Product details
Overview
KMPC860TCVR50D4 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) in a single PBGA357 package. It delivers 50 MHz system clock operation, 4 KB instruction/4 KB data cache, IEEE 802.3 10/100 Mbps Ethernet support via SCCs, and UTOPIA-level ATM cell processing up to 70 Mbps - deployed in carrier-grade DSLAMs, enterprise routers, and industrial protocol gateways.
For engineers reviewing the KMPC860TCVR50D4 datasheet, KMPC860TCVR50D4 pinout, KMPC860TCVR50D4 application, or KMPC860TCVR50D4 equivalent, this page provides verified technical context on its dual-core architecture, CPM offload capabilities, thermal limits (Tj max = 95°C), 3.3 V operation with 5 V-tolerant I/O, and BGA357 mechanical compatibility for legacy PowerQUICC-based board refreshes.
Technical Context
The KMPC860TCVR50D4 implements a superscalar 32-bit Power Architecture™ CPU core with MMU, 4 KB instruction and 4 KB data caches, and a separate RISC-based Communications Processor Module (CPM) handling serial protocols independently. 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 PCMCIA.
It integrates four Serial Communications Controllers (SCCs) supporting HDLC, UART, IrDA, and Ethernet MAC functions; two Serial Management Channels (SMCs); one SPI; one I²C port; a Time-Slot Assigner (TSA); and IEEE 1149.1 JTAG debug interface - all synchronized to a 50 MHz system clock with PLL-derived internal clocks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 32-bit Power Architecture™ CPU with MMU, 32 GPRs, branch prediction, and conditional prefetch |
| System Clock Speed | 50 MHz - enables full-speed Ethernet MAC operation and ATM cell processing at ≤70 Mbps |
| Cache Configuration | 4 KB instruction cache + 4 KB data cache - two-way set-associative, physically addressed, lockable per block |
| Memory Controller | Eight-bank controller supporting DRAM, SRAM, Flash, EPROM, and PCMCIA - no external glue logic required |
| I/O Voltage | 3.3 V core supply (VDDH/VDDL), 5 V-tolerant inputs except EXTAL/EXTCLK - simplifies mixed-voltage board design |
| Thermal Limit | Junction temperature max = 95°C - requires thermal management on 4-layer boards with RθJB = 13°C/W |

Pinout & Package
KMPC860TCVR50D4 is housed in a 357-ball plastic ball grid array (PBGA) package per case number 5058 (1103D-02), designated ZQ/VR. The package features 25×25 mm footprint, 1.27 mm ball pitch, and exposed thermal pad for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| Dual-processor architecture | CPU handles OS/application tasks while CPM independently manages serial protocols - eliminates host CPU polling overhead |
| Four SCCs with Ethernet MAC | Each SCC supports IEEE 802.3 10/100 Mbps MAC layer - enables multi-port routing without external PHYs |
| UTOPIA ATM interface | Supports ATM Forum UNI 4.0 - enables CBR/UBR scheduling and AAL5 segmentation/reassembly for DSL backhaul |
| PCMCIA socket controller | Two-slot, Release 2.1-compliant interface - allows hot-pluggable WAN modules (e.g., T1/E1 cards) without FPGA glue logic |
| Low-power operating modes | Doze/Sleep/Deep Sleep modes reduce power by disabling non-essential blocks - preserves RTC and PIT during standby |
Applications
| DSLAM Line Card | Industrial Protocol Gateway |
|---|---|
Use Scenario: Aggregating ADSL2+ subscriber traffic into ATM cells for metro aggregation. IC Role / Device Role / Timing Role: KMPC860TCVR50D4 acts as line card controller - runs Linux, terminates PPPoE, performs ATM segmentation via CPM, and drives UTOPIA PHYs.

Use Value: Simultaneous dual-protocol handling with deterministic latency - leverages hardware HDLC and Ethernet MAC to meet <10 ms cycle time requirements. |
| Carrier-Grade Router | Secure Remote Terminal Unit (RTU) |
Use Scenario: Edge routing in telecom POPs with QoS-aware packet forwarding and firewall services. IC Role / Device Role / Timing Role: KMPC860TCVR50D4 functions as control plane processor - executes routing daemons, manages ACL tables in MMU-protected memory, and schedules traffic via TSA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC860PZQ50D4 | 16 KB instruction / 8 KB data cache; same 50 MHz speed and PBGA357 package | Better suited for complex routing stacks requiring larger instruction cache - e.g., IPv6 forwarding with deep packet inspection | Select when application demands >4 KB instruction cache headroom and maintains identical pinout and thermal profile |
| MPC855TZQ50D4 | Single SCC (vs. four), no ATM/UTOPIA, adds USB 1.1 host - same CPU core and 50 MHz speed | Targeted at cost-sensitive embedded networking where Ethernet-only connectivity suffices and USB peripheral support is needed | Choose when reducing serial channel count and adding USB outweighs loss of ATM/SCC flexibility |
Compared with KMPC860TCVR50D4, MPC860PZQ50D4 offers higher cache bandwidth for memory-intensive routing, while MPC855TZQ50D4 trades SCC/ATM capability for USB integration - both retain identical 50 MHz timing, 3.3 V operation, and PBGA357 mechanical fit for drop-in evaluation.

FAQ
What is the maximum junction temperature specification for KMPC860TCVR50D4?
The KMPC860TCVR50D4 has a maximum junction temperature (Tj) of 95°C under extended temperature conditions. This limit applies regardless of ambient temperature range (–40°C to +85°C) and must be maintained through proper thermal design - including use of a 4-layer PCB with ground/power planes and adherence to RθJB = 13°C/W per JEDEC JESD51-8.
Does KMPC860TCVR50D4 support IEEE 802.3 100 Mbps Ethernet natively?
Yes, KMPC860TCVR50D4 supports full IEEE 802.3u 100 Mbps Ethernet via its SCCs when configured in MII mode. The CPM handles MAC-layer functions including CRC generation, preamble insertion, and collision detection - enabling wire-speed operation at 50 MHz system clock without host CPU intervention.
What package type and ball count does KMPC860TCVR50D4 use?
KMPC860TCVR50D4 uses a 357-ball plastic BGA (PBGA) package with 25 mm × 25 mm body size, 1.27 mm ball pitch, and case number 5058 (1103D-02), designated ZQ/VR. It includes an exposed thermal pad on the underside for improved heat conduction to the PCB.
Can KMPC860TCVR50D4 operate with a 3.0 V supply voltage?
KMPC860TCVR50D4 supports 3.0 V minimum supply voltage only at frequencies ≤40 MHz. At its rated 50 MHz speed, the device requires VDDH/VDDL between 3.135 V and 3.465 V per DC electrical specifications - operating below 3.135 V risks timing violations and functional failure.
Is KMPC860TCVR50D4 pin-compatible with other MPC860 variants like MPC860PZQ50D4?
Yes, KMPC860TCVR50D4 is pin-compatible with MPC860PZQ50D4 and other ZQ/VR-packaged MPC860 variants (e.g., MPC860DP, MPC860T). All share identical 357-ball PBGA layout, power sequencing, and signal definitions - enabling direct replacement where cache or peripheral differences are acceptable.
