DESCRIPTION

The LH28F008SA is a high-performance 8M (8,388,608 bit) memory organized at 1M (1,048,576 bytes) of 8 bits each. Sixteen 64K (65,536 Byte) blocks are included on the LH28F008SA. A memory map is shown in Figure 4 of this specification. A block erase operation erases one of the sixteen blocks of memory in typically 1.6 seconds, independent of the remaining blocks. Each block can be independently erased and written 100,000 cyles. Erase Suspend mode allows sys tem software to suspend block erase to read data or execute code from any other block of the LH28F008SA.
