A.HE83750S Introduction
HE83750S is a member of Jess Tech HE8000 series 8-bit CMOS micro-controller. This IC can
share the LCD pin and I/O pin (From 2048-dot of LCD driver + 16 Bit I/O Port ... 1792-dot of
LCD driver + 24 Bit I/O Port), the combination of the above is selected by Mask Option. It built-
in one internal Op-Amp, application to light, Sound, Temperature and Humidity sensor for
controlling application, one 7-bit D/A converter. Use the built-in 512KByte ROM can store
around large volume of data including voice, graphics and data. One DTMF generator. Suitable
in education toys, data-bank, translator and some mid-to-high end electronic products, Internal
SRAM recording, External SRAM or Flash RAM.
The HE83750S provides a very simple and effective instruction set, each instruction byte
occupies only 1.5 clock cycle time, therefore, it is suitable to apply in the high performance
systems.
