ML9208A-xx

5 ï´ 7 Dot Character ï´ 16-Digit Display Controller/Driver with Character RAM

GENERAL DESCRIPTION

The ML9208A-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

ï· Logic power supply and vacuum fluorescent display tube drive power supply (VDD)

: 3.3 V ï± 0.3V or 5.0 V ï± 0.5V

ï· Fluorescent display tube drive power supply (VFL) : VDD â20 V to VDD â42 V

ï· 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)

- Segment driver (AD1 and AD2)

- Grid driver (COM1 to COM16)

ï· General output port output current

- Output driver (P1 and P2)

ï· Content of display

: ï±1 mA (VDD = 3.3 V ï± 0.3V)

ï±2 mA (VDD = 5.0 V ï± 0.5V)

- CGROM 5 ï´ 7 dots

: 248 types (character data)

- CGRAM 5 ï´ 7 dots

: 8 types (character data)

- ADRAM 16 (display digit) ï´ 2 bits (symbol data)

- DCRAM 16 (display digit) ï´ 8 bits (register for character data display)

- General output port

2 bits (static operation)

ï· Display control function

- Display digit

: 9 to 16 digits

- Display duty (contrast adjustment)

: 16 stages

- All lights ON/OFFs

ï· 3 interfaces with microcontroller

: DA, CS, CP (4 interfaces when RESET is added)

ï· 1-byte instruction execution (excluding data write to RAM)

ï· Built-in oscillation circuit (external R and C)

ï· Package options:
