Product details
Overview
MC860ENCVR50D4R2 from Freescale Semiconductor is an MPC860EN variant of the PowerQUICC™ integrated communications controller, combining a 32-bit Power Architecture™ CPU core with a dedicated RISC communications processor module (CPM). It features 4 KB instruction and 4 KB data cache, supports up to four SCCs for HDLC/SDLC/Ethernet, and integrates Ethernet MAC, ATM UTOPIA interface, I²C, SPI, and PCMCIA controllers. It targets embedded networking gateways requiring deterministic real-time packet processing at 50 MHz system clock.
For engineers reviewing the MC860ENCVR50D4R2 datasheet, MC860ENCVR50D4R2 pinout, MC860ENCVR50D4R2 application, or MC860ENCVR50D4R2 equivalent, this page delivers verified technical context, package mapping, validated pin functions, key timing constraints, and two confirmed alternative parts for industrial router, DSLAM control, and telecom access node designs.
Technical Context
The MC860ENCVR50D4R2 implements a dual-processor architecture: a 32-bit Power Architecture CPU core with MMU, instruction/data caches, and a separate CPM handling serial protocols (HDLC, UART, IrDA, BISYNC) and time-critical I/O. Its 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.
It integrates IEEE 802.3-compliant 10/100 Mbps Ethernet MAC on SCC1–SCC4 (device-specific enablement), UTOPIA Level 1 ATM interface supporting AAL0/AAL5, four baud-rate generators, and a time-slot assigner (TSA) for T1/E1/PCM highway routing. The SIU provides PIT, RTC, watchdog, JTAG debug, and clock synthesis with PLL-based frequency multiplication.

Applications
| DSLAM Control Unit | Industrial Ethernet Gateway |
|---|---|
Use Scenario: Centralized control of multiple ADSL line cards in a DSL access multiplexer, managing configuration, statistics, and OAM cells. IC Role / Device Role / Timing Role: MC860ENCVR50D4R2 acts as the primary control processor, running Linux-based management software while its CPM handles ATM cell processing and UTOPIA framing. Use Value: Integrated UTOPIA and AAL5 support eliminates need for external ATM segmentation chips; 50-MHz operation meets real-time latency requirements for line card polling and alarm reporting. |
Use Scenario: Protocol translation between Modbus RTU field devices and EtherNet/IP control networks in factory automation. IC Role / Device Role / Timing Role: MC860ENCVR50D4R2 serves as dual-interface gateway controller-SCCs manage RS-485 Modbus links while Ethernet MAC handles TCP/IP stack and EtherNet/IP messaging. Use Value: On-chip dual-processor architecture isolates real-time serial protocol handling (CPM) from network stack processing (CPU), ensuring deterministic response under heavy network load. |
| Wireless Base Station Controller | T1/E1 Channel Bank |
Use Scenario: Baseband control unit in point-to-multipoint wireless infrastructure, coordinating TDMA frame scheduling and RF resource allocation. IC Role / Device Role / Timing Role: MC860ENCVR50D4R2 executes base station software and uses TSA + SMCs to manage TDM backhaul over E1 lines synchronized to GPS-derived timing. Use Value: TSA's 1-bit resolution and independent Tx/Rx routing enable precise alignment of uplink/downlink frames across multiple E1 spans without external timing ICs. |
Use Scenario: Aggregation of 24 DS0 channels into T1 or 30 B-channels into E1 for legacy PBX interconnection. IC Role / Device Role / Timing Role: MC860ENCVR50D4R2 functions as channel bank controller-SCCs handle HDLC framing, TSA routes time slots, and CPM performs CRC32 and bit stuffing in hardware. Use Value: Hardware-accelerated CRC and bit manipulation reduce CPU overhead to <5% during full T1/E1 traffic, enabling low-power fanless enclosure design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC860PZQ100D4 | 16 KB instruction + 8 KB data cache; same 357-pin PBGA; higher cache improves throughput in Linux kernel execution | Better suited for applications requiring larger OS footprint or frequent cache misses (e.g., firewall rule sets) | Select when sustained instruction fetch bandwidth exceeds 4 KB cache capacity; verify thermal margin due to higher typical power (851 mW @ 80 MHz vs. 656 mW @ 50 MHz for MC860ENCVR50D4R2) |
| MPC855TZQ100D4 | Single SCC (vs. four), no UTOPIA, adds USB 1.1 host; same CPU core, 4 KB/4 KB cache, 357-pin PBGA | Targeted at cost-sensitive edge routers with USB peripheral support but no ATM or multi-SCC requirements | Choose when UTOPIA and multi-SCC are unnecessary and USB host capability is required; note loss of Ethernet MAC flexibility and AAL5 offload |
Compared with MPC860PZQ100D4 and MPC855TZQ100D4, MC860ENCVR50D4R2 offers optimal balance of serial interface density, ATM support, and power efficiency for mid-tier telecom control applications-delivering full four-SCC and UTOPIA capability at lower thermal load than the P variant and broader protocol coverage than the 855T.

FAQ
What is the maximum operating frequency of the MC860ENCVR50D4R2?
The MC860ENCVR50D4R2 is rated for a 50 MHz system clock in 1:1 mode (CPU = bus speed). It supports 2:1 mode where the CPU runs at 100 MHz while the bus operates at 50 MHz. Operation above 50 MHz requires configuration of the PLL and adherence to voltage tolerances of 3.135–3.465 V for all supplies.
Does the MC860ENCVR50D4R2 include an integrated Ethernet MAC?
Yes, the MC860ENCVR50D4R2 includes a fully compliant IEEE 802.3/802.3u 10/100 Mbps Ethernet MAC implemented within its four Serial Communications Controllers (SCCs). SCC1–SCC4 can be configured for Ethernet operation, though device-specific programming determines which channels are enabled for this function.
What package type and pin count does the MC860ENCVR50D4R2 use?
The MC860ENCVR50D4R2 uses a 357-pin plastic ball grid array (PBGA) package with 25 mm × 25 mm body size and 1.27 mm pitch (package code ZQ/VR, case number 5058). Thermal performance depends on soldering thermal balls to the PCB ground plane per JEDEC JESD51-8 guidelines.
Can the MC860ENCVR50D4R2 support ATM cell processing?
Yes, the MC860ENCVR50D4R2 supports ATM cell processing via its UTOPIA Level 1 interface, compliant with ATM Forum UNI 4.0. It handles cell multiplexing/demultiplexing, AAL5 segmentation/reassembly, and APC scheduling for CBR/UBR traffic at up to 70 Mbps with a 50 MHz system clock.
What debug interfaces are available on the MC860ENCVR50D4R2?
The MC860ENCVR50D4R2 includes a full IEEE 1149.1 JTAG test access port (TAP) controller with eight hardware watchpoint comparators-four for instruction address, two for data address, and two for data value-enabling non-intrusive breakpoint setting and real-time trace in deployed systems.
