The TMS28F1600T / B is a 16777216-bit, boot-block flash memory that can be electrically block-erased and reprogrammed. The TMS28F1600T/B is organized in a sectored architecture consisting of one 16K-byte protected boot sector, two 8K-byte parameter sectors, one 96K-byte main sector, and fifteen 128K-byte main sectors. Operation as a 2M-byte (8-bit) or a 1M-word (16-bit) organization is user-selectable. Embedded program and block-erase functions are fully automated by two on-chip write state machines (WSMs), simplifying these operations and relieving the system microcontroller of these secondary tasks. WSM statuses can be monitored by two on-chip status registers, one for each WSM, to determine progress of program/erase tasks. |
