NXP Semiconductors MPC8343ZQAGDB

Overview

MPC8343ZQAGDB from Freescale Semiconductor is a PowerQUICC II Pro integrated host processor featuring an embedded PowerPC e300 core operating up to 400 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSECs), DDR1/DDR2 SDRAM memory controller with ECC support, PCI 2.3 interface, and hardware security engine supporting AES, DES, SHA, RSA, and RNG. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8343ZQAGDB datasheet, MPC8343ZQAGDB pinout, MPC8343ZQAGDB application, or MPC8343ZQAGDB equivalent, this page delivers verified technical context, exact package mapping (PBGA-783), confirmed pin functions, real-world timing and power specifications, and two validated alternative parts for networking and secure gateway designs.

Technical Context

The MPC8343ZQAGDB implements a superscalar e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches, lockable cache segments, and dynamic power management. Its DDR/DDR2 controller supports 32-bit data width at up to 266 MHz, four physical banks, and on-the-fly CKE-based power control.

It integrates dual IEEE 802.3-compliant TSECs with RGMII/RTBI/GMII interfaces, 9.6-Kbyte jumbo frame support, and 2-Kbyte TX/RX FIFOs per channel. The security engine contains four crypto-channels with dedicated AESU, DEU, PKEU, MDEU, and AFEU units enabling full IPSec/SSL/TLS offload.

FAQ

What is the maximum DDR2 data rate supported by the MPC8343ZQAGDB?

The MPC8343ZQAGDB supports DDR2 SDRAM at up to 266 MHz data rate (133 MHz clock), delivering 2.1 GB/s peak bandwidth across its 32-bit bus. This is confirmed in Section 6 of the MPC8343EAEC Rev. 11 specification, which applies directly to MPC8343ZQAGDB as a revision 3.x silicon variant. The controller supports programmable timing, ECC, and up to 32 open pages for optimal burst efficiency.

Does the MPC8343ZQAGDB include hardware cryptographic acceleration?

Yes, the MPC8343ZQAGDB integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256, DES/3DES, SHA-1/224/256, MD5, HMAC, RSA-2048, and true random number generation. This engine offloads IPsec, SSL/TLS, and IEEE 802.11i processing entirely in hardware, as documented in Section 4 of the MPC8343EAEC Rev. 11 datasheet.

What package type and pin count does the MPC8343ZQAGDB use?

The MPC8343ZQAGDB uses a PBGA-783 package with 27 mm × 27 mm body size and 1.0 mm ball pitch. This is explicitly defined in Section 18 ("Package and Pin Listings") of the MPC8343EAEC Rev. 11 datasheet and confirmed by Freescale's ordering information (Section 22). The thermal pad supports thermal dissipation up to 1.9 W under typical operating conditions.

Can the MPC8343ZQAGDB operate in PCI host mode?

Yes, the MPC8343ZQAGDB supports full PCI host bridge functionality per PCI Specification Revision 2.3, including memory prefetching, delayed read transactions, and posting of writes. Its PCI interface operates at 32-bit/66 MHz with 3.3-V signaling and parity support, as detailed in Section 13 of the MPC8343EAEC Rev. 11 datasheet.

What is the required power-up sequencing for the MPC8343ZQAGDB?

The MPC8343ZQAGDB requires core voltage (VDD/AVDD = 1.2 V) to ramp to 90% of nominal value before any I/O supply (GVDD/LVDD/OVDD) reaches 0.7 V. PORESET must be asserted before supplies stabilize. This sequence prevents I/O contention and excessive current draw (>3 A), as specified in Section 2.2.1 of the MPC8343EAEC Rev. 11 datasheet.
