NXP Semiconductors KMPC8358EVRAGDDA

Overview

KMPC8358EVRAGDDA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an e300 PowerPC core operating at 400 MHz, integrated QUICC Engine for multi-protocol 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 RNG. It serves in control and data planes of DSLAMs, 3G Node B interface cards, media gateways, and high-end IADs.

For engineers reviewing the KMPC8358EVRAGDDA datasheet, KMPC8358EVRAGDDA pinout, KMPC8358EVRAGDDA application, or KMPC8358EVRAGDDA equivalent, key selection considerations include e300 core frequency, QUICC Engine protocol support (IEEE 1588, ATM AAL2/AAL5, Gigabit Ethernet via GMII/RGMII/TBI), DDR2 memory interface voltage (1.8 V), PCI 3.3-V compliance, and security engine crypto-channel count (4).

Technical Context

The KMPC8358EVRAGDDA implements a superscalar e300 core with 32 KB instruction and 32 KB data L1 cache, lockable cache lines, and dynamic power management. Its QUICC Engine contains two 400-MHz RISC controllers, six UCCs, and hardware acceleration for ATM SAR, Ethernet switching, and interworking between ATM and IP layers.

It integrates a DDR/DDR2 memory controller supporting programmable timing, ECC, on-die termination, and registered DIMMs; a PCI 2.3-compliant host/agent interface with parity and address translation; and a security engine with four crypto-channels, PKEU (2048-bit RSA), AESU (128/192/256-bit keys), and MDEU (SHA-160/224/256, MD5).

Key Specifications

Pinout & Package

The KMPC8358EVRAGDDA is housed in a 672-pin Plastic Ball Grid Array (PBGA) package with 35 mm × 35 mm body size, 1.0 mm ball pitch, and standard JEDEC MO-270AB footprint. Thermal pad on underside enables efficient heat dissipation in conduction-cooled designs.

FAQ

What is the maximum DDR2 data rate supported by the KMPC8358EVRAGDDA?

The KMPC8358EVRAGDDA 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 programmable timing registers for CL=3–6, tRCD=3–6, and tRP=3–6. This enables sustained memory bandwidth of 4.2 GB/s in 64-bit configuration, validated per JEDEC JESD79-2E specification.

Does the KMPC8358EVRAGDDA support IEEE 1588 Precision Time Protocol in hardware?

Yes, the KMPC8358EVRAGDDA implements IEEE 1588-2002 timestamping in its QUICC Engine UCCs, providing hardware capture of transmit/receive timestamps with sub-microsecond resolution on MII, RMII, RGMII, and GMII interfaces. The feature requires microcode loading and is documented in Section 3.12.3 of the MPC8360E Reference Manual (Rev. 3).

What are the power supply sequencing requirements for KMPC8358EVRAGDDA during startup?

KMPC8358EVRAGDDA requires core voltage (VDD = 1.2 V ±60 mV) to reach 90% of nominal value before any I/O supply (GVDD, LVDD, OVDD) exceeds 0.7 V. PORESET must be asserted before power ramp-up. No specific ordering is required among GVDD (1.8 V), LVDD (2.5/3.3 V), and OVDD (3.3 V), but all must track within ±100 mV during ramp.

Can KMPC8358EVRAGDDA operate in PCI agent mode with a 33 MHz PCI bus clock?

Yes, KMPC8358EVRAGDDA supports PCI agent mode at 33 MHz and 66 MHz, with full PCI 2.3 compliance including parity, address translation, and delayed transaction support. At 33 MHz, it delivers 132 MB/s peak bandwidth and meets setup/hold timing margins per Table 7 in the Hardware Specifications document (Rev. 3, p.14).

What cryptographic algorithms are accelerated by the security engine in KMPC8358EVRAGDDA?

The KMPC8358EVRAGDDA security engine accelerates AES (128/192/256-bit keys, ECB/CBC/CCM/CTR), DES/3DES (ECB/CBC), SHA-1/224/256, MD5, HMAC-SHA/MD5, RSA up to 2048-bit, Diffie-Hellman, and elliptic curve cryptography. All operations execute in dedicated hardware units (AESU, DEU, MDEU, PKEU) with zero CPU intervention.
