GENERAL DESCRIPTION

The MSC7170-01 is a display controller/segment driver containing a 5 x 6 keyscan circuit, designed for a 5 x 7 dot matrix type vacuum fluorescent (VF) display tube.

Use of the MSC1164 grid driver allows a maximum of 16-digit pair to be displayed, or use of the MSC7171 grid driver allows a maximum of 12 digit pairs to be displayed.

FEATURES

• Able to display 5 x 7 dot matrix type characters of a maximum of 16 digits x 2 lines (when MSC1164 is used)

• The number of display digits selectable in a range of 1 digit x 2 lines to 16 digits x 2 lines

• Standby function

Combination of the MSC7171 grid driver and the MSC7170-01 decreases grid driver current during the standby mode of the driver.

• Display intensity selectable by 10-bit digital dimming

• Display characters selectable from among 256 types by internal PLA

• 8-bit synchronous serial data transfer SPI interface

• 5 x 6 keyscan circuit

• Driver output current (IOH) : 1 mA (SEG1 to SEG35) : –15 mA (SEG36)

• Supply voltage: VDD = 5 V±10 : VDISP = 60 V (max.)

• Package:

100-pin plastic QFP (QFP100-P-1420-0.65-BK) (Product name: MSC7170-01GS-BK)
