Product details
Overview
MPC860DPVR66D4 from NXP (formerly Freescale) is a PowerQUICC™ integrated communications controller combining a 32-bit Power Architecture™ CPU core with a dedicated RISC-based Communications Processor Module (CPM), supporting up to 66 MHz CPU operation, 16 KB instruction / 8 KB data cache, IEEE 802.3u 10/100 Mbps Ethernet, and ATM UTOPIA Level 1 interface - deployed in carrier-grade DSLAMs, enterprise routers, and industrial protocol gateways.
For engineers reviewing the MPC860DPVR66D4 datasheet, MPC860DPVR66D4 pinout, MPC860DPVR66D4 application, or MPC860DPVR66D4 equivalent, this page delivers verified package mapping (PBGA-357 ZQ/VR), confirmed thermal resistance (RθJA = 34°C/W), validated bus timing at 66 MHz, and two field-proven alternative parts for migration planning in legacy PowerQUICC-based networking hardware.
Technical Context
The MPC860DPVR66D4 implements a dual-engine architecture: a 32-bit Power Architecture CPU core with MMU, 4-/16-KB instruction cache, and 4-/8-KB data cache; plus a separate CPM executing HDLC, UART, SPI, I²C, and FEC protocols independently. It supports dynamic bus sizing (8/16/32-bit), 32 address lines, and glueless interfacing to DRAM, SRAM, Flash, and PCMCIA sockets.
Its system integration unit includes a programmable clock synthesizer, real-time clock, IEEE 1149.1 JTAG debug interface, four 16-bit timers (or two 32-bit), and low-power modes (Doze, Sleep, Deep Sleep, Power Down). The CPM integrates 8 KB dual-port RAM, 16 SDMA channels, and time-slot assigner (TSA) for T1/E1/ISDN multiplexing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC860PZP66D4 | ZP package (0.85 mm mold compound), RθJA = 34°C/W (same thermal rating), identical electrical specs | No PCB redesign needed - same 357-ball layout but thinner package height (0.9 mm vs 1.2 mm) | Select for space-constrained modules where ZQ/VR height exceeds mechanical envelope |
| MPC855TZP80D4 | Higher 80 MHz CPU, 4 KB I/D cache only, no ATM support, adds USB 1.1 host controller | Suitable for IP-only edge devices; lacks UTOPIA and AAL5 acceleration - requires software ATM emulation | Choose when migrating from ATM to pure IP infrastructure and higher throughput is critical |
Compared with MPC860DPVR66D4, MPC860PZP66D4 offers identical functionality in a lower-profile package for height-sensitive telecom blades, while MPC855TZP80D4 trades ATM offload for higher CPU speed and USB - requiring architectural changes to replace hardware-accelerated cell processing.

FAQ
What is the maximum operating frequency of the MPC860DPVR66D4?
The MPC860DPVR66D4 is rated for a maximum CPU frequency of 66 MHz. At this speed, it requires VDDH/VDDL = 3.135–3.465 V and supports bus operation in 1:1 mode (66 MHz bus). Operation above 66 MHz is not supported - the MPC860DPVR66D4 datasheet explicitly limits CPU frequency to 66 MHz for this revision (D.4 die).
Does the MPC860DPVR66D4 support IEEE 802.3u 100 Mbps Ethernet?
Yes, the MPC860DPVR66D4 supports full-duplex 10/100 Mbps Ethernet compliant with IEEE 802.3u on its SCC1–SCC4 serial controllers. This capability is enabled in hardware and does not require external PHY arbitration logic - the MAC layer is fully integrated within the CPM.
What package type is used for the MPC860DPVR66D4?
The MPC860DPVR66D4 uses a 357-ball plastic ball grid array (PBGA) package with ZQ/VR case code (5058, 1103D-02), measuring 25 mm × 25 mm with 1.27 mm ball pitch and 1.2 mm height. This matches the thermal and mechanical specifications in Table 3 of the MPC860 Hardware Specifications Rev. 10.
Can the MPC860DPVR66D4 operate in low-power modes?
Yes, the MPC860DPVR66D4 supports five low-power modes: Full On, Doze, Sleep, Deep Sleep, and Power Down. In Deep Sleep mode, only RTC and PIT remain active - core, CPM, PLL, and memory controller are disabled, reducing current draw to under 100 µA while preserving real-time clock accuracy.
Is the MPC860DPVR66D4 pin-compatible with other MPC860 variants?
The MPC860DPVR66D4 shares the same 357-ball PBGA footprint and pinout with all MPC860 family members in ZQ/VR packaging (e.g., MPC860T, MPC860P, MPC860EN). Signal assignments, power/ground ball locations, and JTAG interface are identical - enabling drop-in replacement where functional features align.
