DATA SHEET
MOS INTEGRATED CIRCUIT
µ PD16314
DOT CHARACTER VFD CONTROLLER/DRIVER
DESCRIPTION
The µ PD16314 is a VFD controller/driver capable of displaying a dot matrix VFD. It has 80 anode outputs and 24
grid outputs. A single µ PD16314 can display up to 16C x 2L, 20C x 2L, or 24C x 2L. The µ PD16314 has character
generator ROM in which 248 x 5 x 8 dot characters are stored.
FEATURES
Dot matrix VFD controller/driver
Capable of driving anodes for cursor display (48 units)
80 x 8 bits display RAM incorporated
Capable of alphanumeric and symbolic display through internal ROM (5 by 8 dots)
240 characters plus 8 user-defined characters
Display contents
16 columns by 2(1) rows + 32(16) cursors, 20 columns by 2(1) rows + 40(20) cursors,
or 24 columns by 2(1) rows + 48(24) cursors.
Parallel data input/output (switchable between 4 bits and 8 bits) or serial data input/output can be selected.
On-chip oscillator
Custom ROM supported

Description
When Parallel data transfer is selected, this pin is Register
select.
L: Select instruction register(IR).
H: Select data register(DR).
When serial data transfer mode is selected, this pin is the
strobe input. Data can be input when this signal goes L.
Command processing is performed at the rising edge of this
signal.
When this pin is L, this device is active.
When M68 parallel data transfer mode is selected (E), this
pin is enabled. Data is written at the falling edge.
When i80 parallel data transfer selected (/RD), this pin is a
read-enable pin. When this pin is L, data is output to the
data bus.
When serial data transfer is selected, this pin is the shift
clock input. Data is written at the rising edge.
When M68 parallel data transfer mode is selected (R,/W),
this pin is the data transfer select pin.
L: Write
H: Read
When i80 parallel data transfer mode is selected (/WR), this
pin is written a write-enable pin. Data is written at rising
edge of this signal.
When serial data transfer mode is selected this pin is fixed
to H or L.
When serial data transfer mode is selected, this pin is used
as an I/O pin.
When parallel data transfer mode is selected, this pin is
fixed to H or L. DB0 to DB7
When parallel data transfer mode is selected, these pins
are used as I/O pins.
When 4-bits transfer mode is selected, DB4 to DB7 are
used. Data is transferred starting from the most significant
bit (MSB) and stored sequentially.
L: Initializes all the internal registers and commands.
Anode and grid outputs are fixed to VSS2.
