description

The TMS28F200BZx 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 TMS28F200BZx is organized in a blocked architecture consisting of one 16K-byte protected boot block, two 8K-byte parameter blocks, one 96K-byte main block, and one 128K-byte main block. The device can be ordered with either a top or bottom boot-block configuration. Operation as a 256K-by 8-bit or a 128K-by16-bit organization is user-definable.

Embedded program and block-erase functions are fully automated by an on-chip write state machine (WSM), simplifying these operations and relieving the system microcontroller of these secondary tasks. WSM status can be monitored by the on-chip status register to determine the progress of program/erase tasks. The device features user-selectable block-erasure.

The TMS28F200BZx flash memory is offered in a 44-pin PSOP. It is available in two temperature ranges:0°C to 70°C and - 40°C to 85°C.
