Overview
OKI Semiconductor ML9208-xx 5 × 7 Dot Character × 16-Digit Display Controller/Driver with Character RAM FEDL9208-01 Issue Date: Feb.
23, 2004 GENERAL DESCRIPTION The ML9208-xx is a dot matrix vacuum fluorescent display tube controller driver IC which displays characters, numerics and symbols.
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.
FEATURES • Logic power supply and vacuum fluorescent display tube drive power supply (VDD) : 3.
3 V ±10% or 5.
0 V ±10% • Fluorescent display tube drive power supply (VFL) : VDD –20 V to VDD –42 V • VFD driver output current (VFD driver output can be connected directly to the fluorescent display tube.
No pull-down resistor is required.
) - Segment driver (SEG1 to SEG35) : –6 mA (VFL = VDD –42 V) - Segment driver (AD1 and AD2) : –15 mA (VFL = VDD –42 V) - Grid driver (COM1 to COM16) : –30 mA (VFL = VDD –42 V) • General output port output current - Output driver (P1 and P2) : ±1 mA (VDD = 3.
3 V ±10%) ±2 mA (VDD = 5.
0 V ±10%) • Content of display - CGROM 5 × 7 dots : 248 types (character data) - CGRAM 5 × 7 dots : 8 types (character data) - ADRAM 16 (display digit) × 2 bits (symbol data) - DCRAM 16 (display digit) × 8 bits (register for character data display) - General output port 2 bits (static operation) • Display control function - Display digit : 9 to 16 digits - Display duty (contrast adjustment) : 8 stages - All lights ON/OFFs • 3 interfaces with microcontroller : DA, CS, CP (4 interfaces when RESET is added) • 1-byte instruction execution (excluding data write to RAM) • Built-in oscillation circuit (external R and C) • Package options: 64-pin plastic QFP (QFP64-P-1414-0.
