Product Summary

The TMS28F200AZ is a 262144 by 8-bit /131072 by-16 bit (2097152-bit), boot-block flash memory that can be electrically block-erased and reprogrammed. The TMS28F200AZ can be ordered in five different voltage configurations. Operation as a 256K-byte (8-bit) or a 128K-word (16-bit) organization is user-definable. WSM status can be monitored by an on-chip status register to determine the progress of program/erase tasks. The TMS28F200AZ features user-selectable block-erasure.
