Product details
Overview
MPC885CVR66 from Freescale Semiconductor is a Power Architecture™-based integrated communications processor combining a 66 MHz MPC8xx core, dual 10/100 Fast Ethernet controllers (FEC), USB 2.0 full-/low-speed host/function interface, serial ATM/UTOPIA support, and a hardware security engine with DES/3DES, AES-128/192/256, and SHA-1/256 acceleration - deployed in carrier-grade DSLAMs, enterprise edge routers, and secure VPN gateways.
For engineers reviewing the MPC885CVR66 datasheet, MPC885CVR66 pinout, MPC885CVR66 application, or MPC885CVR66 equivalent, key selection criteria include its 357-pin PBGA package, 1.8 V core / 3.3 V I/O operation, IEEE 1149.1 JTAG debug support, dual FEC with MII/RMII, and ROM-resident AAL2/VBR functionality for ATM traffic shaping.
Technical Context
The MPC885CVR66 integrates three major subsystems on a single die: an MPC8xx 32-bit RISC core with 8 KB instruction and 8 KB data caches, a system integration unit (SIU) handling clock synthesis, reset control, PIT, watchdog, and bus arbitration, and a communications processor module (CPM) with 8 KB dual-port RAM, four baud rate generators, and RISC-based serial channel control.
Its security engine implements dedicated crypto-channel logic with DEU, AESU, and MDEU units supporting concurrent IPsec/SSL/TLS offload; the CPM supports up to three SCCs (including UTOPIA L2-compliant master/slave operation) and two SMCs, while the SIU provides glueless DRAM/SRAM/Flash interfacing across eight programmable memory banks with up to 30 wait states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | MPC8xx 32-bit Power Architecture core at 66 MHz - enables deterministic real-time packet processing with branch prediction and lockable cache blocks. |
| Memory Interface | 32-bit data bus, 32 address lines, 8-bank DRAM controller - supports glueless connection to DDR SDRAM, SRAM, and Flash without external logic. |
| Ethernet | Dual 10/100 Mbps FEC with MII/RMII - allows simultaneous WAN/LAN port bridging or redundant link failover in routing applications. |
| USB | USB 2.0 full-/low-speed host/function endpoint - enables embedded diagnostics via loop-back mode and peripheral attachment without external PHY. |
| Security Engine | Hardware-accelerated DES/3DES, AES-128/192/256, SHA-1/256 - offloads IPsec ESP/AH and TLS record encryption, reducing CPU load by >80% vs. software-only implementation. |
| ATM/UTOPIA | Serial ATM + UTOPIA L2-compliant interface with FIFO buffering - supports direct cell-level switching and multi-PHY statistical counters for DSL aggregation. |
| Power Supply | 1.8 V core (VDDL), 3.3 V I/O (VDDH), 1.8 V PLL (VDDSYN) - requires strict sequencing: VDDL must not exceed VDDH during power-up/down to prevent ESD diode conduction. |
Pinout & Package
The MPC885CVR66 is housed in a 357-ball PBGA package (19 × 19 mm, 1.27 mm pitch) with thermal pad exposed on underside for board-level heat dissipation. Ball mapping follows JEDEC MO-205AC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDL (Balls A1–A4, B1–B4) | Core power supply | Must be decoupled with ≥4×0.1 µF capacitors near package corners; voltage must stay within 1.7–1.9 V and never exceed VDDH. |
| VDDH (Balls C1–C4, D1–D4) | I/O power supply | Supplies all digital I/O including MII, USB, and PCI-like buses; pins PA[0:15], PB[14:31], etc., are 5 V tolerant but limited to VDDH + 2.5 V max. |
| EXTAL/EXTCLK (Balls T18/T19) | External clock input | Accepts crystal (EXTAL) or buffered clock (EXTCLK); VIHC = 0.7×VDDH min ensures reliable PLL lock at 66 MHz core frequency. |
| TMS/TCK/TDO/TDI (Balls R16–R19) | JTAG test access port | IEEE 1149.1-compliant boundary scan interface used for production testing, in-circuit debugging, and flash programming. |
| MII1_TXEN/MII1_TXD[0:3]/MII1_RXD[0:3] (Balls K1–K12) | FEC1 Media Independent Interface | Direct connection to PHY without level shifters; supports 10/100 Mbps half/full-duplex operation with auto-negotiation signaling. |
| USB_DP/USB_DM (Balls H1/H2) | USB differential pair | Full-speed (12 Mbps) or low-speed (1.5 Mbps) signaling; internal transceivers eliminate need for external USB PHY in function/host modes. |
Key Features
| Feature | Design Value |
|---|---|
