APXXXXSDXXX/APXXXXSDHCX
PRODUCT DESCRIPTION
Apacer SD2.0 Memory Card is designed specifically for SD2.0 Card applications that put a premium on
small form factor with lower power. All device and interface configuration data are (such as maximum
frequency, card identification, etc.) stored on the card. For compatibility with existing controllers, the
SD2.0 memory Card offers, in addition to the SD2.0 card interface, an alternate communication protocol
that is based on the SPI standard.
The SD2.0 Memory Card includes an intelligent controller that manages interfaced protocols and data
storage and retrieval as well as Error Correction Code (ECC) algorithms, defect handling and
diagnostics, power management and Content Protection for Recordable Media related functions.
The SD2.0 Card is data storage Memory Card. It is integrated with controller & NAND type Flash
memory with serial & random access capability. The device is designed for cameras, smart phones,
digital recorders, MP3 players, PDAs, electronic toys, etc. The Apacer SD2.0 card meets SDA (SD card
Association) Specifications. This document gives a general overview of the SD2.0 Memory Card
architecture. A detailed description can be found in “SDA Specifications “.
The SD2.0 Memory Card is a memory card that is specifically designed to meet the security, capacity,
performance and environment requirements inherent in newly emerging audio and video consumer
electronic devices. The SD2.0 Memory Card will include a copyright protection mechanism that complies
with the security of the SDMI standard and will be faster and capable for higher Memory capacity. The
SD2.0 Memory Card security system uses mutual authentication and a "new cipher algorithm" to protect
from illegal usage of the card content. A none secured access to the user‘s own content is also available.
The physical form factor, pin assignment and data transfer protocol are forward compatible with the
Multimedia Card with some additions.
The SD2.0 Memory Card communication is based on an advanced 9-pin interface (Clock, Command,
4xData and 3xPower lines) designed to operate in at maximum operating frequency of 50MHz of and
low voltage range.
