MPC885ZP66 Présentation
A microprocessor (MPU) is the central processing unit of an embedded system, executing instructions fetched from memory and coordinating system peripherals. The MPC885 sits inside the MPU -> embedded processor -> microcontroller/SoC -> semiconductor taxonomy, and is positioned as a low-power communications SoC with integrated MAC, UART, I2C, SPI, USB, and HDLC/ATM controllers that historically offloaded the CPU in routers, DSLAMs, and PBX systems.
Key specifications include a single 32-bit core running at 66 MHz, 4 KB instruction and data caches, integrated Ethernet MACs, a 32-bit PCI bridge, and a memory controller supporting SDRAM, DRAM, SRAM, Flash, and ROM. The 357-PBGA package supplies the high I/O count required for the parallel system bus, two 10/100 MII Ethernet interfaces, USB, and serial channels.
Architecturally the device combines the Power Architecture CPU with the CPM (Communications Processor Module), a RISC engine that handles DMA and serial protocols independently of the core, freeing CPU bandwidth for routing and protocol-stack work. Power is typically supplied at 3.3 V I/O with a 1.8 V core rail, and the part supports several low-power modes for energy-conscious designs.
Typical uses include industrial routers, ISDN/DSL gateways, two-port 10/100 Ethernet switches, embedded firewalls, PBX control cards, and legacy 32-bit serial-control subsystems. The wide peripheral integration makes it a fit for compact, BOM-conscious designs.
When designing in, plan bypass capacitors for both core and I/O rails within 25 mm of the balls, route the 32-bit system bus with impedance control, and allocate adequate thermal copper to keep the junction under the 95 C limit. Refer to the MPC885 Hardware Specifications for power-up sequencing.

Applications typiques
MPC885ZP66 convient pour 7 applications: Industrial Router and Gateway, ISDN / DSL Modem Termination, Two-Port 10/100 Ethernet Switch, Embedded Firewall and Security Appliance, PBX Control Card, Industrial Serial-Control Subsystem, Legacy Telecom Line Card.
Industrial Router and Gateway
The MPC885ZP66's dual 10/100 Ethernet MAC and integrated CPM offload engine suit small-to-mid-scale industrial routers and protocol-conversion gateways. At 66 MHz the Power Architecture core runs routing tables, NAT, and firewall state while the CPM independently handles HDLC/PPP WAN links, leaving CPU cycles free for management and queuing tasks. The single-chip integration of PCI, USB, UART, I2C, and SPI reduces BOM and PCB area versus discrete designs. Power dissipation of roughly 1.0-1.5 W typical at full activity, combined with the 0-95 C commercial temperature range, lets the part sit in sealed enclosures without active cooling. Per the NXP MPC885 Hardware Specifications document the part supports low-power modes that are useful in energy-aware edge gateways.
Recommandé
ISDN / DSL Modem Termination
ISDN and DSL termination cards traditionally pair a communications MPU with a PHY or transceiver, and the MPC885ZP66 was designed for exactly this role. The CPM's HDLC and ATM engines handle WAN framing at line rate while the 66 MHz core runs routing, encapsulation, and management protocols. The 32-bit external data bus and integrated SDRAM controller interface directly to burst-mode memory without glue logic, and the PCI bridge enables co-processor boards for higher-layer termination stacks. Compared with a discrete CPU + ASIC approach, the MPC885ZP66 typically reduces part count by 8-12 ICs and shrinks PCB area by roughly 30 percent. The 3.3 V I/O plus 1.8 V core supply simplifies power-tree design versus 5 V legacy designs.
Recommandé
Two-Port 10/100 Ethernet Switch
For small-form-factor Ethernet switches in industrial and SMB markets, the MPC885ZP66 provides the management plane plus two MACs in one package, leaving PHYs as the only external interface components. The 66 MHz core executes spanning tree, VLAN, and SNMP agents while the PCI bus connects to a switch fabric companion chip. USB and serial channels expose a management console for CLI access. Estimated: at 66 MHz with both Ethernet ports active, the core draws roughly 1.0-1.2 W and the CPM offload keeps frame latency below 100 microseconds end-to-end. The 357-PBGA ball grid is dense enough that a 4-layer 1.6 mm PCB with 0.2 mm microvias is sufficient for most designs, per NXP application notes.
Recommandé
Embedded Firewall and Security Appliance
Compact firewall appliances for branch offices rely on a single processor that can drive two Ethernet segments and run filtering at line rate. The MPC885ZP66's two 10/100 MACs map directly to WAN and LAN ports, the CPM handles packet header parsing while the core executes stateful filtering, NAT, and VPN acceleration paths. The PCI bridge allows optional hardware-crypto daughter cards for AES or IPsec offload. Power draw of approximately 1-1.5 W at typical traffic loads keeps fan-less enclosures viable, important for desktop security appliances. The 0-95 C commercial operating range covers most office environments, and the long-life-cycle nature of the MPC8xx family suits security appliances that remain in service for 7-10 years.
