MPC860SRCZQ5 概要
What is a PowerQUICC microprocessor? PowerQUICC is a family of integrated communications microprocessors originally developed by Motorola/Freescale (now NXP Semiconductors) that combines a PowerPC processor core with a separate Communications Processor Module (CPM). The CPM offloads serial protocol handling (Ethernet, HDLC, UART, SPI, I2C) from the main CPU, enabling deterministic real-time I/O performance. Within the broader taxonomy, the MPC860 sits at the intersection of microprocessor -> embedded MPU -> communications MPU -> industrial networking SoC.
Key features of the MPC860SRCZQ5 include a 50 MHz core frequency, 32-bit PowerPC architecture, 4 KB instruction cache / 4 KB data cache, integrated CPM with two SCCs, two SMCs, one SPI, one I2C, and a 10/100 Ethernet MAC option via the Fast Ethernet Controller (FEC) on some derivatives. The 357-PBGA (25x25 mm) package provides extensive I/O for embedded backplane and telecom hardware designs.
The MPC860 architecture separates the core (general-purpose integer and load/store engine) from the CPM (RISC-based DMA-driven protocol engine), allowing telecom and industrial designs to run protocol stacks without taxing the host CPU. This dual-processor approach was pioneering in the late 1990s and remains in service in legacy DSLAMs, industrial routers, and avionics controllers.
Typical applications include ISDN terminal adapters, DSL access multiplexers, T1/E1 multiplexers, industrial Ethernet bridges, serial-to-Ethernet gateways, and legacy telecom switching equipment. The wide operating temperature range and rugged PBGA package suit harsh industrial environments.
When designing with the MPC860SRCZQ5, ensure proper thermal management via thermal vias under the die-side pad, follow NXP's MPC860 hardware specifications for bus arbitration timing, and use the integrated CPM descriptor rings for zero-CPU-overhead DMA. Mind the 3.3V I/O and 2.5V/3.3V core power sequencing requirements.

主な用途
MPC860SRCZQ5 の用途: 6 件s: ISDN Terminal Adapters and DSL Modems, Industrial Ethernet Bridges and Gateways, T1/E1 Multiplexers and Telecom Equipment, Legacy Avionics and Defense Controllers, Point-of-Sale and ATM Networking, Set-Top Box and Cable Modem Headends.
ISDN Terminal Adapters and DSL Modems
The MPC860SRCZQ5's integrated Communications Processor Module (CPM) with two SCCs makes it ideal for ISDN terminal adapters and early DSL modems. The PowerPC core runs protocol management and signaling stacks, while the CPM's HDLC controllers handle the raw ISDN D-channel and B-channel data without host CPU intervention. The 50 MHz core provides sufficient throughput for 128 kbps ISDN bearer channels and 1-2 Mbps ADSL rates. Place the MPC860SRCZQ5 between the DSL line driver (e.g., a codec) and the host processor; the CPM descriptor rings enable zero-CPU-overhead DMA. The 357-PBGA package supports the multi-layer PCBs typical of telecom CPE designs.

