A.HE83715 Introduction
HE83715 is a member of Jess Tech HE80000 series 8-bit CMOS micro-controller. This IC can
share the LCD pin and I/O pin (From 128-dot of LCD driver + 16 Bit I/O Port ... 64-dot of LCD
driver + 32 Bit I/O Port)etc. The built-in OP comparator can be used with (lightvoice
temperaturehumility) 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 64K ROM Size
can be used in the storage of speech (20 seconds at 3K bytes per second), graphic, text etc. This
IC is applicable to the small/medium systems such as Data Bank, Medium Class Educational toy,
Lower Second Voice recording system etc..
The HE83715 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.
