DFN-8(2030)B (PQ008-B)

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 V_DDSPD and 1.0 V V_DDIO 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.

Parts List

U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
These descriptions may be different from the actual product name and parameter.
