S71125-03-000 9/01 375 1.0 GENERAL DESCRIPTION The SST’s CompactFlash card contains a controller, embedded firmware storage and flash media in a match- book 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 for SST’s CompactFlash card block diagram. The controller interfaces with the host sys- tem allowing 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 data transfer rate. 1.1.3 Power Management Unit (PMU) Power Management Unit controls the power consumption of the CompactFlash card. The PMU dramatically extends product battery life by putting the part of the circuitry 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 host’s data writes to flash media. 1.1.5 Embedded Flash File System Embedded Flash File System is an integral part of the SST’s ATM controller. It contains MCU firmware that per- forms the following tasks: 1. Translates host side signals into flash media Writes and Reads. 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 ECC algorithm that corrects 3 bytes of error per 512 Byte sector.
