This section provides the absolute maximum ratings and the recommended operating conditions for the
TMS320F280x DSPs.
6.1 Absolute Maximum Ratings⁽¹⁾⁽²⁾
Unless otherwise noted, the list of absolute maximum ratings are specified over operating temperature ranges.
Supply voltage range, V_DDIO, V_DD3VFL
with respect to V_SS
-0.3 V to 4.6 V
Supply voltage range, V_DDA2, V_DDAIO
with respect to V_SSA
-0.3 V to 4.6 V
Supply voltage range, V_DD
with respect to V_SS
-0.3 V to 2.5 V
Supply voltage range, V_DD1A18, V_DD2A18
with respect to V_SSA
-0.3 V to 2.5 V
Supply voltage range, V_SSA2, V_SSAIO, V_SS1AGND, V_SS2AGND

Output voltage range, V_O
Input clamp current, I_IK (V_IN < 0 or V_IN > V_DDIO)⁽³⁾
-0.3 V to 4.6 V
±20 mA
Output clamp current, I_OK (V_O < 0 or V_O > V_DDIO)
Operating ambient temperature ranges, T_A(4)

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Section 6.2 is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to V_SS, unless otherwise noted.
(3) Continuous clamp current per pin is ± 2 mA. This includes the analog inputs which have an internal clamping circuit that clamps the
voltage to a diode drop above V_DDA2 or below V_SSA2.
(4) Long-term high-temperature storage and/or extended use at maximum temperature conditions may result in a reduction of overall device
life. For additional information, see IC Package Thermal Metrics Application Report (literature number SPRA953) and Reliability Data for
TMS320LF24x and TMS320F281x Devices Application Report (literature number SPRA963)
