MPC750A RISC Microprocessor Hardware Speciﬁcations

Electrical and Thermal Characteristics

1.4.2 AC Electrical Characteristics

This section provides the AC electrical characteristics for the MPC750. After fabrication, parts are sorted

by maximum processor core frequency as shown in Section 1.4.2.1, “Clock AC Speciﬁcations,” and tested

for conformance to the AC speciﬁcations for that frequency. The processor core frequency is determined

by the bus (SYSCLK) frequency and the settings of the PLL_CFG[0–3] signals. Parts are sold by

maximum processor core frequency; see Section 1.10, “Ordering Information”.

1.4.2.1 Clock AC Speciﬁcations

Table 8 provides the clock AC timing speciﬁcations as deﬁned in Figure 3.

Notes:

1. These values apply for all valid 60x bus and L2 bus ratios. The values do not include I/O Supply Power (OVdd and

L2OVdd) or PLL/DLL supply power (AVdd and L2AVdd). OVdd and L2OVdd power is system dependent, but is typically

<10% of Vdd power. Worst case power consumption for AVdd = 15 mW and L2AVdd = 15 mW.

2. Maximum power is measured at Vdd = 2.7V.

3. Typical power is an average value measured at Vdd = AVdd = L2AVdd = 2.6V, OVdd = L2OVdd = 3.3V in a system

executing typical applications and benchmark sequences.

4. Full-On mode is measured using worst-case instruction sequence.
