Introduction of EEPROMs for SSDs (VPD)

Serial Presence Detect EEPROM

ABLIC provides Vital Product Data (VPD) EEPROMs for Solid State Drives (SSDs).
Our product line includes the VPD EEPROMs with built-in temperature sensors and/or Address Resolution Protocol (ARP) function that are suitable for data centers, servers and high-end PCs. Our VPD EEPROMs will assist the development of any type of SSD.

 
 

1. Built-in temperature sensor (S-585AA / S-34TS04L)

The built-in temperature sensor in ABLIC’s VPD EEPROMs promotes performance improvements in SSDs used for data centers, servers and other high-end PCs.

2. Support for SMBus ARP (Address Resolution Protocol) function (S-585AA)

The S-585AA supports the SMBus ARP function.
As this IC also supports the SMBus ARA function*1 and timeout function*2 and is therefore ideal for use with SSDs that communicate over the SMBus.

SMBus ARP functionWhat is an ARP (Address Resolution Protocol) function?

The ARP is a function that allows a HOST to arbitrarily assign an address to slave devices.
Therefore, easy to add SSDs.
*This function complies with the SMBus rev. 3.1 standard.

 

*1 ARA (Alert Response Address) function:
A function for easily detecting which slave device set the EVENT pin to Lo (assert)
*2 Timeout function:
A function that resets the communications and set the device to standby mode when the SCL pin stays “L” for the certain time period (tTIMEOUT.MAX) or more

3. Low voltage operation: 1.7V min.

The EEPROM’s low-voltage operation (operation voltage range: 1.7V – 3.6V) of 1.7V min. means it can be used with 1.8V AUX power supplies.

Low voltage operation: 1.7V min.
