MC68360RC25L Visão geral
An MPU (Microprocessor Unit) is the highest-level processing element in an embedded system, sitting above microcontrollers in the compute hierarchy because it integrates a full 32-bit CPU with external-memory bus and rich peripheral integration. The MC68360 family occupies the MPU tier of the Coldfire/M68K ecosystem: MPU -> 32-bit microprocessor -> integrated communications controller. The 'L' suffix indicates the lower 0C to 70C commercial temperature grade, distinguishing it from the 'C' military-grade variants.
Key features include the CPU32+ core (an enhancement of the original 68020 instruction set with table lookup and interrupt stacking), four independent SCCs that support HDLC, SDLC, Ethernet, UART, BISYNC, and transparent bit streams, and the SIM60 with chip-select logic, dual-port RAM, and DRAM controller. The device operates from a single 5.0 V supply and delivers sustained throughput on all four SCCs without external protocol assistance, with on-chip DMA channels that move data between peripherals and memory autonomously.
The architectural depth of the MC68360 comes from its tightly-coupled peripheral cluster: each SCC has its own physical interface, baud-rate generator, and receive/transmit FIFO, while a Time-Slot Assigner (TSA) time-division-multiplexes up to 32 logical channels on a single SCC, replicating TDM functions historically done with external logic. The result is a chip that can terminate multiple WAN trunks, an Ethernet port, or a multi-channel PCM highway with only the QUICC plus a small amount of PHY glue.
Typical applications include multi-port serial routers, ISDN terminal adapters, industrial serial concentrators, frame-relay access devices, and legacy telecom control cards. The four SCCs allow bridging between an HDLC WAN link, an Ethernet LAN port, and two async control channels using only one IC, which lowers system cost and board area relative to gluing separate UARTs to a discrete CPU.
When designing with the MC68360RC25L, remember that this part is part of the original Motorola/Freescale/NXP 68K lineage and is now in mature/legacy status. Plan for long-term supply with authorised distributors and consider the available same-package speed grades (RC25L, RC33L) when future-proofing the design.

Aplicações típicas
MC68360RC25L é adequado para 6 aplicaçãos: Multi-Port Serial Router, ISDN Terminal Adapter, Frame-Relay Access Device (FRAD), Industrial Serial Concentrator, Legacy Telecom Control Card, Embedded Protocol Bridge / Gateway.
Multi-Port Serial Router
The MC68360RC25L's four independent SCCs and on-chip DMA make it a natural fit for multi-port serial routers that bridge WAN links and LAN interfaces on a single IC. Each SCC supports HDLC, SDLC, PPP, and UART protocols with independent baud-rate generators, so the QUICC can terminate a frame-relay WAN port, an Ethernet-style LAN port, and two async control channels concurrently without external protocol silicon. The 25 MHz CPU32+ core handles routing table lookups and packet forwarding while the four SCCs push line-rate throughput. Power dissipation at 5 V / 25 MHz is modest enough for fan-less industrial enclosures, and the 241-pin PGA package supports a full 32-bit external memory bus for routing table storage. Compared with a discrete CPU plus four UARTs, the MC68360RC25L reduces PCB area by roughly 40 percent in legacy telecom router designs.
Recomendado
ISDN Terminal Adapter
ISDN terminal adapters require a CPU that can handle HDLC framing on the BRI U-interface plus V.120/V.110 rate adaptation on the synchronous serial side. The MC68360RC25L's SCCs natively support HDLC and transparent bit-stream protocols, allowing the QUICC to terminate the ISDN D-channel directly while a single SCC runs the B-channel aggregation. The SIM60 chip-select logic and DRAM controller interface directly to external 16-bit or 32-bit DRAM for buffer storage, eliminating the need for an external memory controller. The 5 V single-supply operation matches the power tree of typical ISDN BRI designs, and the 241-pin PGA footprint provides all necessary bus, interrupt, and peripheral pins in one package. For higher-throughput PRI designs the pin-compatible MC68360RC33L offers 33 MHz of CPU headroom in the same socket.
Recomendado
Frame-Relay Access Device (FRAD)
Frame-relay access devices aggregate multiple branch-office serial lines onto a single WAN trunk, and the MC68360RC25L's four SCCs map directly to this topology - three SCCs for branch-office links, one SCC for the uplink. Each SCC supports HDLC framing, DLCI de-multiplexing, and congestion feedback with hardware FIFO assistance, offloading the CPU32+ core from per-packet processing. The on-chip DMA moves frames between SCC FIFOs and external packet memory without CPU intervention, while the SIM60 controls a bank of external DRAM for frame buffers. Operating from a single 5 V rail, the QUICC simplifies FRAD power design compared with discrete CPU plus multi-UART solutions, and the 241-pin PGA package exposes the full 32-bit data bus needed for high-throughput frame forwarding in legacy telecom deployments.
