PRODUCT OVERVIEW

The VE28F008 is a high-performance 8 Mbit (8,388,608 bit) memory organized as 1 Mbyte (1,048,576 bytes) of 8 bits each. Sixteen 64 Kbyte (65,536 byte) blocks are included on the VE28F008. 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 10,000 cycles. Erase Suspend mode allows system software to suspend block erase to read data or execute code from any other block of the VE28F008.
