1.1 INTRODUCTION

Samsung's S3F49FAX is NAND flash memory controller which can control flash memories as solid state disk. It

provides PC Card ATA/IDE/USB interface, host and flash transfer rates up to 20.0MB/S. S3F49FAX can control

flash memory maximum 8 pieces. The device is designed using 0.35um CMOS process, assembled as 100-TQFP

package. It supports operation in both 5.0V and 3.3V.

An outstanding feature of the S3F49FAX flash disk controller is its CPU core: the ARM7TDMI 16/32-bit RISC

processor, designed by Advanced RISC Machine (ARM), Ltd. The ARM core is a low-power, general purpose,

microprocessor macro-cell that was developed for use in application-specific and customer-specific integrated

circuit. It is simple, elegant, and fully static design is particularly suitable for cost and power sensitive application.
