M37906F8CFP

Product Summary

The M37906F8CFP is a single-chip 16-bit microcomputer. It designed with high-performance CMOS silicon gate technology, including the internal flash memory and being packaged in 42-pin plastic molded SSOP or shrink plastic molded DIP. The M37906F8CFP supports the 7900 Series instruction set, which is enhanced and expanded instruction set and are upper-compatible with the 7700/7751 Series instruction set. The CPU of the M37906F8CFP is a 16-bit parallel processor that can also be switched to perform 8-bit parallel processing. Also, the bus interface unit of the M37906F8CFP enhances the memory access efficiency to execute instructions fast. Therefore, the M37906F8CFP is suitable for office, business, and industrial equipment controller that require high-speed processing of large data. Also, the M37906F8CFP is suitable for motor-control equipment since each of them includes the motor control circuit. Applications are (1)Control devices for office equipment such as copiers and facsimiles; (2)Control devices for industrial equipment such as communication and measuring instruments; (3)Control devices for equipment, requiring motor control, such as inverter air conditioners and general-purpose inverters.
