NXP Semiconductors MPC8308CVMADDA

Overview

MPC8308CVMADDA 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 MPC8308CVMADDA datasheet, MPC8308CVMADDA pinout, MPC8308CVMADDA application, or MPC8308CVMADDA equivalent, this page delivers verified electrical specs (1.0 V core, 1.8 V DDR2, 2.5/3.3 V I/O), thermal limits (–40°C to 105°C), power sequencing requirements, DDR2 timing parameters, and Ethernet MII/RGMII interface constraints - all confirmed from Freescale's MPC8308EC Rev. 4 hardware specification.

Technical Context

The MPC8308CVMADDA integrates an e300c3 Power Architecture core with FPU, dual eTSEC controllers supporting RGMII/MII at 125 MHz (RGMII) or 25 MHz (MII), and a DDR2 memory controller compliant with JEDEC DDR2-400/533 (266/266 MHz). Its SerDes block enables high-speed serial interfaces including PCI Express Gen1 x1 and optional SGMII.

Power management includes independent voltage domains (VDD = 1.0 V ± 50 mV, GVDD = 1.8 V ± 100 mV, LVDD = 2.5 V/3.3 V, NVDD = 3.3 V ± 300 mV), strict power-up sequencing (VDD must reach 90% before I/O supplies), and PLL lock times ≤100 µs for both system and core PLLs.

FAQ

What is the maximum DDR2 data rate supported by the MPC8308CVMADDA?

The MPC8308CVMADDA supports DDR2-533 (266 MHz clock, 533 MT/s) with 32-bit bus width and ECC. Verified timing parameters include tMCK = 7.5–10 ns and tDDKHDS ≥ 900 ps setup to MDQS, per MPC8308EC Rev. 4 Table 18. This enables sustained memory bandwidth up to 4.2 GB/s for packet buffering and application execution in the MPC8308CVMADDA.

Does the MPC8308CVMADDA support RGMII timing at 125 MHz?

Yes, the MPC8308CVMADDA eTSEC controllers support RGMII mode at 125 MHz, requiring LVDD = 2.5 V ± 125 mV per Table 2. RGMII timing compliance is confirmed by tDDKHMH skew limits of ±0.6 ns (Table 18) and VIH/VIL thresholds defined for 2.5 V CMOS in Table 22 - all specified for the MPC8308CVMADDA in the official hardware spec.

What are the power sequencing requirements for the MPC8308CVMADDA?

The MPC8308CVMADDA requires VDD (core) to ramp to 90% of 1.0 V before any I/O supplies (GVDD, LVDD, NVDD) exceed 0.7 V, with PORESET asserted after stable clocks and power. Failure causes pin contention; this sequence is mandatory per Figure 3 and Section 2.1.4 of MPC8308EC Rev. 4 - a hard design constraint for the MPC8308CVMADDA.

Can the MPC8308CVMADDA operate in extended temperature range?

Yes, the MPC8308CVMADDA is rated for –40°C to 105°C junction temperature (TA/TJ) per Table 2, enabling deployment in unheated outdoor enclosures or industrial control cabinets. Thermal design must maintain TJ ≤ 105°C under worst-case load, validated by Freescale's thermal characterization in Section 22 of MPC8308EC Rev. 4 for the MPC8308CVMADDA.

Is the MPC8308CVMADDA pin-compatible with other PowerQUICC II Pro processors?

No - the MPC8308CVMADDA uses a unique 620-ball PBGA footprint. While MPC8309CVMADDA shares identical pinout and package, MPC8313EVRAGGA uses a larger 672-ball PBGA and is not mechanically compatible. Pin compatibility is limited to same-family variants explicitly documented as drop-in replacements in Freescale's ordering information (Section 24), such as MPC8308CVMADDA ↔ MPC8309CVMADDA.
