1. General Description
HE83755 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. Users
can choose any one of combination among 2048 dots LCD Driver + 16 Bit I/O Port...1792 dots LCD
Driver + 24 Bit I/O Portetc. which is determined by mask options. The built-in OP comparator can be
used with light, voice, temperature and humility sensor or used to detect the battery low. The 7-bit
current-type D/A converter and PWM drive output provide the complete speech output mechanism. The
built-in DTMF generator can generate the PSTN dialing tone directly. The 512K bytes ROM size can be
used in the storage of large speech data, image and text etc. It can be applicable to the medium systems
such as small-scale dictionary, data bank, pocket dialer, automatic dialer machine, medium level
educational toy, lower second voice recording system or used with external command mode SRAM or
Flash RAM for higher second voice recording etc.
The instruction sets of HE80000 series are quite easy to learn and simple to use. Only about thirty
instructions with four-type addressing mode are provided. Most of instructions take only 3 oscillator
clocks (machine cycles). The performance of HE83755 is enough for most of battery operation system.

5. Oscillators
The MCU is equipped with two clock sources with a variety of selections on the types of oscillators to
choose from. System designer can select oscillator types based on the cost target, timing accuracy
requirements etc. Crystal, Resonator or the RC oscillator can be used as fast clock source, components
should be placed as close to the pins as possible. The type of oscillator used is selected by mask option
MO_FXTAL.
FXI (Bi-direction), FXO (Output)
Mask Option
Description
MO_FXTAL
0: RC Oscillator.
1: Crystal Oscillator.
MO_FCK
0: Fast clock disable
1: Fast clock enable
SXI (Bi-direction), SXO (Output)
Two types of oscillator, crystal and RC, can be used as slow clock selectable by mask option
MO_SXTAL. If used time keeping function or other applications that required the accurate timing, crystal
oscillator is recommended. If the timing accuracy is not important, then RC type oscillator can be used to
save cost.
