General Description
The HTG12N0 is the processor from HOLTEK’s
4-bit stand alone single chip microcontroller
specially designed for LCD display and time
piece product applications.
• _{8-bit table read instruction}
• _{Five working registers}
• _{Internal timer overflow}
• _{One level subroutine nesting}
• _{RC oscillator and 32768Hz crystal oscillator}
• _{8-bit timer with internal or external clock}
source
• _{Sound effect circuit}
It is ideally suited for multiple LCD time piece
low power applications among which are calcu-
lators, scales, calendar and hand held LCD
products.
