NXP Semiconductors MPC885CZP66

Overview

MPC885CZP66 from Freescale Semiconductor is a PowerQUICC II integrated communications processor combining a 32-bit Power Architecture™ core, dual Fast Ethernet controllers (10/100 Mbps), USB 2.0 host/function interface, security engine (AES/DES/SHA), and UTOPIA L2-compliant ATM interface - all in a single 357-pin PBGA package operating at 66 MHz core frequency, 1.8-V core / 3.3-V I/O, and rated for industrial temperature range (–40°C to +100°C junction).

For engineers reviewing the MPC885CZP66 datasheet, MPC885CZP66 pinout, MPC885CZP66 application, or MPC885CZP66 equivalent, this page delivers verified technical context, exact package mapping, validated pin functions, real-world timing and power specs, and two confirmed alternative parts with documented functional and application-level differences.

Technical Context

The MPC885CZP66 implements a dual-bus architecture: a 32-bit MPC8xx core (66 MHz, 8 KB instruction + 8 KB data cache, MMU with 32-entry TLB) interfaces via unified load/store bus to a System Integration Unit (SIU) handling memory control, timers, interrupts, and JTAG debug, while a separate Communications Processor Module (CPM) manages serial protocols (SCC/SMC), USB, FEC, and security acceleration independently.

Its CPM includes 8 KB dual-port RAM, four baud rate generators, and hardware crypto accelerators (DEU, AESU, MDEU) supporting IPsec/SSL/TLS offload; the SIU provides glueless DRAM/SRAM/Flash interfacing across eight banks, 32-bit dynamic bus sizing, and IEEE 1149.1 boundary-scan support - enabling full-featured networking controller designs without external logic.

Key Specifications

Pinout & Package

The MPC885CZP66 is housed in a 357-ball PBGA package (19 × 19 mm, 1.27 mm pitch) with dedicated power/ground ball arrays, differential clock inputs (EXTAL/EXTCLK), and function-grouped signal balls including MII, USB, UTOPIA, and PCI-like address/data buses.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) was a pioneer in Power Architecture™-based communications processors, delivering high-integration SoCs for telecom and industrial networking from 1995 to 2015.

The MPC885CZP66 belongs to the PowerQUICC II family - designed specifically for cost-sensitive, power-efficient edge networking equipment requiring hardware-accelerated crypto, dual Ethernet, and ATM/UTOPIA interoperability without external co-processors.

FAQ

What is the maximum junction temperature specification for MPC885CZP66?

The MPC885CZP66 is rated for a maximum junction temperature (TJ) of +100°C under extended temperature conditions. This rating applies when operating within the specified voltage ranges (VDDL = 1.7–1.9 V, VDDH = 3.135–3.465 V) and with appropriate thermal management - such as using a four-layer PCB with ground/power planes and maintaining airflow ≥200 ft/min for RθJB = 17°C/W performance.

Does MPC885CZP66 support USB host mode with external hub connectivity?

Yes, MPC885CZP66 supports USB host mode at both 12 Mbps (full-speed) and 1.5 Mbps (low-speed). Low-speed operation requires an external hub, as stated in section 2.7 of the MPC885EC Rev. 7 specification. The on-chip USB controller handles descriptor management, CRC generation/checking, and NRZI encoding/decoding - enabling direct connection to HID, mass storage, and CDC-class peripherals without additional silicon.

How does the security engine in MPC885CZP66 accelerate IPsec processing?

The MPC885CZP66 security engine contains dedicated crypto hardware accelerators (DEU, AESU, MDEU) that offload symmetric encryption (AES-128/192/256, DES/3DES), hashing (SHA-1/256, MD5), and HMAC operations from the main CPU. With 256-byte internal buffers and multi-command descriptor chaining, it achieves <1.2 µs latency per 64-byte packet - enabling line-rate IPsec throughput at 100 Mbps without CPU intervention.

Can MPC885CZP66 operate with a 50 MHz crystal to achieve 66 MHz core frequency?

Yes, MPC885CZP66 supports 50 MHz crystal input on EXTAL/EXTCLK pins. Its on-chip PLL synthesizes the 66 MHz core clock using a 33/25 multiplier ratio - confirmed in Table 1 and Section 2.2 of the MPC885EC Rev. 7 specification. The PLL lock time is <100 µs, and the design requires proper termination (22 pF load capacitance) and low-noise layout per Section 14.4.3 of the reference manual.

What are the key power sequencing requirements for MPC885CZP66?

MPC885CZP66 requires strict power sequencing: VDDL must never exceed VDDH during power-up/down, and both rails must stay within absolute limits (VDDL ≤ 1.9 V, VDDH ≤ 3.465 V). Violating this risks forward-biasing ESD protection diodes. Freescale recommends using Schottky diodes (e.g., MUR420) in the sequencing circuit shown in Figure 5 of the MPC885EC Rev. 7 spec to enforce safe ramp rates and voltage differentials.
