MITSUBISHI IC’S
M35501FP
FLD (VFD) DIGIT EXPANDER
DESCRIPTION
The M35501FP generates digit signals for fluorescent display
when connected to the output port of a microcomputer. There are
up to 16 digit pins available, and more can be added by connect-
ing additional M35501FPs. The number of fluorescent displays
can be increased easily by connecting the M35501FP to the
CMOS FLD (VFD; Vacuum Fluorescent Display) output pins of an
8-bit microcomputer in MITSUBISHI’s 38B5 Group. The
M35501FP is suitable for fluorescent display control on household
electric appliances, audio products, etc.
