NXP Semiconductors MPC885CVR133

Overview

MPC885CVR133 from Freescale Semiconductor is a Power Architecture™-based integrated communications processor combining a 133 MHz MPC8xx core, dual 10/100 Fast Ethernet controllers (FEC), USB 2.0 full-/low-speed host/function capability, UTOPIA L2-compliant ATM interface, and hardware security engine supporting DES/3DES, AES-128/192/256, SHA-1/256, and MD5. It targets broadband access gateways, DSLAMs, and secure edge routers requiring deterministic real-time packet processing.

For engineers reviewing the MPC885CVR133 datasheet, MPC885CVR133 pinout, MPC885CVR133 application, or MPC885CVR133 equivalent, key selection criteria include its 133 MHz core frequency with 2:1 bus ratio, 1.8 V core / 3.3 V I/O operation, 357-pin PBGA package, integrated security acceleration, and dual FEC + UTOPIA support for converged voice/data networking.

Technical Context

The MPC885CVR133 implements a three-module architecture: an MPC8xx RISC core with MMU, instruction/data caches (8 KB each), and branch prediction; a System Integration Unit (SIU) handling clock synthesis, reset control, JTAG, and watchdog; and a Communications Processor Module (CPM) with 8 KB dual-port RAM, four baud rate generators, and serial DMA channels supporting SCC/SMC protocols including HDLC, UART, IrDA, and ATM over SCC4.

Its security engine integrates dedicated crypto-channel, controller, and hardware accelerators (DEU, AESU, MDEU) enabling concurrent IPsec/SSL/TLS offload without CPU intervention. The device supports 2:1 bus mode only at 133 MHz core speed, with external bus operating up to 80 MHz, and features IEEE 1149.1 JTAG boundary-scan compliance for production testability.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature for the MPC885CVR133?

The MPC885CVR133 has a maximum junction temperature of 95 °C under standard operating conditions. This rating assumes proper PCB thermal design with four-layer board construction, thermal vias under the package, and adequate airflow. Exceeding this limit risks permanent degradation of the on-die cache coherency logic and security engine accelerators. Always validate thermal performance using the RθJB = 17 °C/W parameter with measured board temperature in final system configuration. The MPC885CVR133 must not operate above 95 °C junction temperature for reliable long-term function.

Does the MPC885CVR133 support USB host mode for external peripherals?

Yes, the MPC885CVR133 supports full USB 2.0 host controller functionality including control, bulk, interrupt, and isochronous transfers at both 12 Mbps (full-speed) and 1.5 Mbps (low-speed). It includes CRC16 generation/checking, NRZI encoding/decoding with bit stuffing, and flexible buffer management. Low-speed operation requires an external hub, and the host mode is validated for use with USB modems, flash drives, and diagnostic tools. The MPC885CVR133 USB subsystem is fully compliant with USB 2.0 specifications and operates independently of the main CPU core.

Can the MPC885CVR133 run in 1:1 bus mode at 133 MHz?

No, the MPC885CVR133 does not support 1:1 bus mode at 133 MHz core frequency. According to the official hardware specification (Rev. 7), the 133 MHz core speed mandates 2:1 bus ratio only, meaning the external bus must run at 66.5 MHz. Attempting 1:1 operation at 133 MHz violates timing constraints for address/data setup/hold and will result in memory controller instability and CPM descriptor corruption. The MPC885CVR133 supports 1:1 mode only at 66 MHz or 80 MHz core frequencies. This limitation is hardwired in the SIU clock synthesizer logic.

How does the security engine in the MPC885CVR133 accelerate IPsec processing?

The MPC885CVR133 security engine accelerates IPsec by offloading symmetric encryption (DES/3DES, AES-128/192/256), hash computation (SHA-1/256, MD5), and HMAC generation to dedicated hardware units (DEU, AESU, MDEU). These accelerators operate concurrently with the CPU core, process data in 256-byte blocks with flow control, and support multi-command descriptor chains. This reduces CPU cycles required for ESP/AH processing by >80%, enabling line-rate 100 Mbps IPsec throughput. The MPC885CVR133 security engine is specifically architected for RFC-compliant IPsec tunnel mode with no software intervention needed for crypto operations.

Is the MPC885CVR133 pin-compatible with the MPC880 series?

No, the MPC885CVR133 is not pin-compatible with MPC880-series devices despite sharing the same 357-ball PBGA package footprint. Key differences include the presence of the security engine block, additional FEC signals, UTOPIA-specific pins on SCC4, and distinct USB PHY interface routing. Pin assignments for VDDH, VDDL, and peripheral signals differ between MPC885 and MPC880 variants, and the MPC885CVR133 requires different power sequencing and decoupling. Migration from MPC880 to MPC885CVR133 necessitates PCB redesign and firmware adaptation due to these architectural and pinout-level incompatibilities.
