To all our customers
Regarding the change of names mentioned in the document, such as Mitsubishi
Electric and Mitsubishi XX, to Renesas Technology Corp.
The semiconductor operations of Hitachi and Mitsubishi Electric were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi
Semiconductors, and other Mitsubishi brand names are mentioned in the document, these names
have in fact all been changed to Renesas Technology Corp. Thank you for your understanding.
Except for our corporate trademark, logo and corporate statement, no changes whatsoever have been
made to the contents of the document, and these changes do not constitute any alteration to the
contents of the document itself.
Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices
and power devices.

MITSUBISHI MICROCOMPUTERS
M37151M6/M8/MA/MC/MF-XXXFP, M37151EFFP
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
1. DESCRIPTION
The M37151M6/M8/MA/MC/MF-XXXFP and M37151EFFP are
single-chip microcomputers designed with CMOS silicon gate tech-
nology. They have an OSD, data slicer, and I2C-BUS interface, mak-
ing them perfect for TV channel selection systems with a closed cap-
tion decoder. The M37151EFFP has a built-in PROM that can be
written electrically.
