NXP Semiconductors MPC875VR133

Overview

MPC875VR133 from Freescale Semiconductor is a PowerQUICC™ integrated communications processor combining a 133 MHz MPC8xx core, dual Fast Ethernet controllers (10/100 Mbps), USB 2.0 host/function interface, security engine (AES/DES/SHA), and CPM-based serial peripherals - deployed in telecom edge routers, industrial gateways, and secure network appliances requiring deterministic real-time packet processing.

For engineers reviewing the MPC875VR133 datasheet, MPC875VR133 pinout, MPC875VR133 application, or MPC875VR133 equivalent, this page delivers verified core frequency, cache configuration, Ethernet PHY interface support (MII/RMII), security acceleration capabilities, and thermal/power specifications directly traceable to Freescale's MPC875EC Rev. 4 hardware specification.

Technical Context

The MPC875VR133 implements a 32-bit Power Architecture™ core with separate 8-Kbyte instruction and data caches (two-way set-associative), 32-entry MMU TLBs supporting 4/16/512 KB and 8 MB page sizes, and on-chip bus arbitration for dynamic memory access across eight banks. Its CPM executes serial protocols independently via 8-Kbyte dual-port RAM and SDMA channels.

It integrates a dedicated security engine with AESU (128/192/256-bit keys, ECB/CBC/CTR), DEU (DES/3DES), and MDEU (SHA-1/SHA-256, MD5, HMAC), all accessible through a crypto-channel with 256-byte buffers and DMA-controlled multi-command descriptors - enabling wire-speed IPsec/SSL offload without CPU intervention.

Key Specifications

Pinout & Package

The MPC875VR133 is housed in a 256-pin PBGA package (17 mm × 17 mm, 1.0 mm ball pitch) with thermal pad exposed on underside for board-level heat conduction.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar communications processor applications.

Compared with MPC875VR133, the MPC875VR100 trades 33 MHz of core speed for reduced thermal load and broader bus-mode flexibility, while the MPC885CZQ133 extends functionality with PCI and larger cache at the cost of mechanical and layout incompatibility - making MPC875VR133 optimal for legacy-compatible, thermally constrained, dual-Ethernet embedded systems.

Availability

MPC875VR133 is available at Aetrix Electronics and suitable for secure networking appliances, industrial Ethernet gateways, telecom edge concentrators, and USB-based field diagnostic tools requiring stable component supply across extended lifecycle programs.

Supply support for MPC875VR133 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) was a leading designer of embedded processors and analog/mixed-signal ICs for automotive, industrial, and networking markets.

The MPC875VR133 belongs to the PowerQUICC™ family - engineered specifically for integrated communications processing in space-constrained, power-sensitive network infrastructure where real-time packet handling and hardware crypto acceleration are mandatory.

FAQ

What is the maximum operating junction temperature for MPC875VR133?

The MPC875VR133 has a maximum 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 4-layer PCB with ground/power planes and adherence to the RθJB = 20 °C/W specification per Freescale's MPC875EC Rev. 4 documentation.

Does MPC875VR133 support 5-V tolerant I/O pins, and which ones?

Yes, MPC875VR133 supports 5-V tolerant inputs on specific pins including PA[0:15], PB[14:31], PC[4:15], PD[3:15], PE[14:31], TDI, TDO, TCK, TRST, TMS, MII1_TXEN, and MII_MDIO. Per Freescale's DC specifications, these pins tolerate up to VDDH + 2.5 V (≤5.5 V total), but must never exceed that limit during power-up, power-down, or normal operation.

Can MPC875VR133 operate in both USB host and function modes simultaneously?

No, MPC875VR133 cannot operate as USB host and function simultaneously. Its USB module supports three distinct operational modes - function endpoint, host controller, or loopback diagnostic - selected at runtime via software configuration of the USB control registers. Concurrent dual-role operation is not implemented in the silicon per the MPC875EC Rev. 4 specification.

What memory types does the MPC875VR133 memory controller support without external glue logic?

The MPC875VR133 memory controller provides glueless interfacing to DRAM, SIMMs, SRAM, EPROMs, Flash EPROMs, and other memory devices across eight programmable banks. It supports dynamic bus sizing (8/16/32-bit), variable block sizes (32 KB–256 MB), and boot chip-select options for 8-, 16-, or 32-bit memory initialization - all confirmed in Section 3 of the MPC875EC Rev. 4 hardware spec.

Is the security engine in MPC875VR133 capable of accelerating TLS 1.2 handshake operations?

Yes, the MPC875VR133 security engine accelerates core cryptographic primitives required for TLS 1.2: AES-128/192/256 (CBC/CTR), SHA-256, and RSA key exchange (via software-managed DEU/MDEU coordination). While full TLS stack execution occurs in software, the hardware accelerators reduce handshake latency by offloading symmetric cipher and hash computations - as documented in Freescale Application Note AN2523.
