Overview
The SQFlash Micro Secure Digital card (SQF-MSD) is fully compliant to the specification released by SD Card
Association. The Command List supports [Part 1 Physical Layer Specification Ver3.01 Final] definitions. Card
Capacity of Non-secure Area, Secure Area Supports [Part 3 Security Specification Ver3.00 Final] specifications.
The microSD 3.0 card comes with 8-pin interface, designed to operate at a maximum operating frequency of
50MHz or 100MHz. It can alternate communication protocol between the SD mode and SPI mode. It performs data
error detection and correction with very low power consumption. Its capacity could be more than 128MB and up to
64GB.
SQFlash Industrial Micro SD card is one of the most popular cards today based on its high performance, good
reliability and wide compatibility. Not to mention that it’s well adapted for hand-held applications in
semi-industrial/medical markets already.
