eKF5250
USB full speed NAND flash controller
Preliminary
SPECIFICATION
1. General Description
The eKF5250 provides a high-performance interface to bridge USB and NAND Flash
compliance device which can be used to implement of flash memory storage device with USB
interface. It contains a 8-bit RISC processor to greatly reduce firmware development work.
The eKF5250 has a phase Lock Loop(PLL) embedded. The PLL provided all clocks needed
in this Controller. It needs an externally provided clock operating in 2 Mhz.
The eKF5250 can control up to 4 pieces of NAND Flash memory. The flash capacity can be
16M bytes up to 256M bytes. And these chips can be any combination. It has been optimized to
support Toshiba and Samsung flash memory designs. The controller has write-protected ability
to prevent writing data to flash. For read/write operation, the controller can achieve 1000KB
/800KB throughput.
This controller can operate in Win XP, Win2000, Windows ME without any driver
installation.
2. Features
USB Specification v1.1 Compliant
USB Mass Storage Class v1.0 Compliant
Support 12 Mbits/s Full Speed Serial Data Transmission
Support USB Mass Storage Class Bulk-Only Spec.
USB bus-powered capability
Build in PLL used to generate clock for USB. And MCU.
Total 3 Endpoints. Endpoint 0 is the default control endpoint. Endpoint 1 is the
Bulk-in endpoint. Endpoint 2 is the Bulk-out endpoint.
4K x 13 on chip ROM(Program).
Support wear leveling
Support write-protected ability.
Higher reliability : ECC on the fly
Support ping-pong buffer(Two 536x8 bits) for data transfer to/from NAND Flash
Support 4 pieces of NAND Flash.memory
8 Level stack for subroutine nesting.
1 LED sink pin with internal serial resistor.
One 8 bits general purpose timer.
Watchdog Timer with its own on-chip RC oscillator
This specification may change without further notice.
