Caution: Permanent damage to the chip may result if absolute maximum ratings are exceeded.
Notes: 1. Do not apply the power supply voltage to the VCL pin in 5 V operation models. Connect an external capacitor between this pin and GND.
2. 12 V must not be applied to any pin, as this may cause permanent damage to the device.
3. The operating temperature range for flash memory programming/erasing is 0°C to +75°C.






Description

The H8/300H CPU is a high-speed central processing unit with an internal 32-bit architecture that is upward-compatible with the H8/300H CPU. It has sixteen 16-bit general registers, can address a 16-Mbyte linear address space, and is ideal for realtime control.
