Notes:
1. Functional and tested operating conditions are given in Table 5. Absolute maximum ratings are stress ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent damage to the device.
2. Caution: VIN must not exceed OV_DD or L2OV_DD by more than 0.3V at any time including during power-on reset.
3. Caution: L2OV_DD /OV_DD must not exceed VDD/AV_DD /L2AV_DD by more than 1.6V during normal operation. During power-on reset and power-down sequences, L2OVDD/OVDD may exceed VDD/AV_DD /L2AV_DD by up to 3.3V for up to 20 ms, or by 2.5V for up to 40 ms. Excursions beyond 3.3V or 40 ms are not supported.
4. Caution: VDD/AV_DD /L2AV_DD must not exceed L2OVDD/OV_DD by more than 0.4V during normal operation. During power-on reset and power-down sequences, VDD/AVDD/L2AVDD may exceed L2OV_DD /OV_DD by up to 1.0V for up to 20 ms, or by 0.7V for up to 40 ms. Excursions beyond 1.0V or 40 ms are not supported.
5. This is a DC specifications only. VIN may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 5.

Description

The PC755 and PC745 PowerPC® microprocessors are high-performance, lowpower, 32-bit implementations of the PowerPC Reduced Instruction Set Computer (RISC) architecture, especially enhanced for embedded applications.

The PC755 and PC745 microprocessors differ only in that the PC755 features an enhanced, dedicated L2 cache interface with on-chip L2 tags. The PC755 is a drop-in replacement for the award winning PowerPC 750™ microprocessor and is footprint and user software code compatible with the MPC7400 microprocessor with AltiVec™ technology. The PC745 is a drop-in replacement for the PowerPC 740™ microprocessor and PC745 is also footprint and user software code compatible with the PowerPC 603e™ microprocessor. PC755/745 microprocessors provide on-chip debug support and are fully JTAG-compliant.

The PC745 microprocessor is pin compatible with the TSPC603e family.
