MC68MH360ZQ25VL Обзор
What is a QUICC processor? A QUICC is a one-chip integrated microprocessor plus peripheral combination that pairs a CPU32+ core with a dedicated communications processor module (CPM) to offload serial, networking, and protocol tasks from the main CPU. It is part of the broader ColdFire/M68K microprocessor hierarchy under the umbrella of 32-bit microprocessors (MPU) and embedded communications ICs, historically used in router line cards, WAN access multiplexers, and industrial serial concentrators.
Key features of the MC68MH360ZQ25VL include its 0.57 micrometer CMOS process technology, 25 MHz core clock, integrated 10 Mbps Ethernet MAC, DRAM controller, and 2 SMC + 1 SPI peripheral complement. The CPM contains its own RISC engine that handles the SCCs (Serial Communication Channels) and serial protocol DMA, which historically allowed the device to terminate HDLC, transparent, UART, and other telecom framing without burdening the CPU32+ core.
The architecture separates control-plane and data-plane processing: the CPU32+ executes the host operating system or control stack while the CPM handles time-critical serial bit processing in parallel. This dual-engine design gives the QUICC family deterministic throughput for multi-channel serial I/O, which is why these parts remain in service in long-lifecycle industrial and telecom equipment where deterministic serial behavior outweighs raw CPU clock speed.
Typical applications include router WAN interface cards, ISDN modem pools, telecom multiplexer line cards, industrial serial concentrators, SCADA remote terminal units, and legacy POS/ATM networking hubs. The integrated Ethernet MAC and DRAM controller let designers reduce board complexity, while the CPM removes the need for an external protocol-handling ASIC.
When designing with this MPU, ensure the 357-PBGA land pattern is faithfully reproduced and that the JTAG/BDM signals (BKPT, DSCLK, DSI, DSO) are accessible for in-circuit debug. Decouple VCC and VCCS supplies with low-ESR ceramic capacitors placed close to the package, and follow NXP errata for the M68360 family to avoid known CPM silicon issues.

Типичное применение
MC68MH360ZQ25VL подходит для 6 применениеs: Router WAN Interface Card, Telecom Multiplexer Line Card, Industrial Serial Concentrator, SCADA Remote Terminal Unit, Legacy POS / ATM Network Hub, ISDN Modem Pool Concentrator.
Router WAN Interface Card
The MC68MH360ZQ25VL is well suited to legacy router WAN interface cards because its integrated 10 Mbps Ethernet MAC plus 4 SCC (Serial Communication Channels) handle HDLC framing for T1/E1 leased lines without burdening the CPU32+ core. At 25 MHz the host CPU is fast enough to run a stripped-down routing stack while the CPM sustains deterministic serial bit timing in parallel, which is exactly the work load that originally brought QUICC into router line cards in the late 1990s. Placed on the WAN side of the backplane, the part eliminates an external protocol-handling ASIC and shrinks BOM cost. Engineers should still verify CPM silicon revision against the M68360 errata when qualifying for new deployments, but for maintenance of installed router bases the MC68MH360ZQ25VL remains a workhorse.
Рекомендуется
Telecom Multiplexer Line Card
In telecom multiplexer line cards, the MC68MH360ZQ25VL drives 2 SMC plus 1 SPI channels and four SCC channels through its CPM, terminating HDLC, UART, transparent, or bisync protocols across multiple T1/E1 drops in parallel. The integrated DRAM controller simplifies the line-card memory subsystem, and the 357-PBGA (25x25) footprint lets designers keep the same land pattern across product variants. Compared with a discrete CPU-plus-protocol-ASIC solution, the QUICC reduces part count and shortens firmware development time because the CPM RISC engine autonomously handles bit-level framing.
Рекомендуется
Industrial Serial Concentrator
For industrial serial concentrators collecting field telemetry from RS-232/422 devices, the MC68MH360ZQ25VL offers a deterministic CPM that can sustain full-duplex traffic on all four SCCs simultaneously without dropping characters. The 2 SMC ports can be configured for additional async UART channels, and the 1 SPI port can drive an external display controller or EEPROM array. With 25 MHz of CPU32+ headroom, the host core runs a real-time OS such as VxWorks or RTEMS and exposes the aggregated telemetry over the integrated 10 Mbps Ethernet MAC.
