N-Xpress™ NAND Controller (S-Port)
Astoria, as part of its mass storage management functions, fully
manages the SLC and MLC NAND Flash devices. The
embedded 8051 manages the actual reading and writing of the
NAND along with its required protocols. It performs standard
NAND management functions such as ECC and wear leveling.
The Astoria supports single bit ECC for the SLC and 4-bit ECC
for MLC NAND Flash. SLC NAND Flash devices are supported
by CYWB0244ABS. CYWB0244ABM supports both SLC and
MLC NAND Flash devices.
S-Port Configuration Modes
The S Port is configurable in six different interface modes.
•
•
•
•
•
•
NAND Flash Interface Mode
The NAND Flash interface mode configures the S-Port to
interface with NAND Flash devices only. In this interface mode,
the S-Port is configured to interface up to sixteen 8-bit SLC or
MLC NAND Flash

PRELIMINARY
embedded 8051 sets up reading and writing transaction of the
NAND along with its required protocols. It performs standard
NAND management functions such as ECC and wear leveling.
The Astoria supports single bit ECC for the SLC and four bytes
random ECC detection and correction for MLC NAND Flash.
SLC NAND Flash devices are supported by CYWB0244ABS.
CYWB0244ABM supports both SLC and MLC NAND Flash
devices.
SD/SDIO/MMC+/CE-ATA Port (S-Port)
When Astoria is configured with firmware to support SD, SDIO,
MMC+, and CE-ATA, this interface supports:
•
•
•
•
•
West Bridge Astoria provides support for 1-bit and 4-bit SD and
SDIO cards, 1-bit, 4-bit and 8-bit MMC, MMC+ cards, and
CE-ATA drive. For the SD, SDIO, MMC/MMC Plus, and CE-ATA,
this block supports one card for one physical bus interface.
Astoria supports SD commands including the multisector
program command that are handled by the API.
