Electrical Description
Pin Function
Description
RESET (RST, pin 1)
Initializes the display.
FLASH (FL, pin 2)
FL low indicates an access to the Flash RAM and is unaffected by the
state of address lines A3-A4.
ADDRESS INPUTS
Each location in memory has a distinct address. Address inputs (A0-A2)
(A0-A4, pins 3-6, 10)
select a specific location in the Character RAM, the Flash RAM or a
particular row in the UDC (User-Defined Character) RAM. A3-A4 are
used to select which section of memory is accessed. Table 1 shows the
logic levels needed to access each section of memory.

CLOCK SELECT
Used to select either an internal (CLS = 1) or external (CLS = 0) clock source.
(CLS, pin 11)
CLOCK INPUT/OUTPUT
Outputs the master clock (CLS = 1) or inputs a clock (CLS = 0) for slave
(CLK, pin 12)
displays.
WRITE (WR, pin 13)
Data is written into the display when the WR input is low and the
CE input is low.
CHIP ENABLE (CE, pin 17)
Must be at a logic low to read or write data to the display and must go
high between each read and write cycle.
READ (RD, pin 18)
Data is read from the display when the RD input is low and the CE
input is low.
DATA Bus (D0-D7,
Used to read from or write to the display.
pins 19, 20, 23-28)
GND (SUPPLY) (pin 15)
Analog ground for the LED drivers.
GND (LOGIC) (pin 16)
Digital ground for internal logic.
VDD (POWER) (pin 14)
Positive power supply input.
