1.0 GENERAL DESCRIPTION
The CompactFlash card controller contains a microcontrol-
ler and embedded flash file system integrated in TQFP or
TFBGA packages. Refer to Figure 2-1 for the Compact-
Flash card controller block diagram. The controller inter-
faces with the host system allowing data to be written to
and read from the flash media.
1.1 Performance-optimized CompactFlash
Card Controller
The heart of the CompactFlash card is the CompactFlash
card controller which translates standard CF signals into
flash media data and control signals. The following compo-
nents contribute to the CompactFlash card controller’s
operation.
1.1.1 Microcontroller Unit (MCU)
The MCU translates CF commands into data and control
signals required for flash media operation.
1.1.2 Internal Direct Memory Access (DMA)
The CompactFlash card controller uses internal DMA
allowing instant data transfer from buffer to flash media.
This implementation eliminates microcontroller overhead
associated with the traditional, firmware-based approach,
thereby 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 controller. The PMU dramat-
ically
reduces
the
power
consumption
of
the
CompactFlash card controller 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 CompactFlash card controller per-
formance is an SRAM buffer. The buffer optimizes the
host’s data transfer to and from the flash media.
1.1.5 Embedded Flash File System
The embedded flash file system is an integral part of the
CompactFlash card controller. It contains MCU firmware
that performs the following tasks:
1. Translates host side signals into flash media
writes and reads.
2. Provides dynamic flash media wear leveling to
spread the flash writes across all unused 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 CompactFlash card controller utilizes 72-bit Reed-
Solomon Error Detection Code (EDC) and Error Correc-
tion Code (ECC), which provides the following error
immunity for each 512-byte block of data:
1. Corrects up to three random 12-bit symbol errors.
2. Corrects single bursts up to 25 bits.
3. Detects single bursts up to 61 bits and double
bursts up to 15 bits.
4. Detects up to six random 12-bit symbol errors.
1.1.7 Serial Communication Interface (SCI)
The Serial Communication Interface (SCI) is designed to
report initialization errors and allow manufacturers to debug
system failures.
1.1.8 Multi-tasking Interface
The multi-tasking interface enables fast, sustained write
performance by allowing concurrent Read, Program, and
Erase operations to multiple flash media devices. This
interface optimizes the performance of Multi-Level Cell
(MLC) and high density Single-Level Cell (SLC) flash
media.
