ABLIC Introduction of EEPROMs for SSDs (VPD)|Chip One Stop - Shop Online for Electronic Components and Semiconductor

ABLIC provides Vital Product Data (VPD) EEPROMs for SSDs (Solid State Drives). ABLIC also provides a lineup of temperature sensors ideal for data centers, servers and high-end PCs, and a lineup of VPDs with SMBus ARP (Address Resolution Protocol) function, which support the development of a wide variety of SSDs.

What is a VPD EEPROM?

VPD is a device designed to store information about PCIe SSD as shown in “Table 1”.

SSD (Solid State Drive) 向けのVPD (Vital Product Data) EEPROM
VPD is a device that connects to the SSD controller and the host via SMBus. Users can write/read information and data via SMBus.VPD EEPROMs are particularly in demand for multi-part PCIe SSDs, where interconnected information is becoming more complex.

ABLIC’s VPD EEPROMs

ABLIC’s VPD EEPROMs support the development of PCIe SSDs for data centers, servers and high-end PCs.
By using ABLIC VPD EEPROMs, the following is possible:

  1. Enhance thermal throttling performance (S-585AA)
    ・Using a built-in ±0.25℃ typ. high-accuracy digital temperature sensor.
  2. Able to add SSDs while power is on (S-585AA)
    ・Using a built-in SMBus ARP (Address Resolution Protocol) function support for Hot-plug* via SMBus.
  3. Can be connected to a low voltage 1.8V AUX power supply (S-585AA, S-34TS04L)
    ・With a 1.7V min low-voltage operation.
*Hot-plug: a mechanism that allows devices to be connected or faulty components to be replaced while the system is operational.

What is SMBus ARP (Address Resolution Protocol) function?

The SMBus ARP is a function that allows a HOST to assign arbitrary addresses to target devices using the SMBus; this allows for easy SSD adding.

Benefits
  1. Able to add SSDs while power is on with Hot-plug
  2. Able to add more than 32 SSDs per Host
  3. Able to remove external multiplexer
