RX320240D

Product catalog summary

General Specification
The RX320240D module features a dimension of 94.7 x 83.3 x 8.6 mm, a view area of 81.4 x 61.0 mm, and an active area of 76.785 x 57.11 mm. It consists of 320 x 240 dots with a dot size of 0.223 x 0.225 mm and a dot pitch of 0.238 x 0.24 mm. The module operates with a duty cycle of 1/240 and uses an LED backlight. The integrated circuit used is RA8835.

Interface Pin Function
The module includes 20 pins with various functions: VSS (Ground), VDD (Power supply for Logic), VO (Operation voltage for LCD driving), A0 (Data/Instruction select), WR/RD (Write/Read signal), DB0-DB7 (Data bus lines), CS (Chip Enable), RES (Reset), VEE (Positive voltage output), SEL1 (Interface Select), A and K (Power supply for backlight).

Contour Drawing & Block Diagram
The contour drawing specifies dimensions with a tolerance of ±0.3 mm. The block diagram illustrates the layout of the pins and the dot matrix configuration.

Absolute Maximum Ratings
The operating temperature ranges from -20 to +70°C, and the storage temperature ranges from -30 to +80°C. The supply voltage for logic is between -0.3 and 7.0 V, and the input voltage ranges from -0.3 to VDD+0.3 V. The supply voltage for the LCD is between 0 and 32 V.

Electrical Characteristics
The supply voltage for logic is typically 3.3 V, with a range from 3.0 to 3.6 V. The supply voltage for the LCD varies with temperature: 22.7 V at -20°C, 23.0 V at 25°C, and 23.3 V at 70°C. Input high voltage is between 0.5VDD and VDD, while input low voltage is between VSS and 0.2VDD. Output high voltage is VDD-0.4 V, and output low voltage is VSS+0.4 V. The supply current is 63.5 mA.
