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.
