Product details
Overview
MPC8358EZQADDDA from Freescale Semiconductor is a PowerQUICC II Pro communications processor featuring an e300 PowerPC core operating at up to 400 MHz, integrated QUICC Engine supporting Ethernet (10/100/1000 Mbps), ATM, HDLC, and POS protocols, DDR/DDR2 SDRAM controller (32-/64-bit, up to 266 MHz), PCI 2.3 interface (32-bit, 66 MHz), and hardware security engine with AES, DES, SHA, and RSA acceleration. 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 MPC8358EZQADDDA datasheet, MPC8358EZQADDDA pinout, MPC8358EZQADDDA application, or MPC8358EZQADDDA equivalent, key selection considerations include its dual-role processing capability, protocol interworking support (ATM-to-Ethernet, PPP, IEEE 1588), DDR2 memory interface compatibility, PCI host/agent mode flexibility, and integrated crypto-acceleration for IPSec/SSL offload in telecom edge equipment.
Technical Context
The MPC8358EZQADDDA 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 comprises two independent 400 MHz RISC controllers managing six UCCs for concurrent multi-protocol handling-including GMII/RGMII/TBI Ethernet, AAL2/AAL5 ATM, and HDLC-via serial DMA and virtual FIFOs.
Hardware acceleration includes a four-channel security engine with dedicated execution units for AES (128/192/256-bit), DES/3DES, SHA-1/224/256, MD5, and RSA up to 2048-bit, plus XOR parity generation for RAID. Memory subsystem supports DDR1 (2.5 V SSTL2) and DDR2 (1.8 V SSTL2) with full ECC, on-die termination, and registered DIMM compatibility.

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8360EVRAGDB | Higher core frequency (667 MHz), dual DDR2 controllers, additional PCIe interface, no UTOPIA/POS support. | Better suited for high-throughput media gateways requiring >1 Gbps encrypted throughput and PCIe-based accelerator cards. | Select when needing higher crypto throughput or PCIe expansion; MPC8358EZQADDDA remains optimal for cost-sensitive ATM/Ethernet interworking deployments. |
| MPC8548ECVRAGDB | e500 core (64-bit Power Architecture), 1333 MT/s DDR2, integrated SerDes, no QUICC Engine - relies on software protocol stacks. | Targeted at Linux-based routing platforms with custom protocol implementations rather than hardware-accelerated telecom protocols. | Choose for general-purpose networking where software flexibility outweighs hardware protocol offload; MPC8358EZQADDDA retains advantage in legacy ATM/POS migration scenarios. |
Compared with MPC8360EVRAGDB and MPC8548ECVRAGDB, the MPC8358EZQADDDA offers unique value in fixed-function telecom edge applications through its QUICC Engine's hardware ATM/Ethernet interworking, UTOPIA/POS interface, and lower-power 400 MHz e300 core - making it ideal for space-constrained, thermally limited DSLAM and IAD designs requiring proven protocol acceleration.

FAQ
What is the maximum DDR2 data rate supported by the MPC8358EZQADDDA?
The MPC8358EZQADDDA 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 efficient packet buffering in media gateways and DSLAMs where sustained memory bandwidth exceeds 4.2 GB/s in 64-bit configuration. The MPC8358EZQADDDA's DDR2 controller also supports registered DIMMs and programmable timing for interoperability with JEDEC-compliant modules.
Does the MPC8358EZQADDDA support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the MPC8358EZQADDDA integrates IEEE 1588 timestamping capability directly into its QUICC Engine UCCs, allowing hardware insertion and extraction of 64-bit timestamps on Ethernet frames with sub-100 ns accuracy. This functionality is essential for time-sensitive applications such as wireless backhaul synchronization and TDM-over-packet transport. The MPC8358EZQADDDA's implementation complies with IEEE 1588-2008 and supports boundary clock and transparent clock modes without CPU intervention.
What security algorithms are accelerated by the MPC8358EZQADDDA's integrated security engine?
The MPC8358EZQADDDA's security engine accelerates AES (128/192/256-bit keys in ECB/CBC/CCM/counter modes), DES/3DES (two- or three-key, ECB/CBC), SHA-1/224/256, MD5, HMAC-SHA/MD5, RSA up to 2048-bit, and RC4 stream cipher. These capabilities enable full IPSec ESP/AH processing, TLS record encryption, and secure boot verification. The MPC8358EZQADDDA's four crypto-channels allow concurrent execution of heterogeneous cryptographic operations, sustaining >100 Mbps encrypted throughput in real-world telecom workloads.
Can the MPC8358EZQADDDA operate in both PCI host and agent modes simultaneously?
No, the MPC8358EZQADDDA supports either PCI host mode or PCI agent mode-not both simultaneously-as determined by the CFG_PCI_MODE strap configuration at reset. In host mode, it drives the PCI bus and manages transactions for attached peripherals; in agent mode, it responds to accesses from an external PCI host. The MPC8358EZQADDDA's single 32-bit PCI interface operates at up to 66 MHz in either configuration, with full support for posted writes, delayed reads, and address translation.
What is the function of the QUICC Engine in the MPC8358EZQADDDA?
The QUICC Engine in the MPC8358EZQADDDA is a dual-core, 400 MHz RISC-based communications coprocessor that offloads protocol processing-including Ethernet MAC, ATM SAR, HDLC framing, PPP, and TDM channelization-from the main e300 core. It manages six UCCs with hardware DMA, virtual FIFOs, and interworking logic for ATM-to-Ethernet bridging and Layer 2 switching. This architecture allows the MPC8358EZQADDDA to sustain line-rate packet processing while maintaining low CPU utilization for control-plane tasks.
