MPC860SRZQ80D4 - 80MHz PowerQUICC MPU, 357-PBGA | NXP
MPN: MPC860SRZQ80D4 ✗ پایان تولیدMPC860SRZQ80D4 نمای کلی
A microprocessor (MPU) is an integrated circuit that contains the arithmetic logic unit, control unit, register file, and memory interfaces of a computer on a single die. In system hierarchy, an MPU sits above microcontrollers in complexity, requiring external memory and peripherals, and is used in applications where high-throughput processing and flexible memory architectures are required. The PowerQUICC MPC860 family specifically targets telecommunications and networking, where the integrated CPM offloads communications processing from the main CPU.
Key differentiating features of the MPC860SRZQ80D4 include the integrated CPM with two serial communications controllers (SCCs), two serial management controllers (SMCs), one serial peripheral interface (SPI), and an I2C controller, plus a 10/100 Mbps Ethernet MAC. The device supports 32-bit PowerPC architecture with separate instruction and data MMUs, providing virtual memory support for embedded operating systems such as VxWorks and Linux. 80 MHz core speed delivers 50 MIPS Dhrystone performance, sufficient for mid-tier routing, switching, and industrial control workloads.
Architecturally, the MPC860SRZQ80D4 separates the PowerPC core from the CPM via an internal bus, allowing protocol processing to occur in parallel with CPU tasks. The 357-PBGA package uses a 1.27 mm ball pitch and is suitable for surface-mount assembly with a thermal vias under the die for heat dissipation.
Typical applications include WAN routers, ISDN terminal adapters, Fast Ethernet switches, industrial automation embedded in legacy telecom equipment, and military/aerospace systems requiring the PowerPC architecture. The wide protocol support also makes it suitable for industrial serial concentrators and protocol converters.
Designers should note that the MPC8xx family requires external SDRAM, flash, and glue logic, and the BGA package requires X-ray inspection and controlled-impedance PCB stackup. The 3.3 V I/O simplifies interfacing to 5 V tolerant peripherals via external level shifters.

کاربردهای معمول
MPC860SRZQ80D4 مناسب است برای 6 کاربردs: WAN Router / Edge Networking, ISDN Terminal Adapter, Fast Ethernet Switch Controller, Industrial Protocol Converter / Gateway, Legacy Telecom Equipment Maintenance, Aerospace and Defense Embedded Controller.
WAN Router / Edge Networking
The MPC860SRZQ80D4's 80 MHz PowerPC core plus integrated CPM with 10/100 Ethernet MAC and dual SCCs make it well-suited to mid-tier WAN router and edge-networking designs. The CPM offloads PPP, frame relay, and HDLC protocol processing in parallel with CPU tasks, sustaining wire-speed serial throughput even at 50 MIPS Dhrystone. Placing this part between the WAN PHY and the Ethernet switch fabric, designers reuse VxWorks or pSOS+ BSPs originally authored for PowerQUICC platforms. Unlike soft-CPU implementations, the integrated CPM consumes near-zero CPU cycles, freeing the PowerPC core for routing-table maintenance and management-plane tasks.
پیشنهادی
ISDN Terminal Adapter
The MPC860SRZQ80D4 is widely deployed in legacy ISDN terminal adapters where the integrated CPM's two SCCs handle the ISDN BRI/U-interface D-channel and B-channel aggregation. The 80 MHz core performs HDLC framing and call-control state machines while the CPM manages bit-level signaling. With 3.3 V I/O simplifying interface to ISDN transceiver ICs, this part minimizes external glue logic. Designers reduce PCB area by integrating what previously required a discrete serial controller plus an external Ethernet MAC.
پیشنهادی
Fast Ethernet Switch Controller
In Fast Ethernet switches the MPC860SRZQ80D4 acts as the management-plane and Layer-3 forwarding CPU. The integrated 10/100 MAC provides one uplink, while the dual SCCs connect to a PHY or a switch fabric via MII/RMII. 80 MHz core throughput is sufficient to maintain forwarding tables and run SNMP/CLI management without compromising line-speed switching. The 357-PBGA package accommodates high-density board designs, while the 1.27 mm ball pitch remains manufacturable on standard 4-layer PCBs.
