SATA SSDs incorporate sophisticated power-loss protection

ATP Electronics unveils its next-generation A600Si and A600Sc Serial ATA solid state drives (SATA SSDs) featuring a completely new design of the power loss protection (PLP) array, which utilizes a new power management IC (PMIC) and new firmware-programmable MCU (microcontroller unit).

Integrated into its latest PLP technology, ATP PowerProtector 4, the new MCU design allows the PLP array to perform intelligently in various temperatures, power glitches, and charge states.

Key features

• Enhanced device protection
  • Suppression of power-up inrush current according to customer request
  • Input over-voltage protection to prevent damage to the SSD circuitry
• Better data integrity
  • Input power noise de-glitch to prevent incorrect cache flushing caused by false triggers such as noisy or unstable host input voltage.
  • Under-charge/over-charge protection for hold-up power capacitors
• Fast power on/off control cuts the time required from power-off to re-power on the SSD
• Precise control of reset signal generation and power up/down sequences prevents potential issues in the power up/down of the SSD
• Industrial operating temperature support ensures reliable operation in extreme environments from ‑40°C to 85°C. As components perform and react differently in severely cold or hot scenarios, ATP PowerProtector 4 ensures reliable PLP capacitance in all states of cold start, hot temperature workload, and cross temperature.
• RAID support ensures redundancy and fault tolerance to prevent data loss in the event of a drive failure
• End-to-end data protection prevents unauthorized access to data while it is being transferred from one storage device to another.
• Customization options. The new MCU-based design allows PLP capabilities to be tailor-fitted according to unique customer requirements, application-specific needs, or use cases.

The next-generation ATP SATA SSDs with the new MCU-based design include mSATA, 2.5″ SSDs and M.2 2242/2280 modules. Available with I-Temp (A600Si) and C-Temp (A600Sc) support, the SSDs come in the following capacities — M.2 2280: 120 to 960 GB; M.2 2242 and mSATA: 120 to 480 GB; 2.5″: 120 GB to 1.92 TB
