Description

The ML9203-xx is a 5 ´ 7 dot matrix type vacuum fluorescent display tube controller driver IC which displays characters, numerics and symbols of a maximum of 16 digits ´ 2 lines.
Dot matrix vacuum fluorescent display tube of ML9203-xx 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.
