Unspecified 

MC3401A/3411A

DESCRIPTION

MC3401A/3411A is a Vacuum Fluorescent Display (VFD) Controller driven on a 1/4 to 1/12 duty factor.

Sixteen segment output lines, 4 grid output lines, 8 segment/grid output drive lines, one display memory,

control circuit, key scan circuit are all incorporated into a single chip to build a highly reliable peripheral

device for a single chip micro computer.

Serial data is fed to MC3401A/3411A via a three-line serial interface.

MC3401A is housed in a 44-pin LQFP

MC3411A is housed in a 48-pin QFN
