NXP Semiconductors MPC8347VVAJFB

Overview

MPC8347VVAJFB from NXP (formerly Freescale) is a PowerQUICC™ II Pro integrated host processor featuring an embedded PowerPC e300 core operating up to 667 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSEC), DDR SDRAM controller supporting 32-/64-bit interfaces at up to 333 MHz (TBGA), PCI 2.2 interface, and hardware-accelerated security engine for IPSec/SSL/TLS. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8347VVAJFB datasheet, MPC8347VVAJFB pinout, MPC8347VVAJFB application, or MPC8347VVAJFB equivalent, key selection criteria include its e300 core frequency, DDR-1 timing compliance, TSEC RGMII/GMII support, PCI host/agent mode flexibility, and integrated crypto-channel architecture - all critical for deterministic real-time networking and secure data path design.

Technical Context

The MPC8347VVAJFB implements a superscalar PowerPC e300 core with 32 KB instruction and 32 KB data L1 caches, lockable cache segments, and dynamic power management. Its DDR SDRAM controller supports programmable timing, ECC, page-mode operation, and registered DIMM compatibility at 2.5-V SSTL2 I/O levels.

It integrates two IEEE 802.3-compliant TSECs with 2 KB TX/RX FIFOs per channel, RMON statistics, jumbo frame (9.6 KB) support, and MII/RGMII/GMII/TBI/RTBI physical layer interfaces. The security engine contains four crypto-channels with dedicated PKEU, DEU, AESU, AFEU, and MDEU units plus RNG.

Key Specifications

Pinout & Package

The MPC8347VVAJFB is housed in a 620-pin TBGA (Thin Ball Grid Array) package with 1.0 mm ball pitch, designed for high-density PCB layouts and thermal performance in networking equipment. Pin assignments follow Freescale's standardized PowerQUICC II Pro layout with dedicated banks for DDR, TSEC, PCI, local bus, and I/O interfaces.

FAQ

What is the maximum DDR-1 data rate supported by the MPC8347VVAJFB?

The MPC8347VVAJFB supports DDR-1 SDRAM at up to 333 MHz data rate in the TBGA package variant, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This is confirmed in Section 6 of the MPC8347EEC Rev. 11 specification under "DDR SDRAM" AC timing tables, where tMCK minimum is 6 ns (166 MHz clock → 333 MHz data rate). The PBGA variant is limited to 266 MHz.

Does the MPC8347VVAJFB support RGMII timing for its Ethernet interfaces?

Yes, the MPC8347VVAJFB supports RGMII (Reduced Gigabit Media Independent Interface) for both TSEC controllers, as explicitly stated in Section 8 ("Ethernet") of the MPC8347EEC Rev. 11 document. RGMII timing compliance includes setup/hold margins for TXD/TXC and RXD/RXC signals referenced to internal clocks, enabling direct connection to RGMII PHYs without external delay elements.

What crypto algorithms are accelerated by the MPC8347VVAJFB security engine?

The MPC8347VVAJFB security engine accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/SHA-256, MD5, HMAC-SHA/MD5, RSA up to 2048 bits, Diffie-Hellman, elliptic curve cryptography (F2m/Fp), and RC4 - all implemented in dedicated execution units (AESU, DEU, MDEU, PKEU, AFEU) as detailed in Section 1 ("Overview") of the MPC8347EEC Rev. 11 spec.

Is the MPC8347VVAJFB pin-compatible with the MPC8349E series?

No, the MPC8347VVAJFB is not pin-compatible with the MPC8349E series. While both share the same TBGA-620 package footprint, pin assignments differ significantly - particularly for DDR address/control signals, USB PHY interface pins, and security engine debug signals. The MPC8349E adds USB OTG-specific pins and reassigns several GPIOs, requiring PCB redesign for migration.

What is the recommended core supply voltage for the MPC8347VVAJFB?

The recommended core supply voltage for the MPC8347VVAJFB is 1.2 V ± 60 mV, as specified in Table 2 ("Recommended Operating Conditions") of the MPC8347EEC Rev. 11 datasheet. This applies to the VDD rail powering the e300 core and internal logic; deviation beyond this range risks timing violations or functional failure, especially above 1.26 V or below 1.14 V.
