The SH7239 Series is a high-end single chip microcontroller incorporating an SH-2A core that offers a maximum operating frequency of 160MHz. The SH7239 Series lineup consists of the SH7239 group (with floating-point unit (FPU)) and the SH7237 group (without FPU).

The SH7237/SH7239 group incorporates various peripheral function suitable for industrial application AC servos, general-purpose inverters and robots, such as a 16-bit multifunction timer unit(MTU2/MTU2S) and a 12-bit A/D converter, etc.  In comparison with a conventional product, maximum operating frequency of MTU2 was improved. (3.3V version: max 80MHz, 5V version: max 100MHz)

The SH7237/SH7239 group incorporates 512KB flash memory and 64KB RAM in addition to 32KB flash memory for data storage.

The SH7237/SH7239 group also incorporates various interfaces such as a CAN, 4 channel Serial interface, RSPI etc.

The SH7237/SH7239 group realizes a single power supply. The lineup consist of 3.3V version (maximum operating frequency : 160MHz) and 5V version (maximum operating frequency : 100MHz). (Analog power supply is 5V)
