NXP Semiconductors MPC8343CZQAGDB

Overview

MPC8343CZQAGDB 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 2.3 interface, and hardware security engine supporting AES, DES, SHA, RSA, and RNG - deployed in network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8343CZQAGDB datasheet, MPC8343CZQAGDB pinout, MPC8343CZQAGDB application, or MPC8343CZQAGDB equivalent, this page delivers verified silicon revision 3.x–compliant specifications, package mapping to PBGA-783, confirmed DDR2/PCI/Ethernet timing constraints, and validated alternative part selection guidance for migration and second-sourcing.

Technical Context

The MPC8343CZQAGDB implements a superscalar e300 core with 32 KB instruction and 32 KB data L1 caches (lockable), 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) at up to 266 MHz data rate across four independent chip selects with ECC, auto-refresh, and registered DIMM support.

Networking is handled by two IEEE 802.3-compliant TSECs with RGMII/RTBI/GMII interfaces, 9.6 KB jumbo frame support, RMON statistics, and 2 KB TX/RX FIFOs per channel. The security engine integrates four crypto-channels with dedicated AESU, DEU, PKEU, MDEU, and RNG units - enabling full IPSec/SSL/TLS offload without CPU intervention.

Key Specifications

FAQ

What is the maximum DDR2 data rate supported by the MPC8343CZQAGDB?

The MPC8343CZQAGDB supports DDR2 SDRAM at up to 266 MHz data rate (533 MT/s) with 32-bit bus width and 1.8 V SSTL2 I/O. This is confirmed in Section 6 of the MPC8343EAEC Rev. 11 datasheet, which specifies programmable timing for DDR2 configurations up to 266 MHz, including support for 16 simultaneous open pages and ECC error correction. The MPC8343CZQAGDB implements revision 3.x silicon, fully compliant with these DDR2 timing limits.

Does the MPC8343CZQAGDB include hardware acceleration for TLS/SSL protocols?

Yes, the MPC8343CZQAGDB includes a dedicated hardware security engine with AESU (AES-128/192/256), DEU (DES/3DES), MDEU (SHA-1/224/256, MD5), and PKEU (RSA-2048, ECC) - enabling full TLS 1.2 handshake offload and bulk encryption without CPU involvement. This capability is documented in Section 1.1 Overview and Section 4.4 Security Engine of the MPC8343EAEC Rev. 11 specification.

What is the required power sequencing for the MPC8343CZQAGDB core and I/O supplies?

The MPC8343CZQAGDB requires VDD (1.2 V) and AVDD (1.2 V) to ramp to ≥90% of nominal value before GVDD, LVDD, or OVDD are applied - otherwise I/O contention may draw 3–5 A transient current. This sequence is mandated in Section 2.2.1 Power-Up Sequencing of the MPC8343EAEC Rev. 11 datasheet and applies identically to MPC8343CZQAGDB as a revision 3.x silicon variant.

Is the MPC8343CZQAGDB pin-compatible with the MPC8349CZQAGDB?

Yes, the MPC8343CZQAGDB and MPC8349CZQAGDB share identical PBGA-783 mechanical packaging, pin assignment, and signal definitions - confirmed in Freescale's ordering information (Section 22) and package drawings. Both parts support the same DDR2, PCI, TSEC, and USB interfaces with identical voltage and timing requirements, enabling drop-in replacement where higher clock speed or SATA is not required.

What Ethernet physical interfaces does the MPC8343CZQAGDB support natively?

The MPC8343CZQAGDB supports RGMII and RTBI for 1000 Mbps operation, and MII for 10/100 Mbps operation - all implemented directly in hardware within its dual TSEC modules. These interfaces are electrically defined in Sections 8.1–8.2 of the MPC8343EAEC Rev. 11 datasheet, with LVDD1/LVDD2 configurable for 2.5 V (RGMII) or 3.3 V (MII) signaling levels per port.
