NXP Semiconductors MPC860TVR50D4R2

Overview

MPC860TVR50D4R2 from NXP (formerly Freescale) is a PowerQUICC™ integrated communications controller combining a 32-bit Power Architecture™ CPU core and a dedicated RISC communications processor module (CPM). It operates at up to 50 MHz, integrates 4 KB instruction and 4 KB data caches, supports IEEE 802.3 10/100 Mbps Ethernet via SCCs, and features a 357-pin PBGA package with 3.3 V operation and 5 V-tolerant I/O. It targets embedded networking control in industrial gateways and telecom edge devices.

For engineers reviewing the MPC860TVR50D4R2 datasheet, MPC860TVR50D4R2 pinout, MPC860TVR50D4R2 application, or MPC860TVR50D4R2 equivalent, key selection considerations include its dual-core architecture (CPU + CPM), UTOPIA/ATM and FEC support, 32-bit bus timing at 50 MHz, thermal resistance (RθJA = 34°C/W), and compatibility with legacy PowerQUICC-based designs requiring extended temperature operation (–40°C to 95°C junction).

Technical Context

The MPC860TVR50D4R2 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 independent CPM executes protocol-specific communication functions (HDLC, UART, ATM, FEC) without CPU intervention. This enables deterministic real-time packet processing.

It supports multiple high-speed interfaces including four SCCs (configurable for Ethernet, HDLC, or IrDA), two SMCs, one SPI, one I²C, and a PCMCIA socket controller. The memory controller supports eight banks with dynamic bus sizing (8/16/32-bit), programmable wait states, and glueless interfacing to DRAM, SRAM, Flash, and EPROM.

FAQ

What is the maximum operating frequency of the MPC860TVR50D4R2?

The MPC860TVR50D4R2 is rated for a maximum system clock frequency of 50 MHz. In 1:1 mode (CPU clock = bus clock), this supports a 50 MHz bus interface with timing margins compliant to Table 7 of the hardware specification. Operation above 50 MHz is not supported; the MPC860TVR50D4R2 must not be configured for 66 MHz or 80 MHz modes.

Does the MPC860TVR50D4R2 support IEEE 802.3 100 Mbps Ethernet?

Yes, the MPC860TVR50D4R2 includes a fully compliant Fast Ethernet Controller (FEC) supporting 10/100 Mbps operation per IEEE 802.3u. It provides MII signals (TXD[0:3], RXD[0:3], TX_EN, CRS, COL, etc.) and management interface (MDC/MDIO) to connect to external PHYs such as the DP83848 or LAN8720A.

What package type and thermal characteristics apply to the MPC860TVR50D4R2?

The MPC860TVR50D4R2 uses a 357-pin PBGA package with ZQ/VR designation (Case No. 5058), 25 mm × 25 mm body, and 1.27 mm pitch. Its thermal resistance is RθJA = 34°C/W under natural convection on a single-layer board, and RθJB = 13°C/W junction-to-board - requiring thermal vias and ground plane connection beneath the package for reliable 50 MHz operation at 95°C junction temperature.

Can the MPC860TVR50D4R2 operate in extended temperature conditions?

Yes, the MPC860TVR50D4R2 is qualified for extended temperature operation from –40°C ambient to 95°C junction temperature. This is confirmed in Table 2 (Maximum Tolerated Ratings) and applies to all variants with 'T' suffix (e.g., MPC860TVR50D4R2), making it suitable for outdoor telecom cabinets and industrial control enclosures without forced cooling.

How does the CPM (Communications Processor Module) enhance real-time performance in the MPC860TVR50D4R2?

The CPM in the MPC860TVR50D4R2 is a dedicated RISC engine that offloads serial protocol processing (HDLC, UART, ATM, FEC) from the main CPU. It operates autonomously using its own 8 KB dual-port RAM and 16 SDMA channels, enabling deterministic frame handling with sub-10 µs interrupt latency - critical for time-sensitive industrial networking and telecom applications.
