NJU6627 10-CHARACTER 3-LINE DOT MATRIX LCD CONTROLLER DRIVER with KEYSCAN FUNCTION  GENERAL DESCRIPTION The NJU6627 is a Dot Matrix LCD controller driver for 10-character 3-line with icon display in single chip. It contains voltage converter and regulator bleeder resistance, Keyscan circuit, CR oscillator, microprocessor interface circuit, instruction decoder controller, character generator ROM/RAM, high voltage operation common and segment drivers, and others. The character generator ROM consisting of 7,840bits stores 224 kinds of character font, Each 1,120 bits CG RAM and Icon display RAM can store 32 kind of special character displayed on the dot matrix display area or 100 kinds of Icon display area. The 23-common(21 for character, 2 for Icon) and 50-segment drivers operate 10-character 3-line with 100 Icon LCD display. The 16th display contrast control function is incorporated. Therefore, only simple power supply circuit on chip operates the contrast adjustment easily. The complete CR oscillator requires external capacitor and resistor. The serial interface which operates by 1MHz, communicates with external MCU.  PACKAGE OUTLINE NJU6627C  FEATURES  10-character 3-line Dot Matrix LCD Controller Driver  Maximum 100 Icon Display  Serial Direct Interface with Microprocessor  Display Data RAM 30 x 8 bits :Maximum 10-character 3-line Display  Character Generator ROM 7,840bits :224 Characters for 5 x 7 Dots  Character Generator RAM  Icon Display RAM 1,120bits :32 Patterns (5 x 7 Dots) Maximum 100-Icons  High voltage LCD Driver 23-common / 50-segment  Duty and Bias Ratio 1/23, 1/16 duty, 1/5 bias  Useful Instruction set Clear Display, Address Home, Display ON/OFF, Display blink, Address shift, Character Shift, Keyscan ON/OFF cont. e.t.c.  24-Key input(4x6 Keyscan)  Power on Initialization / Hardware Reset  Bleeder resistance on chip  Software contrast control(16-step)  Voltage Booster Circuits (2-time)  Oscillation Circuit on-chip (External CR)  Operating Voltage 4.5 to 5.5V  Package Outline  C-MOS Technology Bare Chip Ver.2019-01-31 -1- NJU6627  PAD LOCATION 75 76 TOP VIEW Y X 51 50 100 1 Chip Center Chip Size Chip Thickness PAD Size PAD Pitch Sub Striate : X=0m, Y=0m : X= 4.50 mm, Y= 4.61 mm : 400m  25 m : 90.0 m x 90.0 m : 134m (Min.) :P 26 25 -2- Ver.2019-01-31 NJU6627  PAD COODINATES PAD No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 PAD NAME V4 V3 V2 V1 VLCD VOUT C1+ C1VCI VDD OSC1 REQ DATA SCL CSb RESETb VSS K1 K2 K3 K4 K5 K6 S1 S2 S3 S4 COMMK1 COM8 COM9 COM10 COM11 COM12 COM13 COM14 SEG1 SEG2 SEG3 SEG4 SEG5 SEG6 SEG7 SEG8 SEG9 SEG10 SEG11 SEG12 SEG13 SEG14 SEG15 X= m -2007.3 -1862.5 -1717.7 -1572.9 -1428.1 -1158.4 -1018.4 -878.4 -738.4 -497.6 -345.8 -204.0 -17.2 142.6 286.6 430.6 596.8 817.4 951.4 1098.6 1232.6 1379.8 1513.8 1743.2 1923.2 1978.6 1978.6 2088.0 2088.0 208.
