GENERAL DESCRIPTION
12-Segment ¥ 16-Digit or 16-Segment ¥ 12-Digit Display Controller/Driver
The MSC7110-01/MSC7112-01 is a display controller to display the timer of video tape recorder, channel operation, and other infomaiton by a vaccum fluorescent display tube. Display data is input by serial transfer from microcontroller.
FEATURES
www.DataSheet4U.com
• Provides the interface with a microcontroller by three signal lines. : DATA IN, CLOCK, and LOAD • Driver output can directly be connected to a vaccum fluorescent display tube without a pull-down resistor. • Display is turned on by dynamic drive mode. • The number of display digits are programmable in the range of : 1 to 12 digits (MSC7112-01) 1 to 16 digits (MSC7110-01) • 12-segment driver output : 16 driver outputs (MSC7112-01) 12 driver outputs (MSC7110-01) • The LED drivers can turn on 5 outputs statically. • RAM data can directly be displayed. • The brightness adjustment is programmable and brightness can be adjusted every 1/15 step. • Built-in power-on-reset circuit • The vacuum fluorescent display tube driver outputs high withstand voltage : VDD-VEE=45V (max). • Logic supply voltage : VDD=5V ± 10% • Package options: 42-pin plastic SDIP (SDIP42-P-600-1.778) : (Product name : MSC7112-01SS) 44-pin plastic QFP (QFP44-P-910-0.80-2K) : (Product name : MSC7110-01GS-2K/MSC7112-01GS-2K)
