HE85750
HE80000 SERIES
1. General Description
HE85750 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. Users
can chose 32 COM for any one of combination among 【2048 dots LCD Driver + 12 Bit I/O Port】…
【1280 dots LCD Driver + 36 Bit I/O Port】etc.. or 48COM for any one of combination among 【2304
dots LCD Driver + 12 Bit I/O Port】…【1152 dots LCD Driver + 36 Bit I/O Port】etc.. The built-in OP
comparator can be used with (light、voice、temperature、humility) sensor and used as battery low detection.
And the 7-bit current-type D/A converter and PWM device provide the complete speech output
mechanism. The 256KB ROM and 2KB RAM Size can be used in the storage of large speech data,
graphic, text etc. It can be applicable to the medium systems such as Small-Scale Dictionary, Data Bank,
Medium Level Educational Toy, Lower Second Voice Recording System etc..
The instruction set of HE85750 is easy to learn and simple to use. Only 32 instructions with four
addressing modes are provided. Most instructions take only 3 oscillator clocks. The processing power is
adequate for most battery operation systems.
