4 VFLASH is only available in the calibration package.

5 Power supply for multi-voltage pads cannot be below 4.5 V when in low-swing mode.

6 The slew rate (SRC) setting must be 0b11 when in low-swing mode.

7 While in low-swing mode there are no restrictions in transitioning to high-swing mode.

8 Pin in low-swing mode can accept a 5 V input.

9 All VOL/VOH values 100% tested with ± 2 mA load except where noted.

10 Bypass mode, system clock at 1 MHz (using system clock divider), PLL shut down, CPU running simple executive

code, 4 x ADC conversion every 10 ms, 2 x PWM channels 1 kHz, all other modules stopped.

11 Bypass mode, system clock at 1 MHz (using system clock divider), CPU stopped, PIT running, all other modules

stopped.

12 This current will be consumed for external regulation and internal regulation, when 3.3V regulator is switched off by

shadow flash

13 If 1.2V and 3.3V internal regulators are on,then iddreg=70mA

If supply is external that is 3.3V internal regulator is off, then iddreg=15mA

14 Power requirements for each I/O segment are dependent on the frequency of operation and load of the I/O pins on a

particular I/O segment, and the voltage of the I/O segment. See Table 22 for values to calculate power dissipation for

specific operation. The total power consumption of an I/O segment is the sum of the individual power consumptions

for each pin on the segment.

15 Absolute value of current, measured at VIL and VIH.

16 Weak pull up/down inactive. Measured at VDDE = 3.6 V and VDDEH = 5.25 V. Applies to fast, slow, and medium pads.

17 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 analog pads.

18 Applies to CLKOUT, external bus pins, and Nexus pins.

19 Applies to the FCK, SDI, SDO, and SDS pins.

20 This programmable option applies only to eQADC differential input channels and is used for biasing and sensor

diagnostics.
