1. General Description
Apacer’s value-added Industrial CompactFlash Card offers high performance, high reliability and power-
efficient storage. Regarding standard compliance, this CompactFlash Card complies with CompactFlash
specification revision 4.1, supporting transfer modes up to Programmed Input Output (PIO) Mode 6, Multi-
word Direct Memory Access (DMA) Mode 4, Ultra DMA Mode 6, and PCMCIA Ultra DMA Mode 6.
For power efficiency, this industrial CompactFlash card supports some power smart design mechanisms
such as Power-On-Reset, voltage regulator for output voltage adjustments and power failure protection,
as well as the automatic sleep and wake-up feature. In terms of security, it comes with a hardware write
protect switch.
Apacer’s value-added CFC provides complete PCMCIA - ATA functionality and compatibility. Apacer ‘s
CompactFlash technology is designed for applications in Point of Sale (POS) terminals, telecom, IP-STB,
medical instruments, surveillance systems, industrial PCs and handheld applications such as the new
generation of Digital Single Lens Reflex (DSLR) cameras.
1.1 Performance-Optimized Controller
The CompactFlash Card Controller translates standard CF signals into flash media data and control
signals.
1.1.1 Power Management Unit (PMU)
The power management unit (PMU) controls the power consumption of the CompactFlash card controller.
It reduces the power consumption of the CompactFlash Card Controller by putting circuitry not in
operation into sleep mode. The PMU has zero wake-up latency.
1.1.2 SRAM Buffer
The CompactFlash Card Controller performs as an SRAM buffer to optimize the host’s data transfer to
and from the flash media.
1.1.3 Embedded Flash File System
The embedded Flash File System (FFS) is an integral part of the CompactFlash controller. It contains the
MCU firmware to perform the following tasks:
1. Translate host side signals into flash media writes and reads
2. Provide dynamic data flash media wear leveling to spread the flash writes across all unused
memory address space to increase the longevity of flash media
3. Keep track of data file structures
1.1.4 Error Correction Code (ECC)
The CompactFlash card is programmed with BCH Error Detection Code (EDC) and Error Correction Code
(ECC) algorithms capable of correcting up to 24 random bits in 1,024 bytes data.
High performance is achieved through hardware-based error detection and correction.
