1. DESCRIPTION
The M37161M8/MA/MF-XXXSP/FP and M37161EFSP/FP are single-
chip microcomputers designed with CMOS silicon gate technology.
They have an OSD and I
2
C-BUS interface, making them perfect for
a channel selection system for TV.
The M37161EFSP/FP has a built-in PROM that can be written elec-
trically.