Рекомендуется
SCADA Remote Terminal Unit
SCADA remote terminal units rely on the MC68MH360ZQ25VL to terminate multiple serial SCADA protocols (DNP3, Modbus, IEC 60870) on its SCCs while the CPU32+ core runs the application logic. The integrated 10 Mbps Ethernet MAC provides the uplink back to the control center, and the DRAM controller supports the buffer memory required for protocol stack queues. Designers appreciate the deterministic CPM behavior for real-time polling of remote I/O at sub-100 ms intervals without jitter.
Рекомендуется
Legacy POS / ATM Network Hub
The MC68MH360ZQ25VL is found in legacy POS and ATM network hubs because its CPM can terminate multiple leased-line protocols at the back-office side while the host CPU handles transaction processing. The 357-PBGA footprint and the integrated 10 Mbps Ethernet MAC simplify the hub layout, and the 25 MHz core is fast enough to run the embedded transaction stack. For maintenance fleets that must keep these systems operational, the MC68MH360ZQ25VL and its drop-in 33 MHz sibling remain the primary spares.
Рекомендуется
ISDN Modem Pool Concentrator
In ISDN modem-pool equipment, the MC68MH360ZQ25VL acts as the central processor handling multiple PRI (Primary Rate Interface) channels via its SCCs, with the CPM offloading HDLC framing of the D-channel signaling. The integrated DRAM controller provides the buffer memory for B-channel data, and the integrated 10 Mbps Ethernet MAC uplinks the aggregate traffic. This is one of the classic QUICC design wins that drove the M68360 family adoption in late-1990s telecom infrastructure.

Заметки по проектированию
The 357-PBGA (25x25) footprint demands a 4-layer or 6-layer PCB with a continuous ground plane under the BGA and via-in-pad (VIP) plating for the inner-row signal balls. Estimated: routing 357 balls at 1.27 mm pitch on a 0.8 mm escape rule requires high-density interconnect (HDI) build-up, typically 1+1+1 microvia stackup. Without VIP, break-out of the inner rows becomes impossible on standard 4-mil trace geometry.
PBGA packages dissipate heat primarily through the die-to-lid path and the solder-ball grid. Estimated: at 25 MHz the CPU32+ core draws under 1 W, so the 357-PBGA runs comfortably at industrial ambient temperatures without a heatsink, but designers should still specify a copper coin or thermal via array under the central die flag to keep junction temperature below 100 C in enclosed sealed enclosures where ambient can climb above 70 C.
The 25 MHz CPU clock on the MC68MH360ZQ25VL is a CMOS-level signal that should be series-terminated at the driver with a 33 ohm resistor to damp reflections on long PCB traces to the SDRAM. Estimated: trace length above 50 mm requires 33 ohm series termination; traces below 25 mm typically do not need it. The CPM-derived serial clocks (SCC, SMC) are even slower and can usually be left unterminated, but the Ethernet MAC MII bus should be length-matched within 25 mm to avoid skew across the 25 MHz MII_TXCLK domain.
Two known pitfalls for the M68360 family are (1) leaving BKPT floating instead of pulling it high through 4.7 kilohm - this can cause unintended background-debug entry on power-up, and (2) using the on-chip DRAM controller without enabling the refresh timer in the System Integration Module configuration word. Both behaviors are called out in the M68360 errata and are easy to miss if you migrate firmware from a different M683xx device.
The MC68MH360ZQ25VL requires a 3.3 V core supply plus a 5 V tolerant I/O supply on a separate VCC/VCCS rail pair. Place a 0.1 microfarat X7R decoupling cap within 5 mm of every VCC ball and a 10 microfarat bulk tantalum near the package corner to absorb CPM DMA transients. Estimated: a fully-active CPM driving four SCCs draws an additional 150 mA peak on VCC during burst transfers, so the 3.3 V regulator must supply at least 600 mA continuous to stay in regulation.
Информация о соответствии
RoHS, lead-free and halogen-free declarations are not present in the verified web data for MC68MH360ZQ25VL. The M68360 family predates the original NXP RoHS transition program, so most early units are non-RoHS. Designers requiring RoHS compliance should request the official NXP material declaration directly through their distributor.
