MPC860ENZQ50D4R 개요
A PowerQUICC microprocessor is a category of integrated communications processor that combines a general-purpose PowerPC CPU and a separate RISC-based communications engine (CPM) on a single die. Within the broader taxonomy it is a microprocessor -> embedded MPU -> communications processor -> networking SoC. PowerQUICC parts dominated telecom equipment in the 1990s and early 2000s as one-chip routers, bridges, and remote-access concentrators. They remain in service today in long-lifecycle industrial and telecom installations where redesign risk outweighs BOM savings.
Key features of the MPC860ENZQ50D4R include the embedded 32-bit PowerPC core at 50 MHz, integrated CPM for HDLC/PPP/SCC/UART protocol offload, four 8-bit parallel ports, a 32-bit address/data bus interface to external memory, SDRAM controller, and a small but functional on-chip instruction/data cache. The device supports external bus arbitration for multi-master designs and exposes dedicated timers, a watchdog, and JTAG boundary-scan. Power supply is typically 3.3 V I/O with a core voltage generated internally from the same rail on this mask-set.
Architecturally, the MPC860ENZQ50D4R uses a Harvard-style cache, a unified TLB/MMU, and an internal system bus that decouples the core from the CPM, allowing sustained serial DMA without CPU intervention. The 50 MHz rating refers to the CPU clock; the bus clock and CPM clock are derived and typically run at 25 MHz on this speed grade. Power dissipation scales linearly with the active serial channels and memory traffic, so idle/standby current is a more representative number for low-duty-cycle applications.
Typical applications include low-end routers, CSU/DSUs, ISDN terminal adapters, industrial serial-to-Ethernet gateways, and remote telemetry units where the CPM offloads HDLC framing from the host CPU. The wide range of on-chip serial channels and the legacy Freescale/NXP toolchain ecosystem make it a frequent choice for sustaining or replicating designs built around the PowerQUICC architecture.
When designing with this part, verify the exact voltage rail of your specific MPC860EN mask (the EN suffix on this part indicates the integrated Ethernet SCC variant), and provide proper bus-termination and decoupling per the PowerQUICC hardware specifications manual. Long-term availability must be checked - PowerQUICC I parts are reaching end-of-life per the NXP PCN, so designers should plan second-source or migration strategies up front.

일반적인 애플리케이션
MPC860ENZQ50D4R 적합 용도: 6 애플리케이션s: Low-End Router / Bridge, CSU/DSU and T1/E1 Termination, ISDN Terminal Adapter / NT1, Industrial Serial-to-Ethernet Gateway, Remote Telemetry / SCADA RTU, Legacy Telecom Line Card / Channel Bank.
Low-End Router / Bridge
The MPC860ENZQ50D4R is a strong fit for low-end router and bridge designs because its 50 MHz PowerPC core combined with the on-chip Communications Processor Module (CPM) can sustain HDLC, PPP, and UART framing on multiple serial channels without loading the host CPU. The integrated Ethernet SCC on the EN mask eliminates the need for an external MAC, reducing BOM cost. A typical design pairs this part with 16 to 32 MB of SDRAM and 4 to 8 MB of flash, with the CPM handling WAN-side framing while the CPU runs the routing stack. At 50 MHz the device comfortably handles sub-10 Mbps aggregate throughput per direction, which is appropriate for legacy branch-office routers, SOHO gateways, and protocol-converter bridges still common in industrial networks. Compared with newer QorIQ P1 devices, the PowerQUICC I has lower raw compute but higher per-watt efficiency for sustained serial-channel workloads.
추천
CSU/DSU and T1/E1 Termination
The MPC860ENZQ50D4R is well-suited for CSU/DSU and T1/E1 line-termination units because its CPM provides dedicated TDM channels and serial controllers capable of running HDLC framing at T1 (1.544 Mbps) and E1 (2.048 Mbps) line rates. The 50 MHz core is fast enough to manage Layer-2 protocol conversion and minimal SNMP management traffic without an external host CPU. Designs typically use one SCC for the WAN-side T1/E1 transceiver (e.g., a Dallas/Maxim DS2155 or equivalent) and another SCC or SMC for the DTE interface. The integrated Ethernet SCC enables a single-chip IP-over-PDH gateway. The 357-PBGA package has the thermal headroom for fanless industrial enclosures at typical T1/E1 line-card power budgets.
