1. General Description
As the demand of reliable and high-performance data storage in a small form factor increases, Apacer’s
embedded SD card is designed specifically for rigorous applications by offering maximum endurance,
reliability, and agility, where extreme traceability, enhanced data integrity, and exceptionally velocity are
required.
1.1 Product Function Block
The embedded SD contains a flash controller and flash media with SD standard interface.
1.2 Functional description
The embedded SD device contains a high level, intelligent subsystem that provides many capabilities
including:
Powerful ECC algorithms
Global wear-leveling algorithms
Power management for low power operation
SD Interface

1.2.1 Flash Management
The SD controller contains logic/physical flash block mapping and bad block management system. It will
manage all flash block include user data space and spare block.
The embedded SD also contains a sophisticated defect and error management system. It does a read
after write under margin conditions to verify that the data is written correctly (except in the case of write
pre-erased sectors). In case that a bit is found to be defective, the embedded SD replaces this bad bit
with a spare bit within the sector header. If necessary, the embedded SD will even replace the entire
sector with a spare sector. This is completely transparent to the master (host device) and does not
consume any user data space.
1.2.2 Powerful ECC Algorithms
The powerful ECC algorithms will enhance flash block use rate and whole device life. The SD controller
has an innovative algorithm to recover the data. Built-in BCH-ECC supports correction up to 24 bits data
error per 1K bytes data automatically
1.2.3 Power Management
A power saving feature of the embedded SD is automatic entrance and exit from sleep mode. Upon
completion of an operation, the embedded SD will enter the sleep mode to conserve power if no further
commands are received within X seconds, where X is programmable by software. The master does not
have to take any action for this to occur. The embedded SD is in sleep mode except when the host is
accessing it, thus conserving power.
Any command issued by the master to the embedded SD will cause it to exit sleep mode and response to
the master.