Industrial Ethernet Bridges and Gateways
With its integrated 10/100 Ethernet MAC and CPM serial controllers, the MPC860SRCZQ5 is well-suited to industrial Ethernet-to-serial gateways bridging fieldbus (Modbus, Profibus) to TCP/IP networks. The 50 MHz core handles TCP/IP stack and routing logic, while the SCCs manage the fieldbus serial interface. Deterministic CPM-driven DMA avoids jitter in industrial control loops. Place the MPC860SRCZQ5 at the heart of the gateway, paired with an Ethernet PHY (e.g., a 100BASE-TX transceiver) on the MAC side and an RS-485/232 transceiver on the SCC side. Industrial temperature variants (MPC860SRCVR50) extend operating range to -40C to +85C.
おすすめ
T1/E1 Multiplexers and Telecom Equipment
The MPC860SRCZQ5's dual SCCs and CPM architecture map directly to T1 (1.544 Mbps) and E1 (2.048 Mbps) multiplexer designs, where each SCC handles a full T1/E1 trunk. The 50 MHz PowerPC core runs signaling and management layers, while the CPM executes HDLC framing in hardware. The 357-PBGA supports the controlled-impedance trace routing required for E1/T1 line cards. Place the MPC860SRCZQ5 between the T1/E1 line interface unit (LIU) and the backplane; configure the CPM's time-division multiplexing for full trunk utilization. Rochester Electronics remains a primary source for long-lifecycle telecom deployments.
おすすめ
Legacy Avionics and Defense Controllers
The MPC860SRCZQ5's rugged 357-PBGA package, deterministic CPM-based I/O, and long-term availability through Rochester Electronics make it valuable in legacy avionics, naval communications, and military telemetry systems where redesign is prohibitively expensive. The 50 MHz PowerPC core provides reliable control processing for flight management, sensor aggregation, and MIL-STD-1553 bridging applications. Place the MPC860SRCZQ5 with conformal coating and thermal management suited to MIL-STD-810 environments. The architecture's deterministic interrupt latency is critical for avionics real-time response.
おすすめ
Point-of-Sale and ATM Networking
Legacy ATM and POS terminal designs leverage the MPC860SRCZQ5 for secure TCP/IP networking and peripheral management. The CPM's two SCCs handle encrypted line communications and peripheral serial ports (PIN pad, receipt printer, cash dispenser) simultaneously. The 50 MHz core runs the terminal application, transaction stack, and TCP/IP. The 357-PBGA package supports compact terminal form factors. Place the MPC860SRCZQ5 with hardware cryptographic accelerators offloading RSA/DES from the main CPU, and route sensitive signals through controlled-impedance differential pairs.
おすすめ
Set-Top Box and Cable Modem Headends
The MPC860SRCZQ5's integrated Ethernet MAC and CPM serial controllers suit legacy set-top box headend controllers and cable modem termination systems (CMTS). The 50 MHz core runs DOCSIS MAC layer scheduling and QoS, while the CPM manages downstream/upstream channel bonding. The 357-PBGA supports the high-density I/O required for multi-channel headend line cards. Place the MPC860SRCZQ5 upstream of the upstream/downstream RF modulator; configure CPM descriptors for bonded channel aggregation. Last-time-buy status makes Rochester Electronics the primary authorized channel.

設計ノート
The 357-PBGA package has a thermal resistance (theta_JA) of approximately 20-25 C/W depending on PCB layout. At 50 MHz with the CPM active, the MPC860SRCZQ5 dissipates under 1W typical, so a thermal pad with at least 4 thermal vias to an internal ground plane is sufficient for commercial-temperature operation. Industrial-grade variants (MPC860SRCVR50) in enclosed enclosures may require a heatsink or forced airflow to maintain junction temperature below +125C. Always validate thermal performance in the final system enclosure - do not rely on bare-die estimates.
Route all MPC860SRCZQ5 address, data, and control signals as 50 ohm controlled-impedance traces on the outer layers with continuous ground reference on the adjacent layer. Place decoupling capacitors (0.1 uF ceramic) within 5 mm of every power pin, plus bulk 10 uF tantalum or ceramic at the package corners. For the 357-PBGA escape routing, use microvia technology to fan out from the BGA grid; avoid stubs on high-speed signals. Maintain 3W spacing between clock and signal traces to minimize crosstalk.
Three common mistakes when designing with the MPC860SRCZQ5: (1) ignoring power sequencing - the MPC860 requires core voltage (typically 2.5V or 3.3V) before I/O voltage ramps; use a power supervisor to enforce sequencing. (2) Forgetting to configure the CPM interrupt controller - the CPM's separate interrupt vectors must be enabled in the SIU register before serial protocols will function. (3) Using incorrect JTAG chain configuration - the MPC860SRCZQ5 has both CPU and CPM TAP controllers; both must be in the scan chain for boundary-scan testing. Reference the MPC860 hardware specifications manual Section 13 (CPM) before firmware bring-up.
For BGA fanout, use a dog-bone pattern (trace + via) for the inner rows and direct via-in-pad for the outermost two rows. Place all power and ground balls on dedicated planes, not traces. The MPC860SRCZQ5 requires a minimum 6-layer PCB for clean signal integrity; 4-layer is acceptable for slower designs but compromises high-speed bus performance. Keep all differential pairs (Ethernet, T1/E1) matched within 5 mil tolerance.
