NXP Semiconductors KMPC8358CVRAGDDA

Overview

KMPC8358CVRAGDDA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an e300 PowerPC core running at 400 MHz, integrated QUICC Engine for multi-protocol packet processing (ATM, Ethernet, HDLC, POS), DDR/DDR2 SDRAM controller (32/64-bit, up to 266 MHz), PCI 2.3 interface (32-bit, 66 MHz), and dedicated security engine supporting AES, DES, SHA, RSA, and ECC. It serves as control- and data-plane processor in DSLAMs, 3G Node B interface cards, media gateways, and high-end IADs.

For engineers reviewing the KMPC8358CVRAGDDA datasheet, KMPC8358CVRAGDDA pinout, KMPC8358CVRAGDDA application, or KMPC8358CVRAGDDA equivalent, key selection considerations include e300 core frequency, QUICC Engine protocol support (IEEE 1588, ATM AAL2/AAL5, Gigabit Ethernet via GMII/RGMII), DDR2 memory interface voltage (1.8 V), PCI 3.3-V compliance, and security engine crypto-channel count (4).

Technical Context

The KMPC8358CVRAGDDA implements a dual-domain architecture: the e300 core handles general-purpose control tasks with 32 KB instruction and 32 KB data cache, while the QUICC Engine-two independent 400 MHz RISC controllers-offloads packet processing across six UCCs supporting MII/RMII/RGMII/GMII/TBI/RTBI, ATM SAR, HDLC, and POS. Its DDR controller supports both DDR1 (2.5 V SSTL2) and DDR2 (1.8 V SSTL2) with full ECC, page-mode optimization, and on-die termination.

PCI interface operates in host or agent mode per Revision 2.3, with 32-bit width, 66 MHz max clock, parity, and hardware-enforced coherency. The security engine integrates four crypto-channels with dedicated execution units for AES (128/192/256-bit), DES/3DES, SHA-1/224/256, MD5, HMAC, and RSA up to 2048-bit, plus RNG and XOR parity acceleration for RAID.

Key Specifications

Pinout & Package

KMPC8358CVRAGDDA is housed in a 672-ball plastic ball grid array (PBGA) package with 35 mm × 35 mm body size and 1.0 mm ball pitch, designed for industrial temperature operation (–40°C to +105°C). Pin assignments follow Freescale's MPC8358E Hardware Specifications Rev. 3, with dedicated banks for DDR/DDR2 I/O (GVDD = 1.8 V or 2.5 V), PCI (OVDD = 3.3 V), Ethernet (LVDD = 2.5 V/3.3 V), and core/PLL (VDD/AVDD = 1.2 V).

FAQ

What is the maximum DDR2 data rate supported by KMPC8358CVRAGDDA?

KMPC8358CVRAGDDA 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 capability. This enables reliable 32- or 64-bit memory subsystems for telecom applications requiring high bandwidth and data integrity.

Does KMPC8358CVRAGDDA support IEEE 1588 Precision Time Protocol?

Yes, KMPC8358CVRAGDDA supports IEEE 1588 PTP through its QUICC Engine module, enabling hardware timestamping of Ethernet frames on UCC1–UCC6. This provides sub-microsecond synchronization accuracy critical for 3G Node B and packet-based fronthaul applications.

What are the power supply sequencing requirements for KMPC8358CVRAGDDA?

KMPC8358CVRAGDDA requires VDD and AVDD (1.2 V) to ramp to 90% of nominal value before GVDD, LVDD, or OVDD reach 0.7 V. PORESET must be asserted before power supplies stabilize to prevent I/O contention and excessive current draw during startup.

Can KMPC8358CVRAGDDA operate in PCI agent mode?

Yes, KMPC8358CVRAGDDA supports PCI agent mode per PCI Specification Revision 2.3, allowing it to function as an endpoint device on a PCI bus. It also supports host bridge capabilities, enabling flexible system topology design without external bridge ICs.

What cryptographic algorithms does the KMPC8358CVRAGDDA security engine accelerate?

The KMPC8358CVRAGDDA security engine accelerates AES (128/192/256-bit), DES/3DES, SHA-1/224/256, MD5, HMAC, RSA up to 2048-bit, Diffie-Hellman, and elliptic curve cryptography. It includes four crypto-channels and a random number generator for full IPSec, SSL/TLS, and iSCSI offload.
