Description

The M37212M6-XXXSP/FP, M37212M4 / M8-XXXSP are single-chip microcomputers designed with CMOS silicon gate technology. They have a OSD, I2C-BUS interface, and PWM, so it is useful for a channel 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 descriptions will be for M37212M6-XXXSP/FP unless otherwise noted.

1. Number of basic instructions : 71

2. Interrupts : 4 types, 14 vectors

3. 8-bit timers : 4

4. 12 V withstand ports : 12

5. LED drive ports : 4

6. Serial I/O : 8-bit 5 1 channel
