GENERAL DESCRIPTION
This version:
ML9203-xx
Jun. 1999
5
樓
7 Dot Character
樓
16-Digit
樓
2-Line Display Controller/Driver with Character RAM
The ML9203-xx is a 5
樓
7 dot matrix type vacuum fluorescent display tube controller driver IC
which displays characters, numerics and symbols of a maximum of 16 digits
樓
2 lines.
Dot matrix vacuum fluorescent display tube drive signals are generated by serial data sent from
a micro-controller. A display system is easily realized by internal ROM and RAM for character
display.
The ML9203-xx has low power consumption since it is made by CMOS process technology.
-01 is available as a general-purpose code.
Custom codes are provided on customer's request.
