Notes
1. The operating supply current is measured with all output pins disconnected; VIL = VSS; VIH = VDD; RST = VDD; XTAL1
driven with square wave; XTAL2 not connected; fetch of NOP instructions; all derivative blocks disabled.
2. The Idle mode supply current is measured with all output pins and RST disconnected; VIL = VSS; VIH = VDD; XTAL1
driven with square wave; XTAL2 not connected; all derivative blocks disabled.
3. The power-down current is measured with all output pins and RST disconnected; VIL = VSS; VIH = VDD; XTAL1 and
XTAL2 not connected.
4. The typical currents are only for the specific block. To calculate the typical power consumption of the microcontroller,
the current consumption of the CPU must be added. Example: the typical current consumption of the microcontroller
in operating mode with CPU, Watchdog and UART active can be calculated as (3.7 + 0.220 + 0.18) mA = 4.1 mA at
VDD = 3 V and fXTAL = 7 MHz.
5. Verified on sampling basis.
6. The input threshold voltage of P1.6/SCL and P1.7/SDA meet the I2C-bus specification. Therefore, an input voltage
below 0.3VDD will be recognized as a logic 0 and an input voltage above 0.7VDD will be recognized as a logic 1.
7. For pin PORENABLE the VIL max is 0.1VDD.
8. Not valid for pins SDA, SCL, RST and PORENABLE.
9. The maximum allowed load capacitance CL is in this case limited to around 200 pF.
10. The LVD is tested according to the “TELX family specification, Chapter - Low voltage detection”.
11. C1i/C2i are the total internal capacitances (including gate capacitance and leadframe capacitance).
12. Can also be done by two 100 µs pulses.
