2 / 122 page DESCRIPTION The M37207MF-XXXSP/FP and M37207M8-XXXSP are single-chip microcomputers designed with CMOS silicon gate technology. It is housed in a 64-pin shrink plastic molded DIP or a 80-pin plastic molded QFP. 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. The M37207MF-XXXSP/FP has a PWM function and an OSD func- tion, so it is useful for a channel selection system for TV. The fea- tures of the M37207EFSP/FP are similar to those of the M37207MF- XXXSP/FP except that these chips have a built-in PROM which can be written electrically. The difference between M37207MF-XXXSP/ FP and M37207M8-XXXSP are the ROM size, RAM size, ROM size for display and kinds of character. Accordingly, the following descrip- tions will be for the M37207MF-XXXSP/FP unless otherwise noted. • Multi-master I2C-BUS interface ...............................1 (3 systems) • Power dissipation In high-speed mode ........................................................ 165 mW (at VCC = 5.5 V, 8 MHz oscillation frequency, CRT on) In low-speed mode ......................................................... 0.33 mW (at VCC = 5.5 V, 32 kHz oscillation frequency) • A-D comparator (6-bit resolution) ................................ 8 channels • PWM output circuit ...................................... 14-bit !1, 8-bit !10 • Interrupt interval determination circuit ........................................ 1 • ROM correction function .......................................... 32 bytes ! 2 • CRT display function Number of display characters ............... 24 characters ! 3 lines (16 lines maximum) Kinds of characters .................. 256 kinds (M37207M8-XXXSP) 384 kinds (M37207MF-XXXSP/FP, M37207EFSP/FP) Character display area .......................................... 12 ! 16 dots Kinds of character sizes ................................................. 4 kinds Kinds of character colors (It can be specified by the character) maximum 15 kinds (R, G, B, I) Kinds of character background colors (It can be specified by the character) maximum 7 kinds (R, G, B) 1/2-character unit color specification is possible.
