2.3 Current consumption
The tables below give the current consumption for the circuit in different configurations. The figures are indicative
only and may change as a function of the actual software implemented in the circuit.
Table 2-5 gives the current consumption for the flash version of the circuit. The peripherals (USRT, UART, CNT,
VLD, CMPD) are disabled. The parallel ports are configured in input with pull up. Their pins are not connected
externally.

Table 2-6 shows the typical current consumption for the ROM version with 8k instructions. Two possible modes are
possible: a 2.4V-5.5V operating range using the internal regulator and a 1.2V-3.3V operating range short circuiting
the voltage regulator (i.e. connect VREG to VBAT).

1. Software using MOVE instruction using internal CPU registers and peripheral registers.
2. Using the internal voltage regulator (see Figure 2-5).
3. With the internal regulator short circuited (i.e. by connecting VREG to VBAT, see Figure 2-7). In this case, the
current consumption will increase with VBAT.
