The module consists of a newly developed STN type LCD with high contrast and wide viewing angle and CMOS LCD driver and controller. Since the control LSI has built-in display data RAM no external controller is necessary. MECHANICAL DATA FEATURES High contrast and wide viewing angle Light weight / compact dimensions Low power consumtion Built-in display data RAM LED backlight optional Controller / Driver Type - KS 0108 B (2) / KS 0107 (1) - or compatible Temperature compensated Parameter Width x Height x Depth Unit PIN TABLE Outline Dimensions 75 x 52.7 x 7,9 (with LED: 12.5) mm Pin Symbol Description 1 VDD Ground supply (+ 5 V) 2 VSS Ground: 0 V 3 V0* Contrast voltage regulation Effective viewing area 60 x 32.5 mm Dot Size 0.40 x 0.40 mm Dot Pitch 0.43 x 0.43 Weight Approximate 36.5 (without LED) mm g ABSOLUTE MAXIMUM RATINGS Parameter Supply Voltage (Logic) Symbol Min.

R/W = High : CPU to read data appearing at DB0 to DB7. R/W = Low : Data of DB0 to DB7 is written at the falling edge of E. 16 D/I Data or instruction select input D/I = High : Display RAM data on D0-D7. D/I = Low : Instruction data on D0-D7. 17 E Chip Enable. E = High : Read mode. Data appears at DB0 to DB7 as E is at high level. E = Low : Write mode. Data of DB0 to DB7 is latched at the falling edge of E. 18 VEE* Negative power supply voltage for LCD driver 19 NC (A) No Connection or LED Power Supply + 4.2 V (Anode) 20 NC (K) No Connection or LED Power Ground (Cathode) ELECTRICAL CHARACTERISTICS Condition: Ta = 25C, VDD = 5.0 0.25 V Parameter Symbol Min.
