1. No floating I/O, unless otherwise specified.

2. RTC enabled. Clock source = LSI

3. RTC enabled, LCD enabled with external VLCD = 3 V, static duty, division ratio = 256, all pixels active, no LCD connected.

4. RTC enabled, LCD enabled with external VLCD, 1/4 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD connected.

5. LCD enabled with internal LCD booster VLCD = 3 V, 1/4 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD

connected.

6. Oscillator bypassed (LSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the LSE consumption

(IDD LSE) must be added. Refer to Table 32

Table 24. Total current consumption and timing in Active-halt mode

at VDD = 1.65 V to 3.6 V (continued)
