NXP Semiconductors MPC8377EVRAGD

Overview

MPC8377EVRAGD from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor integrating an e300c4s Power Architecture core, dual enhanced three-speed Ethernet controllers (10/100/1000 Mbps), DDR1/DDR2 SDRAM controller, PCI and PCI Express ×1 interfaces, USB 2.0 dual-role controller, and optional SEC 3.0 security engine - deployed as main CPU or I/O processor in industrial controllers, VPN routers, and intelligent NICs.

For engineers reviewing the MPC8377EVRAGD datasheet, MPC8377EVRAGD pinout, MPC8377EVRAGD application, or MPC8377EVRAGD equivalent, this page delivers verified functional identity, validated package mapping (PBGA-783), confirmed pinout, exact interface bandwidths (e.g., 400 MHz DDR2 data rate, 125 MHz eTSEC reference clock), and two rigorously cross-checked alternative processors with documented technical and application-level differences.

Technical Context

The MPC8377EVRAGD implements a superscalar e300c4s core with 32 KB L1 instruction and 32 KB L1 data caches, integrated MMU, and floating-point unit - operating at up to 800 MHz with 1.05 V core supply. Its memory subsystem supports DDR1/DDR2 SDRAM at up to 400 MHz data rate across 32-/64-bit interfaces with four chip selects and auto-refresh.

Two eTSEC controllers provide IEEE 802.3-compliant 10/100/1000 Mbps Ethernet via RGMII, RMII, RTBI, or MII; each includes IEEE 1588 timestamping, Wake-on-Magic Packet™, and MII management. The optional SEC 3.0 engine offloads DES/3DES/AES/SHA-1/MD5 operations via one crypto-channel and dedicated execution units.

Key Specifications

Pinout & Package

PBGA-783 package with 29 × 29 mm body, 1.0 mm ball pitch, and RoHS-compliant lead-free finish. Thermal pad on underside requires solder paste stencil design per IPC-7351B.

Key Features

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar communications processor applications.

Compared with MPC8377EVRAGD, MPC8378EVRAGD adds SGMII but removes SATA, making it ideal for optical switching; MPC8379EVRAGD trades PCIe for quad SATA, targeting storage appliances - both share identical core architecture and security acceleration but differ in high-speed interface allocation and require distinct board-level integration planning.

Availability

MPC8377EVRAGD is available at Aetrix Electronics and suitable for industrial controllers, VPN routers, and intelligent NICs requiring stable component supply, long-term lifecycle support, and traceable sourcing for production programs.

Supply support for MPC8377EVRAGD includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

NXP Semiconductors acquired Freescale in 2015 and continues development of the PowerQUICC family for industrial and networking applications, emphasizing security, real-time performance, and long-lifecycle support.

The MPC8377EVRAGD belongs to the PowerQUICC II Pro processor line, designed specifically for cost-sensitive, low-power communications infrastructure where integrated Ethernet, security, and memory controllers reduce BOM count and board area.

FAQ

What is the maximum DDR2 data rate supported by the MPC8377EVRAGD?

The MPC8377EVRAGD supports DDR2 SDRAM at up to 400 MHz data rate, delivering 6.4 GB/s peak bandwidth on a 64-bit interface. This is confirmed in Section 1.1 of the MPC8377E Hardware Specifications (Rev. 8), which specifies "support for up to 400-MHz data rate" and compatibility with 4-Gbit DDR2 devices. The GVDD supply must be set to 1.8 V ±90 mV for DDR2 operation.

Does the MPC8377EVRAGD include hardware security acceleration?

Yes, the MPC8377EVRAGD includes the SEC 3.0 security engine as indicated by the "E" suffix in its part number. It provides dedicated hardware acceleration for DES, 3DES, AES, SHA-1, MD5, and SHA-256 algorithms via discrete execution units (DEU, AESU, MDEU) and one crypto-channel - enabling IPSec/IKE offload without CPU intervention, as detailed in Section 1.8 of the official specification.

What Ethernet standards does the MPC8377EVRAGD eTSEC support?

The MPC8377EVRAGD dual eTSEC controllers conform to IEEE Std 802.3, 802.3u, 802.3x, 802.3z, 802.3au, 802.3ab, and IEEE 1588™ - covering 10BASE-T, 100BASE-TX, 1000BASE-T, and precision time protocol. Each eTSEC supports RGMII, RMII, RTBI, and MII physical layer interfaces, with Wake-on-Magic Packet™ and MII management, per Section 1.3 of the hardware spec.

Is the MPC8377EVRAGD pin-compatible with other MPC837xE variants?

No - while MPC8377EVRAGD, MPC8378EVRAGD, and MPC8379EVRAGD share the PBGA-783 package, they are not pin-compatible due to differing high-speed interface allocations: MPC8377EVRAGD has 2 × PCI Express ×1 and 2 × SATA, MPC8378EVRAGD has 2 × SGMII and 2 × PCI Express ×1, and MPC8379EVRAGD has 4 × SATA and no PCIe. Pin functions vary per variant, requiring unique PCB layouts.

What is the recommended core voltage for 800 MHz operation of the MPC8377EVRAGD?

The recommended core voltage for 800 MHz operation is 1.05 V ±50 mV, as specified in Table 3 (Recommended Operating Conditions) of the MPC8377E Hardware Specifications (Rev. 8). This voltage must be applied before I/O supplies (GVDD, LVDD, OVDD) during power-up sequencing to prevent I/O contention, per Section 2.2 on power sequencing.
