Operating Current Specifications
2 Voltage overshoots during a high-to-low or low-to-high transition must not exceed 10 seconds per instance.
3 5.3 V for 10 hours cumulative time, 3.3 V +10% for time remaining.
4 6.4 V for 10 hours cumulative time, 5.0 V +10% for time remaining.
5 V
DDE1 – VDDE4 are separate power segments and may be powered independently with no differential voltage constraints
between the power segments. VDDE1 – VDDE3 pad power segments contain ADC analog input channels and thus the input
analog signal level may be clamped to the VDDE level, resulting in inaccurate ADC results if the VDDE voltage level is less than
VDDA.
6 When V
RCSEL = VDDA (high), the internally generated VDD33 voltage may be used to power VDDEMLB as long as the PK[0:2]
pads remain in the disabled default state with their output buffers, input buffers, and pull devices disabled.
7 The pad type is indicated by one or more of the following abbreviations: A–analog, F—fast speed, H–high voltage, I—input-only,
M–medium speed, S–slow speed. For example, pad type SH designates a slow high-voltage pad.
8 The IHA pads are related to V
DDA.
9 Characterization Based Capability:
IOH_F = {12, 20, 30, 40} mA and IOL_F = {24, 40, 50, 65} mA for {00, 01,10, 11} drive mode with VDDE = 3.0 V;
IOH_F = {7, 13, 18, 25} mA and IOL_F = {18, 30, 35, 50} mA for {00, 01, 10, 11} drive mode with VDDE =2.25 V;
IOH_F = {3, 7, 10, 15} mA and IOL_F = {12, 20, 27, 35} mA for {00, 01, 10, 11} drive mode with VDDE =1.62 V.
10 Characterization Based Capability:
IOH_S = {6, 11.6} mA and IOL_S = {9.2, 17.7} mA for {slow, medium} I/O with VDDEH = 4.5 V;
IOH_S = {2.8, 5.4} mA and IOL_S = {4.2, 8.1} mA for {slow, medium} I/O with VDDEH = 3.0 V
11 All V
OL/VOH values 100% tested with ±2 mA load.
12 Absolute value of current, measured at V
IL and VIH.
13 Weak pull up/down inactive. Measured at V
DDE = 5.25 V. Applies to pad types: SH and MH. Leakage specification guaranteed
only when power supplies are within specified operating conditions.
14 Maximum leakage occurs at maximum operating temperature. Leakage current decreases by approximately one-half for each
8 to 12 oC, in the ambient temperature range of 50 to 125 oC. Applies to pad types: pad_a and pad_ae.
