General Description
The HTG12G0 is a 4-bit single chip microcon-
troller specially designed for LCD product ap-
plications.
• _{Internal timer overflow and RTC interrupt}
• _{16 kinds of programmable sound effects}
• _{Halt function and wake-up feature}
reduce power consumption
• _{One-level subroutine nesting}
• _{8-bit table read instruction}
• _{Up to 4.0µs instruction cycle with 1.0MHz}
system clock at VDD=3V
• _{95 powerful instructions}
It is ideally suited for applications requiring
low power consumption, with many LCD seg-
ments such as calculator, scale, subsystem con-
troller, hand-held LCD products and electronic
appliances.
