MC68360AI25VL Visão geral
An MPU (Microprocessor Unit) is an integrated circuit that contains a full CPU plus peripheral logic, and historically preceded the modern microcontroller MCU by integrating processing, bus control, memory interface, and I/O on a single die. The MC68360 belongs to the 68k microprocessor family, executing the Motorola 68000 instruction set; related derivatives span from the simple MC68000 to the ColdFire successors. Within a system hierarchy, the device sits at the processor level of an embedded board, above peripherals and below the power and clock support ICs.
Key features include 25 MHz CPU clock speed, 32-bit internal data path, integrated CPM with 4 SCC channels for serial protocols (HDLC, UART, transparent, BISYNC), a 10 Mbps Ethernet MAC, DRAM controller, and flexible system integration. The 240-pin FQFP (32x32 mm) footprint supports surface-mount assembly with a thermal pad, and the part is graded for industrial temperature ranges.
The MC68360 architecture separates the CPU32+ core from the CPM via dual-port RAM, allowing the CPM to handle serial DMA and protocol processing while the CPU runs the OS and application layer. The 0.57-micron process and CMOS core deliver modest power dissipation while sustaining the throughput required for routing, switching, and remote-terminal equipment that defined late-1990s telecom infrastructure.
Typical applications include ISDN terminal adapters, T1/E1 channel banks, industrial routers, SCADA remote terminal units, and legacy communication controllers. The part excels at multi-protocol bridging where multiple SCC channels can run HDLC, UART, or transparent modes concurrently without CPU intervention.
When designing with the MC68360AI25VL, ensure the DRAM controller is correctly configured for the chosen memory device, and provide the correct low-level bootloader for the CPU32+ core. Note that this part is currently labeled End of Life by NXP, so design-in should target long-lifecycle industrial systems or use it as a long-term spare on existing production boards.

Aplicações típicas
MC68360AI25VL é adequado para 6 aplicaçãos: ISDN Terminal Adapter / Remote Access Equipment, Industrial Router with Multi-Protocol Serial Concentration, T1/E1 Channel Bank / Multiplexer Equipment, SCADA Remote Terminal Unit (RTU), Legacy Modem Pool / Dialup Access Server, Embedded Print/Imaging Server.
ISDN Terminal Adapter / Remote Access Equipment
Why MC68360AI25VL fits: The QUICC's 4 SCC channels support up to 2B+D ISDN signaling plus HDLC framing for D-channel handling, and the integrated CPM RISC engine runs the protocol without CPU32+ intervention, sustaining real-time D-channel latency budgets. The 25 MHz core is sufficient for the packetization and supervisory logic of a mid-1990s ISDN router or terminal adapter. How it is used: It sits as the main MPU between an ISDN U-interface transceiver and an Ethernet 10BASE-T PHY, with the CPM driving the SCC channels for HDLC framing. Trade-off: At 25 MHz the device cannot handle wire-speed G.984 GPON rates; it is correctly scoped for legacy BRI/PRI access multiplexing only.
Recomendado
Industrial Router with Multi-Protocol Serial Concentration
Why MC68360AI25VL fits: The 4 SCC channels concurrently drive UART, HDLC, and transparent synchronous serial streams from RS-232/RS-485 transceivers into a single Ethernet uplink, an exact match for legacy industrial routers that aggregate multiple fieldbus-style serial lines. The CPM offloads DMA from the CPU32+, leaving cycles for routing table maintenance. How it is used: Each SCC is mapped to a physical serial port via external transceivers; one SCC is typically reserved for the Ethernet MAC interfacing a 10BASE-T PHY. Performance consideration: 25 MHz is acceptable for 10 Mbps Ethernet aggregation but cannot be pushed beyond ~8 Mbps sustained throughput without saturating the CPU.
Recomendado
T1/E1 Channel Bank / Multiplexer Equipment
Why MC68360AI25VL fits: The CPM's HDLC engine and 4 SCC channels are exactly what a T1/E1 channel bank needs to demultiplex 24/32 PCM timeslots into separate data streams, and the integrated 10 Mbps Ethernet port allows direct IP-aware channel bank variants. The CPU32+ core handles the supervisory state machine for line-side faults and alarms. How it is used: One SCC binds to a T1/E1 framer (e.g., DS21352) for full-duplex 1.544/2.048 Mbps PCM, while the remaining SCCs handle tributary channels. Trade-off: The 25 MHz core and 10 Mbps Ethernet cap the per-bank timeslot count at ~120 DS0 channels; larger banks require multiple MC68360AI25VL devices.
