NXP Semiconductors KMPC860TVR80D4

Overview

KMPC860TVR80D4 from Freescale Semiconductor is a 32-bit Power Architecture™-based integrated communications controller (PowerQUICC™) combining a CPU core, CPM coprocessor, memory controller, Ethernet MAC, ATM interface, and multiple serial peripherals in a single PBGA357 package. It operates at up to 80 MHz CPU frequency with 4 KB instruction and 4 KB data cache, supports 10/100 Mbps IEEE 802.3u Ethernet, and targets embedded networking control applications such as DSLAMs, enterprise routers, and industrial gateways.

For engineers reviewing the KMPC860TVR80D4 datasheet, KMPC860TVR80D4 pinout, KMPC860TVR80D4 application, or KMPC860TVR80D4 equivalent, key selection considerations include its dual-bus architecture (CPU @ 80 MHz / bus @ 40 MHz), integrated FEC and UTOPIA ATM support, real-time clock, PCMCIA socket controller, and thermal design requirements for PBGA357 packaging in extended temperature industrial environments.

Technical Context

The KMPC860TVR80D4 implements a superscalar Power Architecture™ CPU core with MMU, 32-bit address/data buses, and dynamic bus sizing (8/16/32-bit). Its Communications Processor Module (CPM) offloads protocol processing via RISC-based coprocessor with 8 KB dual-port RAM, four SCCs, two SMCs, SPI, I²C, and TSA for TDM routing.

It integrates a full memory controller supporting DRAM, SRAM, Flash, and EPROM across eight banks with programmable wait states and boot-select options; supports IEEE 802.3u 10/100 Mbps Ethernet on SCC1–4 and ATM over UTOPIA Level 1 master interface compliant with UNI 4.0, including AAL0/AAL5, APC scheduler, and cell-level handshake.

FAQ

What is the maximum operating frequency of the KMPC860TVR80D4 CPU core?

The KMPC860TVR80D4 CPU core operates at up to 80 MHz. However, due to bus timing constraints, it must be configured in 2:1 mode - meaning the external bus clock runs at 40 MHz while the core runs at 80 MHz. This configuration is explicitly validated in the hardware specifications and reflected in the AC timing tables for 66-MHz-equivalent bus operation.

Does the KMPC860TVR80D4 support IEEE 802.3u 100 Mbps Ethernet?

Yes, the KMPC860TVR80D4 supports IEEE 802.3u 10/100 Mbps Ethernet via its SCC1–SCC4 serial controllers when configured as MAC interfaces. The hardware specification confirms full compliance, though simultaneous use of Ethernet and ATM over UTOPIA is prohibited - the device routes these functions to mutually exclusive pin groups.

What package type and thermal characteristics apply to the KMPC860TVR80D4?

KMPC860TVR80D4 uses a 357-ball PBGA package (case 5058, ZQ/VR designation) with 25 mm × 25 mm footprint and 1.27 mm pitch. Its thermal resistance is characterized as RθJB = 13°C/W on a 2s2p board, RθJA = 22°C/W under forced airflow (200 ft/min), and RθJC = 8°C/W - values critical for heatsink-less industrial designs operating at 95°C junction temperature.

Can the KMPC860TVR80D4 execute code directly from external Flash memory?

Yes, the KMPC860TVR80D4 memory controller supports direct execution from external Flash via its eight-bank interface. Boot-mode configuration allows selection of 8-, 16-, or 32-bit Flash devices on chip-select 0, with programmable wait states and write-protection per bank - enabling XIP (eXecute-In-Place) operation without copying to RAM.

How many serial communication channels does the KMPC860TVR80D4 integrate?

The KMPC860TVR80D4 integrates four Serial Communications Controllers (SCCs), two Serial Management Channels (SMCs), one SPI interface, and one I²C port. Each SCC supports multiple protocols including HDLC, UART, IrDA, and Ethernet MAC; the SMCs handle UART and GCI; SPI and I²C provide peripheral expansion - totaling nine independent serial I/O paths.
