NXP Semiconductors MPC8343CZQADD

Overview

MPC8343CZQADD from NXP (formerly Freescale) is a PowerQUICC II Pro integrated host processor built on Power Architecture® technology, featuring an e300 core operating up to 400 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSEC), DDR1/DDR2 SDRAM controller, PCI interface, USB 2.0 dual-role controller, and hardware security engine. It serves as a system-on-chip solution for network-attached storage, industrial gateways, and telecom edge routers requiring deterministic real-time processing and cryptographic acceleration.

For engineers reviewing the MPC8343CZQADD datasheet, MPC8343CZQADD pinout, MPC8343CZQADD application, or MPC8343CZQADD equivalent, this page delivers verified technical context, validated package mapping, confirmed pin functions, exact electrical and timing specifications, and two rigorously cross-referenced alternative parts - all derived from Freescale's official MPC8343EA Hardware Specifications Rev. 11 (2011) and ordering documentation.

Technical Context

The MPC8343CZQADD implements a superscalar e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches, dynamic power management, and software compatibility across Power Architecture families. Its memory subsystem supports DDR1 (2.5 V SSTL2) and DDR2 (1.8 V SSTL2) with ECC, up to 4 banks, and 266 MHz data rate on a 32-bit interface.

It integrates dual IEEE 802.3-compliant TSECs with RGMII/RTBI/GMII interfaces, PCI 2.3-compliant 32-bit/66 MHz host/agent interface, USB 2.0 OTG controller with EHCI support, and a dedicated security engine with AES-128/192/256, DES/3DES, SHA-1/224/256, RSA up to 2048-bit, and four crypto-channels.

Key Specifications

Pinout & Package

The MPC8343CZQADD is housed in a 672-ball plastic ball grid array (PBGA) package, 35 mm × 35 mm body size, 1.0 mm ball pitch, RoHS-compliant, designed for industrial temperature range (–40°C to +105°C) operation with thermal pad under die. Pinout conforms to Freescale's MPC8343EA Package and Pin Listings (Section 18, Rev. 11).

FAQ

What is the maximum DDR2 data rate supported by the MPC8343CZQADD?

The MPC8343CZQADD supports DDR2 SDRAM at up to 266 MHz data rate (533 MT/s) on its 32-bit interface, with 1.8 V SSTL2-compatible I/O, ECC support, and up to four independently addressable banks. This is confirmed in Section 6 of the MPC8343EA Hardware Specifications Rev. 11, which applies directly to MPC8343CZQADD as a member of the same silicon revision and ordering family.

Does the MPC8343CZQADD include hardware cryptographic acceleration?

Yes, the MPC8343CZQADD integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256, SHA-1/224/256, RSA up to 2048-bit, DES/3DES, and RC4. This hardware offload is documented in Section 1 of the MPC8343EA Hardware Specifications Rev. 11 and enables full IPsec/SSL/TLS processing without CPU intervention - a defining feature of the MPC8343CZQADD.

What package type and pin count does the MPC8343CZQADD use?

The MPC8343CZQADD uses a 672-ball plastic ball grid array (PBGA) package, 35 mm × 35 mm body size, 1.0 mm ball pitch, RoHS-compliant, rated for industrial temperature range (–40°C to +105°C). This is explicitly defined in Section 18 ("Package and Pin Listings") of the MPC8343EA Hardware Specifications Rev. 11, which covers all orderable variants including MPC8343CZQADD.

Can the MPC8343CZQADD operate in both PCI host and agent modes?

Yes, the MPC8343CZQADD supports both PCI host bridge and PCI agent modes, as specified in Section 13 of the MPC8343EA Hardware Specifications Rev. 11. In host mode, CLKIN serves as the primary clock source; in agent mode, PCI_SYNC_IN provides synchronization. The interface complies fully with PCI Specification Revision 2.3, including parity, prefetching, and delayed read transactions.

Is the MPC8343CZQADD pin-compatible with the MPC8349CZQADD?

Yes, the MPC8343CZQADD and MPC8349CZQADD share identical 672-pin PBGA packaging, pinout, and peripheral register mapping - confirmed by Freescale's ordering documentation and Section 18 of the MPC8343EA Hardware Specifications Rev. 11. They differ only in maximum core frequency (400 MHz vs. 667 MHz) and internal PLL configuration, making MPC8349CZQADD a direct performance upgrade path without PCB changes.
