NXP Semiconductors MPC866TCZP100A

Overview

MPC866TCZP100A from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ II communications processor integrating a 32-bit PowerPC core, CPM-based serial peripherals, and Fast Ethernet controller. It operates at up to 100 MHz CPU frequency with 4-Kbyte instruction and 4-Kbyte data caches, 1.8-V core / 3.3-V I/O supply, and supports ATM-enhanced SAR functionality in telecom edge devices.

For engineers reviewing the MPC866TCZP100A datasheet, MPC866TCZP100A pinout, MPC866TCZP100A application, or MPC866TCZP100A equivalent, key selection criteria include its 357-pin PBGA package, IEEE 802.3-compliant FEC, UTOPIA Level 2 interface, dual 16-bit timers, and support for MII/UTOPIA simultaneous operation in DSL access concentrators and ATM edge routers.

Technical Context

The MPC866TCZP100A implements a single-issue PowerPC core with MMU, 32-entry ITLB/DTLB, and physically addressed caches. Its CPM subsystem executes communication-specific RISC instructions and manages up to 16 SDMA channels across four SCCs and two SMCs.

It integrates a Fast Ethernet Controller supporting full-duplex 10/100Base-T via MII and half-duplex UTOPIA Level 2 simultaneously, plus enhanced SAR features including OAM performance monitoring, multi-PHY UTOPIA support, and AAL2/VBR ROM-resident firmware - all without external microcode.

FAQ

What is the maximum operating frequency of the MPC866TCZP100A?

The MPC866TCZP100A is rated for a maximum CPU frequency of 100 MHz. At this speed, it supports a 50-MHz bus in 2:1 mode, enabling high-throughput packet processing while maintaining signal integrity on standard PCBs. The MPC866TCZP100A achieves this with optimized internal clock distribution and phase-locked loop synthesis that meets jitter specifications for synchronous serial interfaces like UTOPIA and MII.

Does the MPC866TCZP100A support IEEE 1149.1 JTAG debugging?

Yes, the MPC866TCZP100A includes a fully compliant IEEE 1149.1 test access port with TCK, TMS, TDO, TDI, and TRST_B pins. This enables boundary-scan testing, real-time on-chip emulation, and non-intrusive debug of both the PowerPC core and CPM subsystem - critical for validating complex protocol stacks during development of MPC866TCZP100A-based telecom hardware.

Can the MPC866TCZP100A operate with 5-V peripheral interfaces?

Yes, the MPC866TCZP100A has 5-V tolerant I/O pins including PA[0:15], PB[14:31], PC[4:15], PD[3:15], TDI, TDO, TCK, TRST_B, TMS, MII_TXEN, and MII_MDIO. These pins tolerate up to 5.5 V (but not more than 2.5 V above VDDH), allowing direct connection to legacy 5-V PHYs and logic without level-shifting circuitry - a key advantage in retrofitting MPC866TCZP100A into existing telecom chassis designs.

What memory types does the MPC866TCZP100A support natively?

The MPC866TCZP100A supports glueless interfacing to SDRAM, EDO DRAM, SRAM, EPROM, and flash memory through its eight-bank memory controller. Each bank allows independent configuration of wait states (0–30), CAS/WE timing, and boot chip-select width (8/16/32-bit), enabling flexible memory hierarchies in MPC866TCZP100A-based systems without external address latches or timing logic.

How many serial communication controllers (SCCs) does the MPC866TCZP100A include?

The MPC866TCZP100A includes four serial communication controllers (SCC1–SCC4), each configurable for HDLC, UART, IrDA, AppleTalk, or Ethernet MAC. SCC1 supports full IEEE 802.3 10-Mbps operation, while SCC4 optionally provides UTOPIA interface capability - making the MPC866TCZP100A uniquely suited for multi-protocol edge devices requiring concurrent ATM, Ethernet, and serial link termination.
