Overview
The Industrial SD Card (ISD) of the SQFlash is fully compliant to the specification released by SD Card
Association. The Command List supports [Part 1 Physical Layer Specification Ver3.1 Final] definitions. Card
Capacity of Non-secure Area, Secure Area Supports [Part 3 Security Specification Ver3.0 Final] Specifications.
The SQF-ISD is based on 9-pin interface, designed to operate at a maximum operating frequency of 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. Current capacity would be offered from 4GB to 64GB; it’s possible to
reach 2TB in the future with ex-FAT, which is called SDXC (Extended Capacity SD Memory Card).
The SQF-ISD is specifically made for any rigorous environments where devices need to be operated at
extended temperature, and strong data integrity and reliability are demanded. Such environments include both
industrial and automotive applications. The SQF-ISD is the best choice for exceptional reliability, excellent
performance and wide compatibility.

Card Capacity of Non-secure Area, Secure Area Supports [Part 3 Security
Specification Ver3.0 Final] Specifications
Support SD SPI mode
Designed for read-only and read/write cards.
The Command List supports [Part 1 Physical Layer Specification Ver3.01 Final]
definitions
Copyrights Protection Mechanism - Complies with highest security of SDMI standard
CPRM (Content Protection for Recordable Media) of SD Card supported
Support up to 72bits BCH ECC circuits to protect data communication.
Global Wear Leveling support
SQFlash provides advanced Wear Leveling algorithm, which can efficiently spread
out the flash usage through the whole flash media area. Moreover, by
implementing both dynamic and static Wear Leveling algorithms, the life
expectancy of the NAND Flash is greatly improved.
Card removal during read operation will never harm the content
Password Protection of cards (option)
Write Protect feature using mechanical switch
Built-in write protection features (permanent and temporary)
High transmission speed
+4KV/-4KV ESD protection in contact pads
Dimensions: 32mm (L) x 24mm (W) x 2.1mm (H)
Operating voltage range : 2.7-3.6V
