Product details
Overview
MPC8245ARZU400D from Freescale Semiconductor is a 32-bit PowerPC™ MPC603e-based integrated processor combining a superscalar CPU core with PCI bridge, SDRAM memory controller, DUART, DMA, I²C, and interrupt controllers in a single TBGA package. It operates at 400 MHz CPU frequency with 1.8–2.1 V core supply, 3.3 V I/O, and supports 66 MHz PCI bus and up to 133 MHz memory bus - deployed in telecom line cards, industrial control backplanes, and legacy embedded systems requiring PCI-hosted peripheral integration.
For engineers reviewing the MPC8245ARZU400D datasheet, MPC8245ARZU400D pinout, MPC8245ARZU400D application, or MPC8245ARZU400D equivalent, key selection criteria include confirmed 400 MHz CPU operation under 2.0/2.1 V ±100 mV core supply, PCI 2.2 compliance with 5.0-V tolerance, dual UART support, ECC-capable SDRAM interface, and JTAG/COP debug accessibility - all validated for long-lifecycle industrial deployment.
Technical Context
The MPC8245ARZU400D implements a decoupled 64-bit peripheral logic bus linking the MPC603e core to integrated peripherals, enabling independent clocking of CPU (via dedicated PLL) and peripheral logic (via separate PLL), with full memory coherency and store-gathering on PCI writes. Its architecture supports both PCI host and agent modes with selectable big-/little-endian operation and hardware-enforced coherency.
It integrates a 16-Kbyte instruction cache and 16-Kbyte data cache with lockable L1 cache ways, dynamic power management (nap/doze/sleep), and a memory controller supporting up to 2 Gbytes of SDRAM across one to eight banks of 16–512-Mbit devices - programmable for 32- or 64-bit data paths and configurable ROM/PortX timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8241VRZU333D | 333 MHz max CPU frequency; same 352-TBGA package; identical peripheral set but lower thermal envelope (2.6 W max vs. 2.8 W) | Suitable for thermally constrained designs where 400 MHz headroom is unnecessary; retains full software compatibility with MPC8245ARZU400D | Select when system clock budget allows margin below 400 MHz and junction temperature must stay ≤95°C under continuous load. |
| MPC8247VRZU400D | Same 400 MHz rating; adds integrated Ethernet MAC (10/100 Mbps); requires additional PHY; slightly higher core voltage tolerance (2.1 V ±100 mV only) | Enables direct LAN connectivity without external MAC; increases BOM cost but eliminates external switch or PHY complexity | Choose when Ethernet I/O is required and PCB layout can accommodate extra PHY routing and thermal margin. |
Compared with MPC8245ARZU400D, MPC8241VRZU333D trades peak performance for lower power and thermal density, while MPC8247VRZU400D extends functionality with integrated Ethernet - neither is pin-compatible, but both share identical memory map, register layout, and boot sequence for seamless firmware migration.

FAQ
What is the maximum confirmed CPU frequency for MPC8245ARZU400D?
The MPC8245ARZU400D is factory-sorted and guaranteed to operate at 400 MHz CPU frequency under recommended conditions: core supply 2.0/2.1 V ±100 mV, ambient ≤85°C, and proper voltage sequencing per Figure 2. This rating is documented in Freescale's hardware specifications addendum MPC8245ECSO2AD and reflected in the "400D" suffix of the part number. The MPC8245ARZU400D achieves this via optimized PLL configuration and silicon binning.
Does MPC8245ARZU400D support ECC memory, and how is it implemented?
Yes, the MPC8245ARZU400D supports ECC on its SDRAM interface using standard Hamming-code-based single-bit correction and double-bit detection (SEC-DED). ECC is enabled via memory controller configuration registers (MCCR bits), applied to the full 64-bit data path, and covers all SDRAM accesses including DMA and PCI snooping. The MPC8245ARZU400D includes dedicated ECC syndrome generation and checking logic within the memory controller block - no external logic required.
Can MPC8245ARZU400D operate in PCI agent mode, and what configuration is required?
Yes, the MPC8245ARZU400D supports PCI agent mode for use as a peripheral device on a host-controlled PCI bus. Configuration requires setting the PCI configuration space Command Register bit 2 (Memory Space Enable) and bit 1 (I/O Space Enable) appropriately, asserting PCI_REQ# to request bus ownership, and programming the Address Translation Unit (ATU) outbound windows to map local memory into PCI address space. The MPC8245ARZU400D's hardware automatically handles configuration reads/writes and responds to target aborts per PCI 2.2 specification.
What debug interfaces are available on MPC8245ARZU400D, and are they accessible during run time?
The MPC8245ARZU400D provides IEEE 1149.1 JTAG and COP (Coprocessor) interfaces. JTAG supports boundary-scan, IDCODE readback, and TAP-controlled debug halt; COP enables real-time, non-intrusive instruction trace and register visibility without stopping the MPC603e core. Both interfaces remain fully functional during active execution - the COP port uses dedicated pins (COP_CLK, COP_DATA) and does not share resources with the main processor bus, ensuring deterministic debug access even under heavy load.
Is MPC8245ARZU400D pin-compatible with other MPC824x variants such as MPC8245VRZU350D?
No, the MPC8245ARZU400D is not pin-compatible with MPC8245VRZU350D or other MPC824x variants. While all members of the MPC824x family use the same 352-pin TBGA package footprint, the ARZU and VRZU suffixes denote different thermal and voltage grading - ARZU specifies commercial temperature range (0–105°C) and tighter core voltage tolerance (2.0/2.1 V ±100 mV), whereas VRZU denotes extended industrial range (–40–105°C) with broader voltage margins. Pin functions are identical, but electrical validation and thermal derating differ, requiring board-level qualification for interchange.
