Electrical characteristics
2 VDDE1 – V DDE4 are separate power segments and may be powered independently with no differential voltage constraints
between the power segments. V DDE1 – V DDE3 pad power segments contain ADC analog input channels and thus the input
analog signal level may be clamped to the V DDE level, resulting in inaccurate ADC results if the V DDE voltage level is less than
V DDA.
3 When VRCSEL = V DDA (high), the internally generated V DD33 voltage may be used to power V DDEMLB as long as the PK[0:2]
pads remain in the disabled default state with their output buffers, input buffers, and pull devices disabled.
4 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.
5 The IHA pads are related to VDDA.
6 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 V DDE = 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 V DDE =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 V DDE =1.62 V.
7 Characterization Based Capability:
IOH_S = {6, 11.6} mA and IOL_S = {9.2, 17.7} mA for {slow, medium} I/O with V DDEH = 4.5 V;
IOH_S = {2.8, 5.4} mA and IOL_S = {4.2, 8.1} mA for {slow, medium} I/O with V DDEH = 3.0 V
8 All VOL /V OH values 100% tested with ±2 mA load.
9 Absolute value of current, measured at VIL and V IH.
10 Weak pull up/down inactive. Measured at VDDE = 5.25 V. Applies to pad types: SH and MH. Leakage specification guaranteed
only when power supplies are within specified operating conditions.
11 Maximum leakage occurs at maximum operating temperature. Leakage current decreases by approximately one-half for each
8 to 12 o C, in the ambient temperature range of 50 to 125 o C. Applies to pad types: pad_a and pad_ae.
