M37272M6H/M8H/MAH/MFH–XXXSP/FP

M37272E8SP/FP, M37272EFSP/FP

SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER

and ON-SCREEN DISPLAY CONTROLLER

1. DESCRIPTION

The M37272M6H/M8H/MAH/MFH-XXXSP/FP are single-chip micro-

Display characters ................................... 32 characters ꢀ 2 lines

(It is possible to display 3 lines or more by software)

computers designed with CMOS silicon gate technology. They have

a OSD, data slicer, and I C-BUS interface, so it is useful for a chan-

Kinds of characters ........................................................ 254 kinds

Character display area ............................ CC mode: 16 ꢀ 26 dots

nel selection system for TV with a closed caption decoder.

The features of the M37272E8SP/FP and M37272EFSP/FP are simi-

lar to those of the M37272M6H-XXXSP/FP except that the chip has

a built-in PROM which can be written electrically. The difference be-

tween M37272M6H/M8H/MAH/MFH-XXXSP/FP are the ROM size

and RAM size. Accordingly, the following descriptions will be for the

M37272M6H-XXXSP/FP.

Kinds of character sizes ..................................... CC mode: 1 kind

OSD mode: 8 kinds

Kinds of character colors .................................. 8 colors (R, G, B)
