–40 to +85 °C, 25 MHz system clock unless otherwise specified. See "AN358: Optimizing Low Power Operation of the
‘F9xx" for details on how to achieve the supply current specifications listed in this table.
Notes:
1. Based on device characterization data; Not production tested.
2. SYSCLK must be at least 32 kHz to enable debugging.
3. Digital Supply Current depends upon the particular code being executed. The values in this table are obtained
4. Includes oscillator and regulator supply current.
5. IDD can be estimated for frequencies <10 MHz by simply multiplying the frequency of interest by the
6. The Supply Voltage is the voltage at the VDD_MCU pin, typically 1.8 to 3.6 V (default = 1.9 V).
7. The supply current specifications in Table 4.2 are for two cell mode. The VBAT current in one-cell mode can

with the CPU executing an “sjmp $” loop, which is the compiled form of a while(1) loop in C. One iteration
requires 3 CPU clock cycles, and the Flash memory is read on each cycle. The supply current will vary
slightly based on the physical location of the sjmp instruction and the number of Flash address lines that
toggle as a result. In the worst case, current can increase by up to 30% if the sjmp loop straddles a 128-byte
Flash address boundary (e.g., 0x007F to 0x0080). Real-world code with larger loops and longer linear
sequences will have few transitions across the 128-byte address boundaries.
frequency sensitivity number for that range, then adding an offset of 90 µA. When using these numbers to

Idle IDD can be estimated by taking the current at 25 MHz minus the difference in current indicated by the
frequency sensitivity number. For example: V

The VBAT Voltage is the voltage at the VBAT pin, typically 0.9 to 1.8 V.
The Supply Current (two-cell mode) is the data sheet specification for supply current.
The Supply Voltage is the voltage at the VDD/DC+ pin, typically 1.8 to 3.3 V (default = 1.9 V).
The DC-DC Converter Efficiency can be estimated using Figure 4.3–Figure 4.5.
