M37753FFCFP
M37753FFCHP
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION
DESCRIPTION
The M37753FFCFP and the M37753FFCHP are single-chip micro-
computers designed with high-performance CMOS silicon gate tech-
nology, including the internal flash memory. These are housed in
80-pin plastic molded QFP.
These microcomputers have a CPU and a bus interface unit. The
CPU is a 16-bit parallel processor that can also be switched to per-
form 8-bit parallel processing, and the bus interface unit enhances
the memory access efficiency to execute instructions fast.
In addition to the 7700 Family basic instructions, the M37753FFCFP
and the M37753FFCHP have 6 special instructions which contain in-
structions for signed multiplication/division; these added instructions
improve the servo arithmetic performance to control hard disk drives
and so on.
These microcomputers also include the flash memory, RAM, mul-
tiple-function timers, motor control function, serial I/O, A-D converter,
D-A converter, and so on.
The internal flash memory can be programed and erased by using a
PROM programmer or by control of the central processing unit
(CPU). Therefore, these microcomputers can change the program
easily even after they are mounted on the board.
APPLICATION
Control devices for personal computer peripheral equipment such as
CD-ROM drives, hard disk drives, high density FDD, printers
Control devices for office equipment such as copiers and facsimiles
Control devices for industrial equipment such as communication and
measuring instruments
Control devices for equipment required for motor control such as in-
verter air conditioner and general purpose inverter
