INTRODUCTION
Sharp’s LH28F016SU 16M Flash Memory is a revolutionary architecture which enables the design of truly mobile, high performance, personal computing and communication products. With innovative capabilities, 5 V single voltage operation and very high read/write performance, the LH28F016SU is also the ideal choice for designing embedded mass storage memory systems.

DESCRIPTION
The LH28F016SU is a high performance 16M (16,777,216 bit) block erasable non-volatile random access memory organized as either 1M × 16 or 2M × 8. The LH28F016SU includes thirty-two 64K (65,536) blocks or thirty-two 32-KW (32,768) blocks. A chip memory map is shown in Figure 4.
The implementation of a new architecture, with many enhanced features, will improve the device operating characteristics and results in greater product reliability and ease of use.
