Character RAM
This RAM stores either ASCII character data or a UDC RAM address.
Flash RAM
This is a 1 x 8 RAM which stores Flash data.
User-Defined Character RAM
(UDC RAM)
This RAM stores the dot pattern for custom characters.
User-Defined Character
Address Register
(UDC Address Register)
This register is used to provide the address to the UDC RAM when
the user is writing or reading a custom character.
Control Word Register
This register allows the user to adjust the display brightness, flash
individual characters, blink, self test, or clear the display.
Display Internal Block
Diagram
Figure 1 shows the internal block
diagram of the HDSP-210X/
-211X/-250X displays. The CMOS
IC consists of an 8 byte Character
RAM, an 8 bit Flash RAM, a 128
character ASCII decoder, a 16
character UDC RAM, a UDC
Address Register, a Control Word
Register, and refresh circuitry
necessary to synchronize the
decoding and driving of eight 5 x
7 dot matrix characters. The
major user-accessible portions of
the display are listed below:
Character Ram
Figure 2 shows the logic levels
needed to access the
HDSP-210X/-211X/-250X
Character RAM. During a normal
access, the CE = “0” and either
RD = “0” or WR = “0.” However,
erroneous data may be written
into the Character RAM if the
address lines are unstable when
CE = “0” regardless of the logic
levels of the RD or WR lines.
Address lines A
0
-A
2
are used to
select the location in the Charac-
ter RAM. Two types of data can
be stored in each Character RAM
location: an ASCII code or a UDC
RAM address. Data bit D
7
is used
to differentiate between the ASCII
character and a UDC RAM
address. D
7
= 0 enables the ASCII
decoder and D
7
= 1 enables the
UDC RAM. D
0
-D
6
are used to
input ASCII data and D
0
-D
3
are
used to input a UDC address.
