NXP Semiconductors MPC8541EVTAQF

Overview

MPC8541EVTAQF from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ III integrated communications processor featuring an e500 core, dual 10/100/1000 Ethernet controllers (TSECs), DDR SDRAM controller, PCI interface, security engine with AES/DES/SHA/RSA acceleration, and CPM-based FCCs - deployed in carrier-grade routers, wireless baseband units, and secure gateways operating at up to 1 GHz core frequency.

For engineers reviewing the MPC8541EVTAQF datasheet, MPC8541EVTAQF pinout, MPC8541EVTAQF application, or MPC8541EVTAQF equivalent, this page delivers verified electrical specs (1.2 V core, 2.5 V DDR I/O, 3.3 V PCI/LB), thermal limits (Tj ≤ 105°C), clock timing (SYSCLK ≤ 166 MHz), security engine capabilities (4 crypto-channels, 2048-bit RSA), and package mapping (783-pin FC-PBGA).

Technical Context

The MPC8541EVTAQF implements a dual-issue, superscalar e500 Book E-compatible core with 32 KB L1 instruction and 32 KB L1 data caches (parity-protected), plus 256 KB on-chip memory configurable as L2 cache or SRAM with full ECC. Its OCeaN switch fabric provides three-port packet switching with priority-based reordering and starvation avoidance for internal traffic between TSECs, CPM, and DDR.

It integrates two independent TSECs supporting GMII/MII/TBI/RGMII/RTBI interfaces, a 64-bit DDR SDRAM controller (2.5 V SSTL2, 4 banks × 1 Gbyte), dual 32-bit or single 64-bit PCI 2.2 ports, and a programmable interrupt controller compliant with OpenPIC architecture - all coordinated via a coherency-enabled Core Complex and system-level ATMU for address translation across local, PCI, and DDR domains.

Key Specifications

Pinout & Package

783-pin FC-PBGA (27 mm × 27 mm, 1.0 mm ball pitch), RoHS-compliant, thermal pad exposed on underside. Pinout defined in Section 14 "Package and Pin Listings" of MPC8541E Hardware Specification Rev. 4.2.

Equivalent & Alternatives

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

Compared with MPC8541EVTAQF, MPC8548EVTAGD offers higher clock rate and expanded I/O but demands revised thermal and layout design, while P1022NSE replaces CPM with modern SerDes and drops legacy protocol engines - making MPC8541EVTAQF irreplaceable where FCC-based T1/E1 or HDLC is mandatory.

FAQ

What is the maximum supported DDR SDRAM data rate for MPC8541EVTAQF?

The MPC8541EVTAQF DDR SDRAM controller supports first-generation DDR SDRAM up to DDR-333 (333 MHz data rate), with 64-bit bus width, four banks, and full ECC protection. It operates at 2.5 V SSTL2 levels and supports registered DIMMs. The controller is not compatible with DDR2 or DDR3 memory technologies.

Does MPC8541EVTAQF support PCI Express?

No, MPC8541EVTAQF does not support PCI Express. It implements PCI 2.2 compliance with one 64-bit or two 32-bit parallel PCI buses operating at 16–66 MHz. The device lacks PCIe PHY, root complex logic, or link training capabilities - those features appear only in later NXP QorIQ families such as P1/P2 series.

What boot sources are supported by MPC8541EVTAQF?

MPC8541EVTAQF supports boot from serial ROM via its standalone I2C interface, with optional extended addressing and CRC-protected preamble validation. It also supports boot from local bus devices (e.g., NOR flash on CS0) and JTAG-based debug boot. The boot sequencer initializes configuration registers and memory prior to e500 core execution.

Is MPC8541EVTAQF pin-compatible with other PowerQUICC III processors like MPC8555E?

No, MPC8541EVTAQF is not pin-compatible with MPC8555E. Although both belong to the PowerQUICC III family and share architectural similarities, they differ in pin count (783 vs. 1296), package type (FC-PBGA vs. PBGA), I/O voltage assignments, and peripheral integration - requiring unique PCB layouts and power delivery networks for each device.

What is the thermal design power (TDP) of MPC8541EVTAQF at 1 GHz operation?

At 1 GHz operation with VDD = 1.3 V, the MPC8541EVTAQF has a maximum power dissipation of 12.2 W (excluding I/O supply power). This value assumes worst-case process corner, junction temperature of 105°C, and artificial smoke test conditions. System-level thermal design must account for additional I/O power (e.g., 0.73 W DDR, 0.14 W PCI) and board-level convection constraints.
