CMOS IC
1/8 to 1/10 Duty Dot Matrix LCD
Display Controllers/Drivers
Overview
The LC75810E and LC75810T are 1/8 to 1/10 duty dot
matrix LCD display controllers/drivers that support the
display of characters, numbers, and symbols. In addition to
generating dot matrix LCD drive signals based on data
transferred serially from a microcontroller, the LC75810E
and LC75810T also provide on-chip character display
ROM and RAM to allow display systems to be
implemented easily.

Block Functions
•
AC (Address counter)
AC is a counter that provides the DCRAM address.
The address is automatically modified internally, and the LCD display state is retained.
•
DCRAM (Data control RAM)
DCRAM is the RAM that is used to store display data expressed as 8-bit character codes. (These character codes are
converted to 5 × 7, 5 × 8, or 5 × 9 dot matrix character patterns using CGROM or CGRAM.)
DCRAM has a capacity of 64 × 8 bits, and can hold 64 characters. The table below lists the correspondence between the
6-bit DCRAM address loaded into AC and the display position on the LCD panel.

CGROM (Character generator ROM)
CGROM is the ROM that is used to generate the 240 kinds of 5 × 7, 5 × 8, or 5 × 9 dot matrix character patterns from
the 8-bit character codes. CGROM has a capacity of 240 × 45 bits. When a character code is written to DCRAM, the
character pattern stored in the CGROM corresponding to the character code is displayed at the position on the LCD
corresponding to the DCRAM address loaded into AC.
CGRAM (Character generator RAM)
CGRAM is the RAM to which user programs can freely write arbitrary character patterns. Up to 16 kinds of 5 × 7, 5 ×
8, or 5 × 9 dot matrix character patterns can be stored. CGRAM has a capacity of 16 × 45 bits.
ALATCH (Additional data latch)
ALATCH is the latch that is used to store the ADATA display data for the accessory display. ALATCH has a capacity
of 80 bits, and the stored display data is displayed directly without the use of CGROM or CGRAM.
SC (Scroll counter)
SC is the counter that is used to scroll the display in the left, right, up, or down directions in dot units. Since this
function scrolls in dot units, it implements smooth scrolling.
Reset Function
The LC75810E and LC75810T are reset when a low level is applied to the RES pin at power on and, in normal mode. On a
reset the LC75810E and LC75810T create a display with all LCD panels turned off. However, after a reset applications
must set the contents of DCRAM, ALATCH, and CGRAM before turning on display with a “display on/off control”
instruction since the contents of these memories are undefined. That is, applications must execute the following
instructions.
• Set display technique
• DCRAM data write
• ALATCH data write (If ALATCH is used.)
• CGRAM data write (IF CGRAM is used.)
• Set AC and SC addresses
• Set display contrast (If the display contrast adjustment circuit is used.)
After executing the above instructions, applications must turn on the display with a “display on/off control” instruction.
Note that when applications turn off in the normal mode, applications must turn off the display with a “display on/off
control” instruction. (See the detailed instruction descriptions.)

The data is acquired on the rising edge of the CL signal and latched on the falling edge of the CE signal. When
transferring instruction data from the microcontroller, applications must assure that the time from the transfer of one
set of instruction data until the next instruction data transfer is significantly longer than the instruction execution time.

When n = 32 bits (m = 2): ti = 40.5 µs (when fosc = 300 kHz)
When n = 80 bits (m = 8): ti = 121.5 µs (when fosc = 300 kHz)
When n = 144 bits (m = 16): ti = 229.5 µs (when fosc = 300 kHz)
Note that the instruction execution time of 27 µs and ti values in µs apply when fosc = 300 kHz, and that these times will
differ when the oscillator frequency fosc differs.

AD1 to AD80: ADATA display data
In addition to the 5 × 7, 5 × 8, 5 × 9, 6 × 7, 6 × 8, or 6 × 9 dot matrix display data (MDATA), the LC75810E/T also supports
an accessory display of 5 or 6 segments (ADATA) at each display digit, and allows arbitrary data to be displayed directly
without going through CGROM or CGRAM. The figure below shows the correspondence between that data and the
display. When ADn = 1 (where n is an integer between 1 and 80), the segment corresponding to that data will be turned on.

CTC: Sets the display contrast adjustment circuit state
CTC
Display contrast adjustment circuit state
0
The display contrast adjustment circuit is disabled, and the VLCD0 pin level is forced to the VLCD level.
1
The display contrast adjustment circuit operates, and the display contrast is adjusted.
Note that although the display contrast can be adjusted by operating the built-in display contrast adjustment circuit, it is
also possible to be adjusted by varying the voltage level on the LCD driver block power supply VLCD pin. However, the
level on VLCD0 must be greater than or equal to 4.5V.

LC75810E/T
Notes on the Power On and Power Off Sequences
The following sequences must be observed when power is turned on and off. (See Figure 3.)
• At power on: Logic block power supply (VDD) on → LCD driver block power supply (VLCD) on.
• At power off: LCD driver block power supply (VLCD) off → Logic block power supply (VDD) off.
However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and off at
the same time.

Note that the sample below shows 48 characters of DCRAM data being divided into 3 separate “DCRAM data write” instruction executions in the super-increment mode.
∗25: The data format will have the following format if super-increment mode is used for the “DCRAM data write” instructions (numbers 3 to 50) in sample 1 showing the correspondence between instructions and the display.
Notes ∗24: In sample 1 showing the correspondence between instructions and the display, a 16 digits × 1 line 5 × 7 dot matrix LCD is used, and CGRAM and ALATCH are not used.

Notes ∗26: In sample 2 showing the correspondence between instructions and the display, a 13 digits × 1 line 6 × 7 dot matrix LCD is used, and CGRAM and ALATCH are not used.
∗27: The data format will have the following format if super-increment mode is used for the “DCRAM data write” instructions (numbers 3 to 41) in sample 2 showing the correspondence between instructions and the display.
Note that the sample below shows 39 characters of DCRAM data being divided into 3 separate “DCRAM data write” instruction executions in the super-increment mode.

Specifications of any and all SANYO Semiconductor products described or contained herein stipulate the
performance, characteristics, and functions of the described products in the independent state, and are
not guarantees of the performance, characteristics, and functions of the described products as mounted
in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an
independent device, the customer should always evaluate and test devices mounted in the customer's
products or equipment.
SANYO Semiconductor Co., Ltd. strives to supply high-quality high-reliability products. However, any
and all semiconductor products fail with some probability. It is possible that these probabilistic failures
could give rise to accidents or events that could endanger human lives, that could give rise to smoke or
fire, or that could cause damage to other property. When designing equipment, adopt safety measures
so that these kinds of accidents or events cannot occur. Such measures include but are not limited to
protective circuits and error prevention circuits for safe design, redundant design, and structural design.
In the event that any or all SANYO Semiconductor products (including technical data,services) described
or contained herein are controlled under any of applicable local export control laws and regulations, such
products must not be exported without obtaining the export license from the authorities concerned in
accordance with the above law.
