The NCA95118 is a device compatible with JEDEC standard JESD300-5B. The SPD5 Hub device contains 1024 bytes of NVM (non-volatile memory) arranged as 16 blocks of 64 bytes per block. Each block may optionally be write-protected via software command. Write protection for each block may be overridden in an offline programmer environment while overrides are prevented in normal use. The SPD5 Hub device operates from 1.8V nominal power supply input. The SPD5 Hub device is intended to operate up to 12.5MHz on a 1.0V I3C basic bus or up to 1MHz on a 1.0V to 3.3V I2C bus. The SPD5 Hub device is intended to interface to I2C/I3C basic buses which have multiple devices on a shared bus and must be uniquely addressed with fixed addressing on the same bus. The SPD5 Hub device incorporates thermal sensing capability which is controlled and read over I2C/I3C basic bus.
