Product catalog summary

Overview:
The document outlines the technical specifications and handling instructions for the C82A-BW-XW65 Character LCD Module. This module features an 8x2 character display using STN Blue technology and a transmissive LCD panel with a white LED sidelight. It operates on a +5V input voltage and complies with RoHS standards.

Specifications:

Character Format: 5x8 Dots
Display Format: 8 Characters x 2 Lines
Interface: 4/8-bit Parallel
Controller: ST7066
Viewing Direction: 6 o'clock
Temperature Range: Wide

Mechanical Information:

Module Size: 40.0mm L x 35.4mm W
Viewing Area: 30.4mm L x 13.9mm W
Character Size: 2.96mm L x 4.75mm W

Electrical Characteristics:

Power Voltage: 0 to 7.0 V
Operating Temperature: -20 to +70°C
Storage Temperature: -30 to +80°C
Supply Voltage for LCD: 3.8 to 4.6 V
Input Voltage: 4.5 to 5.5 V

Instructions:
The document provides detailed instructions for operating the LCD, including function set, address set, and data transfer instructions. It highlights the necessity of checking the busy flag before executing subsequent instructions.

Handling Precautions:

Avoid mechanical shock and excessive pressure on the display.
Handle the polarizer carefully to prevent scratches.
Ensure proper grounding to prevent static electricity damage.
Adhere to soldering guidelines to avoid module damage.

Operation Precautions:
The viewing angle can be adjusted by varying the LCD driving voltage. Proper handling and operation are essential to maintain the display's integrity and performance.

Additional Specifications:

The applied pulse waveform must be symmetric to prevent electro-chemical reactions that can deteriorate the display. Ensure no DC component remains.
Use the specified operating voltage to avoid shortening the display's lifespan.

Procedures:

Maintain driving voltage within the specified range.
Monitor response time, which increases as temperature decreases.

Norms:

Keep the display within its operational temperature range to prevent color changes.
Ensure temperature and humidity are within specified limits to avoid polarization degradation, polarizer peel-off, or bubble generation.

Recommendations:

For long-term storage above 40°C, maintain relative humidity below 60%.

8. Instructions To overcome the speed difference between the internal clock of ST7066 (or equivalent) and the MPU clock, ST7066 performs internal operations by storing control in formations to IR or DR. The internal operation is determined according to the signal from MPU, composed of read/write and data bus. Instructions can be divided largely into four groups: 1) ST7066 function set instructions (set display methods, set data length, etc.) 2) Address set instructions to internal RAM 3) Data transfer instructions with internal RAM The address of the internal RAM is automatically increased or...

Set the moving direction of cursor and display. I/D: increment / decrement of DDRAM address (cursor or blink) When I/D="high", cursor/blink moves to right and DDRAM address is increased by 1. When I/D="Low", cursor/blink moves to left and DDRAM address is increased by 1. CGRAM operates the same way as DDRAM, when reading from or writing to CGRAM. SH: shift of entire display When DDRAM read (CGRAM read/write) operation or SH="Low", shifting of entire display is not performed. If SH ="High" and DDRAM write operation, shift of entire display is performed according to I/D value. (I/D="high". shift...

This instruction makes DDRAM data available from MPU. When 1-line display mode (N=LOW), DDRAM address is form "00H" to "4FH".In 2-line display mode (N=High), DDRAM address in the 1st line form "00H" to "27H", and DDRAM address in the 2nd line is from "40H" to "67H". Read binary 8-bit data from DDRAM/CGRAM. The selection of RAM is set by the previous address set instruction. If the address set instruction of RAM is not performed before this instruction, the data that has been read first is invalid, as the direction of AC is not yet determined. If RAM data is read several times without RAM address...

9. Cautions and Handling General Precautions: 1. LCD panel is made of glass. Avoid excessive mechanical shock or applying strong pressure onto the surface of display area. 2. The polarizer used on the display surface is easily scratched and damaged. Extreme care should be taken when handling. To clean dust or dirt off the display surface, wipe gently with cotton, or other soft material soaked with isoproply alcohol, ethyl alcohol or trichlorotriflorothan. Do not use water, ketone or aromatics and never scrub hard. 3. Do not tamper in any way with the tabs on the metal frame. 4. Do not make any...
