ROHM BU1850MUV handbook
The GPIO Expander IC BU1850MUV is a chip used to expand IO ports. It can control GPIO output states through the I2C write protocol and read GPIO input states through the I2C read protocol. Furthermore, it has an interrupt function that can release the CPU from polling the registers in the GPIO expander. GPIO expanders are also equipped with built-in power on reset, 3V tolerant input, and NMOS open-drain output.

ROHM BU1851GUW handbook
The BU1851GUW key encoder IC is an 8x8 keyboard encoder IC that supports 64 keys and is compatible with QWERTY keyboards. It adopts the architecture that the information of the only key whose status is changed, such as push or release, is encoded into the 8 bits data. This can greatly reduce the CPU load which tends to become heavier as the number of keys increase. (Previously, all key's status is stored in the registers.) Furthermore, auto sleep function contribute to low power consumption, when no keys are pressed. It is also equipped with the various functions such as ghost key rejection, N-key Rollover, Built-in power on reset and oscillator.