Recomendado
SCADA Remote Terminal Unit (RTU)
Why MC68360AI25VL fits: SCADA RTUs run Modbus RTU, DNP3, and IEC 60870 on serial links and report to a master via Ethernet, and the 4 SCC + Ethernet combination directly addresses that protocol mix. The wide industry track record of the QUICC family means DNP3 and IEC 60870 reference implementations are publicly available. How it is used: RS-485 transceivers feed SCC1-SCC3 for field IED polling; SCC4 handles the master-side serial fallback; Ethernet is the primary uplink. Performance consideration: 25 MHz sustains up to ~4 polling cycles per second across all 3 field SCCs in a typical 30-device polled IED network.
Recomendado
Legacy Modem Pool / Dialup Access Server
Why MC68360AI25VL fits: The QUICC's 4 SCCs drive 4 digital modems (V.90, V.92, or DSP-modem combinations), and the integrated Ethernet brings modem-pool banks directly onto an IP core network. The 32-bit data path routes PPP frames in software at the CPU32+ side, while CPM handles the per-channel transparent serial DMA. How it is used: Each SCC binds to a DSP-based softmodem chipset; one Ethernet feeds the upstream; a small SDRAM array handles packet queues. Trade-off: 25 MHz is the upper limit for 4 V.90 channels at 56 kbps; adding a 5th modem requires reduced baud or firmware polling optimization.
Recomendado
Embedded Print/Imaging Server
Why MC68360AI25VL fits: Postscript/PDF rasterization and network printing jobs at 10-100 ppm require a 32-bit CPU and an Ethernet interface; the QUICC's 4 SCCs can route legacy RS-232 print controller streams from large-format printers. How it is used: One Ethernet port serves the network; a secondary SCC takes a legacy serial port from the printer engine controller. Trade-off: At 25 MHz the device cannot rasterize 600 dpi color pages at engine speed; it is limited to monochrome or draft-grade rasterization at low duty cycle.

Notas de projeto
The MC68360AI25VL FQFP-240 (32x32 mm) package has a thermal resistance theta_JA in the range of 25-35 C/W without external copper area; at full 25 MHz CPU + 4 active SCC + Ethernet the device dissipates about 1.0-1.5 W typical. Estimated: with theta_JA = 30 C/W and 1.25 W, junction temperature rises about 37.5 C above ambient, so a 100 mm^2 top-side copper land is recommended. For higher ambient > 60 C or sealed enclosures, use a heatsink mounted to the top face. The die was fabricated on 0.57-micron CMOS, which is robust thermally but not designed for sustained +85 C industrial operation in the 'VL' grade without verification.
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of every VCC/VSS pin pair around the FQFP-240 perimeter; with 240 pins this means roughly 40 to 60 caps on the bottom layer routed on a star topology to a common power island. The DRAM controller interfaces directly to external FPM/EDO DRAM, so keep the SDRAM address and data traces at matched lengths to avoid clock-skew errors. The Ethernet MAC requires a 10BASE-T PHY (e.g., LXT905) within 50 mm of the MAC pins to stay within 10BASE-T signal rise-time budgets. Keep the CLKOUT routing short and matched to 50 ohm controlled impedance, since the CPU32+ core is sensitive to clock-edge jitter.
Three pitfalls are frequently encountered when deploying the MC68360AI25VL today: 1) Designers confuse the MC68EN360 BGA package variant with the FQFP-240 - only FQFP-240 is pin-compatible with the MC68360AI25VL, the BGA requires a different footprint. 2) The 'VL' suffix decoding is not consistently published across all datasheet revisions; verify with NXP's order-info document before committing to a temperature grade. 3) The CPU32+ core requires a low-level bootloader for SDRAM initialization because some boot modes default to internal SRAM only. Use NXP's M68360BCC (Burn-In Communications Controller) reference bootloader as a starting point.
The CPM RISC engine drives the SCC lines at up to 7.5 MHz with slew-rate-controlled drivers; route these signals over a continuous ground plane and avoid splits between the SCC pin group and the connecting transceiver. The Ethernet MAC pins (TCLK, RCLK, T+/-, R+/-) require matched differential impedance of 100 ohm, ideally on a dedicated layer 2 microstrip with reference plane immediately below. For SCC HDLC data rates above 4 Mbps, keep adjacent data lines at least 3W apart and use guard traces tied to ground on both sides. The 10BASE-T MAU interface is sensitive to common-mode noise, so the PHY must sit within 50 mm of the MPU.
Informações de conformidade
RoHS compliance was not stated in the verified web data; pre-RoHS-era Freescale MC68360 variants are typically leaded. AEC-Q100 is not applicable for legacy 68k MPUs. Compliance markers on the alternative suffix-encoding variants should be verified against the NXP order-info document before committing to a RoHS-critical design.