Recomendado
Industrial Serial Concentrator
Industrial serial concentrators aggregate Modbus, Profibus, and proprietary RS-232/RS-422 links into a single Ethernet or higher-speed uplink, and the MC68360RC25L's four SCCs provide exactly the multi-protocol serial termination required. Each SCC can be independently programmed for UART, HDLC, or transparent modes, so a single QUICC chip replaces a stack of external UARTs while sharing the same interrupt, DMA, and memory architecture. The 0 C to 70 C commercial temperature range covers most indoor industrial enclosures, and the SIM60 chip-select logic can be configured to drive external non-volatile memory for configuration storage. For Ethernet-equipped concentrators the pin-compatible MC68EN360RC25L provides the MAC while preserving the 241-pin PGA layout. This makes the QUICC a long-life building block for factory-floor aggregation nodes.
Recomendado
Legacy Telecom Control Card
The MC68360RC25L is well suited to legacy telecom control cards that need to drive a TDM backplane, manage signalling links, and arbitrate multiple serial control channels. The QUICC's Time-Slot Assigner (TSA) time-division-multiplexes up to 32 logical channels on a single SCC, replicating TDM bus functions historically done with external logic and reducing BOM cost. The four SCCs run signalling channels (HDLC), bearer channels (transparent), and management ports (UART) concurrently under DMA control, while the CPU32+ core handles higher-layer control. The 241-pin PGA package provides the bus width and pin count needed for both the parallel system interface and the serial peripheral I/O. For higher-density line cards the pin-compatible 33 MHz RC33L provides 32 percent more CPU headroom in the same socket.
Recomendado
Embedded Protocol Bridge / Gateway
Embedded protocol bridges translate between fieldbus, serial, and Ethernet domains, and the MC68360RC25L integrates all the serial and DMA infrastructure needed to act as a hardware bridge without an external CPU. The four SCCs handle incoming fieldbus traffic while the on-chip DMA moves frames into a shared DRAM buffer, and the CPU32+ core performs protocol conversion in software at wire speed for typical fieldbus rates. The 5 V single-supply operation and 0-70 C commercial temperature range suit cabinet-mounted industrial gateways, while the 241-pin PGA supports the full 32-bit data bus plus all SCC, SMC, and I2C I/O. The Ethernet-equipped MC68EN360RC25L drops into the same socket when IP/Ethernet connectivity is required, making the QUICC family a long-life platform for industrial gateway designs.

- Single-chip multi-protocol integration (vs MC68360RC33K)
Notas de projeto
The MC68360RC25L operates from a single 5.0 V supply and draws on the order of several hundred mA at 25 MHz. Provide bulk decoupling (10 uF to 47 uF tantalum or polymer) close to the PGA power pins and high-frequency 0.1 uF ceramics across the supply. Estimate: with 5 V input and a 0.4 A typical core current, input power is approximately 2.0 W, so the 241-pin PGA thermal envelope is comfortable with passive airflow on a 4-layer board.
The 241-pin PGA package requires a through-hole PGA socket on the PCB; design the PCB footprint with the standard 47.24 mm x 47.24 mm land pattern and 0.100 inch pin pitch. Place external DRAM and ROM/Flash devices on the address/data bus in the inner board layers, and route the four SCC and two SMC signals to short, impedance-controlled tracks. The SIM60 chip-select outputs should be pulled up to 5 V through 10 kohm resistors if unused, to avoid spurious chip-select assertions during reset.
Do not confuse the 'L' (0 to 70 C commercial) and 'C' (military) temperature suffixes when sourcing; the 'K' suffix in MC68360RC33K denotes an extended temperature grade (-40 C to +85 C). The MC68360RC25L is NRND (Not Recommended for New Designs), so for new production NXP directs customers to the ColdFire MCF527x or PowerQUICC families, although the 68360 remains supported for legacy maintenance. Verify pin 1 orientation carefully when socketing the 241-pin PGA, since the dense pin grid makes visual inspection difficult.
Informações de conformidade
The MC68360 family is a legacy Motorola/Freescale/NXP M68K design. RoHS, REACH, and lead-free status are not explicitly stated in the verified web data; see _validation_note. AEC-Q100 is not applicable - this is an MPU, not an automotive-qualified part.
