The Product Has a Slightly Unique and Interesting Personality

For the engines used for agricultural machines, construction machines, industrial machines, railway, etc., high-speed and high-accuracy control by microcontrollers is required even under a strict environment of low and high temperatures to enhance fuel consumption and reduce CO₂ emission.

The microcontroller introduced here incorporates a higher CPU performance, larger memory space, wider temperature range, and peripheral functions optimum for the applications, and best suited to the utility engines.

• High-performance RH850/E1x series and SH7250 series incorporate the floating-point operation unit for the engine control
• SH72Ax series fully utilizes the performance of the motors and provides the high-efficient and optimum control
• Automotive microcontroller V850E2/Fx4-L boasts the enriched package products

Features

Wider temperature range

• Ta = -40 °C to +125 °C, available for industrial use in tough conditions

On-chip large-capacity Flash

• Maximum RH850/E1M-S: 4MB

Built-in CAN controller

• Supports the highly-reliable interunit communication

Enhanced safety function

• Actions against a software error → The memory incorporates ECC, and the package is made of low-alpha resin
• Incorporates CRC/MISG (used for the CPU self-diagnosis)
• Adds the self-diagnosis function to the A/D converter
• Incorporates MPU (memory protection circuit) (RH850/E1x, SH72Ax)
• Conforms to the functional safety standard ISO 26262 (RH850/E1x)

Long-period supply

• This product adopts the cutting-edge 90nm process, and the stable supply for 10 years or longer is secured
• The 90nm process is adopted for SH725x, SH72Ax, V850E2/Fx4-L, and Px4-L, and the stable supply for about 10 years is secured
