ATP A750Pi and A650Si/Sc Embedded 3D TLC Up to 1,920GB SSDs Match MLC Endurance With “66% Higher Endurance” Than Other 3D TLC Drives

ATP Electronics, Inc. introduces the A750Pi and A650Si/Sc Series embedded SSDs built on 3D TLC NAND flash.

Manufactured using a new die package, the SATA SSDs deliver 66% higher endurance in native TLC mode and 50% higher in pseudo single level cell (pSLC) mode, making them on par with drives built on MLC and SLC flash, respectively.

This SSDs come in M.2 2280 and 2242 as well as 2.5” and mSATA form factors. A750Pi/A650Si SSDs support industrial temperature (I-Temp) ranges from -40°C to 85°C to perform reliably even when operating under extreme and harsh conditions. A650Sc SSDs can support commercial operating temperatures (C-Temp) from 0°C to 70°C.

A650Si/Sc with native TLC NAND flash have capacities from 120 to 1,920GB, while A750Pi drives configured in pSLC offer 80 to 640GB. Depending on project and specific part number request, firm’s SATA embedded SSDs are also available as SEDs featuring AES-256 encryption and Opal TCG 2.0-compliant security.

“Industries were initially hesitant to use TLC for applications that required reliable performance and long endurance. Conscious of TLC limitations, ATP worked hard to make it equivalent to, or even better than its pricier MLC and SLC counterparts, minus the hefty cost of ownership,” said Chris Lien, head, embedded SSD business unit. “As an industry leader, we did not rest until we have exhausted all possible means and resources to deliver these premium offerings. We are proud to say that our 3D TLC products are exceptionally competitive, thanks to a new die package design, exhaustive testing and validation, superior power loss protection, and other features. ATP’s advanced pSLC technology extends the general endurance to more than 10 times that of TLC-based products. It also improves the sustained write performance and reliability of the drive, making the drives suitable for write-intensive applications.”

Reliability testing and validation: Setting ATP SSDs cut above the rest
Reliability testing is a cornerstone in the company’s manufacturing process. The firm’s embedded SATA SSDs go through standard as well as customizable testing depending on customer requests and application-specific requirements.

• • Four-corner, temperature cycling, and power cycling tests demonstrate that the SSDs can still perform reliably and are able to handle stored data without data miscompare even under harsh conditions.

  • End-of-life validation test makes sure that the company’s SSDs perform reliably and maintain data integrity over their life span (and even beyond) as required.

  • PCBA solderability validation makes sure that components on the printed circuit board assembly are effectively bonded to form reliable mechanical and electrical connections.

  • Reliability Demonstration Test validates the MTBF rating of the drive through actual drive-level testing instead of relying on reliability prediction systems.

Breakthrough MCU design for enhanced power management and PLP capabilitiesThe A750Pi/A650Si Series SATA SSDs feature a design of the power loss protection (PLP) array, which utilizes a new power management IC (PMIC) and new firmware-programmable MCU (microcontroller unit). The MCU design allows the PLP array to perform intelligently in various temperatures, power glitches and charge states. The following table summarizes the features and benefits of the new MCU-based design:

ATP SSD configuration tool

The company’s SSD Configuration Tool is available to make sure that the firm’s storage solutions meet customers’ requirements. Customers simply need to input their desired specifications, such as form factor, capacity, operating temperature, and endurance (in terabytes written or TBW). They also have the option to configure based on a 2-year or 5-year workload. The tool can help assess if a standard product is available for purchase, or if customization is required.
