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 builtin 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.
