FAQ

What is the maximum DDR2 data rate supported by the MPC8377CVRALG?

The MPC8377CVRALG DDR1/DDR2 memory controller supports up to 400 MHz data rate, enabling 3.2 GB/s peak bandwidth on a 64-bit DDR2 interface. This is confirmed in Section 1.1 of Freescale's MPC8377E Hardware Specifications Rev. 8, which specifies "Support for up to 400-MHz data rate" for both DDR1 and DDR2 operation. The MPC8377CVRALG achieves this using GVDD = 1.8 V ±90 mV and requires proper termination and layout per JEDEC standards.

Does the MPC8377CVRALG include a hardware security engine?

Yes, the MPC8377CVRALG includes the SEC 3.0 security engine as a standard feature. As documented in Section 1.8 of the MPC8377E Hardware Specifications, it provides hardware acceleration for DES, 3DES, AES, SHA-1, and MD-5 algorithms via dedicated crypto execution units. The "E" suffix in MPC8377E denotes this integrated engine, and MPC8377CVRALG is a qualified variant of that part.

What package type and pin count does the MPC8377CVRALG use?

The MPC8377CVRALG uses a 783-ball PBGA package with 27 × 27 mm body size and 1.0 mm ball pitch, as specified in Section 22 "Package and Pin Listings" of Freescale Document Number MPC8377EEC Rev. 8. This RoHS-compliant, lead-free package supports fine-pitch routing and thermal dissipation requirements for industrial and networking applications.

Can the MPC8377CVRALG operate as both PCI host and agent?

Yes, the MPC8377CVRALG PCI controller supports both host and agent modes per PCI Specification Revision 2.3, as stated in Section 1.9. It includes on-chip arbitration for up to five external masters in agent mode and selectable coherency enforcement. Mode selection is controlled via configuration pins (CFG_PCI_HOST) at reset, and the CLKIN/PCI_CLK source is automatically selected based on operational mode.

What is the function of the EC_GTX_CLK125 pin on the MPC8377CVRALG?

The EC_GTX_CLK125 pin provides the 125 MHz reference clock for the eTSEC transmitter in RGMII and RTBI modes, as defined in Section 4.3 of the MPC8377E Hardware Specifications. It must meet ±150 ps jitter and 47–53% duty cycle requirements to ensure compliant 1000Base-T operation. This clock is distinct from the system CLKIN and is sourced externally or generated by a companion PHY.
