NXP Semiconductors KMPC8347VVAJFB

Overview

KMPC8347VVAJFB from Freescale Semiconductor 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 (TSECs), DDR1/DDR2 SDRAM memory controller with ECC support, PCI 2.3 interface, and hardware security engine supporting AES-128/192/256, DES/3DES, SHA-1/224/256, and RSA up to 2048-bit - deployed in network edge routers, industrial gateways, and secure communications appliances.

For engineers reviewing the KMPC8347VVAJFB datasheet, KMPC8347VVAJFB pinout, KMPC8347VVAJFB application, or KMPC8347VVAJFB equivalent, key selection considerations include its 667-MHz e300 core frequency, dual TSEC compliance with IEEE 802.3z/ac, DDR2-400 support at 64-bit width, PCI 3.3-V 32-bit/66-MHz operation, and hardware-accelerated crypto-channel architecture for IPSec/SSL offload.

Technical Context

The KMPC8347VVAJFB implements a superscalar Power Architecture® e300 core with 32-KB instruction and 32-KB data L1 caches, lockable cache segments, and dynamic power management. Its memory subsystem integrates a programmable DDR1/DDR2 SDRAM controller supporting up to four banks, 1-Gbyte per bank, registered DIMMs, and on-the-fly CKE-based power control.

Networking is handled by two independent TSEC modules compliant with IEEE 802.3, 802.3u, 802.3z, and 802.3ac standards, each with 2-KB TX/RX FIFOs, RMON statistics, jumbo frame (9.6 KB) support, and MII/RGMII/TBI/RTBI physical layer interfaces. The security engine contains four crypto-channels with dedicated AESU, DEU, PKEU, MDEU, and RNG units.

Key Specifications

Pinout & Package

KMPC8347VVAJFB is housed in a 689-ball thin quad flat no-lead (TBGA) package with 1.0 mm ball pitch and exposed thermal pad. Pinout follows Freescale's MPC8347EA EC Rev. 12 specification (Section 18), with dedicated banks for DDR2 I/O (GVDD = 1.8 V), TSEC (LVDD = 2.5/3.3 V), PCI (OVDD = 3.3 V), and core/PLL (VDD/AVDD = 1.2–1.3 V).

Equivalent & Alternatives

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

Compared with MPC8349EVRAGDB, KMPC8347VVAJFB trades SATA for lower power and proven crypto throughput; versus LS1023A, it retains Power Architecture toolchain compatibility and hardware-accelerated IPSec but lacks DDR3L and modern ARM features - making it ideal for sustaining legacy carrier-grade infrastructure.

FAQ

What is the maximum DDR2 data rate supported by KMPC8347VVAJFB?

KMPC8347VVAJFB supports DDR2 data rates up to 400 MT/s in 64-bit configuration when implemented in the TBGA package. This corresponds to a 200-MHz clock with double-data-rate transfers, delivering up to 6.4 GB/s theoretical bandwidth - validated for use with JEDEC-compliant DDR2-400 SDRAM components and registered DIMMs.

Does KMPC8347VVAJFB include hardware acceleration for TLS/SSL?

Yes, KMPC8347VVAJFB includes a dedicated security engine with AESU, MDEU, and RNG units that accelerate TLS/SSL cryptographic operations. It supports AES-128/192/256 in CBC/CTR/CCM modes, SHA-1/224/256, and HMAC - enabling full TLS 1.2 handshake offload without CPU intervention, as confirmed in Freescale's MPC8347EA Hardware Specifications Rev. 12.

What package type and thermal characteristics apply to KMPC8347VVAJFB?

KMPC8347VVAJFB uses a 689-ball TBGA package (35 mm × 35 mm, 1.0 mm pitch) with exposed thermal pad. At 667 MHz core frequency and 105°C junction temperature, its typical power dissipation is 4.6 W (TBGA), requiring a minimum θJA of ≤22°C/W for reliable operation - consistent with Freescale's published thermal data in Section 20 of the MPC8347EA EC Rev. 12 document.

Is KMPC8347VVAJFB pin-compatible with other MPC8347 variants?

KMPC8347VVAJFB is pin-compatible with all MPC8347EA revision 3.x silicon variants in the same TBGA package, including MPC8347EVVAJFB and MPC8347EVRAGDB. Pin mappings for DDR2, TSEC, PCI, and core power domains match exactly per Section 18 of the MPC8347EA EC Rev. 12 specification - enabling direct substitution within the same footprint.

What boot sources does KMPC8347VVAJFB support?

KMPC8347VVAJFB supports multiple boot sources including NOR flash via local bus, NAND flash with hardware ECC, SPI flash, and I2C EEPROM. Boot configuration is controlled by CFG_RESET_SOURCE[0:2] pins at reset, and the boot sequencer can load initialization code from I2C-1 EPROM - as documented in Sections 5 and 12 of the MPC8347EA EC Rev. 12 specification.
