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.

SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 3886 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 3886 group is designed for controlling systems that require
analog signal processing and include two serial I/O functions, A-D
converters, D-A converters, system data bus interface function,
watchdog timer, and comparator circuit.
The multi-master I
2
C bus interface can be added by option.
