MPC8377E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2

Freescale Semiconductor

Overview

In addition to the security engine, new high-speed interfaces such as PCI Express and SATA are included.

Table 1 compares the differences between MPC837xE derivatives and provides the number of ports

available for each interface.

1.1

DDR Memory Controller

The DDR1/DDR2 memory controller includes the following features:

•

Single 32- or 64-bit interface supporting both DDR1 and DDR2 SDRAM

•

Support for up to 400-MHz data rate

•

Support up to 4 chip selects

•

64-Mbit to 2-Gbit (for DDR1) and to 4-Gbit (for DDR2) devices with

×8/×16/×32 data ports (no

direct

×4 support)

•

Support for up to 32 simultaneous open pages

•

Supports auto refresh

•

On-the-fly power management using CKE

•

1.8-/2.5-V SSTL2 compatible I/O

1.2

USB Dual-Role Controller

The USB controller includes the following features:

•

Supports USB on-the-go mode, including both device and host functionality, when using an

external ULPI (UTMI + low-pin interface) PHY

•

Complies with USB Specification, Rev. 2.0

•

Supports operation as a stand-alone USB device

— Supports one upstream facing port

— Supports three programmable USB endpoints

•

Supports operation as a stand-alone USB host controller

— Supports USB root hub with one downstream-facing port

— Enhanced host controller interface (EHCI) compatible

•

Supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation;

low-speed operation is supported only in host mode

•

Supports UTMI + low pin interface (ULPI)
