M37273E8SP, M37273EFSP

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 M37273M8-XXXSP and M37273MF-XXXSP are single-chip mi-

(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

crocomputers 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 M37273E8SP and M37273EFSP are similar to

those of the M37273M8-XXXSP and M37273MF-XXXSP except that

the chip has a built-in PROM which can be written electrically. The

difference between M37273M8-XXXSP and M37273MF-XXXSP are

the ROM size and RAM size. Accordingly, the following descriptions

will be for the M37273M8-XXXSP.

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 .............. 32K bytes

Window function

(M37273M8-XXXSP, M37273E8SP)

60K bytes

3. APPLICATION

TV with a closed caption decoder

(M37273MF-XXXSP, M37273EFSP)

RAM ............... 1152 bytes

(M37273M8-XXXSP, M37273E8SP)

1472 bytes

(M37273MF-XXXSP, M37273EFSP)

(*ROM correction memory included)

●Minimum instruction execution time

......................................... 0.5 µs (at 8 MHz oscillation frequency)

●Power source voltage ................................................. 5 V ± 10 %

●Subroutine nesting ............................................. 128 levels (Max.)

●Interrupts ....................................................... 17 types, 16 vectors

●8-bit timers .................................................................................. 6

●Programmable I/O ports (Ports P0, P1, P2, P30, P31) ............. 26

●Input ports (Ports P50, P51) ........................................................ 2

●Output ports (Ports P52–P57,P6) .............................................. 14

●12 V withstand ports ................................................................... 6

●LED drive ports ........................................................................... 4

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

●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
