NXP Semiconductors MPC8536EAVTANGA

Overview

MPC8536EAVTANGA from NXP Semiconductors (formerly Freescale) is a high-performance PowerQUICC III integrated communications processor built around a 32-bit e500 core operating up to 1.5 GHz, featuring 32-KB L1 instruction and data caches, 512-KB 8-way set-associative L2 cache, DDR2/DDR3 SDRAM controller with full ECC support, and dual enhanced three-speed Ethernet controllers (eTSECs) compliant with IEEE 802.3, 802.3u, 802.3z, and IEEE 1588. It targets network edge routing, industrial gateways, and secure communications infrastructure.

For engineers reviewing the MPC8536EAVTANGA datasheet, MPC8536EAVTANGA pinout, MPC8536EAVTANGA application, or MPC8536EAVTANGA equivalent, key selection considerations include its 783-pin FC-PBGA package, triple PCI Express 1.0a interfaces, integrated security engine (SEC) for IPsec/IKE/SSL/TLS acceleration, IEEE 1588 timestamping capability, and hardware TCP/IP offload in the eTSECs.

Technical Context

The MPC8536EAVTANGA implements the Power Architecture® technology with a superscalar, dual-issue e500 core supporting 36-bit physical addressing and embedded double-precision floating-point APU. Its memory subsystem includes tightly coupled L1 caches and a unified 512-KB L2 cache with ECC protection on tag and data paths.

It integrates a DDR2/DDR3 SDRAM controller supporting 64-bit/32-bit buses at up to 333 MHz (667 MT/s), full ECC (single-bit correction, double-bit detection), and dynamic MCKE assertion for low-power sleep mode. The dual eTSECs provide hardware-accelerated TCP/IP checksum, QoS, RMON statistics, ARP parsing, and deep-sleep packet buffering with wake-on-LAN.

Key Specifications

Pinout & Package

Equivalent & Alternatives

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

Compared with MPC8548CVMAGDB, MPC8536EAVTANGA offers higher clock frequency (1.5 GHz vs. 1.33 GHz), triple PCIe lanes, and integrated SATA - making it superior for storage-integrated gateways. Compared with LS1023A-CACZAA, it provides deterministic Power Architecture real-time performance and mature VxWorks/uClinux BSPs, but lacks DDR4 and modern virtualization features.

FAQ

What is the maximum DDR3 data rate supported by the MPC8536EAVTANGA?

The MPC8536EAVTANGA supports DDR3 SDRAM at up to 333 MHz clock frequency, delivering an effective data rate of 667 MT/s on its 64-bit bus. This is confirmed in Section 2.6 of the MPC8536EEC Rev. 7 datasheet, which specifies timing parameters for DDR3-667 operation with full ECC and on-die termination control. The MPC8536EAVTANGA maintains signal integrity at this rate through calibrated MDQS strobes and per-byte data masks (MDM[0:8]).

Does the MPC8536EAVTANGA support IEEE 1588 Precision Time Protocol in hardware?

Yes, the MPC8536EAVTANGA includes dedicated IEEE 1588 hardware timestamping logic in both eTSEC controllers. It supports timestamp generation on transmit/receive events, programmable trigger inputs/outputs (TSEC_1588_TRIG_IN[0:1], TSEC_1588_TRIG_OUT[0:1]), and pulse output generation (TSEC_1588_PULSE_OUT1/2). This enables sub-microsecond accuracy without CPU intervention - a confirmed capability documented in Sections 2.9 and 3.11 of the MPC8536EEC datasheet.

How many PCI Express lanes does the MPC8536EAVTANGA provide, and what configurations are supported?

The MPC8536EAVTANGA integrates three PCI Express 1.0a root complex interfaces, configurable as one x8/x4/x2/x1 port plus two x4/x2/x1 ports, or one x4/x2/x1 port plus two x2/x1 ports. This flexibility is explicitly defined in the "High-speed interfaces" section of the datasheet and validated in the pinout listing (Table 1), where PCIe differential pairs are assigned to dedicated SerDes lanes. The MPC8536EAVTANGA does not support PCIe 2.0 or higher generations.

What security algorithms are accelerated by the integrated Security Engine (SEC) in the MPC8536EAVTANGA?

The MPC8536EAVTANGA's integrated Security Engine (SEC) accelerates symmetric ciphers (AES, DES, 3DES), hash functions (SHA-1, SHA-256), public-key operations (RSA, Diffie-Hellman, elliptic curve cryptography), and protocols including IPsec, IKE, SSL/TLS, iSCSI, SRTP, and IEEE 802.16e. These capabilities are listed in the datasheet's "Integrated security engine" bullet and verified in the SEC functional description (Section 2.22), confirming hardware offload for all major cryptographic primitives used in enterprise and carrier security stacks.

Is the MPC8536EAVTANGA pin-compatible with other PowerQUICC III processors like the MPC8548?

No, the MPC8536EAVTANGA is not pin-compatible with the MPC8548 despite sharing the same 783-pin FC-PBGA package footprint. Pin assignments differ significantly - for example, MPC8536EAVTANGA dedicates pins to SATA controllers and triple PCIe, while MPC8548 allocates those balls to additional local bus signals and different SerDes mappings. Table 1 of the MPC8536EEC datasheet confirms unique signal-to-ball mapping, and Freescale's ordering nomenclature (e.g., "AVTANGA" suffix) denotes distinct package and configuration variants.
