NXP Semiconductors MPC8308VMAGDA

Overview

MPC8308VMAGDA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an e300c3 core, dual 10/100/1000 Mbps Ethernet controllers (eTSEC), DDR2 SDRAM controller, PCI Express x1 interface, USB 2.0 HS host/device/OTG, and integrated SerDes. It operates at up to 400 MHz core frequency with 1.0 V ±50 mV core supply and supports industrial temperature range (–40°C to +105°C). It targets network edge routers, industrial gateways, and secure embedded control systems.

For engineers reviewing the MPC8308VMAGDA datasheet, MPC8308VMAGDA pinout, MPC8308VMAGDA application, or MPC8308VMAGDA equivalent, this page delivers verified technical context on its e300c3 architecture, dual eTSEC timing, DDR2 266 MHz interface, RGMII/MII voltage modes, and PCIe x1 electrical compliance - all critical for board-level integration and power sequencing validation.

Technical Context

The MPC8308VMAGDA implements a 32-bit Power Architecture e300c3 core with 16 KB instruction and 16 KB data cache, supporting hardware debug and FPU. Its memory subsystem includes a DDR2 SDRAM controller with 32-bit bus + ECC, programmable drive strength (18 Ω), and MVREF tracking at GVDD/2 ±2%.

Connectivity is defined by two independent eTSEC blocks supporting MII (3.3 V) and RGMII (2.5 V) modes, a PCI Express Gen1 x1 controller, USB 2.0 HS transceiver with ULPI interface, and dual UARTs. Clocking relies on dual PLLs (system and core), each locking within 100 µs, with SYS_CLK_IN acceptance from 24–66.67 MHz.

Key Specifications

Pinout & Package

Applications

Equivalent & Alternatives

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

Compared with MPC8309VMAGDA, MPC8308VMAGDA reduces BOM cost and power by omitting the third eTSEC while retaining full dual-Gigabit capability; versus LS1021A, it preserves Power Architecture software continuity and deterministic eTSEC timing but lacks DDR3L and modern hypervisor features.

FAQ

What is the maximum DDR2 data rate supported by the MPC8308VMAGDA?

The MPC8308VMAGDA supports DDR2 SDRAM at 266 MHz data rate (533 MT/s), with a 32-bit bus width plus ECC. This is confirmed in Section 6 of the MPC8308EC Rev. 4 specification, which specifies tMCK minimum of 7.5 ns and full timing compliance for 266 MHz operation under GVDD = 1.8 V ±100 mV. The MPC8308VMAGDA DDR2 controller does not support 400 MHz DDR2 modes.

Does the MPC8308VMAGDA support RGMII timing at 125 MHz?

Yes, the MPC8308VMAGDA supports RGMII mode at 125 MHz for Gigabit Ethernet operation, as documented in Table 5 (I/O power dissipation) and Section 8.1.1 of the MPC8308EC Rev. 4 spec. RGMII timing requires LVDD = 2.5 V ±125 mV and complies with JEDEC EIA/JESD8-5; the MPC8308VMAGDA's eTSEC blocks meet setup/hold and skew requirements per tDDKHMH (±0.6 ns) at this rate.

What are the power sequencing requirements for the MPC8308VMAGDA?

The MPC8308VMAGDA requires VDD (core) to be applied before GVDD, LVDD, and NVDD, with PORESET asserted until all supplies stabilize. Specifically, VDD must reach 90% of nominal before any I/O supply exceeds 0.7 V, as shown in Figure 3 of MPC8308EC Rev. 4. Violating this sequence risks bus contention and excessive current draw. The MPC8308VMAGDA has no power-down sequencing requirement.

Is the MPC8308VMAGDA pin-compatible with the MPC8309VMAGDA?

Yes, the MPC8308VMAGDA is pin-compatible with the MPC8309VMAGDA: both use identical 620-ball PBGA packages, share identical ball maps for power, clocks, DDR2, eTSEC, PCIe, USB, and control signals, and require identical PCB layout. The MPC8309VMAGDA adds functionality (third eTSEC, 500 MHz option) without altering footprint or signal routing - making it a validated upgrade path for the MPC8308VMAGDA.

What is the operating temperature grade of the MPC8308VMAGDA?

The MPC8308VMAGDA is rated for extended industrial temperature range: –40°C to +105°C junction temperature (TJ), as specified in Table 2 of MPC8308EC Rev. 4. This qualifies it for deployment in uncontrolled environments such as outdoor telecom cabinets, factory floors, and transportation infrastructure where ambient temperatures exceed commercial grade limits.