| ROM-resident AAL2/VBR | Enables voice-over-ATM transport without microcode loading - reduces boot time and eliminates external RAM dependency for VoIP gateway applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC885CZQ66 | Same core, identical feature set, but in 357-pin PBGA with exposed thermal pad - differs only in moisture sensitivity level (MSL 3 vs. MSL 4 for MPC885CVR66). | Identical functional replacement; used in higher-reliability industrial deployments where enhanced thermal performance is required. | Select MPC885CZQ66 when board-level thermal resistance must be minimized below 17 °C/W (RθJB) or extended temperature operation (–40°C to +100°C) is mandatory. |
| MPC875VR66 | Lacks security engine, UTOPIA interface, and second FEC; retains single FEC, USB, and SCC/SMC count reduced to 2/1 - lower gate count and power (280 mW typical). | Suitable for non-secure, non-ATM applications like basic Ethernet bridges or USB host controllers where crypto offload is unnecessary. | Choose MPC875VR66 only if security acceleration and ATM support are excluded from system requirements - avoids over-specification and reduces licensing costs. |
Compared with MPC885CVR66, MPC885CZQ66 offers identical functionality with improved thermal dissipation for high-density layouts, while MPC875VR66 sacrifices ATM, crypto, and dual-FEC capability to achieve lower cost and power - making it viable only in simplified networking roles where those features are unused.

FAQ
What is the maximum operating junction temperature for the MPC885CVR66?
The MPC885CVR66 has a maximum guaranteed junction temperature (TJ) of 95°C under standard operating conditions and 100°C in extended temperature grade configurations. This rating assumes proper thermal design using a four-layer PCB with power/ground planes and adherence to the specified RθJB = 17°C/W thermal resistance. Exceeding TJ(max) risks permanent degradation of the embedded MMU and cache coherency logic within the MPC885CVR66.
Does the MPC885CVR66 support pin-compatible migration from the MPC866?
No, the MPC885CVR66 is not pin-compatible with the MPC866. While both belong to Freescale's PowerQUICC family and share architectural similarities, the MPC885CVR66 uses a 357-ball PBGA package with different ball pitch, signal grouping, and power/ground distribution compared to the MPC866's 272-ball PBGA. Migration requires PCB redesign and firmware adaptation due to differences in CPM register layout and security engine initialization sequences specific to the MPC885CVR66.
Can the MPC885CVR66 operate in 1:1 bus mode at 66 MHz core frequency?
Yes, the MPC885CVR66 supports 1:1 bus mode at 66 MHz core frequency, allowing synchronous operation of the CPU and external bus interface. In this configuration, the external bus operates at 66 MHz with up to 30 programmable wait states per memory bank, enabling reliable interfacing with slower SRAM or Flash devices. The 1:1 mode is explicitly validated in the MPC885EC Rev. 7 specification and delivers optimal timing margin for glueless memory connections in cost-sensitive designs using the MPC885CVR66.
What USB modes does the MPC885CVR66 support, and are external PHY components required?
The MPC885CVR66 supports USB function endpoint, USB host controller, and diagnostic loop-back modes - all implemented with fully integrated transceivers. No external PHY is required for full-speed (12 Mbps) or low-speed (1.5 Mbps) operation, as the USB_DP/USB_DM pins drive compliant differential signaling directly. The MPC885CVR66's USB controller handles CRC16/CRC5, NRZI encoding/decoding, and automatic retransmission, making it self-contained for embedded host-peripheral applications such as firmware update dongles or diagnostic tools.
How does the security engine in the MPC885CVR66 accelerate IPsec processing?
The MPC885CVR66 security engine accelerates IPsec through dedicated hardware units: the DEU executes DES/3DES in ECB/CBC modes, the AESU handles AES-128/192/256 in CBC/counter modes, and the MDEU computes SHA-1/256 and MD5 hashes. These units operate via a crypto-channel that accepts multi-command descriptor chains, enabling pipelined processing of inbound/outbound IPsec packets without CPU intervention. Benchmarks show the MPC885CVR66 achieves 45 Mbps encrypted throughput - a 3.2× improvement over software-only execution on the same 66 MHz core.
