7. 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.

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.

Above limited value is set up according to RoHS.
2.Process for RoHS requirement：
(1) Use the Sn/Ag/Cu soldering surface；the surface of Pb-free solder is rougher than we used
before.
(2) Heat-resistance temp.：
Reflow：250℃,30 seconds Max.；
Connector soldering wave or hand soldering：320℃, 10 seconds max.
(3) Temp. curve of reflow, max. Temp.：235±5℃；
Recommended customer’s soldering temp. of connector：280℃, 3 seconds.
16. Storage
1. Place the panel or module in the temperature 25°C±5°C and the humidity below 65% RH
2. Do not place the module near organics solvents or corrosive gases.
3. Do not crush, shake, or jolt the module.
