Note 1: All devices are 100% production tested at TA = +25°C.
Note 2: All analog functions disabled and all digital inputs connected to supply or ground.
Note 3: High-speed mode: CPU and three timers running at 8MHz from an external crystal oscillator, CAN enabled and communi-
cating at 500kbps, all other peripherals disabled, all digital I/Os static at DVDDIO or GNDIO.
Note 4: CAN transmitting at 500kbps, one timer output at 500kHz, all active I/Os are loaded with 20pF capacitor, all remaining digi-
tal I/Os are at DVDDIO or GNDIO.
Note 5: Guaranteed by design and characterization.
Note 6: Based on diode ideality factor of 1.008.
Note 7: DVDD must rise above VVDBR for RESET to become deasserted. Caution: Operation is not guaranteed for DVDD below
+2.7V (utility ROM) or +3.0V (flash).
Note 8: RESET is asserted if DVDD falls below VVDBR. Caution: Operation is not guaranteed for DVDD below +2.7V (utility ROM) or
+3.0V (flash).
Note 9: An interrupt is generated if DVDD falls below VVDBI. Caution: Operation is not guaranteed for DVDD below +2.7V (utility
ROM) or +3.0V (flash).
Note 10: An interrupt is generated if DVDDIO falls below VVIOBI. Caution: Operation is not guaranteed if DVDDIO or AVDD is below 4.75V,
except for the DVDDIO brownout monitor and +3.3V linear regulator, that still operate down to 0V and +4.25V, respectively.
