M37272M6/M8–XXXSP/FP, M37272MA–XXXSP

M37272E8SP/FP, M37272EFSP

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

and ON-SCREEN DISPLAY CONTROLLER

1. DESCRIPTION

●OSD function

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

The M37272M6/M8-XXXSP/FP and M37272MA-XXXSP are single-

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

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

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

OSD mode: 16 ✕ 20 dots

chip microcomputers designed with CMOS silicon gate technology.

They have a OSD, data slicer, and I C-BUS interface, so it is useful

for a channel selection system for TV with a closed caption decoder.

The features of the M37272E8SP/FP and M37272EFSP are similar

to those of the M37272M6-XXXSP except that the chip has a built-in

PROM which can be written electrically. The difference between

M37272M6-XXXSP/FP, M37272M8-XXXSP/FP and M37272MA-

XXXSP are the ROM size and RAM size. Accordingly, the following

descriptions will be for the M37272M6-XXXSP/FP.

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

OSD mode: 8 kinds

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

Coloring unit ................... character, character background, raster

Display position

Horizontal: 128 levels

Vertical: 512 levels

Attribute ........................................................................................

2. FEATURES

CC mode: smooth italic, underline, flash, automatic solid space

●Number of basic instructions .................................................... 71

OSD mode: border

Smoth roll-up

●Memory size

ROM .............. 24K bytes

●Multi-master I C-BUS interface .............................. 1 (2 systems)

●A-D comparator (6-bit resolution) ................................ 6 channels

●PWM output circuit......................................................... 8-bit ✕ 6

●Power dissipation

In high-speed mode ......................................................... 165 mW

(at VCC = 5.5V, 8 MHz oscillation frequency, OSD on, and Data

slicer on)

In low-speed mode ......................................................... 0.33 mW

(at VCC = 5.5V, 32 kHz oscillation frequency)

●ROM correction function ................................................ 2 vectors

●Closed caption data slicer
