MPC8548PXAUJC557 - PowerQUICC III 1.333GHz e500 MPU | NXP
部品番号: MPC8548PXAUJC557 ✓ 生産中MPC8548PXAUJC557 概要
A microprocessor (MPU) is a single-chip CPU that integrates the arithmetic logic unit, control unit, registers, cache, and often on-chip peripherals into one silicon die. MPU architecture follows the von Neumann or Harvard model and sits at the top of the embedded processing hierarchy: microcontroller -> microprocessor -> SoC high-end systems. The e500 core is a Power Book E embedded implementation, optimized for deterministic interrupt response and low-latency networking.
Key features of the MPC8548PXAUJC557 include the e500 core with integrated L1/L2 caches, a 64-bit DDR2 memory controller, dual x1/x2/x4/x8 PCI Express controllers, multiple Gigabit Ethernet MACs, RapidIO interconnect, and an integrated security engine. The 783-ball FCPBGA package provides the high pin density required for parallel memory, multiple high-speed serial links, and extensive general-purpose I/O.
The architecture combines the e500 superscalar core with a coherent core complex bus and a high-bandwidth system bus that feeds the platform peripherals. An integrated security block accelerates IPSec, SSL/TLS, and bulk data encryption, while dedicated DMA engines offload packet movement from the core.
Typical applications include enterprise routers and switches, secure VPN gateways, industrial control and automation platforms, line cards for multi-service switches, and telecom base station controllers. The wide peripheral mix and security acceleration make it especially attractive for L2/L3 managed switches and edge routers.
A key design consideration for the 783-FCPBGA is PCB layout: the package demands a high-layer-count board (typically 8 or more layers) with controlled-impedance routing for DDR2, SERDES, and PCI Express signals, plus a solid thermal via array beneath the exposed die region.
This page synthesizes verified distributor pricing, same-family drop-in alternatives, and PCB-layout considerations that go beyond the manufacturer datasheet, helping hardware engineers accelerate design-in and qualification for the MPC8548PXAUJC557.

主な用途
MPC8548PXAUJC557 の用途: 6 件s: Enterprise Routers and L3 Switches, Secure VPN Gateway Appliances, Industrial Automation Controllers, Telecom Base Station Controllers, Network Attached Storage Controllers, Line Cards for Multi-Service Switches.
Enterprise Routers and L3 Switches
The MPC8548PXAUJC557's 1.333 GHz e500 core delivers deterministic packet-processing throughput needed for enterprise routers and managed L3 switches. The integrated security engine accelerates IPSec and SSL/TLS handshake rates, while dual PCI Express controllers provide high-bandwidth uplinks to switch fabric ASICs. Placed as the main CPU on the routing engine card, the device handles routing-table lookups, ACL enforcement, and management-plane services; it dissipates significant power at full load, so a top-mounted heatsink with thermal vias is essential.
おすすめ
Secure VPN Gateway Appliances
The MPC8548PXAUJC557's on-chip security engine accelerates bulk IPSec AES/3DES and SSL/TLS RSA operations, offloading the e500 core from data-path encryption. This makes it ideal for branch-office VPN gateways and SSL VPN concentrators that must sustain hundreds of tunnels. Multiple integrated Gigabit Ethernet MACs provide direct WAN/LAN connectivity without an external PHY switch. Trade-off: at high tunnel counts, two e500 cores (MPC8572E) may be required to maintain wire-speed throughput.
おすすめ
Industrial Automation Controllers
In factory automation and process-control platforms, the MPC8548PXAUJC557's deterministic e500 core, RapidIO interconnect, and PCI Express expansion deliver real-time control plus high-bandwidth data acquisition. Engineers use it in PLC backplanes, motion controllers, and SCADA concentrators where deterministic interrupt latency matters. Its extended peripheral set (PCI, PCIe, Ethernet, RapidIO) simplifies integration with industrial I/O modules, and the hardware security engine protects control-plane traffic. Verify the operating temperature grade against the NXP datasheet ordering table for harsh-environment deployments.
おすすめ
Telecom Base Station Controllers
The MPC8548PXAUJC557 is used in 3G/4G base station controllers and small-cell baseband units where the e500 core runs the real-time operating system and the integrated security engine secures backhaul traffic. Dual PCI Express ports connect to baseband and radio cards, while the DDR2 controller feeds high-bandwidth DSP arrays. The 783-FCPBGA package's high pin count allows direct connection to all peripherals without external bridges, saving board area. A solid thermal via array and top-side heatsink are required at full CPU load.
おすすめ
Network Attached Storage Controllers
For mid-range NAS controllers, the MPC8548PXAUJC557's e500 core runs file-system services while the integrated security engine accelerates encrypted-volume I/O (AES-XTS for self-encrypting drives). PCI Express links to SATA/SAS controller ASICs, and the Gigabit Ethernet MACs aggregate network throughput. The 32-bit data path is adequate for mid-volume NAS but limits peak bandwidth; high-end NAS designs migrate to the dual-core MPC8572E or QorIQ P2xxx/P4xxx families.
おすすめ
Line Cards for Multi-Service Switches
The MPC8548PXAUJC557 is widely deployed on line cards for carrier-grade multi-service switches, where it manages forwarding-plane programming, QoS policy, and per-port statistics. Its RapidIO and PCI Express ports connect to the switch fabric, while Gigabit Ethernet ports handle OAM and synchronization traffic. Hardware encryption offloads MACsec processing for transport security. Design must keep SERDES traces length-matched within the 783-FCPBGA breakout, and signal integrity simulations are mandatory before layout freeze.

設計ノート
The 783-FCPBGA (29x29 mm) package demands a high-layer-count PCB - typically 8 or more layers - with microvia or via-in-pad construction for the BGA breakout. DDR2 traces must be length-matched within the JEDEC DDR2 spec; SERDES lanes (PCI Express, RapidIO, SGMII) require controlled-impedance routing with 100 ohm differential pairs and tight length matching (typically < 5 mil tolerance). Reference the NXP AN-3661 layout application note and run signal-integrity simulations before layout freeze.
At 1.333 GHz core clock, the MPC8548PXAUJC557 dissipates approximately 8-12 W typical. The 783-FCPBGA package uses thermal-balls beneath the die; a thermal via array (typically 0.3 mm pitch) on the inner board layers connects to a copper spreader, and a top-side heatsink with thermal interface material is required for production designs. Estimate: with theta_JA around 12-15 C/W (heatsink-attached), a 10 W dissipation yields a 120-150 C junction rise above ambient - place the heatsink and verify with thermal imaging during prototype bring-up.
The MPC8548PXAUJC557 requires a multi-rail power supply: a core voltage (typically 1.0-1.1 V at high current), a DDR2 I/O voltage (1.8 V), a 3.3 V peripheral rail, and a 2.5 V SERDES analog rail. Each rail needs bulk decoupling (10-22 uF ceramic) placed within 1 cm of the supply balls, plus high-frequency decoupling (0.1 uF + 1 nF) at every supply cluster. Power-on reset sequencing per the NXP hardware specification is mandatory; failure to sequence correctly can latch the security engine in a state that requires a full power cycle.
