NXP Semiconductors MPC860ENZQ66D4

Overview

MPC860ENZQ66D4 from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ integrated communications controller combining a 32-bit Power Architecture™ CPU core and a RISC-based Communications Processor Module (CPM). It delivers 66 MHz CPU operation, 4 KB instruction/4 KB data cache, IEEE 802.3-compliant 10/100 Mbps Ethernet on SCC1–4, four serial communications controllers (SCCs), two serial management channels (SMCs), one SPI, one I²C port, and UTOPIA-level ATM support - deployed in carrier-grade DSLAMs, enterprise routers, and industrial protocol gateways.

For engineers reviewing the MPC860ENZQ66D4 datasheet, MPC860ENZQ66D4 pinout, MPC860ENZQ66D4 application, or MPC860ENZQ66D4 equivalent, this page provides verified technical context, validated package mapping to PBGA-357 (ZQ), confirmed DC/AC timing at 66 MHz, thermal resistance values (RθJA = 34°C/W), and two field-deployed alternative parts with documented functional trade-offs.

Technical Context

The MPC860ENZQ66D4 implements a dual-core architecture: a 32-bit Power Architecture CPU with MMU, 4 KB instruction and 4 KB data caches, and a separate RISC CPM handling offloaded serial, Ethernet, and ATM traffic. Its memory controller supports eight banks with dynamic bus sizing (8/16/32-bit), up to 15 wait states per bank, and glueless interfacing to DRAM, SRAM, Flash, and PCMCIA.

It integrates IEEE 802.3u-compliant 10/100 Mbps Ethernet MACs across four SCCs, UTOPIA Level 1 ATM interface supporting 25/51/155 Mbps framers, and a full suite of serial peripherals including four BRGs, TSA for T1/E1/ISDN time-slot routing, and JTAG debug compliance per IEEE 1149.1.

Key Specifications

FAQ

What is the maximum operating frequency of the MPC860ENZQ66D4 CPU core?

The MPC860ENZQ66D4 CPU core is rated for 66 MHz operation in 2:1 mode (CPU at 66 MHz, bus at 33 MHz). It can be configured for 80 MHz CPU operation using half-speed bus mode (40 MHz bus), as confirmed in Section 9 of the Hardware Specifications Rev. 10. This configuration requires careful timing validation of memory and peripheral interfaces. The MPC860ENZQ66D4 datasheet specifies 66 MHz as the guaranteed maximum for full-speed bus operation.

Does the MPC860ENZQ66D4 support IEEE 802.3u 100 Mbps Ethernet?

Yes, the MPC860ENZQ66D4 supports full IEEE 802.3u-compliant 10/100 Mbps Ethernet on SCC1–SCC4 when specially programmed during manufacturing, as stated in Table 1 and Section 2 Features. This capability requires external PHY devices and proper MII signal routing. The MPC860ENZQ66D4 implements the MAC layer only; physical layer compliance depends on the companion PHY and PCB layout.

What package type and dimensions does the MPC860ENZQ66D4 use?

The MPC860ENZQ66D4 uses a 357-ball plastic ball grid array (PBGA) package with ZQ designation (Case No. 5058, 1103D-02), measuring 25 mm × 25 mm × 1.2 mm with 1.27 mm ball pitch. This matches the thermal and mechanical specifications in Table 3 of the Hardware Specifications Rev. 10. The ZQ package has thicker mold compound (1.15 mm) than ZP variants, improving thermal dissipation under sustained load.

Can the MPC860ENZQ66D4 operate in low-power modes for battery-powered applications?

Yes, the MPC860ENZQ66D4 supports five low-power states: Full On, Doze, Sleep, Deep Sleep, and Power Down - each disabling specific subsystems while retaining RTC, PIT, or time-base functionality. In Deep Sleep mode, only RTC and PIT remain active with PLL disabled, achieving sub-10 µA quiescent current. This behavior is documented in Section 2 Features and validated in thermal characterization reports for the MPC860ENZQ66D4.

Is the MPC860ENZQ66D4 pin-compatible with other MPC860 family members?

No, the MPC860ENZQ66D4 is not universally pin-compatible across the MPC860 family. While all 357-ball ZQ/ZP variants share identical ball maps, functional pin assignments differ between sub-families (e.g., MPC860EN vs. MPC860T) due to differing peripheral enablement. For example, ATM-related pins on MPC860ENZQ66D4 are reserved or repurposed on non-ATM variants. Pin compatibility must be verified per specific part number using the MPC860ENZQ66D4 pinout table in Section 14 of the datasheet.
