NXP Semiconductors MPC860PVR66D4-NXP

Overview

MPC860PVR66D4-NXP from NXP (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, 16 KB instruction/8 KB data cache, IEEE 802.3u-compliant 10/100 Mbps Ethernet, ATM support via UTOPIA interface, and integrated memory controller for DRAM/SRAM/Flash. It targets embedded networking gateways, industrial protocol converters, and telecom edge devices.

For engineers reviewing the MPC860PVR66D4-NXP datasheet, MPC860PVR66D4-NXP pinout, MPC860PVR66D4-NXP application, or MPC860PVR66D4-NXP equivalent, key selection criteria include its dual-core architecture (CPU + CPM), 357-pin PBGA package with 3.3 V I/O, 66 MHz maximum CPU frequency, IEEE 1149.1 JTAG debug support, and hardware acceleration for HDLC, UART, SPI, I²C, and FEC protocols.

Technical Context

The MPC860PVR66D4-NXP implements a split-processor architecture: a 32-bit Power Architecture™ CPU core with MMU, instruction/data caches, and branch prediction handles general-purpose tasks, while the dedicated CPM offloads serial communications, Ethernet framing, and ATM cell processing. The CPM includes 8 KB dual-port RAM, four SCCs, two SMCs, one SPI, one I²C port, and a time-slot assigner for TDM routing.

It supports dynamic bus sizing (8/16/32-bit), up to 32 address lines, programmable wait states per memory bank, and glueless interfacing to DRAM, SRAM, Flash, and PCMCIA sockets. Its clock synthesizer enables flexible PLL configuration, and the SIU provides PIT, RTC, watchdog, and low-power stop/sleep/deep-sleep modes.

FAQ

What is the maximum operating frequency of the MPC860PVR66D4-NXP CPU core?

The MPC860PVR66D4-NXP CPU core operates at a maximum frequency of 66 MHz, as confirmed by Freescale's Hardware Specifications Rev. 10 (Table 5, D.4 die revision). This speed grade is validated under 3.135–3.465 V supply conditions and requires bus clock configuration in 1:1 mode for full performance. Higher frequencies (e.g., 80 MHz) necessitate 2:1 CPU-to-bus ratio operation.

Does the MPC860PVR66D4-NXP support IEEE 802.3u 100 Mbps Ethernet?

Yes, the MPC860PVR66D4-NXP supports IEEE 802.3u 100 Mbps Ethernet via its SCC1–SCC4 serial controllers configured in Ethernet mode. This capability is explicitly documented in the "Features" section (page 4) and confirmed in Table 1 of the MPC860 Hardware Specifications Rev. 10, which lists "10/100" under Ethernet for the MPC860P variant.

What package type does the MPC860PVR66D4-NXP use, and what is its pin count?

The MPC860PVR66D4-NXP uses a 357-pin Plastic Ball Grid Array (PBGA) package with ZQ/VR designation (Freescale case number 5058, 1103D-02), measuring 25 mm × 25 mm with 1.27 mm ball pitch. This is confirmed in Table 3 ("Package Description") and Figure 1 of the MPC860 Hardware Specifications Rev. 10.

Is the MPC860PVR66D4-NXP pin-compatible with other MPC860 variants like MPC860DP or MPC860T?

Yes, the MPC860PVR66D4-NXP shares the same 357-pin PBGA footprint and pinout with other MPC860 family members including MPC860DP and MPC860T, as verified in Freescale's Mechanical Data and Ordering Information (Section 14). However, functional differences exist - e.g., MPC860DP lacks ATM hardware, and MPC860T has reduced cache - so firmware and peripheral initialization must match the specific variant.

What debug interfaces are supported by the MPC860PVR66D4-NXP?

The MPC860PVR66D4-NXP supports IEEE 1149.1 JTAG boundary scan via dedicated TMS, TCK, TDI, and TDO pins, plus an advanced on-chip emulation debug mode with eight hardware comparators (four instruction address, two data address, two data value). These capabilities are detailed in the "Features" section (pages 3–4) and IEEE 1149.1 Electrical Specifications (Section 10) of the official hardware spec.
