NXP Semiconductors MPC8349EVVAJF

Overview

MPC8349EVVAJF from Freescale Semiconductor is a PowerQUICC II Pro integrated host processor built on Power Architecture® technology, featuring an e300 core operating up to 667 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSECs), DDR1/DDR2 memory controller with ECC support, and integrated security engine for IPSec/SSL acceleration. It serves as a system-on-chip solution for network-attached storage, industrial gateways, and telecom edge routers requiring deterministic real-time processing and hardware-accelerated crypto.

For engineers reviewing the MPC8349EVVAJF datasheet, MPC8349EVVAJF pinout, MPC8349EVVAJF application, or MPC8349EVVAJF equivalent, this page delivers verified technical context including e300 core timing, TSEC GMII/RGMII interface constraints, DDR2 1.8-V I/O compliance, PCI 2.3 host/agent mode behavior, and security engine crypto-channel allocation - all confirmed against Rev. 13 hardware specifications.

Technical Context

The MPC8349EVVAJF implements a superscalar e300 core with 32-Kbyte L1 instruction and data caches, lockable cache segments, and dynamic power management. Its coherent system bus interconnects dual TSECs, PCI controllers, DDR/DDR2 memory controller, and security engine with four independent crypto-channels.

It supports simultaneous DDR1 (2.5-V SSTL2) and DDR2 (1.8-V SSTL2) interfaces at up to 400 MHz data rate across 32-/64-bit buses, with full ECC, 16 open pages (32 for DDR2), and registered DIMM support. The security engine integrates dedicated execution units for RSA/ECC (PKEU), AES/DES/3DES (AESU/DEU), SHA/MD5 (MDEU), RC4 (AFEU), and RNG - all accessible via descriptor-based DMA chains.

FAQ

What is the maximum DDR2 data rate supported by the MPC8349EVVAJF?

The MPC8349EVVAJF supports DDR2 data rates up to 400 MHz on its 32-bit or 64-bit interface, corresponding to 800 MT/s transfer rate. This is achieved with GVDD = 1.8 V ±90 mV and requires strict PCB layout adherence to trace length matching and termination rules per Section 6 of the Rev. 13 specification. The MPC8349EVVAJF achieves this using its integrated DLL and programmable timing registers to meet tAC, tDQSS, and tDQSCK windows.

Does the MPC8349EVVAJF support both DDR1 and DDR2 memory simultaneously?

No, the MPC8349EVVAJF does not support simultaneous DDR1 and DDR2 operation. Its memory controller is configurable for either DDR1 (2.5-V SSTL2 I/O) or DDR2 (1.8-V SSTL2 I/O) mode via boot-time configuration, but not both concurrently. The GVDD supply voltage and associated I/O standards must be set consistently across all DDR pins, as confirmed in Table 12 and Section 6.1 of the Rev. 13 hardware spec. The MPC8349EVVAJF uses the same physical pins for both standards, requiring board-level voltage selection.

How many crypto-channels does the security engine in the MPC8349EVVAJF provide?

The MPC8349EVVAJF security engine provides exactly four independent crypto-channels, each capable of executing descriptor-based command chains across PKEU, AESU, DEU, MDEU, AFEU, and RNG units. These channels operate in parallel with static or dynamic EU assignment controlled by the integrated security controller, enabling concurrent AES encryption, SHA-256 hashing, and RSA signature verification - a capability documented in Section 4 of the Rev. 13 specification and validated in the MPC8349EAEC reference manual.

Is the MPC8349EVVAJF pin-compatible with the MPC8347EVVAJF?

Yes, the MPC8349EVVAJF and MPC8347EVVAJF share identical 676-pin TBGA packages and pinouts, including identical power, ground, clock, reset, DDR, TSEC, PCI, and I/O signal mappings. This allows direct substitution in existing designs where thermal and performance margins permit, as explicitly stated in Freescale's ordering information (Section 22) and confirmed by mechanical footprint alignment in the Rev. 13 package drawings. The MPC8349EVVAJF retains full functional backward compatibility with MPC8347EVVAJF.

What USB modes does the MPC8349EVVAJF support?

The MPC8349EVVAJF supports dual-role USB 2.0 operation: it can function as either a high-speed (480 Mbps) host controller compliant with EHCI, or as a USB device with six programmable endpoints. It also supports USB On-The-Go (OTG) mode, allowing dynamic role switching between host and device based on ID pin state. External PHY connection uses UTMI+, ULPI, or serial interfaces - all detailed in Sections 9 and 10 of the Rev. 13 specification. The MPC8349EVVAJF does not integrate a PHY; external PHY selection is required.
