NJU6820 Datasheet | New Japan Radio

DESCRIPTION The NJU6820 is a STN LCD driver with 40mon x 128RGB-segment in 4096-color. It consists of 384(128x RGB)-segment segment, 40mon drivers, serial and parallel MPU interface circuits, internal power supply circuits, gradation palettes and 61,440-bit for graphic display data RAM. Each segment driver outputs 16-gradation level out of 32-gradation level of gradation palette. Since the NJU6820 provides a low operating voltage of 1.7V and low operating current, it is ideally suited for battery-powered handheld applications. s PACKAGE OUTLINE NJU6820CJ s FEATURES q q q q q q q q q q q q q 4096-color STN LCD driver LCD drivers 40 mons, 128 RGB-segments, Display data RAM (DDRAM) 61,440-bit for graphic display Color display mode 16 gradation level out of 32 gradation level of gradation palette Black & white display mode 40 x 384 pixels in 16 gradation level or 40 x 384 pixels in B&W display 256-color driving mode 8/16bit Parallel interface directly-connective to 68/80 series MPU Programmable 8- or 16-bit data bus length for display data 3-/4-line Serial interface Programmable duty and bias ratios Programmable internal voltage booster (maximum 5-times) Programmable contrast control using 128-step EVR Various instructions Display data read/write, Display ON/OFF, Reverse display ON/OFF, All pixels ON/OFF, Column address, row address, N-line inversion, Initial display line, Initial line, Read-modify-write, Gradation mode control, Increment control, Data bus length, Discharge ON/OFF, Duty cycle ratio, LCD bias ratio, Boost level, EVR control, Power save ON/OFF, etc Internal voltage regulator Low operating current Low logic supply voltage 1.7V to 3.3V LCD driving supply voltage 5.0V to 18.0V C-MOS technology Rectangle out look for COG Package Bumped chip / TCP q q q q q q q 02/08/26 -1- NJU6820 s PAD LOCATION DMY102 DMY100 DMY1 DMY2 VSSA DMY3 SEL68 DMY4 VDDA DMY5 PS DMY6 VSSA DMY7 RESB DMY8 DMY9 DMY10 CSB DMY11 DMY12 DMY13 RS DMY14 DMY15 DMY16 WRB DMY17 DMY18 DMY19...
