Product details
Overview
KMPC860SRCVR50D4 from Freescale Semiconductor is a 32-bit Power Architecture™-based integrated communications controller (PowerQUICC™) combining RISC CPU core and Communications Processor Module (CPM) in a single PBGA357 package. It operates at up to 50 MHz, integrates 4 KB instruction and 4 KB data cache, IEEE 802.3-compliant 10/100 Mbps Ethernet MAC, four SCCs, two SMCs, I²C, SPI, and UTOPIA ATM interface - deployed in telecom edge routers and industrial protocol gateways.
For engineers reviewing the KMPC860SRCVR50D4 datasheet, KMPC860SRCVR50D4 pinout, KMPC860SRCVR50D4 application, or KMPC860SRCVR50D4 equivalent, key selection criteria include its 50 MHz system clock rating, 3.3 V core/I/O operation with 5 V-tolerant inputs (except EXTAL/EXTCLK), dual-bus architecture supporting DRAM/SRAM/Flash, and integrated real-time clock and JTAG debug interface.
Technical Context
The KMPC860SRCVR50D4 implements a superscalar-capable Power Architecture CPU core with MMU, 32×32-bit GPRs, and branch prediction logic, paired with a dedicated RISC-based CPM handling serial protocols independently. Its memory controller supports eight banks with programmable wait states, dynamic bus sizing (8/16/32-bit), and glueless interfacing to DRAM, SRAM, EPROM, and Flash.
It features four Serial Communications Controllers (SCCs) supporting HDLC/SDLC, UART, IrDA, BISYNC, and Ethernet MAC (on SCC1–4); two Serial Management Channels (SMCs); UTOPIA Level 1 ATM interface compliant with UNI 4.0; and time-slot assigner (TSA) for T1/E1/PCM multiplexing - all synchronized via shared CPM dual-port RAM and SDMA channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC860T | Same die revision (D.4), identical 50 MHz speed grade, but offered in ZP (0.9 mm height) PBGA vs. KMPC860SRCVR50D4's ZQ/VR (1.2 mm height) package | No functional difference; ZP variant has lower thermal resistance (RθJA = 34°C/W vs. 22°C/W on 4-layer board) but reduced mechanical clearance | Select MPC860T only if board stack-up requires thinner package; otherwise KMPC860SRCVR50D4 offers superior thermal performance. |
| MPC860P | Higher cache (16 KB instruction / 8 KB data), same 50 MHz rating, identical ZQ/VR package; supports larger code footprints and complex protocol stacks | Better suited for Linux-based routing or multi-protocol convergence where CPM offload + larger cache reduces CPU load | Choose MPC860P when application demands >1 MB of cached code/data; KMPC860SRCVR50D4 remains optimal for cost-sensitive, fixed-function deployments. |
Compared with MPC860T and MPC860P, KMPC860SRCVR50D4 delivers balanced performance for deterministic communications workloads - matching MPC860T's thermal profile while retaining MPC860P's UTOPIA/ATM feature set at lower BOM cost and smaller cache footprint.

FAQ
What is the maximum operating frequency of the KMPC860SRCVR50D4?
The KMPC860SRCVR50D4 is rated for a maximum system clock frequency of 50 MHz in 1:1 mode (CPU = bus). It supports 2:1 mode (CPU at 100 MHz, bus at 50 MHz) only on higher-speed variants; this specific speed grade is validated at 50 MHz for both CPU and bus domains per Freescale Hardware Spec Rev. 10.
Does the KMPC860SRCVR50D4 include an integrated Ethernet PHY?
No, the KMPC860SRCVR50D4 integrates only the Media Access Control (MAC) layer for 10/100 Mbps Ethernet. External PHY devices (e.g., DP83848) must be used for physical layer signaling. The SCC1–SCC4 pins provide MII/RMII-compatible signals requiring external PHY connection.
What package type and dimensions does the KMPC860SRCVR50D4 use?
The KMPC860SRCVR50D4 uses a 357-ball plastic BGA (PBGA) package with ZQ/VR designation (Freescale case number 5058), measuring 25 mm × 25 mm with 1.27 mm ball pitch and 1.2 mm body height. Thermal resistance is specified as RθJA = 22°C/W on a 4-layer PCB.
Can the KMPC860SRCVR50D4 support both ATM and Ethernet simultaneously?
Yes, but with functional restriction: IEEE 802.3u 10/100 Mbps Ethernet operation is disabled when the UTOPIA interface is configured for ATM. The KMPC860SRCVR50D4 supports either Ethernet MAC mode (via SCCs) or UTOPIA ATM mode - not both concurrently - due to shared resource allocation in the CPM and pin multiplexing.
What debug interfaces are available on the KMPC860SRCVR50D4?
The KMPC860SRCVR50D4 includes full IEEE 1149.1 (JTAG) test access port with TCK, TMS, TDI, TDO, and TRST pins. It supports advanced on-chip emulation with eight hardware watchpoint comparators - four for instruction address, two for data address, and two for data value - enabling precise breakpoint and trace capabilities during firmware development.
