NXP Semiconductors MPC8349CZUAJDB

Overview

MPC8349CZUAJDB 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 TSEC Ethernet controllers, DDR1/DDR2 SDRAM memory controller (32-/64-bit, up to 400 MHz data rate), and integrated security engine supporting AES, DES, SHA, RSA, and RNG. It targets network-attached storage, industrial gateways, and secure edge routers requiring deterministic real-time processing and hardware-accelerated cryptography.

For engineers reviewing the MPC8349CZUAJDB datasheet, MPC8349CZUAJDB pinout, MPC8349CZUAJDB application, or MPC8349CZUAJDB equivalent, key selection considerations include its 667-MHz e300 core performance, dual TSEC gigabit Ethernet with RGMII/TBI support, DDR2-400 memory interface with ECC, PCI 2.3-compliant dual bus architecture, and on-die security acceleration for IPSec/SSL offload - all in a 676-pin TBGA package.

Technical Context

The MPC8349CZUAJDB implements a superscalar Power Architecture® e300 core with 32-Kbyte L1 instruction and data caches, lockable cache segments, and dynamic power management. Its coherent system bus interconnects dual TSECs, PCI controllers, DDR/DDR2 memory controller, and security engine with four crypto-channels.

It supports simultaneous DDR1 (2.5-V SSTL2) and DDR2 (1.8-V SSTL2) interfaces with full ECC, up to four physical banks, and 16 open pages (32 for DDR2). The security engine integrates dedicated execution units for AES (128/192/256-bit), DES/3DES, SHA-1/224/256, MD5, RSA up to 2048-bit, and true random number generation.

FAQ

What is the maximum DDR2 data rate supported by the MPC8349CZUAJDB?

The MPC8349CZUAJDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock), delivering 3.2 GB/s peak bandwidth on a 64-bit interface. This is confirmed in Section 6 of the MPC8349EA Hardware Specifications (Rev. 13), which applies to MPC8349CZUAJDB as a pin- and function-equivalent variant. The DDR2 controller supports 1.8-V SSTL2 I/O, full ECC, and up to four physical banks.

Does the MPC8349CZUAJDB include hardware cryptographic acceleration?

Yes, the MPC8349CZUAJDB integrates a dedicated security engine with four crypto-channels and execution units for AES (128/192/256-bit), DES/3DES, SHA-1/224/256, MD5, RSA up to 2048-bit, and true random number generation. This allows full IPSec and SSL/TLS offload without CPU intervention - a core feature documented in Section 1 of the MPC8349EA Hardware Specifications.

What package type and ball count does the MPC8349CZUAJDB use?

The MPC8349CZUAJDB uses a 676-ball TBGA package (27 mm × 27 mm, 1.0 mm pitch) with exposed thermal pad. This is explicitly defined in Section 18 ("Package and Pin Listings") of the MPC8349EA Hardware Specifications Rev. 13, which covers all orderable variants including MPC8349CZUAJDB. The package supports lead-free assembly and RoHS compliance.

Can the MPC8349CZUAJDB operate in both PCI host and agent modes?

Yes, the MPC8349CZUAJDB supports dual PCI interfaces configurable as either two independent 32-bit buses or one 64-bit bus, with PCI1 capable of agent mode and both interfaces supporting host bridge functionality. Section 13 of the MPC8349EA Hardware Specifications confirms PCI Specification Revision 2.3 compliance, programmable coherency, and address translation - enabling flexible system topology design.

What is the recommended power sequencing for the MPC8349CZUAJDB?

The MPC8349CZUAJDB requires core supply (VDD/AVDD) to reach 90% of nominal value before I/O supplies (GVDD/LVDD/OVDD) rise above 0.7 V, and PORESET must be asserted before power ramp-up completes. This prevents I/O contention and excessive current draw (3–5 A), as specified in Section 2.2.1 of the MPC8349EA Hardware Specifications Rev. 13.
