Notes
1. The operating supply current is measured with all output pins disconnected; V
2. The Idle mode supply current is measured with all output pins and RST disconnected; V
3. The Power-down current is measured with all output pins and RST disconnected; V
4. The typical currents are only for the specific block. To calculate the typical power consumption of the microcontroller,
5. Verified on sampling basis.
6. The input threshold voltage of P1.6/SCL and P1.7/SDA meet the I
7. For pin PORENABLE the V
8. Not valid for pins SDA, SCL, RST, MIN and PORENABLE.
9. The maximum allowed load capacitance C
10. The LVD is tested according to the specification in the data sheet “TELX family; Chapter: Low Voltage Detection” .
11. Values are specified for DTMF frequencies only (CEPT CS203).
12. Related to the Low Group Frequency (LGF) component (CEPT CS203).
13. After final testing the value of each EEPROM bit is typically logic 1.
14. Can also be done by two 100 s pulses.

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 (1.8 + 0.11 + 0.09) mA = 2.0 mA.
