## DATASHEET STATEMENT 

**1.** The following icons are absolutely designed by Midas independently in 2007-SEP. They are not in common use in the LCD industry yet but just used for marking out Midas products’ characteristics quickly and simply without any special meaning. Midas reserves the composing right and copyright. No one else is allowed to adopt these icons without Midas approval. 

**2.** The ISO9001 logo used in this document is authorized by SGS (www.sgs.com). Midas had already successfully passed the strict and professional ISO9001:2000 Quality Management System Certification and got the certificate (No.: CN07/00404) 

**3.** The technologies/techniques/crafts which denoted by the following icons are not exclusively owned by Midas, but also shared by Midas LCD strategic cooperators, however all these technologies/techniques/crafts have been finally confirmed by Midas professional engineers and QC department. 

**4.** As the difference in test standard and test conditions, also Midas insufficient familiarity with the actual LCD using environment, all the referred information in this DATASHEET (including the icons) only have two functions: 4.1: providing quick reference when you are judging whether or not the product meets your requirements. 4.2: listing out definitely the tolerance. 

SAMPLE APPROVAL document rather than consider this DATASHEET as the standard for judging whether or not the LCD meets your requirements. Once you instruct Midas to a mass-production without definite demand for providing sample before, Midas will disclaim all responsibility if the mass-production is proved not meeting with your requirements. 

**5.** The sequence of the icons is random and doesn’t indicate the importance grade. 

**6.** Icons explanation

## 10. Function Description 

The LCD display Module is built in a LSI controller, the controller has two 8-bit registers, an instruction register (IR) and a data register (DR). 

The IR stores instruction codes, such as display clear and cursor shift, and address information for display data RAM (DDRAM) and character generator (CGRAM). The IR can only be written from the MPU.  The DR temporarily stores data to be written or read from DDRAM or CGRAM.  When address information is written into the IR, then data is stored into the DR from DDRAM or CGRAM.  By the register selector (RS) signal, these two registers can be selected. 

**==> picture [373 x 92] intentionally omitted <==**

**----- Start of picture text -----**<br>
||||
|---|---|---|
|RS|R/W|Operation|
|0|0|IR write as an internal operation (display clear, etc.)|
|0|1|Read busy flag (DB7) and address counter (DB0 to DB7)|
|1|0|Write data to DDRAM or CGRAM (DR to DDRAM or CGRAM)|
|1|1|Read data from DDRAM or CGRAM (DDRAM or CGRAM to DR)|

**----- End of picture text -----**<br>


## **Busy Flag (BF)** 

When the busy flag is 1, the controller LSI is in the internal operation mode, and the next instruction will not be accepted.  When RS=0 and R/W=1, the busy flag is output to DB7.  The next instruction must be written after ensuring that the busy flag is 0. 

## **Address Counter (AC)** 

The address counter (AC) assigns addresses to both DDRAM and CGRAM 

## **Display Data RAM (DDRAM)** 

This DDRAM is used to store the display data represented in 8-bit character codes.  Its extended capacity is 80×8 bits or 80 characters.  Below figure is the relationships between DDRAM addresses and positions on the liquid crystal display.

## **Character Generator ROM (CGROM)** 

The CGROM generate 5×8 dot or 5×10 dot character patterns from 8-bit character codes. See Table 2. 

## **Character Generator RAM (CGRAM)** 

In CGRAM, the user can rewrite character by program.  For 5×8 dots, eight character patterns can be written, and for 5×10 dots, four character patterns can be written. 

Write into DDRAM the character code at the addresses shown as the left column of table 1. To show the character patterns stored in CGRAM.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
