Secure Digital Card
Wintec’s Secure Digital (SD) cards offer reliable high speed and capacities for capturing extreme resolution images capturing for action burst images.
The Wintec SD cards are optimized for performance, reliability, power and endurance to meet OEM requirements.
It is based on a RISC processor with instruction set extension optimized for Flash handling. The superior wear leveling done by the controller chip involves all physical blocks including the ones containing static data to meet the most demanding requirements from users in a data traffic intensive environment.
Wintec SD cards employs a variety of sophisticated functions, such as BCH error correction code (ECC) for dynamic error checking.
ECC algorithms are implemented on the fly without performance degradation to ensure data reliability. Bad-block Management routines replace worn blocks with spare blocks reserved by the controller on card initialization.
The Wintec SD cards offer capacities ranging from 4GB up to 128GB MLC using industry standard MLC Toggle NAND flash paired with the S3, H6 or P8 controllers. The Wintec SD card optimizes writes to the flash memory and implements highly intelligent block management, wear leveling and lifetime management schemes to increase overall drive endurance and reliability.
