Product details
Overview
KMPC885VR133 from Freescale Semiconductor is a PowerQUICC II family integrated communications processor combining a 32-bit MPC8xx core, dual Fast Ethernet controllers (FEC), USB 2.0 host/function interface, security engine with AES/DES/SHA accelerators, and UTOPIA L2-compliant ATM interface - operating at 133 MHz core frequency, 1.8-V core / 3.3-V I/O, in a 357-pin PBGA package for telecom edge routing and secure gateway applications.
For engineers reviewing the KMPC885VR133 datasheet, KMPC885VR133 pinout, KMPC885VR133 application, or KMPC885VR133 equivalent, key selection criteria include its 133-MHz Power Architecture™ core with MMU and dual 8-KB caches, integrated crypto acceleration for IPsec/SSL offload, dual MII/RMII Ethernet MACs, and 5-V-tolerant I/O supporting legacy PHY interfacing without level shifters.
Technical Context
The KMPC885VR133 implements a unified 32-bit RISC core derived from Power Architecture™, executing branch-predicted instructions with conditional prefetch and two-way set-associative 8-KB instruction and data caches. Its memory management unit features 32-entry fully associative TLBs supporting 4/16/512 KB and 8 MB page sizes across 16 virtual address spaces.
It integrates a dedicated Communications Processor Module (CPM) with 8-KB dual-port RAM, four baud rate generators, three SCCs (including serial ATM and optional UTOPIA on SCC4), two SMCs, and time-slot assigner for T1/ISDN/PCM multiplexing - all synchronized via a shared internal bus with the SIU and security engine.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Frequency | 133 MHz - supports 2:1 CPU-to-bus ratio only; enables high-throughput packet processing with minimal external clock domain complexity. |
| Core Voltage | 1.7–1.9 V - requires tightly regulated low-noise supply; mandates strict sequencing relative to 3.3-V I/O to prevent ESD diode conduction. |
| I/O Voltage | 3.135–3.465 V - supports 5-V-tolerant pins (PA[0:15], PB[14:31], etc.) enabling direct connection to legacy 5-V PHYs without level shifters. |
| Cache | 8-KB instruction + 8-KB data - physically addressed, LRU-replaced, lockable per 128-bit block; eliminates software cache coherency management overhead. |
| Security Engine | AES-128/192/256, DES/3DES, SHA-1/256, MD5 - hardware-accelerated crypto-channel with 256-byte buffers; offloads IPsec/SSL/TLS processing from main CPU. |
| Ethernet Interfaces | Dual 10/100 Mbps FEC with MII/RMII - independent media access controllers supporting simultaneous full-duplex operation on separate PHYs. |
| USB Interface | USB 2.0 full-/low-speed host/function - supports control/bulk/interrupt/isochronous transfers; includes NRZI encoding, CRC16/5, and automatic retransmission. |
Pinout & Package
Package: 357-ball PBGA (19×19 mm, 1.27 mm pitch), RoHS-compliant, thermal pad exposed on underside for board-level heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDL | Core power supply | 1.8-V supply for CPU, caches, MMU, and CPM logic; must ramp after VDDH and not exceed it during power-up/down. |
| VDDH | I/O power supply | 3.3-V supply for all digital I/O including MII, USB, PCI-like buses; powers 5-V-tolerant pins with voltage clamping diodes. |
| EXTAL | Crystal oscillator input | Accepts 33.33 MHz crystal for PLL-based clock synthesis; requires external load capacitors and stable mechanical mounting. |
| MII1_TXEN | PHY transmit enable | Active-high signal controlling MII transmit data flow to first Ethernet PHY; 5-V tolerant, directly interfaces standard MII PHYs. |
| SCC4_DTX | UTOPIA data transmit | Serial ATM/UTOPIA L2 data output from SCC4; supports full-duplex master/slave operation with FIFO buffering for cell transmission timing. |
| SEC_CLK | Security engine clock | Derived from system clock; gates crypto accelerator operation and synchronizes DMA transfers to/from security engine buffers. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC885CZQ133 | Same die, identical electrical specs, but offered in lead-free 357-pin PBGA with different thermal pad design and JEDEC-standard marking. | Targeted at RoHS-2 compliant industrial deployments requiring documented Pb-free qualification and extended temperature range (–40°C to +100°C). | Select MPC885CZQ133 when lead-free compliance and extended temp operation are mandatory; KMPC885VR133 remains optimal for cost-sensitive telecom infrastructure with standard temp range. |
| MPC875VR133 | Lacks security engine and UTOPIA interface; retains dual FEC, USB, and same 133-MHz core but with reduced peripheral set and no crypto accelerators. | Suitable for non-encrypted Ethernet bridging or basic protocol conversion where crypto offload is unnecessary and ATM connectivity is absent. | Choose MPC875VR133 only if security and ATM functionality are excluded from system requirements; KMPC885VR133 provides full feature set for converged secure access nodes. |
Compared with MPC885CZQ133, KMPC885VR133 offers identical performance but differs in Pb-free compliance and thermal pad construction; versus MPC875VR133, KMPC885VR133 adds critical security acceleration and UTOPIA L2 support required for carrier-grade DSLAM and IPsec gateway designs.

FAQ
What is the maximum operating junction temperature for KMPC885VR133?
The KMPC885VR133 has a maximum guaranteed junction temperature (TJ) of 95°C under standard operating conditions and 100°C in extended temperature grade configurations. Thermal design must ensure TJ remains within these limits using the specified RθJB = 17°C/W and RθJC = 10°C/W values, with board-level copper planes and airflow management critical for sustained 133-MHz operation.
Does KMPC885VR133 support pin-compatible migration from MPC866 or MPC875?
No, KMPC885VR133 is not pin-compatible with MPC866 or MPC875 due to differences in ball count (357 vs. 272/256), power pin distribution, and I/O assignment. Migration requires PCB redesign; however, software compatibility exists at the Power Architecture™ ISA and CPM register level for firmware reuse across the PowerQUICC family.
Can KMPC885VR133 operate in 1:1 bus mode at 133 MHz?
No, KMPC885VR133 supports 133-MHz core operation only in 2:1 bus mode (core clock double the external bus clock). The 1:1 mode is limited to 66 MHz or 80 MHz core frequencies; attempting 133 MHz in 1:1 mode violates AC timing specifications and may cause data corruption on the external memory or peripheral bus.
What USB modes does KMPC885VR133 support and how are they configured?
KMPC885VR133 supports USB 2.0 full-speed (12 Mbps) and low-speed (1.5 Mbps) operation in both function endpoint and host controller roles, configurable via software-controlled mode bits in the USB control register. Function mode provides four endpoints (control/bulk/interrupt/isochronous); host mode supports control/bulk/interrupt/isochronous transfers with automatic preamble generation and loop-back diagnostics at 12 Mbps.
Is external memory required for KMPC885VR133 boot and runtime operation?
Yes, KMPC885VR133 requires external memory for boot and runtime: it lacks on-chip flash or ROM for program storage. Boot code must reside in external NOR flash or EPROM connected to the memory controller's boot chip-select; DRAM is required for OS execution, packet buffers, and CPM dual-port RAM shadowing. Internal 8-KB instruction and data caches reduce external memory bandwidth demand but do not eliminate the need for external memory.
