59 / 86 page ![]() Electrical and Thermal Characteristics MPC5121E/MPC5123 Data Sheet, Rev. 4 Freescale Semiconductor 59 3.3.12 USB ULPI This section specifies the USB ULPI timing. For more information refer to UTMI+ Low Pin Interface (ULPI) Specification, Revision 1.1, October 20, 2004. Figure 39. ULPI Timing Diagram NOTE Output timing is specified at a nominal 50 pF load. 3.3.13 On-Chip USB PHY The USB PHY is an USB2.0 compatible PHY integrated on-chip. See Chapter 7 in the USB Specification Rev. 2.0 at www.usb.org. 3.3.14 SDHC Figure 40 shows the timings of the SDHC. Table 35.
