Dot Matrix VFD Display Controller/Driver
Preliminary
Overview
The LC75710NE series products are dot matrix VFD
controller/driver LSIs that display characters, numbers,
and symbols. These LSIs generate dot matrix VFD drive
signals based on serial data sent from a microprocessor,
and allow display systems to be implemented easily using
the built-in character generator ROM and RAM.
The LC75710NE series products are fabricated in a
CMOS process and can contribute to achieving low-power
operation in user applications.
Features
• 5 × 7 dot matrix VFD display controller/driver
(Driver outputs can be connected directly to VFD
devices: pull-down resistors are not required.)
• Display technique: Dynamic lighting technique
• Display digits: 1 to 16 digits (programmable)
• Display control data
CGROM: 5 × 7 dots, 160 characters
CGRAM: 5 × 7 dots, 8 characters
ADRAM: 16 × 8 bits
DCRAM: 64 × 8 bits
• Instruction functions
Display on/off control
Display shift
Display blink
Intensity adjustment (dimmer)
• Serial data input (DI, CL, and CE pins)
• Built-in reset circuit
• 64-pin flat package
Differences between the LC75710NE,
LC75711NE, and LC75712E
• The data in the built-in character generator ROM
(CGROM) differs between these products. All other
functions are identical.

G1 to G16: Display digit specification
Each bit Gn (where n is an integer between 1 and 16) specifies that the corresponding grid output pin Gn be turned
on when that bit (Gn) is 1.
This instruction is used to specify the display on/off control operation. Not only can an arbitrary digit be specified,
but MDATA and ADATA can also be specified.
3. Display shift .........................................<Shifts the display.>
Code

0 0 1 0 * M A R/L * * * * * * * * * * * * * * * *
*: Don’t care.
M, A: Specifies the data to be shifted.
MA
Shift operating state
0 0 Neither MDATA nor ADATA are shifted.
0 1 Only ADATA is shifted.
1 0 Only MDATA is shifted.
1 1 Both MDATA and ADATA are shifted.
R/L: Shift direction specification
R/L
0 Right shift
1 Left shift
Shift direction
4. Grid register load .................................<Specifies the number of digits displayed.>
Code

The AA4/G16, AA5/G15, AA6/G14, AA7/G13, and AA8/G12 anode/grid output pins function as grid output pins if
between 12 and 16 digits are selected. Also, this instruction must be executed prior to turn the display on since the
value of the grid register is undefined immediately after power is applied.
