User manual TRANSCEND TS4GCFX500 DATASHEET

[. . . ] TS2G~16GCFX500 Description Transcend CFast cards are designed to satisfy high performance requirements using a SATA 3Gb/s interface. As a removable device, it is easier to plug and remove in space-limited applications; such as CFast Card Features · · · · · · · · RoHS compliant CFast Specification Version 1. 0 Compliant Power Supply: 3. 3V±5% Operating Temperature: 0oC to 70oC Storage Temperature: -40oC to 85oC Humidity (Non condensation): 0% to 95% Built-in 8-bit/512Byte ECC (Error Correction Code) functionality ensures highly reliable of data transfer. Global wear-leveling algorithm eliminate excessive write operation and extends product life. · Suppot StaticDataRefresh & EarlyRetirement technology to monitor error bit level and react before data is corrupted. thin-clients or industrial PCs. [. . . ] Following calibration the device sends a six burst COMWAKE sequence and then sends a continuous stream of the ALIGN sequence starting at the device's highest supported speed. After ALIGNP Dwords have been sent for 54. 6 us (2048 nominal Gen1 Dword times) without a response from the host as determined by detection of ALIGNP primitives received from the host, the device assumes that the host cannot communicate at that speed. If additional speeds are available the device tries the next lower supported speed by sending ALIGNP Dwords at that rate for 54. 6 us (2048 nominal Gen1 Transcend Information Inc. 11 V0. 5 TS2G~16GCFX500 reached without response from the host, the device enters an error state. CFast Card Dword times. ) This step is repeated for as many slower speeds as are supported. Host locks ­ after detecting the COMWAKE, the host starts transmitting D10. 2 characters at its lowest supported rate. Meanwhile, the host receiver locks to the ALIGN sequence and, when ready, returns the ALIGN sequence to the device at the same speed as received. A host shall be designed such that it acquires lock in 54. 6 us (2048 nominal Gen1 Dword times) at any given speed. The host should allow for at least 873. 8 us (32768 nominal Gen1 Dword times) after detecting the release of COMWAKE to receive the first ALIGNP. This ensures interoperability with multi-generational and synchronous designs. If no ALIGNP is received within 873. 8 us (32768 nominal Gen1 Dword times) the host restarts the power-on sequence ­ repeating indefinitely until told to stop by the Application layer. Device locks ­ the device locks to the ALIGN sequence and, when ready, sends SYNCP indicating it is ready to start normal operation.

Device locks ­ the device locks to the ALIGN sequence and, when ready, sends the SYNCP primitive indicating it is ready to start normal operation. Upon receipt of three back-to-back non-ALIGNP primitives, the communication link is established and normal operation may begin.

If there is data in the write cache, that data shall be written to the media. The BSY bit shall remain set to one until all data has been successfully written or an error occurs. IDENTIFY DEVICE (ECh) This commands read out 512Bytes of drive parameter information. Parameter Information consists of the arrangement and value as shown in the following table. [. . . ] If the SECURITY FREEZE LOCK command is issued when the drive is placed in Frozen mode, the drive executes the command, staying in Frozen mode. SMART Feature Set Transcend IDE SSD supports the SMART command set and define some vendor-specific data to report spare/bad block numbers in each memory management unit. Individual SMART commands are identified by the value placed in the Feature register. Table shows these Feature register values.
