As the popularity of using digital companions continue to grow, small form factor portable
media, such as SD, become indispensable in daily life. Coming along with the high demand of
using these kinds of digital storage, its power consumption and performance in content access
are the most important consideration points in selecting end products. Alcor Micro’s PXI2025 single chip flash memory controller is specifically designed as the
solution for building SD memory card. Its high performance, low power consumption and simple
interface can be easily applied it to SD memory card manufacturing. Maintaining multiple NAND flash sources is a common policy seen in memory card manufacturing
industry. It is therefore highly desirable for memory card controller to offer the flexibility
of adopting new firmware. The architecture of FNK2025 supports ISP (In System Programming)
with which memory card manufacturers could change firmware dynamically when there are new flash
needs to be supported. With a specially crafted DMA engine built inside, PXI2025 exhibits high performance data
transfer speed in accessing SLC/MLC/TLC NAND flash. In addition to the performance and compatibility benefits, PXI2025 offers powerful ECC (Error
Code Correction) engine, which is fundamentally important for overcoming the inherent problems
of NAND flash. Moreover, FNK2025 supports CPRM (Content Protection for Recordable Media)
mechanism, which is mandatory to have for playing back digitally secured contents. FNK2025 is available in either 46-pin LGA package or in bare die format |
