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

and ON-SCREEN DISPLAY CONTROLLER

OSD function

DESCRIPTION

•

The M37271MF-XXXSP is a single-chip microcomputer designed with

CMOS silicon gate technology. It is housed in a 52-pin shrink plastic

molded DIP.

Display characters ...............................40 characters ✕ 16 lines

Kinds of characters ..................................................... 320 kinds

(In EXOSD mode, they can be combined with 32 kinds of extra

fonts)

In addition to their simple instruction sets, the ROM, RAM and I/O

addresses are placed on the same memory map to enable easy pro-

gramming.

Dot structure ........................................ CC mode : 16 ✕ 26 dots

OSD mode : 16 ✕ 20 dots

The M37271MF-XXXSP has a OSD function and a data slicer func-

tion, so it is useful for a channel selection system for TV with a closed

caption decoder. The features of the M37271EF-XXXSP and the

M37271EFSP are similar to those of the M37271MF-XXXSP except

that these chips have a built-in PROM which can be written electri-

cally.

EXOSD mode : 16 ✕ 26 dots

Kinds of character sizes................................ CC mode : 2 types

OSD mode : 14 types

EXOSD mode : 6 types

It can be specified by a character unit (maximum 7 kinds).

Character font coloring, character background coloring

It can be specified by a screen unit (maximum 7 kinds).

Extra font coloring, raster coloring, border coloring

Kinds of character colors ............... CC mode : 7 kinds (R, G, B)

OSD mode : 15 kinds (R, G, B, I)

FEATURES

•

APPLICATION

TV with a closed caption decoder

Output ports (Ports P52–P55) ...................................................... 4

•

12 V withstand ports ..................................................................11

•

LED drive ports ........................................................................... 2

•

Serial I/O ............................................................ 8-bit ✕ 1 channel

•

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

•

A-D converter (8-bit resolution) ................................... 4 channels

•

PWM output circuit........................................................... 8-bit ✕ 7

•

Interrupt interval determination circuit ......................................... 1

•

Power dissipation

•

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

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

slicer on)

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

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