10. Static characteristics
[1]
Meets TTL levels, VIO(min) = 2 V and VIH(max) = 0.8 V on non-hysteresis inputs.
[2]
Applies for external output buffers.
[3]
These junction temperatures reect simulated conditions. Absolute maximum junction temperature is 150
°C. The customer is
responsible for verifying junction temperature.
[4]
These parameters apply for D7-D0.
[5]
These parameters apply for DTRA, DTRB, INIA, INTB, RTSA, RTSB, RXRDYA, RXRDYB, TXRDYA, TXRDYB, TXA, TXB.
[6]
Measurement condition, normal operation other than sleep mode:
VCC = 3.3 V; Tamb =25 °C. Full duplex serial activity on all two serial (UART) channels at the clock frequency specied in the
recommended operating conditions with divisor of 1.
[7]
Except x2, VOL = 1 V typical.
[8]
Applies to external clock; crystal oscillator max. 24 MHz.
[9]
When using crystal oscillator. The use of an external clock will increase the sleep current.
