURES
1. Low power dissipation.
2. Powerful instruction set (178 instructions).
z Binary addition, subtraction, BCD adjusts, logical operation in direct and index
addressing mode.
z Single-bit manipulation (set, reset, decision for branch).
z Various conditional branches.
z 16 working registers and manipulation.
z Table look-up.
z LCD driver data transfer.
3. Memory capacity.
z ROM capacity
12288 x 16 bits.
Program Address X100~X1FFh reversed for Bank Convert Area.
z RAM capacity
1024 x 4 bits.
4. LCD driver output.
z 9 common outputs and 41 segment outputs (up to drive 369 LCD segments).
z 1/2 Duty, 1/3 Duty, 1/4 Duty, 1/5 Duty, 1/6Duty, 1/7Duty, 1/8Duty or 1/9Duty is selected
by MASK option.
z 1/2 Bias, 1/3 Bias or 1/4 Bias is selected by MASK option.
z Single instruction to turn off all segments.
z COM5~9, SEG1~41 could be defined as CMOS or P_open drain type output by mask
option.
5. Input/output ports.
z Port IOA 4 pins (with internal pull-low), muxed with SEG24~SEG27.
z Port IOB 4 pins (with internal pull-low). muxed with SEG28~SEG31.
z Port IOC 4 pins (with internal pull-low, low-level-hold), muxed with
SEG32 ~ SEG35. IOC port had built in the input signal chattering prevention circuitry.
z Port IOD 4 pins (with internal pull-low), muxed with SEG36 ~ SEG39.
IOD port had built in the input signal chattering prevention circuitry.
6. 8 level subroutine nesting.
7. Interrupt function.
