1.0 GENERAL DESCRIPTION
The CompactFlash card contains a controller, embedded
firmware storage and flash media in a matchbook-sized
package with a 50-pin connector consisting of two rows of
25 female contacts each on 50 mil (1.27 mm) centers.
Refer to Figure 1-1 for the CompactFlash card block dia-
gram. The controller interfaces with the host system allow-
ing data to be written to and read from the flash media.
1.1 Performance-optimized ATA Controller
The heart of a CompactFlash card is the ATA controller
which translates standard IDE/ATA signals into flash media
data and controls. SST’s CompactFlash card contains a
proprietary ATA controller that was specifically designed to
attain high data throughput from host to flash. The following
components contribute to the ATA controller’s performance.
1.1.1 Microcontroller Unit (MCU)
The MCU translates IDE/ATA commands into data and
control signals required for flash memory operation.
1.1.2 Internal Direct Memory Access (DMA) Control
The ATA controller inside SST’s CompactFlash card uses
DMA allowing instant data transfer to memory. This imple-
mentation eliminates controller overhead associated with
traditional, firmware-based, memory control, increasing the
data transfer rate.
1.1.3 Power Management Unit (PMU)
The Power Management Unit controls the power consump-
tion of the CompactFlash card. The PMU dramatically
extends product battery life by putting the part of the cir-
cuitry that is not in operation into sleep mode.
1.1.4 SRAM Buffer
A key contributor to the ATA controller performance is a
SRAM buffer. The buffer optimizes the host’s data writes to
the flash media.
1.1.5 Embedded Flash File System
The Embedded Flash File System is an integral part of the
ATM controller. It contains MCU firmware that performs the
following tasks:
1. Translates host side signals into Writes and
Reads to the flash media
2. Provides flash media wear leveling to spread the
flash writes across all the memory address space
to increase the longevity of flash media
3. Keeps track of data file structures
1.1.6 Error Correction Code (ECC)
The ATA Controller contains an ECC algorithm that cor-
rects 3 bytes of error per 512-Byte sector.
