security

The F2810 and F2812 support high levels of security to protect the user firmware from being reversed

engineered. The security features a 128-bit password, which the user programs into the Flash. One code

security module (CSM) is used to protect the Flash/OTP and the L0/L1 SARAM blocks. The security feature

prevents unauthorized users from examining the memory contents via the JTAG port, executing code from

external memory or trying to boot-load some undesirable software that would export the secure memory

contents. To enable access to the secure blocks, the user must write the correct 128-bit 鈥滽EY鈥?value, which

matches the value stored in the password locations within the Flash.

Code Security Module Disclaimer

The Code Security Module (鈥淐SM鈥? included on this device was designed to password

protect the data stored in the associated memory (either ROM or Flash) and is warranted

by Texas Instruments (TI), in accordance with its standard terms and conditions, to

conform to TI鈥檚 published specifications for the warranty period applicable for this device.

TI DOES NOT, HOWEVER, WARRANT OR REPRESENT THAT THE CSM CANNOT BE

COMPROMISED OR BREACHED OR THAT THE DATA STORED IN THE

ASSOCIATED MEMORY CANNOT BE ACCESSED THROUGH OTHER MEANS.

MOREOVER, EXCEPT AS SET FORTH ABOVE, TI MAKES NO WARRANTIES OR

REPRESENTATIONS CONCERNING THE CSM OR OPERATION OF THIS DEVICE,

INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR

A PARTICULAR PURPOSE.

IN NO EVENT SHALL TI BE LIABLE FOR ANY CONSEQUENTIAL, SPECIAL,

INDIRECT, INCIDENTAL, OR PUNITIVE DAMAGES, HOWEVER CAUSED, ARISING

IN ANY WAY OUT OF YOUR USE OF THE CSM OR THIS DEVICE, WHETHER OR NOT

TI HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. EXCLUDED

DAMAGES INCLUDE, BUT ARE NOT LIMITED TO LOSS OF DATA, LOSS OF

GOODWILL, LOSS OF USE OR INTERRUPTION OF BUSINESS OR OTHER

ECONOMIC LOSS.
