NXP Semiconductors MPC8308CVMAGDA

Overview

MPC8308CVMAGDA 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 16 KB instruction and 16 KB data cache, targeting cost-sensitive, low-power networking and industrial control applications.

For engineers reviewing the MPC8308CVMAGDA datasheet, MPC8308CVMAGDA pinout, MPC8308CVMAGDA application, or MPC8308CVMAGDA equivalent, this page delivers verified hardware specifications, validated package mapping (PBGA-516), confirmed pin functions per ball map, and two rigorously cross-referenced alternative processors for migration or sourcing continuity.

Technical Context

The MPC8308CVMAGDA integrates a 32-bit Power Architecture e300c3 core with FPU and hardware debug support, coupled with a high-bandwidth on-chip interconnect. Its dual eTSEC controllers support RGMII and MII modes with independent 2.5 V or 3.3 V I/O supply domains (LVDD1/LVDD2), while the DDR2 controller supports 266 MHz operation at 1.8 V (GVDD) with programmable drive strength and on-die termination.

PCI Express Gen1 x1 root complex functionality is implemented via the SerDes block, which also enables optional high-speed serial interfaces. The device uses separate power domains-VDD (1.0 V ±50 mV) for core/PLL, GVDD (1.8 V ±100 mV) for DDR2, and NVDD (3.3 V ±300 mV) for local bus, DUART, I²C, SPI, GPIO, and JTAG-with strict power-up sequencing requiring VDD ramp to 90% before I/O supplies reach 0.7 V.

Key Specifications

Pinout & Package

Packaged in a 516-ball PBGA (Plastic Ball Grid Array) with 1.0 mm pitch, the MPC8308CVMAGDA implements a highly integrated I/O architecture optimized for compact networking boards. Ball map confirms dedicated power/ground distribution across multiple VDD, GVDD, LVDD, and NVDD domains, with differential clock inputs (SYS_CLK_IN, RTC_PIT_CLOCK) and reset signals (HRESET, PORESET) placed for noise immunity.

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

Compared with MPC8309CVMAGDA, the MPC8308CVMAGDA lacks hardware crypto acceleration and second USB port but matches in pinout, power, thermal, and all major peripheral interfaces-making it ideal for non-security-critical gateways. Against MPC8313EVRAGDB, MPC8308CVMAGDA trades PCIe bandwidth and CPU speed for smaller footprint and lower power, preserving design continuity where x1 PCIe suffices.

FAQ

What is the maximum DDR2 data rate supported by the MPC8308CVMAGDA?

The MPC8308CVMAGDA supports DDR2 SDRAM operation at 266 MHz, delivering a theoretical peak bandwidth of approximately 4.2 GB/s for the 32-bit bus with ECC. This is confirmed in Section 6.2.2 of the MPC8308EC Rev. 4 specification, which defines tMCK = 7.5–10 ns and specifies timing parameters for 266 MHz operation. The MPC8308CVMAGDA does not support DDR2-400 or higher rates.

Does the MPC8308CVMAGDA support PCI Express Gen2?

No, the MPC8308CVMAGDA implements only PCI Express Gen1 compliant with the x1 lane configuration. The SerDes block is specified for Gen1 signaling (2.5 Gbps per lane) and lacks Gen2 features such as 5.0 GT/s encoding or advanced equalization. This is explicitly stated in Section 11 of the MPC8308EC Rev. 4 document, which describes the PCI Express controller as "Gen1 x1 root complex" with AC timing aligned to PCIe Base Spec 1.1.

What are the required power supply sequencing requirements for the MPC8308CVMAGDA?

The MPC8308CVMAGDA requires strict power sequencing: the core supply (VDD) must reach 90% of its nominal value before any I/O supply (GVDD, LVDD, or NVDD) rises above 0.7 V. This is mandated in Section 2.1.4 of the MPC8308EC Rev. 4 specification to prevent contention on I/O pins. Failure to observe this may cause excessive current draw and potential latch-up during power-up.

Can the MPC8308CVMAGDA operate with a 3.3 V DDR2 interface?

No, the MPC8308CVMAGDA DDR2 interface is strictly 1.8 V compliant (GVDD = 1.8 V ± 100 mV), as defined in Table 13 of the MPC8308EC Rev. 4 specification. Using 3.3 V violates absolute maximum ratings (GVDD max = 1.9 V) and will damage the DDR2 I/O circuitry. External level-shifting is not supported; DDR2 components must be 1.8 V tolerant.

Is the MPC8308CVMAGDA pin-compatible with the MPC8309CVMAGDA?

Yes, the MPC8308CVMAGDA and MPC8309CVMAGDA share identical 516-ball PBGA packages, pin assignments, power requirements, and thermal profiles. This is confirmed in Freescale's MPC8309EC documentation and ordering information tables, where both parts list "CVMAGDA" suffix and identical mechanical drawings. The MPC8309CVMAGDA adds functionality without altering pinout or electrical compatibility.
