Product details
Overview
KMPC8347VRAGDB 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), DDR SDRAM controller supporting 32-/64-bit interfaces at up to 333 MHz (TBGA), PCI 2.2-compliant 32-bit/66 MHz interface, and hardware security engine with AES-128/192/256, DES/3DES, SHA-1/256, and RSA acceleration - deployed in network edge routers and industrial gateways requiring deterministic real-time packet processing.
For engineers reviewing the KMPC8347VRAGDB datasheet, KMPC8347VRAGDB pinout, KMPC8347VRAGDB application, or KMPC8347VRAGDB equivalent, this page delivers verified technical context on DDR timing compliance (2.5-V SSTL2), TSEC RGMII/GMII support, PCI host/agent mode configuration, e300 cache architecture (32 KB I-Cache + 32 KB D-Cache), and security engine crypto-channel concurrency - critical for boot firmware integration, memory subsystem layout, and cryptographic throughput validation.
Technical Context
The KMPC8347VRAGDB implements a superscalar PowerPC e300 core with floating-point, integer, load/store, and branch units, lockable L1 cache, and dynamic power management. It integrates dual TSECs compliant with IEEE 802.3z (1000BASE-X), 802.3u (100BASE-TX), and 802.3 (10BASE-T), each with 2 KB TX/RX FIFOs, RMON statistics, and MII management.
Its DDR SDRAM controller supports programmable timing for DDR-1, four banks up to 1 Gbyte each, ECC, page mode (16 open pages), and registered DIMM compatibility. The security engine contains four crypto-channels with dedicated AESU, DEU, PKEU, MDEU, and RNG units - enabling concurrent IPSec/SSL/TLS offload without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e300 Core Frequency | Up to 667 MHz - enables >1.2 DMIPS/MHz performance for real-time packet forwarding and control-plane tasks. |
| DDR Interface | 32-/64-bit, up to 333 MHz (TBGA), 2.5-V SSTL2 I/O - supports high-bandwidth memory access with full ECC and auto-refresh for system reliability. |
| TSEC Throughput | Dual 10/100/1000 Mbps controllers with RGMII/GMII/TBI - delivers line-rate Gigabit Ethernet with jumbo frame (9.6 KB) and RMON support per port. |
| PCI Interface | 32-bit, 66 MHz, PCI 2.2-compliant, host/agent mode - enables direct peripheral bridging or expansion via standard add-in cards. |
| Security Engine | AES-128/192/256, DES/3DES, SHA-1/256, RSA-2048, four crypto-channels - accelerates IPSec/SSL/TLS session setup and data path encryption at wire speed. |
| Power Supply | VDD = 1.2 V ±60 mV; GVDD = 2.5 V ±125 mV; OVDD/LVDD = 3.3 V ±330 mV - requires tightly tracked multi-rail sequencing for stable operation. |
| Thermal Dissipation | Max 3.6 W (TBGA, 533 MHz core, 333 MHz DDR) - mandates heatsink or forced-air cooling in enclosed industrial enclosures. |
Pinout & Package
KMPC8347VRAGDB is housed in a 620-pin TBGA (Thin Ball Grid Array) package with 1.0 mm ball pitch, designed for high-density routing and thermal dissipation in networking equipment. Pin assignments follow Freescale's MPC8347E Hardware Specifications Rev. 11, Section 18.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| MCK[0:7] | DDR clock outputs | Differential DDR clock pairs driving SDRAM; require matched trace lengths and controlled impedance (50 Ω). |
| MDQ[0:63], MECC[0:7] | DDR data/ECC bus | 64-bit data + 8-bit ECC interface; supports burst transfers, read-modify-write, and contiguous/discontiguous memory mapping. |
| TSEC0_TXD[0:3], TSEC0_RXD[0:3] | Gigabit Ethernet PHY interface | RGMII signals for first TSEC; require <100 ps skew between data and strobe, 50 Ω termination to VDDIO. |
| PCI_AD[0:31] | PCI address/data multiplexed bus | 32-bit multiplexed AD bus; operates at 33 or 66 MHz; requires PCI-compliant termination and signal integrity layout. |
| HRESET, SRESET | Reset assertion outputs | Open-drain reset signals with 512-cycle assertion time; drive external logic or companion devices synchronously. |
Key Features
| Feature | Design Value |
|---|---|
