NXP Semiconductors MPC866TZP133A

Overview

MPC866TZP133A from Freescale Semiconductor is a 32-bit PowerQUICC™ communications processor integrating a PowerPC core, CPM coprocessor, and Fast Ethernet controller in a single PBGA package. It operates at up to 133 MHz CPU frequency with 4-Kbyte instruction and 4-Kbyte data caches, 1.8-V core / 3.3-V I/O supply, and supports MII/UTOPIA interfaces for ATM and Ethernet applications in broadband access equipment.

For engineers reviewing the MPC866TZP133A datasheet, MPC866TZP133A pinout, MPC866TZP133A application, or MPC866TZP133A equivalent, key selection criteria include cache configuration (4K/4K), 357-pin PBGA package, 133-MHz operation in 2:1 bus mode, IEEE 802.3-compliant FEC, and ESAR-enhanced ATM support - all critical for embedded telecom control plane design.

Technical Context

The MPC866TZP133A implements a single-issue 32-bit PowerPC core with MMU, 32-entry ITLB/DTLB, and physically addressed caches. Its CPM subsystem includes 8-Kbyte dual-port RAM, 16 SDMA channels, four SCCs (all supporting serial ATM), and two SMCs - enabling concurrent HDLC, UART, and GCI protocols without microcode.

It integrates a system integration unit (SIU) with clock synthesizer, JTAG debug interface, software watchdog, and memory controller supporting DRAM, SDRAM, SRAM, and flash across eight banks. The FEC supports simultaneous MII (10/100Base-T) and UTOPIA Level 2 operation via multiplexed bus, with optional statistical cell counters and full-duplex master/slave UTOPIA capability.

FAQ

What is the maximum operating frequency of the MPC866TZP133A and how is bus timing configured?

The MPC866TZP133A operates at a maximum CPU frequency of 133 MHz. In this configuration, it must be run in 2:1 bus mode (66.5 MHz bus clock), as specified in Table 7 and Table 8 of the hardware specifications. Bus timing parameters - including setup/hold times and pulse widths - are defined in Table 9 for 33, 40, 50, and 66 MHz operation, with load conditions of 0 pF (min) and 50 pF (max). The MPC866TZP133A's memory controller supports programmable wait states per bank to accommodate varying memory speeds.

Does the MPC866TZP133A support IEEE 1149.1 JTAG debugging, and what debug features are included?

Yes, the MPC866TZP133A includes full IEEE 1149.1 test access port (TAP) support per Section 11 of the hardware specifications. It provides eight hardware comparators (four for instruction address, two for data address, two for data value), conditional breakpoint generation (=, ≠, <, >), and advanced on-chip emulation debug mode. These capabilities enable non-intrusive code inspection, real-time register tracing, and precise fault isolation during development of firmware for the MPC866TZP133A.

How does the MPC866TZP133A handle power supply sequencing, and what happens if violated?

The MPC866TZP133A requires strict sequencing: VDDL (core) must not exceed VDDH (I/O) during power-up or power-down, and both rails must stay within 1.7–1.9 V (VDDL/VDDSYN) and 3.135–3.465 V (VDDH). Violation forward-biases internal ESD protection diodes, causing excessive current flow that degrades long-term reliability. Figure 4 in the hardware specs shows an external diode-based sequencing circuit using MUR420 and 1N5820 diodes to enforce compliance for the MPC866TZP133A.

What peripheral interfaces are supported by the MPC866TZP133A for telecom applications?

The MPC866TZP133A supports MII (10/100Base-T), UTOPIA Level 2 (half/full-duplex), four SCCs with serial ATM capability, two SMCs, SPI, I²C, TSA for T1/E1/PCM routing, and PCMCIA socket interface. Its enhanced SAR (ESAR) mode adds OAM PM, multi-priority APC, and ATM port-to-port switching - all confirmed in Table 1 and Section 2 of the MPC866/MPC859 Hardware Specifications for the MPC866TZP133A.

Is the MPC866TZP133A pin-compatible with other members of the MPC866/859 family, and what are the key package constraints?

Yes, the MPC866TZP133A uses the same 357-pin PBGA package (27 × 27 mm, 1.27-mm pitch) as MPC866P, MPC866T, MPC859P, and MPC859T variants. Mechanical data in Section 15 confirms identical land pattern and thermal ball layout. However, functional pin assignments differ - e.g., MPC859DSL disables SCC2/SMC2 and TSA, while MPC866TZP133A retains all four SCCs and TSA. PCB layout must follow Section 9's four-layer board recommendation with dedicated VDD/GND planes for the MPC866TZP133A.
