E2C0041-19-64 ¡ Semiconductor ¡ Semiconductor ML9203-xx GENERAL DESCRIPTION This version: ML9203-xx Jun. 1999 5 ¥ 7 Dot Character ¥ 16-Digit ¥ 2-Line Display Controller/Driver with Character RAM 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 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. Pr el im in ar y FEATURES Logic power supply (VDD) : 3.3 V± 10% or 5.0 V± 10% VFD tube drive power supply (VDISP) : 20 to 60 V VFD driver output current (VFD driver output can be connected directly to the VFD tube. No pull-down resistor is required.) - Segment driver (SEGA1 to A35, SEGB1 to B35) Only one driver output is high : –5 mA (VDISP=60V) All the driver outputs are high : –350 mA (VDISP=60V) - Segment driver (ADA, ADB) : –20 mA (VDISP=60V) - Grid driver (COM1 to 16) : –50 mA (VDISP=60V) Content of display SEGA1 to SEGA35 and ADA - CGROM_A 5¥7 dots : 240 types (character data) - CGRAM_A 5¥7 dots : 16 types (character data) - ADRAM_A 16 (display digit) ¥ 1 bit (symbol data; can be used for a cursor.) - DCRAM_A 16 (displa...
