35 / 84 page  MPC5604P Microcontroller Data Sheet, Rev. 5 Preliminary—Subject to Change Without Notice Freescale Semiconductor 35 3.6.2 Voltage monitor electrical characteristics The device implements a Power On Reset module to ensure correct power-up initialization, as well as three low voltage detectors to monitor the VDD and the VDD_LV voltage while device is supplied: • POR monitors VDD during the power-up phase to ensure device is maintained in a safe reset state Table 13. Voltage regulator electrical characteristics Symbol Parameter Conditions Min Typ Max Unit VDD_LV_REGCOR P Output voltage under maximum load run supply current configuration Post-trimming 1.145 — 1.4 V RB SR External Resistance on BJT base — 18 — 22 k Ω CDEC1 SR External decoupling/stability ceramic capacitor Bipolar BCP68 or BCX68 or BC817. Three capacitances of 10uF 19.5 30 — µF Bipolar BC817. One capacitance of 22uF 14.3 22 — µF RREG SR Resulting ESR of all four CDEC1 absolute maximum value between 100 kHz and 10 MHz —— 45 m Ω CDEC2 SR External decoupling/stability ceramic capacitor 4 capacitances of 440 nF each 1760 1200 — nF CDEC3 SR External decoupling/stability ceramic capacitor on VDD_HV_REG 2 capacitances of 10 µF each 2 × 10 — — µF Table 14.
