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 5, and PCMCIA Ultra DMA Mode 5.

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.

In terms of data integrity and accuracy, the CompactFlash card is built with on-chip hardware 13/24 bit

BCH ECC engine that can correct up to 24-bit errors per 1,024 byte data. The 13-bit is used for 2KB page

size with 16 bytes spare region per 512 byte data, while the 24-bit ECC is used for flash with 218 or more

bytes, companied with 4KB data. The controller of this CompactFlash card is designed to transfer the host

data through fast DMA engine and utilize the internal memory buffer in a sufficient way, which greatly

minimizes the internal microprocessor’s loading and improves performance efficiency.

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.
