ATP Electronics: S600Sia 3D TLC Flash-Based A1 Performance Class Up to 256GB SD and microSD Cards

ATP Electronics, Inc. announced the S600Sia, its first 3D TLC flash-based A1 Performance Class SD and microSD cards built for industrial and automotive applications.

The company employs 64-layer 3D NAND technology, which is standing out to become the mainstream of the automotive and industrial market with steady supply for 5 years. By scaling vertically, 3D NAND mitigates reliability concerns that came with planar NAND’s shrinking lithography.

The company’s 3D TLC memory cards did not inherit the strict reliability tests from 2D NAND, but their performance is customized for automotive and industrial demands.

Automotive-level reliability, performance and endurance
The 3D TLC-based S600Sia memory cards undergo endurance, data retention and wide temperature tests from IC to drive level. They are certified according to ISO, JEDEC, automotive-specific standards and temperature-related standards such as AEC-Q100/AECQ-104. Depending on customer requirements, the company can also conduct customized testing, such as compliance for ISO 16750.

Dynamic self-recovery calibration for cross-temperature scenarios
Aside from supporting wide operating temperature ranges from -40°C to 85°C, the firm’s S600Sia SD/microSD cards undergo cross-temperature tests and implement temperature-related variables and mechanisms to enhance drive integrity. Dynamic Self-Recovery Calibration enables the SD/microSD to adapt to various temperature modes through a combination of firmware and hardware solutions.

Own customization capabilities can satisfy market demand for data management
Big data generated by the IoT and the Internet of Vehicles (IoV) is spurring the data boom for the next decade. Whether it’s for ‘Smart Factories or Autonomous Vehicles’, data management is a critical issue. Efficient data transaction and real time analysis require edge devices to deliver faster and steady performance. The company’s 3D TLC SD/microSD cards feature 4KB page management and SLC caching algorithm, which allows 1/2 random access time and low latency compared with traditional solution. These cards can reach Android A1 application performance (SDA spec) and consume less power, making them for small handheld devices with limited battery life.

S600Sia SD/microSD cards come in capacities of up to 256GB, offering significant reductions in cost/GB. They meet increasing storage needs and offer portable convenience for backup, edge computing, event data recording and map navigation with or without Internet connection.

The firm also offers hardware customization according to customers’ request, such as the NAND flash and controller testing pin and the over current protection (OCP) fuse design for protection vs. current overloading or short circuits.
