HD66773R
Description
The HD66773R is a controller driver LSI compliant to 132RGB x 176-dot graphics display on TFT LCD
panel in 262,144 colors. The HD66773R’s bit-operation functions, 18-bit high-speed bus interface, and
high-speed RAM-write function enable efficient data transfer and high-speed update of graphics RAM data.
The HD66773R operates with low voltage up to 2.2V for power supply. The HD66773R incorporates TFT
gate-drive and source-drive circuits, a step-up circuit to generate LCD drive voltage, and power supply
circuits such as breeder resistor and voltage follower for LCD drive, which enable a configuration of LCD
module only with external elements such as capacitors and resistors. The HD66773R supports 8-color-
display and standby modes, which enable precise power control by software. These features make this LSI
the best solution for medium or small sized portable products such as digital cellular phones, bi-directional
pagers, or small PDA, which support WWW browser, where long life battery is major concern.
