INTRODUCTION
Sharp’s LH28F400SU-LC 4M Flash Memory is a revolutionary architecture which enables the design of truly mobile, high performance, personal computing and communication products. With innovative capabilities, 3.3 V low power operation and very high read/write performance, the LH28F400SU-LC is also the ideal choice for designing embedded mass storage flash memory systems.

DESCRIPTION
The LH28F400SU-LC is a high performance 4M (4,194,304 bit) block erasable non-volatile random access memory organized as either 256K × 16 or 512K × 8. The LH28F400SU-LC includes thirty-two 16K (16,384) blocks. A chip memory map is shown in Figure 5.
