58 / 114 page ![]() MPC5646C Microcontroller Data Sheet, Rev. 3 Preliminary—Subject to Change Without Notice Freescale Semiconductor 58 Figure 9. Low voltage monitor vs. Reset 4.9 Low voltage domain power consumption Table 24 provides DC electrical characteristics for significant application modes. These values are indicative values; actual consumption depends on the application. Table 23. Low voltage monitor electrical characteristics Symbol C Parameter Conditions1 1 V DD = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified. Value2 2 All values need to be confirmed during device validation. Unit Min Typ Max VPORUP SR P Supply for functional POR module — 1.0 — 5.5 V VPORH CC P Power-on reset threshold — 1.5 — 2.6 VLVDHV3H CC T LVDHV3 low voltage detector high threshold — 2.7 — 2.85 VLVDHV3L CC T LVDHV3 low voltage detector low threshold — 2.6 — 2.74 VLVDHV5H CC T LVDHV5 low voltage detector high threshold — 4.3 — 4.5 VLVDHV5L CC T LVDHV5 low voltage detector low threshold — 4.2 — 4.4 VLVDLVCORL CC P LVDLVCOR low voltage detector low threshold TA = 25 °C, after trimming 1.143 3 The min. and max variation across process voltage and temperature will be available after device characterization. Expected to be within 10 mV. VLVDLVBKPL CC P LVDLVBKP low voltage detector low threshold 1.143 VDDHV/LV VLVDHVxH/LVxH RESET VLVDHVxL/LVxL |
