NXP Semiconductors KMPC8358CVRAGDGA

Overview

KMPC8358CVRAGDGA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an e300 PowerPC core operating at up to 400 MHz, integrated QUICC Engine module supporting Ethernet (10/100/1000 Mbps), ATM, HDLC, and POS protocols, DDR/DDR2 SDRAM controller with 32-/64-bit interface up to 266 MHz, PCI 2.3-compliant 32-bit bus at 66 MHz, and hardware security engine supporting AES, DES, SHA, RSA, and RNG. It serves as control- and data-plane processor in DSLAMs, 3G Node B base station cards, media gateways, and high-end IADs.

For engineers reviewing the KMPC8358CVRAGDGA datasheet, KMPC8358CVRAGDGA pinout, KMPC8358CVRAGDGA application, or KMPC8358CVRAGDGA equivalent, key selection criteria include e300 core frequency headroom, QUICC Engine protocol flexibility (IEEE 1588, AAL2/AAL5, RGMII/GMII), DDR2 timing compliance, PCI host/agent mode configurability, and integrated crypto-channel concurrency for IPSec/SSL offload.

Technical Context

The KMPC8358CVRAGDGA implements a dual-domain architecture: the e300 core handles general-purpose control tasks and OS execution, while the QUICC Engine-two independent 400-MHz RISC controllers-manages real-time packet processing across six UCCs supporting simultaneous Ethernet, ATM, HDLC, and TDM traffic. Its DDR2 controller supports 1.8-V SSTL2 I/O, on-die termination, and 32/64-bit configurable bus width with full ECC and page-mode optimization.

PCI operation is strictly 3.3-V compliant per Revision 2.3, with host bridge capability, programmable coherency enforcement, and support for delayed reads and posted writes. The security engine provides four parallel crypto-channels with dedicated execution units for AES (128/192/256-bit), DES/3DES, SHA-1/224/256, MD5, and RSA up to 2048 bits-enabling concurrent IPsec SA processing without CPU intervention.

Key Specifications

Pinout & Package

KMPC8358CVRAGDGA uses a 672-ball plastic ball grid array (PBGA) package with 1.0 mm pitch, 35 mm × 35 mm body size, and thermal pad on underside. Pinout is defined in Section 21 of MPC8358EEC Rev. 3, with critical signal groups including DDR2 address/data/control (A0–A15, DQ0–DQ63, DQS0–DQS7), PCI AD[0:31]/C/BE[0:3], six UCC serial interfaces (TxD/RxD/MCLK/RTS/CTS), and QUICC Engine clock inputs (QE_CLKIN0–QE_CLKIN3).

Manufacturer

NXP Semiconductors acquired Freescale in 2015 and maintains the PowerQUICC II Pro portfolio for legacy telecom infrastructure. NXP focuses on secure, high-reliability processors for industrial and networking applications.

KMPC8358CVRAGDGA belongs to the PowerQUICC II Pro family, designed specifically for cost-sensitive, multi-protocol communications equipment where integrated QUICC Engine offload, hardware security, and DDR2/PCI interoperability reduce BOM count and system power.

FAQ

What is the maximum DDR2 data rate supported by KMPC8358CVRAGDGA?

KMPC8358CVRAGDGA supports DDR2 SDRAM at up to 266 MHz data rate (533 MT/s), with 1.8-V SSTL2-compatible I/O, on-die termination, and full ECC. This enables 4.3 GB/s peak bandwidth in 64-bit configuration and is validated for Micron MT47H64M8CF-25E and Samsung K4T51163QG-BCE7 modules per MPC8358EEC Rev. 3.

Does KMPC8358CVRAGDGA support IEEE 1588 Precision Time Protocol?

Yes, KMPC8358CVRAGDGA supports IEEE 1588-2002 PTP in hardware via its QUICC Engine module. The UCC Ethernet controllers provide timestamping accuracy of ±50 ns on transmit/receive paths, and the e300 core synchronizes system time using the integrated periodic interrupt timer and real-time clock registers.

Can KMPC8358CVRAGDGA operate in PCI host mode with a 66 MHz clock?

Yes, KMPC8358CVRAGDGA supports PCI host mode at 66 MHz per PCI Specification Revision 2.3. The PCI interface requires 3.3-V signaling only and provides host bridge functionality with address translation, coherency enforcement, and support for delayed reads and posted writes as confirmed in Section 12 of MPC8358EEC Rev. 3.

What crypto algorithms are accelerated by the KMPC8358CVRAGDGA security engine?

KMPC8358CVRAGDGA's security engine accelerates AES (128/192/256-bit in ECB/CBC/CCM/counter modes), DES/3DES (ECB/CBC), SHA-1/224/256, MD5, HMAC-SHA/MD5, RSA up to 2048 bits, Diffie-Hellman, and elliptic curve cryptography. All operations execute in dedicated hardware units with four concurrent crypto-channels.

Is KMPC8358CVRAGDGA pin-compatible with other PowerQUICC II Pro processors?

No, KMPC8358CVRAGDGA is not pin-compatible with MPC8360CVRAGDGA or KMPC8379CVRAGDGA. While all use 672-ball PBGA packages, ball assignments differ significantly for DDR2, PCI, and UCC signals. Migration requires PCB redesign and layout validation per respective package drawings in MPC8358EEC, MPC8360EEC, and MPC8379EEC.
