7 / 20 page STA2065 System description Doc ID16050 Rev 1 7/20 2.4.2 SD/MMC STA2065 features three SD/SDIO/MMC interfaces up to 52 MHz / 8-bit. The main clock available to the peripherals is: ● PLL2CLK/13 (when PLL2CLK is 624 MHz and SRC_MMC52 = 0, 48 MHz will be generated) ● PLL2CLK/12 (when PLL2CLK is 624 MHz and SRC_MMC = 1, 52 MHz will be generated) ● PLL2CLK/9 (when PLL2CLK is 432 MHz, 48 MHz will be generated) The peripheral is compliant to the following standards: ● MMC 4.4 ● SD 2.0/Part 1 - Physical Layer ● SD 2.0/Part E1 - SDIO Specification 2.4.3 DDR-SDRAM controller The SDRAM controller has been designed to support up to 1Gbit over each of the two chip selects (or up to 2 Gbit over a single chip select) of: ● LP DDR-SDRAM ● DDR2 The memory data bus will be 16 or 32-bit wide for LP DDR-SDRAM memories (under software control). This same configuration is also supported for DDR2 type of memories, with two 16-bit devices per chip select. 2.4.4 Smartcard interface STA2065 features a smartcard interface compliant to the standard ISO7816-3. STA2065 supports 3.0V or 1.8V type of Cards. 2.5 Audio/video functions 2.5.1 C3 It is composed of CD-ROM Decoder Block, responsible for performing sector descrambling and 3rd level of error correction embedded in the sector specific to CD-ROM mode1 and XA Form1, and Data Filter block supporting frame data filtering and different block layout organization possibilities. The C3 block can take its input data directly from SPDIF or from the memory space, and delivers back its output data to memory, supporting DMA requests. |
