M37212EFSP/FP

SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER

with ON-SCREEN DISPLAY CONTROLLER

1. DESCRIPTION

●OSD function

Display characters ................................... 24 characters ✕ 2 lines

The M37212M6-XXXSP/FP, M37212M4/M8-XXXSP are single-chip

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

Kinds of characters ........................................................ 256 kinds

Character display area..............................................12 ✕ 16 dots

Kinds of character sizes..................................................... 3 kinds

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

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

Display position.............................................................................

microcomputers designed with CMOS silicon gate technology. They

have a OSD, I C-BUS interface, and PWM, so it is useful for a chan-

nel selection system for TV.

The feature of the M37212EFSP/FP are similar to those of the

M37212M6-XXXSP/FP except that these chips have a built-in PROM

which can be written electrically. The differences between the

M37212M6-XXXSP/FP and M37212M4/M8-XXXSP are the ROM size

and the RAM size as shown below. Accordingly, the following de-

scriptions will be for M37212M6-XXXSP/FP unless otherwise noted.

Horizontal: 64 levels

Vertical: 128 levels

Attribute .............................................................................. border

3. APPLICATION

2. FEATURES

24K bytes (M37212M6-XXXSP/FP)

32K bytes (M37212M8-XXXSP)

62K bytes (M37212EFSP/FP)

RAM ......................... 320 bytes (M37212M4-XXXSP)

384 bytes (M37212M6-XXXSP/FP)

576 bytes (M37212M8-XXXSP)

1280 bytes (M37212EFSP/FP)

(*ROM correction memory included)

●The minimum instruction execution time

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

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

●Subroutine nesting

maximum 96 levels (M37212M4/M8-XXXSP, M37212M6-XXXSP/FP)

maximum 128 levels (M37212EFSP/FP)

●Interrupts........................................................ 14 types, 14 vectors

●8-bit timers ................................................................................... 4

●Programmable I/O ports

(Ports P0, P10–P14, P2, P30, P31, P40, P41) ............................. 25

●Input ports (Ports P15–P17, P32–P37, P42) ............................... 10

●Output ports (Ports P52–P55, P60–P63)....................................... 8

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

●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) ................................. 8 channels

●PWM output circuit..........................................14-bit ✕ 1, 8-bit ✕ 8

●Power dissipation.............................................................. 165 mW

(at 8 MHz oscillation frequency, VCC=5.5V, at OSD display)

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

Note: Only M37212M8-XXXSP and M37212EFSP/FP have ROM

correction function.
