The Actel IGLOO family of reprogrammable, fullfeatured flash FPGAs is designed to meet the demanding power and area requirements of today's portable electronics. Based on the Actel nonvolatile flash technology and single-chip ProASIC®3 FPGA architecture, the 1.2 V / 1.5 V operating voltage family offers the industry's lowest power consumption - as low as 5 µW. The storage daughter board interfaces with Marvell's PXA300/310 processor through the data flash interface (DFI). Arasan SD2.0/ MMC4.2/CE-ATA Host IP core in the Actel IGLOO device provides a low-cost and low-power solution. The Arasan SD2.0/MMC4.2/CE-ATA (CE-ATA 2) Host Controller core consists of the SD 2.0, SDIO 2.0, MMC4.2, and CE-ATA 1.1 controllers. The Arasan CE-ATA 2 Host is fully compliant with the SD Host specification version 2.0 with Advanced-DMA support, MMC specification version 4.2, and CE-ATA Digital Protocol revision 1.1RC. It supports SPI, SD 1-bit, SD 4-bit, and MMC 8-bit modes. The CE-ATA 2 Host core is designed to support high-speed and full-speed SD data transfers. In application with an AHB interface, the Arasan CE-ATA 2 Host core communicates with the ARM® processor at a clock speed up to 300 MHz. The CE-ATA 2 Host controller includes a DMA controller and a FIFO that is expandable from a minimum size of 4 x 32-bit. An optional CPRM functional block can be incorporated to perform a Cipher algorithm for encryption and decryption. • • • • • • • • • • • • • • • The Storage Solution Functional Block Diagram • • • • • Copyright 2007 Arasan Chip Systems Inc. Version 1.0 SD 2.0 Compliant SDIO 2.0 Compliant MMC 4.2 compliant CE-ATA 1.1 compliant S torage Solution for Marvell’s PXA300/310 Platform SD/SDIO Bus Interface Unit: SD 2.0, SDIO 1.2, MMC3.31, MMC4.2, and CE-ATA devices communicate with the host controller through the SD/ MMC Bus Interface Unit (BIU). The BIU consists of the Command Decoder, Response Generator, Transmitter/ Receiver, and Power Control/Switch units. SD1, SD4, and SPI modes are supported. Other BIU functions include the 16-bit CRC generator and checker for the data lines, 7-bit CRC generator and checker for the command and response lines, interrupt state machine, and BIU Master state machine. AHB/APB Interface: The Arasan SD2.0/MMC4.2/CE-ATA Host core provides a Programmed I/O method in which the ARM host driver transfers data using the Buffer Data Port register. The AHB Slave has direct access to the Host Control registers and these registers can be programmed by the ARM processor through the AHB Slave interface. Data transactions are performed through the AHB Slave interface with the Programmed I/O method. The AHB Interface initiates a read or write transaction with the memory if the data transaction is a DMA data transfer. Benefits: • • • • • • Fully compliant core with proven silicon Premier direct support from Arasan core designers Easy-to-use industry standard test environment Unencrypted source code allows easy implementation Customer training available ReUse Methodology Manual guidelines (RMM) compliant verilog code ensured using Spyglass Advanced DMA: The controller supports SDMA, ADMA1, and ADMA2. The Single Operation DMA (SDMA) algorithm forms a performance bottleneck by interruption at every page boundary. ADMA adopts the scatter-gather DMA algorithm so that higher data transfer speed is available. ADMA provides data transfer between system memory and the SD card without interruption of CPU execution. ADMA can support both 32-bit and 64-bit system memory addressing. ADMA1 can support data transfer of only 4 KB aligned data in system memory. ADMA2 improves the restriction so that data of any location and any size can be transferred in system memory. MMC4.2/CE-ATA Interface: The MMC interface conforms with the MMC system specification 4.2. It supports 8-bit MMC mode, Error Correction Code (ECC), MMCplus and MMCmobile card types. The CE-ATA Host Controller conforms with CE-ATA Digital Protocol revision 1.1RC, and with support for CEATA Digital Protocol commands (CMD39 /CMD60 / CMD61). The CE-ATA interface allows for lower pin count, better power utilization, voltages tailored to battery-based applications, and more efficient command protocol.
