The HD66750/1 is a 128 x 128 dot graphics LCD controller and driver LSI that displays four monochrome grayscales.
The HD66750/1 is a dot‑matrix graphics LCD controller and driver LSI that provides a 128 × 128‑dot display with four monochrome grayscale levels. It includes a 16‑/8‑bit high‑speed bus interface and bit‑operation functions such as write‑data mask, bit rotation and logic operations, enabling efficient graphics processing.
The device offers low‑power operation with a supply voltage of 1.8 V to 3.6 V, a booster that can generate up to seven times the LCD drive voltage, and a 64‑step contrast adjuster. Power‑saving modes include standby and sleep, as well as programmable drive duty ratios, making it suitable for battery‑driven portable products such as cellular phones, pagers and PDAs.
