The default firmware image implements a USB 2.0 NAND Flash
controller. This controller adheres to the Mass Storage Class
Bulk-Only Transport Specification. The USB port of the
NX2LP-Flex is connected to a host computer directly or through
the downstream port of a USB hub. The host software issues
commands and data to the NX2LP-Flex and receives status and
data from the NX2LP-Flex using standard USB protocol.
The default firmware image supports industry leading 8-bit
NAND Flash interfaces and both common NAND page sizes of
512 and 2k bytes. Up to eight CE# pins enable the NX2LP-Flex
to be connected to up to eight single or four dual-die NAND Flash
chips.
Complete source code and documentation for the default
firmware image are included in the
to enable customization for meeting design requirements.
Additionally, compile options for the default firmware enable
quick configuration of some features to decrease design effort
and increase time-to-market advantages.
Industry standard (SmartMedia) page management for wear
leveling algorithm, bad block handling, and physical to logical
management.
8-bit NAND Flash interface support
Support for 30 ns, 50 ns, and 100 ns NAND Flash timing
Complies with the USB mass storage class specification
