Recommended Decoupling Capacitors Symbol Description Min Typ Max Unit Condition Spec Number CDEC Decoupling capacitor (one per supply pin) 1, 2, 3 70 100 — nF — — CBULK Input supply bulk capacitor 2, 4, 5, 6 — 4.7 — µF — — COUT_V15_NPN V15 (1.5V Regulator) output capacitor 2, 7 — 2.2 — µF — — COUT_V11 V11 (1.1V Regulator) output capacitor (all chips, except S32K312, S32K311 & S32K310) 2 — 2.2 — µF — — COUT_V11 V11 (1.1V Regulator) output capacitor (S32K312, S32K311 & S32K310) 2 — 1 — µF — — COUT_V11 V11 (1.1V Regulator) output capacitor (S32K388) 2 — 22 — uF — — COUT_V25 V25 (2.5V Regulator) output capacitor 2, 3 140 220 — nF — — 1. Optionally, 1 nF capacitors can be added in parallel to the decoupling capacitors. 2. All capacitors must be low ESR ceramic capacitors (for example, X7R). The minimum recommendation is after considering component aging and tolerance. 3. These capacitors must be placed as close as possible to the corresponding supply and ground pins. For BGA packages, the capacitors must be placed on the other side of the PCB to minimize the trace lengths. 4. For devices where the VDD_HV_B domain is present, if the VDD_HV_B supply is different supply from VDD_HV_A, a dedicated bulk capacitor is needed.
