HTG2190 --
8-Bit 1024 Pixel Dot Matrix LCD MCU Series (限用產品)
General Description
The HTG2190 is an 8-bit high performance
RISC-like microcontroller capable of driving 1024 pixel
(max.) LCD display. Its single cycle instruction and
two-stage pipeline architecture make it suitable for high
speed applications. The device is suited for use in
multiple LCD low power applications among which are
calculators, clock timer, game, scales, leisure products,
other hand held LCD products and battery operated systems
in particular.
