MITSUBISHI MICROCOMPUTERS
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
M306V2ME-XXXFP
M306V2EEFP
1. DESCRIPTION
The M306V2ME-XXXFP and M306V2EEFP are single-chip microcomputers using the high-performance
silicon gate CMOS process using a M16C/60 Series CPU core and are packaged in a 100-pin plastic
molded QFP. These single-chip microcomputers operate using sophisticated instructions featuring a high
level of instruction efficiency. With 1M bytes of address space, they are capable of executing instructions at
high speed. They also feature a built-in OSD display function and data slicer, making them ideal for control-
ling TV with a closed caption decoder.
The features of the M306V2EEFP are similar to those of the M306V2ME-XXXFP except that this chip has
a built-in PROM which can be written electrically.