추천
ISDN Terminal Adapter / NT1
For ISDN terminal adapters and NT1 network terminations, the MPC860ENZQ50D4R provides the necessary HDLC hardware offload and timing-stamping features via its CPM. The 50 MHz core is sufficient to handle BRI (2B+D) and PRI (30B+D) signalling alongside PPP, MLP, or V.120 encapsulation. Designs pair this part with an ISDN transceiver (such as the Motorola/Agilent HC5517 or Siemens PSB 3186) and rely on the EN Ethernet mask for LAN-side connectivity on router-integrated NT1 designs. The legacy toolchain support and broad third-party driver base make this part attractive for sustaining existing ISDN product lines, especially in regions where ISDN remains in service.
추천
Industrial Serial-to-Ethernet Gateway
The MPC860ENZQ50D4R is a common building block for industrial serial-to-Ethernet gateways, where its CPM handles multiple RS-232/RS-485 serial channels while the Ethernet SCC terminates the LAN side. With four SCCs and two SMCs available, a single chip can convert up to six independent serial ports to TCP/IP, Modbus/TCP, or proprietary industrial protocols. The 50 MHz core is adequate for protocol-conversion overhead at sub-Mbps aggregate rates, and the industrial operating temperature grade makes it suitable for factory-floor deployment. The part's longevity in the field has created a stable supply of reference designs, drivers, and example code, which reduces time-to-market for new gateway SKUs.
추천
Remote Telemetry / SCADA RTU
For remote telemetry units (RTUs) and SCADA outstations, the MPC860ENZQ50D4R's combination of serial-channel density, Ethernet SCC, and watchdog timer enables a single-chip solution. The CPM supports HDLC, asynchronous, and bisync serial protocols commonly used in SCADA masters, while the Ethernet SCC provides IP-based backhaul. The 50 MHz core handles local logic, data concentration, and DNP3 / IEC 60870-5 protocol stacks at the modest data rates typical of utility telemetry. The 357-PBGA package and 3.3 V supply simplify integration into solar-powered or battery-backed enclosures. Designs in this space frequently migrate from this part to PowerQUICC II for higher channel counts, but the MPC860ENZQ50D4R remains viable for sub-16-channel RTUs.
추천
Legacy Telecom Line Card / Channel Bank
Within legacy telecom line cards and channel banks, the MPC860ENZQ50D4R provides TDM aggregation and per-channel processing for voice and data services. The CPM's TDM interface allows direct connection to a backplane TDM bus (e.g., H.110 or similar), and the 50 MHz core handles signalling, echo-cancellation control, and per-channel management. The integrated Ethernet SCC supports VoIP gateway cards in hybrid TDM/IP systems. The part's continued availability via authorized aftermarket distributors makes it viable for sustaining installed equipment where redesign would trigger carrier recertification.

설계 노트
The MPC860ENZQ50D4R runs from a 3.3 V I/O rail and generates its core voltage internally on the EN mask. Per the PowerQUICC hardware specifications, provide at least 4 x 0.1 uF decoupling capacitors placed close to each of the four PBGA quadrant supply pins, plus bulk decoupling of 22 to 47 uF tantalum or polymer on the main supply. Power sequencing is not required since the on-chip regulator handles core voltage ramp independently of I/O. Estimated: at 50 MHz with two active SCCs, supply current is approximately 250 to 300 mA; verify with the full PowerQUICC hardware specifications manual before sizing input fuses.
The 357-PBGA 25x25 mm package requires a 4-layer or 6-layer PCB with continuous power and ground planes under the IC to provide both decoupling and thermal dissipation. Per the Freescale/NXP layout guidelines, escape routing should fan out on the top layer with via-in-pad or dog-bone fanout on inner layers; keep all high-speed bus and serial traces to matched-length rules (within 150 mils on the 32-bit external bus, within 50 mils on Ethernet differential pairs). The PBGA thermal pad must be soldered to a flooded ground plane for the rated thermal resistance.
The MPC860ENZQ50D4R's external memory bus and Ethernet MII/ RMII signals require source-series termination (22 to 33 ohm) on clock and strobe lines to control ringing on the 25 MHz bus clock and 25/50 MHz Ethernet clocks. Per the hardware specifications manual, drive strength should be configured to its lowest setting that still meets the AC timing requirements; over-driving the bus causes SSO-induced jitter that will fail compliance on Ethernet RMII links. Estimated: at full bus loading the maximum operating frequency is derated; derate to 40 MHz when driving four SDRAM loads.
A common mistake is selecting the wrong mask (EN vs DT vs EH) without verifying Ethernet requirements - the EN mask integrates a single Ethernet SCC, while DT integrates dual Ethernet. Another pitfall is omitting the proper reset circuit; the MPC860ENZQ50D4R requires a minimum reset pulse of 8 us and the HRESET line must remain low until the 32 kHz reference is stable. Finally, do not assume the part is RoHS-compliant without checking the specific date code - earlier lots were Pb-bearing.
