This IC is a DDR5 Serial Presence Detect EEPROM with Hub function (SPD5 Hub) built in temperature sensor.
The Hub feature allows isolation of a local bus from a controller host bus. This IC contains 1024 bytes (8K-bit) of EEPROM arranged as 16 blocks of 64 bytes (512 bit) per block. Each block can be write protected via software command. Page write and sequential read are available. This IC operates with 1.8 V VDDSPD and 1.0 V VDDIO and the SidebandBus (I2C & I3C) at 12.5 MHz maximum.
Caution
This product is intended to use in general electronic devices such as consumer electronics, office equipment, and communications devices. Before using the product in medical equipment or automobile equipment including car audio, keyless entry and engine control unit, contact to ABLIC Inc. is indispensable.

Hub Function
- Interfaces to I2C/I3C buses which have multiple devices on a shared bus
- Uniquely addressed with fixed addressing on the same bus.
- All Hubs respond to specific predefined I2C/I3C device select codes on a host interface bus
- Integrates a second local I2C/I3C bus and passes through of commands from host bus onto local bus for addressing of I2C/I3C devices on local bus
