Product details
Overview
MPC8308CVMAGD from NXP (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, USB 2.0 HS host/device/OTG, and integrated SerDes. It delivers 400 MHz CPU performance in a 625-ball PBGA package for embedded networking and industrial control applications.
For engineers reviewing the MPC8308CVMAGD datasheet, MPC8308CVMAGD pinout, MPC8308CVMAGD application, or MPC8308CVMAGD equivalent, this page provides verified electrical specs, thermal limits, clocking requirements, reset sequencing, DDR2 interface timing, and validated alternative parts for migration or second-sourcing decisions.
Technical Context
The MPC8308CVMAGD implements a superscalar e300c3 core compliant with Power Architecture v2.03, with 16 KB instruction and 16 KB data cache, FPU, and hardware debug support. Its integrated SerDes block enables RGMII/MII Ethernet, USB ULPI, and high-speed serial interfaces.
It features dual eTSEC controllers supporting full-duplex 10/100/1000 Mbps operation with RGMII (2.5 V) or MII (3.3 V) I/O, a DDR2 memory controller with 1.8 V I/O and MVREF tracking, and PCI Express Gen1 x1 root complex functionality - all coordinated by an enhanced programmable interrupt controller (IPIC) and DMA engine.

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8309CVMAGD | Same package and pinout; adds PCIe x2, second USB 2.0 port, and higher DDR2 bandwidth (333 MHz) | Required for designs needing dual PCIe endpoints or additional USB host capability | Select when PCIe lane count or USB concurrency exceeds MPC8308CVMAGD capacity |
| MPC8313EVRAGD | Higher core frequency (417 MHz), added SEC crypto accelerator, same eTSEC/DDR2/USB feature set | Needed for IPsec/TLS offload or deterministic cryptographic operations in secure gateways | Choose when hardware-accelerated encryption is mandatory and thermal budget allows higher power |
Compared with MPC8308CVMAGD, MPC8309CVMAGD extends PCIe and USB I/O while maintaining identical footprint and software compatibility; MPC8313EVRAGD trades raw CPU speed and crypto acceleration for slightly higher power and no PCIe upgrade - making it optimal for security-first, bandwidth-constrained deployments.

FAQ
What is the maximum DDR2 data rate supported by the MPC8308CVMAGD?
The MPC8308CVMAGD supports DDR2 SDRAM at up to 266 MHz clock frequency, enabling a peak transfer rate of 4.2 GB/s on its 32-bit bus with ECC. This is confirmed in Section 6.2.2 of the MPC8308EC Rev. 4 specification, which defines tMCK minimum of 7.5 ns and output timing parameters valid at 266 MHz. The MPC8308CVMAGD does not support DDR2-333 or higher rates.
Does the MPC8308CVMAGD include a hardware cryptographic accelerator?
No, the MPC8308CVMAGD does not include a dedicated security engine (SEC) or hardware cryptographic accelerator. Its security features are limited to basic memory protection and JTAG lock mechanisms. For hardware-accelerated AES, DES, SHA, or RSA, designers must select alternatives such as the MPC8313EVRAGD, which integrates a full SEC module - a key differentiator explicitly documented in the MPC8313 reference manual.
What are the required power supply sequencing constraints for the MPC8308CVMAGD?
The MPC8308CVMAGD requires core voltage (VDD = 1.0 V) to be applied before any I/O supplies (GVDD, LVDD, NVDD). Specifically, VDD must reach 90% of nominal value before I/O rails exceed 0.7 V, as shown in Figure 3 of MPC8308EC Rev. 4. Violating this sequence may cause bus contention and excessive current draw. PORESET_B must also be asserted after stable VDD and SYS_CLK_IN.
Can the MPC8308CVMAGD operate in RGMII mode with 2.5 V I/O voltage?
Yes, the MPC8308CVMAGD supports RGMII operation with LVDD = 2.5 V ± 125 mV, as specified in Table 2 and Table 22 of MPC8308EC Rev. 4. Its eTSEC controllers are fully compliant with the HP RGMII v1.2a specification, including setup/hold timing for 125 MHz operation. The 2.5 V RGMII mode reduces power versus 3.3 V MII and is the recommended interface for gigabit Ethernet links.
Is the MPC8308CVMAGD pin-compatible with other PowerQUICC II Pro processors like the MPC8313?
No, the MPC8308CVMAGD is not pin-compatible with the MPC8313EVRAGD or MPC8309CVMAGD. Although all three use 625-ball PBGA packages, their ball maps differ significantly - especially for DDR2, PCIe, and USB signals - as confirmed by comparing Sections 20 (MPC8308EC) and 19 (MPC8313RM) of respective hardware specifications. Direct PCB replacement is not possible without layout revision.
