For engineers reviewing the MPC8548EVUAUJ datasheet, MPC8548EVUAUJ pinout, MPC8548EVUAUJ application, or MPC8548EVUAUJ equivalent, key selection considerations include its 1.0 GHz e500 core frequency, 64-bit DDR2 interface with ECC, quad 10/100/1000-Mbps eTSEC support, SEC crypto acceleration, and configurable high-speed I/O multiplexing between PCI Express and RapidIO.

Technical Context

The MPC8548EVUAUJ implements the e500v2 core with 32-Kbyte L1 instruction and data caches (parity-protected), 36-bit real addressing, and MMU supporting 4-Kbyte to 4-Gbyte page sizes. Its L2 cache/SRAM is eight-way set-associative (32-byte lines), configurable for cache or SRAM mode, with full ECC on 64-bit boundaries and programmable line locking.

It features an integrated DDR2/DDR SDRAM controller with 64-bit data bus, four banks (up to 16 Gbytes total), on-die termination for DDR2, auto-refresh, and sleep-mode self-refresh support. The security engine includes four crypto-channels, PKEU (RSA/DH up to 2048 bits), AESU (128/192/256-bit keys), MDEU (SHA-1/SHA-256, MD5), and RNG.

FAQ

What is the maximum operating frequency of the MPC8548EVUAUJ core?

The MPC8548EVUAUJ features an e500v2 core rated for a maximum frequency of 1.0 GHz under industrial temperature conditions (junction temperature ≤ 105°C). This frequency is achieved with 1.1 V ± 55 mV core supply and proper thermal management. Performance scales linearly with clock speed, and the device supports dynamic frequency scaling via doze/nap/sleep power states to reduce active power consumption during idle periods. The MPC8548EVUAUJ maintains full functionality-including L2 cache, DDR2 controller, and eTSEC offload-at this rated frequency.

Does the MPC8548EVUAUJ support DDR2 memory with ECC?

Yes, the MPC8548EVUAUJ DDR2/DDR memory controller fully supports ECC on the 64-bit data bus. ECC protection covers both data and check bits across all memory transactions, with error detection and correction handled transparently in hardware. The controller supports single-bit error correction and double-bit error detection (SEC-DED) for DDR2 SDRAM operating at 1.8 V, and is compatible with standard DDR2 SO-DIMMs and registered modules. ECC is enabled via configuration registers and does not require external logic or additional memory chips.

How many Ethernet controllers does the MPC8548EVUAUJ integrate, and what speeds do they support?

The MPC8548EVUAUJ integrates four independent enhanced Three-Speed Ethernet Controllers (eTSECs), each supporting 10/100/1000 Mbps full- and half-duplex operation. Each eTSEC supports multiple physical layer interfaces including MII, RMII, GMII, TBI, RTBI, and RGMII, allowing flexible PHY selection. Hardware offload includes TCP/IP checksum generation/verification, VLAN insertion/deletion, jumbo frames up to 9.6 KB, and eight-priority transmit/receive queues per port - all implemented without CPU involvement. This enables the MPC8548EVUAUJ to sustain full line-rate throughput across all four ports simultaneously.

What cryptographic algorithms are accelerated by the MPC8548EVUAUJ Security Engine (SEC)?

The MPC8548EVUAUJ Security Engine (SEC) accelerates AES (128/192/256-bit keys in ECB/CBC/CTR/CCM modes), DES/3DES (ECB/CBC), SHA-1/SHA-256, MD5, HMAC, RSA up to 2048 bits (PKEU), elliptic curve cryptography (F2m/Fp, up to 511 bits), and Kasumi (F8/F9). These functions are executed in dedicated hardware units - AESU, DEU, MDEU, PKEU, KEU - enabling concurrent processing of multiple crypto operations. The SEC supports IPSec, SSL/TLS, WTLS, and 3GPP protocol stacks with zero-copy DMA and descriptor chaining, delivering >200 Mbps encrypted throughput without burdening the e500 core.

What package type and thermal specifications apply to the MPC8548EVUAUJ?

The MPC8548EVUAUJ is packaged in a 783-ball Fine-Pitch Ball Grid Array (FC-PBGA) measuring 27 mm × 27 mm with 1.0 mm ball pitch. It is rated for industrial temperature operation with a junction temperature range of 0°C to +105°C. Thermal design requires a minimum 4-layer PCB with dedicated ground/power planes, thermal vias under the package, and a heatsink capable of dissipating up to 18.6 W (maximum smoke-test condition). The package supports lead-free assembly and complies with RoHS Directive 2011/65/EU. Thermal resistance (θJA) is 12.5°C/W typical under standard JEDEC test conditions.
