Table of Contents description The TMS28F400Axy is a 524 288 by 8 bits / 262 144 by 16 bits (4 194 304-bit), boot-block flash memory that can be electrically block-erased and reprogrammed. The TMS28F400Axy is organized in a blocked architecture consisting of: D One 16K-byte protected boot block D Two 8K-byte parameter blocks D One 96K-byte main block D Three 128K-byte main blocks Table 1 lists the five different voltage configurations available for ordering. Operation as a 512K-byte (8-bit) or a 256K-word (16-bit) organization is user-definable. Table 1.