Recommandé
PBX Control Card
The MPC885ZP66 was a common control-plane processor for enterprise and SMB PBX cards, integrating the host CPU and multi-channel serial offload in one device. The CPM's HDLC controllers handle T1/E1 framing and Q.SIG or ISDN PRI signaling, while the 66 MHz core runs call control, billing, and VoIP signalling stacks. The PCI bus connects to DSP daughter cards for voice processing, and the integrated USB and serial channels expose operator consoles. Per NXP application references, the architecture scales from small 8-channel systems up to 120+ channels when paired with external TDM switches. Compared with discrete MPU + serial-controller designs, the integrated CPM typically saves 4-6 support ICs.
Recommandé
Industrial Serial-Control Subsystem
Factory automation and SCADA subsystems often need a 32-bit controller with multiple serial channels plus USB and PCI host support for sensor aggregators. The MPC885ZP66's CPM provides up to four SCC channels plus several SCC-equivalent serial controllers, exposing RS-232/485, HDLC, and transparent serial modes simultaneously. The 66 MHz Power Architecture core runs real-time control loops or protocol stacks such as Modbus or Profibus. The 357-PBGA package withstands industrial shock and vibration better than leaded parts due to its low profile and coplanar ball grid, and the 0-95 C commercial temperature range suits most indoor factory environments. Estimated: junction temperature rise at full load is approximately 15-20 C above ambient with a moderate copper pour.
Recommandé
Legacy Telecom Line Card
Compact line cards for legacy TDM and ATM systems continue to use the MPC885ZP66 because its integrated CPM, dual Ethernet, and PCI bridge replace what previously required three or four chips. At 66 MHz the core handles per-channel control and signalling while the CPM services ATM AAL or HDLC framing at full line rate. The 32-bit external bus connects directly to TDM framers and SDH/SONET mappers without glue logic, reducing BOM and improving timing margin. Industrial temperature variants exist for outdoor cabinets, while the standard 0-95 C version serves central-office rack environments. The part's longevity and second-source availability through NXP's legacy product programme make it attractive for telecom refresh versus riskier redesigns.

Principaux différenciateurs
- On-chip dual 10/100 Ethernet MAC plus dedicated CPM offload (vs MPC880ZP66)
- Full peripheral set retains USB, PCI, dual Ethernet (vs MPC875ZP66)
- Original legacy non-RoHS speed grade retained for legacy builds (vs MPC885CVR66)
Notes de conception
Estimated: at 66 MHz with both Ethernet MACs active and the CPM running a typical WAN protocol stack, the MPC885ZP66 dissipates roughly 1.0-1.5 W. The 357-PBGA package has a thermal resistance of approximately 18-22 C/W with a moderate copper pour, so junction temperature rise above ambient is on the order of 20-30 C. Place 0.1 microfarad ceramic bypass capacitors within 25 mm of each VDD ball, and route the 1.8 V core and 3.3 V I/O rails on separate planes to minimise switching-noise coupling. Power sequencing requires 3.3 V I/O to come up before or with 1.8 V core; refer to the NXP Hardware Specifications document for the exact order.
The 357-ball PBGA at 25 mm square demands at least a 4-layer PCB with 0.2 mm microvia escape for the inner rows. Route the 32-bit external data bus with controlled impedance and length-match within 50 mils across all bits to avoid setup/hold violations on synchronous DRAM accesses. Provide at least 100 mm squared of unbroken ground copper directly under the package to control thermal rise and EMC. Decoupling clusters of 10 microfarad bulk + 0.1 microfarad + 1 nanofarad capacitors belong within 10 mm of the ball grid to suppress core-voltage transients.
Do not confuse the legacy MPC885ZP66 (non-RoHS, Z suffix) with the MPC885CVR66 (RoHS-compliant, C prefix on suffix); parts share the same 357-PBGA footprint but differ in lead finish. The bus-mode reset configuration is latched on PORESET release from the external reset controller; missing the configuration cycle traps the CPU in a reset state. The CPM's per-channel interrupt enables must be cleared before changing serial protocols to avoid spurious interrupts during reconfiguration. Finally, verify the silicon revision (visible in JTAG IDCODE) matches the version of the Hardware Specifications you are reading, as register definitions between revisions have shifted in earlier mask sets.
Informations de conformité
The 'Z' suffix in MPC885ZP66 indicates a leaded (non-RoHS) ball finish per historical NXP/Freescale part numbering. For RoHS-compliant builds use the MPC885CVR66 or MPC885CZP66 variants. AEC-Q100 is not applicable to a communications MPU; industrial temperature grades are not stock-listed for this speed grade.
