MPC885CVR66-FR Visão geral
Background: A PowerQUICC (PowerPC QUICC) MPU is an embedded microprocessor that combines a Power Architecture CPU core with on-chip peripherals originally designed for networking, telecom, and industrial control. The MPC8xx family pioneered the integration of a communications processor module (CPM) with a general-purpose core, enabling a single chip to handle both protocol processing and control-plane tasks. The MPC885 sits within the broader taxonomy: microprocessor -> embedded MPU -> PowerQUICC family -> communications processor -> Power Architecture device -> semiconductor.
Key differentiating features of the MPC885CVR66-FR include the integrated CPM supporting multiple serial channels (FCCs, SCCs, SMC, SPI, I2C), a 32-bit RISC communications engine, dual 10/100 Ethernet MAC support via the FCCs, a 32-channel DMA controller, and memory control for SDRAM, SRAM, EPROM, and flash. The integrated peripherals eliminate external protocol bridges and reduce BOM cost in router, switch, and access-multiplexer designs.
From an architectural perspective, the MPC885CVR66-FR uses a 0.18 micrometer process and separates the 3.3 V I/O supply from the 1.9 V core supply, allowing low core power dissipation while maintaining 5 V-tolerant I/O on selected interfaces. The CPM offloads serial DMA, HDLC/PPP framing, and ATM SAR work from the core, freeing CPU cycles for routing and management-plane software.
Typical applications include WAN access routers, ISDN terminal adapters, xDSL modems and CPE, industrial serial-to-Ethernet gateways, and legacy telecom control boards. The combination of 87 MIPS core performance and integrated communications controllers makes it suitable for low-to-mid throughput edge devices where a single-chip solution lowers cost and board area.
When designing with this part, ensure the 1.9 V core regulator is sequenced correctly relative to the 3.3 V I/O rail, observe the 357-ball PBGA ballout for power/ground ball distribution to maintain signal integrity, and verify that the CPM firmware matches the silicon revision. Refer to the manufacturer hardware specifications for the exact thermal design current per supply domain.

Aplicações típicas
MPC885CVR66-FR é adequado para 6 aplicaçãos: WAN Access Router, ISDN Terminal Adapter / xDSL CPE, Industrial Serial-to-Ethernet Gateway, Legacy Telecom Control Board, Embedded Linux Router / Firewall Appliance, Point-of-Sale Terminal Controller.
WAN Access Router
The MPC885CVR66-FR's integrated dual 10/100 Ethernet MACs via the FCCs and its 87 MIPS Power Architecture core make it a fit for low-to-mid throughput WAN access routers. The CPM offloads PPP, HDLC, and Ethernet framing from the core, freeing cycles for routing-table lookups and management protocols. In a typical design the MPC885 sits between an external PHY on the LAN side and an xDSL or ISDN transceiver on the WAN side, while the 32-bit memory bus drives 32 to 64 MB of SDRAM and 4 to 16 MB of flash. The 66 MHz clock is sufficient for T1/E1-rate and basic ADSL2+ forwarding, though VDSL2 line rates require the faster MPC866/MPC8272 family.
Recomendado
ISDN Terminal Adapter / xDSL CPE
The MPC885CVR66-FR is a long-standing platform for ISDN terminal adapters and xDSL CPE where the integrated CPM handles HDLC, V.110, and PPP framing without an external bridge. Its 3.3 V I/O and 1.9 V core supplies simplify the bill of materials when paired with an integrated line driver. The 87 MIPS core comfortably runs PPPoE, IP routing, and a small web management stack at ADSL2+ rates. The 357-PBGA offers the ground-ball density needed for the multiple serial interfaces typical in this application class, and the industrial temperature grade suits outdoor DSLAM-side deployments.