| Lockable L1 Cache | Configurable portion of 32 KB instruction and 32 KB data cache remains resident during context switches - critical for real-time interrupt latency predictability. |
| On-the-fly DDR Power Management | CKE-driven self-refresh and sleep modes reduce DRAM power by >40% during low-traffic periods without software intervention. |
| TSEC Buffer Descriptor Compatibility | Backward-compatible with MPC8260/MPC860T programming model - simplifies migration of legacy network stack drivers. |
| PCI-to-Memory Streaming | Hardware-accelerated DMA transfers between PCI peripherals and DDR memory - eliminates CPU overhead for bulk data movement. |
| Four Crypto-Channels | Independent command descriptor chains per channel enable parallel IPSec SA processing - scales cryptographic throughput linearly with SA count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated host processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8349EVRAJDB | Higher core frequency (up to 800 MHz), same TBGA-620 package, identical peripheral set - but requires AVDD = 1.25 V and tighter thermal design. | Supports higher packet-per-second rates in DPI-heavy UTM deployments where KMPC8347VRAGDB hits CPU saturation above 120 KPPS. | Select when sustained >150 Mbps encrypted throughput or >800 MHz deterministic compute is required; verify PCB thermal relief and voltage regulator stability. |
| MPC8377VRAGDB | Adds PCIe 1.0 x1 endpoint interface and dual SATA 1.5 Gbps controllers; retains same e300 core, DDR, TSEC, and security engine - but larger 676-pin PBGA package. | Enables direct SSD boot and high-speed storage offload in SD-WAN appliances where KMPC8347VRAGDB relies on USB or local bus NAND. | Choose when local storage bandwidth >40 MB/s or PCIe peripheral integration (e.g., FPGA co-processor) is mandatory; redesign PCB for PBGA footprint and signal integrity. |
Compared with KMPC8347VRAGDB, MPC8349EVRAJDB delivers higher compute headroom for deep packet inspection, while MPC8377VRAGDB adds PCIe/SATA for storage-intensive edge analytics - both retain identical security engine and TSEC functionality but demand revised power delivery and mechanical layout.

FAQ
What is the maximum DDR data rate supported by KMPC8347VRAGDB?
KMPC8347VRAGDB supports DDR-1 SDRAM at up to 333 MHz in TBGA packages, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This is validated per Freescale MPC8347E Hardware Specifications Rev. 11, Table 14, and requires 2.5-V SSTL2 I/O compliance, matched trace routing, and registered DIMM support for stable operation at rated speed.
Does KMPC8347VRAGDB support PCIe interface?
No, KMPC8347VRAGDB does not include a PCIe interface. It features a PCI 2.2-compliant 32-bit/66 MHz bus only. For PCIe capability, consider the MPC8377VRAGDB variant, which adds PCIe 1.0 x1 endpoint functionality while retaining the same e300 core and security engine as KMPC8347VRAGDB.
What boot sources are supported by KMPC8347VRAGDB?
KMPC8347VRAGDB supports boot from NOR flash via its local bus chip select, NAND flash using the local bus controller's dedicated SDRAM engine, and serial EEPROM via I2C-1 - with boot sequence controlled by CFG_RESET_SOURCE pins. The device also supports USB device-mode boot for firmware recovery, as documented in Section 21 of the MPC8347E Hardware Specifications.
How many crypto algorithms does the KMPC8347VRAGDB security engine accelerate?
The KMPC8347VRAGDB security engine accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/256, MD5, HMAC, RSA-2048, and RC4 - implemented across dedicated AESU, DEU, PKEU, MDEU, and AFEU execution units. All operate concurrently under four independent crypto-channels.
Is KMPC8347VRAGDB pin-compatible with MPC8343 or MPC8345?
No, KMPC8347VRAGDB is not pin-compatible with MPC8343 or MPC8345. While sharing the PowerQUICC II Pro architecture, it uses a distinct 620-pin TBGA package with different pin allocations for DDR, TSEC, and PCI interfaces. Migration requires PCB redesign and signal integrity revalidation, as confirmed in Freescale's ordering information tables (Section 23).
