HE84760
HE80000 SERIES
A. HE84760 Introduction
1
V1.1
HE84760 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd,
User can configure 32COM:
【
3072 dot LCD driver + 16 Bit I/O Port
】
…
【
2304 dot LCD driver + 40 Bit
I/O Port
】
LCD driver
，
or 48COM:
【
3840 dot LCD driver + 16 Bit I/O Port
】
…
【
2688 dot LCD driver +
40 Bit I/O Port
】，
or 64COM:
【
4096 dot LCD driver + 16 Bit I/O Port
】
…
【
2560 dot LCD driver + 40 Bit
I/O Port
】。
Built-in power regulator circuit
，
make the LCD display more stable
。
The built-in OP
comparator can be used with (light, voice, temperature, humility) sensor or battery low detection. A 7-bit
current type D/A converter and PWM device provide the complete speech output mechanism.
。
The
512KB ROM and 4KB RAM can be used as the storage of large speech data, graphic, text etc. It can be
used for Dictionary, Data Bank, Medium Level Educational Toy, Low duration Voice Recording System
etc..
The instruction set are quite easy to learn and simple to use. There are only about thirty instructions
with four-type addressing modes are provided. Most of instructions take only 3 oscillator clocks (machine
cycles), which is the high efficiency and low power MCU.
