6 / 48 page MCF5445x ColdFire® Microprocessor Data Sheet, Rev. 6 Hardware Design Considerations Freescale Semiconductor 6 3.2 Oscillator Power Filtering Figure 3 shows an example for isolating the oscillator power supply from the I/O supply (EVDD) and ground. Figure 3. Oscillator Power Filter 3.3 Supply Voltage Sequencing Figure 4 shows situations in sequencing the I/O VDD (EVDD), SDRAM VDD (SDVDD), PLL VDD (PVDD), and internal logic/core VDD (IVDD). Figure 4. Supply Voltage Sequencing and Separation Cautions The relationship between SDVDD and EVDD is non-critical during power-up and power-down sequences. SDVDD (2.5V or 1.8V) and EVDD are specified relative to IVDD. VDD_OSC 10 Ω 0.1 µF EVDD Pin 1 µF GND VSS_OSC 100 MHz EVDD (3.3V) IVDD, PVDD Time 3.3V 1.5V 0 Notes: 1 Input voltage must not be greater than the supply voltage (EV DD, SDVDD, IVDD, or PVDD) by more than 0.5V at any time, including during power-up. 2 Use 50 V/millisecond or slower rise time for all supplies. 2.5V Supplies Stable SDVDD (2.5V — DDR) 1.8V SDVDD (1.8V — DDR2) |
