4 1. General Description Apacer s SATA-Disk Module (SDM) is a high-performance, embedded flash drive designed to replace the conventional hard disk drive. The SDM I can be plugged into a standard Serial ATA connector commonly found in desktops, portables and industrial PCs. Apacer s SDM includes a built-in microcontroller with file management firmware that communicates through the Serial ATA standard interface. This product is well suited for embedded flash storage applications offering new and expanded functionalities, as well as more cost-effective designs, better performance and increased reliability. The SDMs are designed to work at 5 Volts, support the standard Serial ATA protocol and use the standard Serial ATA driver for all major operating systems. Each SDM comes with a factory-programmed, 20-byte long ID number that protects data from unauthorized duplication. The ID number can be used as an encryption key. In general, the SATA-Disk Module contains SATA and Flash Management controller, embedded firmware, and the flash media with Serial ATA connector. While interfacing with the host system, it allows data to be written to and read from the flash media. 1.1 Performance-Optimized Controller The heart of an SDM is the SATA controller, which translates standard SATA signals into the data and controls of the flash media. The SATA and Flash Management controller are specifically designed to attain high data throughput from the host to the flash Power Management Unit (PMU) The power management unit (PMU) controls the power consumption of the SDM. It can dramatically extend product battery life by leaving the idle part of the circuitry into sleep mode. The PMU has zero wake-up latency SRAM Buffer The SRAM buffer is a key contributor to the SATA and Flash Management controller performance. It optimizes data writes to the flash Embedded Flash File System The embedded Flash File System (FFS) is an integral part of the SATA and Flash Management controllers. 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 Error Correction Code (ECC) The SDM uses BCH Error Detection Code (EDC) and Error Correction Code (ECC) algorithms which correct up to eight random single-bit errors for each 512-byte block of data. High performance is achieved through hardware-based error detection and correction. 4
