(1) To designate the stages in the product development cycle, TI assigns prefixes to the part numbers. These prefixes represent evolutionary stages of product development from engineering prototypes through fully qualified production devices.
Prototype devices are shipped against the following disclaimer:
“This product is still in development and is intended for internal evaluation purposes.”
Notwithstanding any provision to the contrary, TI makes no warranty expressed, implied, or statutory, including any implied warranty of merchantability of fitness for a specific purpose, of this device.
(2) Applies to device max junction temperature.
(3) XJ7200GALM base part number with X speed grade indicator is the part number for the superset device. Software should constrain the features and speed used to match the intended production device.
(4) For High Security (HS) device support, TI recommends the 0, 5 or D device types. The R and P (High Security Prime) device types are not recommended for most applications, as extra steps are required in the manufacturing process and, therefore, these device types are offered at a higher price point.
(5) Only available on preproduction J7200 devices. (Advance Information/Preview)
Note:

BLANK in the symbol or part number is collapsed so there are no gaps between characters.