Recomendado
Industrial Serial-to-Ethernet Gateway
Industrial serial-to-Ethernet gateways leverage the MPC885CVR66-FR's rich serial channel set (FCCs, SCCs, SMC, SPI, I2C) to bridge RS-232, RS-485, and Modbus devices onto a 10/100 Ethernet network. The -40 C to +100 C operating range supports factory-floor enclosures, and the 357-PBGA's thermal mass handles continuous CPM activity. Designers typically pair the MPC885 with a supervisory reset IC and 32 MB of SDRAM, then load embedded Linux or a small RTOS with a TCP-to-serial daemon. The integrated DMA controller moves serial data with minimal CPU overhead, which keeps the latency budget tight for Modbus polling.
Recomendado
Legacy Telecom Control Board
Telecom control boards for switching systems, cross-connects, and access multiplexers use the MPC885CVR66-FR as a low-cost control-plane processor. The CPM's TDM support and HDLC controllers connect directly to framer devices, while the core runs the management software. The dual 3.3 V / 1.9 V supply scheme matches legacy telecom power rails, simplifying integration into existing -48 VDC systems. Compared with newer PowerQUICC III devices, the MPC885 draws less power and costs less, which matters for densely populated control shelves. The 357-PBGA footprint remains footprint-compatible with the broader MPC8xx family for board reuse.
Recomendado
Embedded Linux Router / Firewall Appliance
The MPC885CVR66-FR runs embedded Linux distributions with available BSPs and is therefore a viable platform for small-office router/firewall appliances. The 87 MIPS core is adequate for stateful packet filtering and NAT at sub-100 Mbps throughput; designs that need gigabit throughput must move to MPC8272 or Layerscape devices. The 357-PBGA package and the 32-bit SDRAM controller support the standard Linux memory map and flash file systems (JFFS2, UBI), while the dual Ethernet MACs allow WAN/LAN segmentation. The integrated DMA and CPM reduce driver complexity in the Linux kernel tree.
Recomendado
Point-of-Sale Terminal Controller
POS terminals with mixed serial peripherals (cash drawer, receipt printer, magnetic-stripe reader, keypad) benefit from the MPC885CVR66-FR's multiple SCC/SMC channels and integrated Ethernet. The -40 C to +100 C range covers retail back-room and kiosk environments, and the 357-PBGA provides enough ground balls for clean EMC on the Ethernet PHY side. A typical design pairs the MPC885 with 32 MB SDRAM, 8 MB NOR flash, a small TFT controller, and a 10/100 Ethernet PHY for backend reporting. The CPM's DMA keeps printer and reader latency predictable under load.

Notas de projeto
The MPC885CVR66-FR requires two supplies: 3.3 V for I/O and 1.9 V for the core. Sequence the 1.9 V rail before or simultaneously with the 3.3 V rail; never allow the 3.3 V rail to come up while the 1.9 V core rail is off. A small buck regulator such as the TPS76701 with power-good output tied to a voltage supervisor prevents latch-up and brown-out issues. Decouple each supply domain with 100 nF X7R caps placed within 5 mm of every power/ground ball pair, plus a 10 uF bulk cap per rail.
Estimated: at 66 MHz full activity on the CPM and core, typical core current is on the order of 150 mA at 1.9 V plus CPM I/O current at 3.3 V. Total dissipation is roughly 0.5 to 0.8 W in worst-case CPM-heavy workloads. The 357-PBGA exposes a thermal pad array; stitch thermal vias to inner ground planes on the PCB to keep junction temperature below the +100 C limit in sealed enclosures. Use a 4-layer board with a 1 oz copper inner plane as a baseline.
Do not substitute the MPC880 family in place of the MPC885 if your firmware relies on the dual 10/100 Ethernet MACs - the MPC880 omits these MACs and uses different CPM masks. Also verify silicon revision against your BSP/RTOS image; some revisions disable specific FCC or SCC channels. When laying out the 357-PBGA, keep at least 8 ground balls in a checker pattern under the die to control ground bounce on the parallel memory bus, and use matched-length traces for the SDRAM clock, clock-enable, and data strobes.