پیشنهادی
Industrial Protocol Converter / Gateway
Industrial gateways convert between serial fieldbuses (Modbus, Profibus, CANopen) and Ethernet, and the MPC860SRZQ80D4's mix of SCCs, SMCs, SPI, and I2C accommodates multiple legacy protocols simultaneously. The 32-bit PowerPC core runs protocol stacks and conversion logic, while the CPM hardware-accelerates bit-level framing. The -40C to +95C operating temperature range supports factory-floor deployment. Unlike microcontroller-based gateways, this MPU delivers the throughput to run multiple concurrent protocol conversions at full line rate.
پیشنهادی
Legacy Telecom Equipment Maintenance
For maintenance of installed telecom bases that originally shipped with PowerQUICC silicon, the MPC860SRZQ80D4 serves as a like-for-like service replacement, allowing field technicians to repair legacy equipment without requalification. The 357-PBGA (25x25) footprint and pinout match the original assembly, and the 80 MHz performance matches the original deployed units. This avoids costly PCB redesign when individual units fail in service. Franchised distributors such as Rochester Electronics maintain authorized stock of these NRND parts for service continuity.
پیشنهادی
Aerospace and Defense Embedded Controller
The MPC860SRZQ80D4 is used in aerospace and defense embedded controllers where its 32-bit PowerPC architecture, integrated CPM, and 357-PBGA package meet long-lifecycle military program requirements. The integrated Ethernet and serial controllers reduce BOM count in size- and weight-constrained applications. The -40C to +95C industrial operating range supports many defense environments. Designers benefit from the mature VxWorks and pSOS+ BSP ecosystems, which are well-validated for mission-critical avionics and C4ISR platforms. The 80 MHz core is sufficient for low-bandwidth data acquisition and discrete-control tasks.

یادداشت‌های طراحی
The 357-PBGA package with 1.27 mm ball pitch requires 4-layer PCB minimum with controlled-impedance stackup and a continuous ground plane beneath the BGA. Thermal vias under the die (9-12 vias in a 3x3 array, 0.3 mm drill) reduce theta_JA. PCB layout must route high-speed Ethernet MII traces with 50 ohm impedance and length matching within 50 mils on the differential pairs. Decoupling capacitors must be placed within 100 mils of each supply pin per the hardware specifications document.
Estimated: at 80 MHz core clock and 3.3 V supply with typical CPM and CPU utilization, the MPC860SRZQ80D4 dissipates approximately 1.0-1.5 W. The 357-PBGA package requires thermal vias under the die and adequate copper pour on top and inner layers to maintain junction temperature below 125 C. Industrial applications at +95 C ambient need verified thermal design.
The MPC8xx family requires external SDRAM, flash, and bus-arbiter glue logic. Do not assume internal flash exists. JTAG boundary-scan must be accessible for board test; route TCK/TMS/TDO/TDI to a test header. The 3.3 V I/O is NOT 5 V tolerant; use external level shifters when interfacing to 5 V peripherals. Lead-bearing solder balls require exemptions or non-RoHS assembly flow.
Place external SDRAM as close to the MPC860SRZQ80D4 data bus pins as possible, keeping trace lengths under 50 mm and matched within 25 mils across byte lanes. The 32-bit external data bus and address bus run at 80 MHz, so controlled impedance (50 ohm) is mandatory. Isolate analog PLL power supply pins with ferrite beads and dedicated decoupling; PLL jitter directly impacts CPM bit-error performance.
The integrated 10/100 Ethernet MAC MII/RMII signals run at 25 MHz (MII) or 50 MHz (RMII) and must be length-matched and impedance-controlled. Series-source termination of 33 ohm on MII clock and data lines reduces ringing. The SCC serial outputs can drive long traces to PHY or transceiver ICs without additional buffering, but impedance discontinuities at connector transitions must be minimized.
