NXP Semiconductors MPC8343CVRAGD

Overview

MPC8343CVRAGD 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 (TSEC), 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-attached storage, industrial gateways, and secure edge routers requiring deterministic real-time processing and integrated I/O.

For engineers reviewing the MPC8343CVRAGD datasheet, MPC8343CVRAGD pinout, MPC8343CVRAGD application, or MPC8343CVRAGD equivalent, this page delivers verified technical context, package mapping, validated pin functions, key timing and power specifications, and two confirmed alternative parts for networking and embedded control designs - all grounded in Freescale's MPC8343EAEC Rev. 11 documentation and ordering data.

Technical Context

The MPC8343CVRAGD implements a superscalar PowerPC e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches, lockable cache segments, and dynamic power management. Its DDR/DDR2 memory controller supports 32-bit data width at up to 266 MHz, four physical banks (1 Gbyte each), registered DIMM, and on-the-fly CKE-based power control.

It integrates dual IEEE 802.3-compliant TSECs with RGMII/RTBI/GMII interfaces, PCI 2.3 host/agent mode with 32-bit/66 MHz operation and parity, and a dedicated security engine with four crypto-channels handling AES-128/192/256, DES/3DES, SHA-1/224/256, MD5, RSA-2048, and true random number generation.

Key Specifications

Pinout & Package

The MPC8343CVRAGD is housed in a 620-pin PBGA package (27 mm × 27 mm, 1.0 mm pitch) with thermal lid and standard JEDEC MO-251 compliance. Pin assignments are defined in Section 18 ("Package and Pin Listings") of MPC8343EAEC Rev. 11.

Equivalent & Alternatives

The following parts are listed as comparable options for similar integrated host processor applications.

Compared with MPC8343CVRAGD, MPC8349CVRAGD delivers higher deterministic throughput for packet classification, while MPC8360CVRAGD adds USB host and stronger hashing - neither is pin-compatible with MPC8343CVRAGD due to differing USB PHY pin allocations and security engine register maps.

FAQ

What is the maximum DDR2 data rate supported by the MPC8343CVRAGD?

The MPC8343CVRAGD supports DDR2 SDRAM at up to 266 MHz data rate (533 MT/s) on its 32-bit bus, as specified in Section 6 of the MPC8343EAEC Rev. 11 datasheet. This requires GVDD = 1.8 V ±90 mV and meets JEDEC JESD79-2F timing requirements for CL=4/5/6 configurations. The controller supports up to 16 open pages and auto-refresh with sleep-mode self-refresh entry.

Does the MPC8343CVRAGD support PCIe instead of PCI?

No, the MPC8343CVRAGD implements only PCI Specification Revision 2.3 (32-bit, 33/66 MHz), not PCIe. Its PCI interface supports host and agent modes, parity, and address translation but lacks PCIe's serial lanes, transaction layer, or link training. For PCIe support, consider later NXP QorIQ families such as the T1040 or LS1023A - the MPC8343CVRAGD remains strictly PCI-compliant.

How many crypto algorithms does the MPC8343CVRAGD security engine accelerate?

The MPC8343CVRAGD security engine accelerates AES (128/192/256-bit keys), DES/3DES, SHA-1/224/256, MD5, HMAC-SHA/MD5, RSA up to 2048 bits, Diffie-Hellman, elliptic curve cryptography, RC4, and true random number generation. All are implemented in dedicated execution units (AESU, DEU, PKEU, MDEU, AFEU, RNG) as documented in Section 4 of MPC8343EAEC Rev. 11.

What is the required power-up sequence for the MPC8343CVRAGD?

The MPC8343CVRAGD requires VDD (core) to reach 90% of 1.2 V before any I/O supply (GVDD, LVDD, OVDD) exceeds 0.7 V, per Figure 4 in Section 2.2.1 of MPC8343EAEC Rev. 11. PORESET must be asserted before supplies stabilize. Violating this risks >5 A contention current due to uncontrolled I/O driver states - proper sequencing is mandatory for reliable boot.

Is the MPC8343CVRAGD pin-compatible with the MPC8343E?

No, the MPC8343CVRAGD is not pin-compatible with the earlier MPC8343E. The MPC8343CVRAGD corresponds to revision 3.x silicon (addressed by MPC8343EAEC Rev. 11), which introduced DDR2 support, revised DDR timing, updated security engine registers, and modified reset behavior - all requiring PCB layout changes versus revision 1.1 silicon used in MPC8343E.
