This manual provides information on the hardware structure, pin configuration, peripheral circuits and application design of H8S/2378 and H8S/2378R microcontrollers.
This hardware manual describes the H8S/2378 and H8S/2378R group microcontrollers. It covers the CPU core, on‑chip peripherals such as DMA controllers, timers, serial interfaces, A/D and D/A converters, and optional I²C interfaces, as well as package options and pin configurations.
The document also includes safety precautions, handling notes, a list of registers, electrical characteristics, revision history, and an index to help designers integrate the device into their applications.
| CPU internal configuration | 32‑bit |
|---|---|
| General registers | Sixteen 16‑bit registers |
| Address space | 16‑Mbyte linear |
| A/D converter | 10‑bit |
| D/A converter | 8‑bit |
| Number of I/O pins | 96 VO pins, 17 input‑only pins |
| Flash memory version | F‑ZTAT™ single‑power flash |
No, the NC (not connected) pins must not have anything connected to them.
All unused input pins should be fixed to a high or low level to prevent noise‑induced malfunction.
Reset the LSI immediately after the power supply has been turned on.
