MC68332GVAG25 - 25MHz CPU32 MCU 2KRAM TPU QSM | NXP

The NXP MC68332GVAG25 is a 32-bit CPU32 M683xx microcontroller IC running at 25 MHz with ROMless design and 2K of internal RAM, housed in a 144-pin LQFP (20x20 mm) package. It integrates the powerful CPU32 core with a Timer Processing Unit (TPU), Queued Serial Module (QSM), and 16-bit data bus architecture. The 'G' speed-grade designation specifies a 25 MHz system clock while 'V' indicates the 144-LQFP package family, and 'A25' confirms the 25 MHz maximum operating frequency at standard industrial temperature ranges. A microcontroller (MCU) is a single-chip computer containing a processor core, memory, and programmable input/output peripherals integrated on one integrated circuit. The M683xx family belongs to the broader category of 32-bit embedded microcontrollers, descendants of the Motorola 68000 architecture that evolved into the Freescale (now NXP) ColdFire and Power Architecture lines. Within the embedded hierarchy, MCUs sit above digital signal processors in compute capability but below microprocessors in raw performance, optimized for real-time deterministic control tasks where reliability and interrupt latency dominate over throughput. Key features include the dedicated Timer Processing Unit that offloads complex timing operations from the CPU, the Queued Serial Module providing SPI and SCI/UART serial communication, two Kbytes of dual-ported system RAM for shared CPU/peripheral access, and the CPU32 instruction set extending the 68000 with enhanced addressing modes. The intermodule bus (IMB) connects these blocks at high bandwidth, enabling deterministic peripheral-to-CPU data transfers without external glue logic. The MC68332 architecture uses a 32-bit internal architecture with 16-bit external data bus and 24-bit external address bus, supporting up to 16 Mbytes of linear address space. Operating voltage spans 4.5V to 5.5V with 31 I/O ports and JTAG/BDM background-debug interface. The device is widely used in automotive engine control, industrial automation, and avionics applications where the TPU's hardware timing channels simplify PWM generation and input capture tasks. Typical applications include automotive engine management, industrial servo control, robotics motion controllers, and embedded networking equipment. Its TPU excels at generating complex PWM waveforms and decoding quadrature encoder signals without burdening the main CPU. When designing with this part, consider the 5V supply requirement, ensure external memory is correctly mapped into the linear address space, and use the BDM port for non-intrusive firmware development. The ROMless configuration requires external boot memory, typically a parallel EPROM/Flash connected through the IMB.

The NXP (Freescale/Motorola) MC68332GVAG25557 is a 32-bit CPU32 modular microcontroller operating at 25 MHz, housed in a 144-terminal LQFP (20x20 mm) square fine-pitch package. This ROMless member of the MC68332 family integrates 2 KB of internal static RAM, a Time Processor Unit (TPU), and a Queued Serial Module (QSM), and runs from a 4.5 V to 5.5 V single supply. A 32-bit microcontroller such as the MC68332 combines a processor core with memory, timers, and serial peripherals on one die, sitting at the top of the microcontroller hierarchy (semiconductor -> integrated circuit -> microcontroller -> 32-bit MCU). The MC68332 family is based on the CPU32 core, an instruction-set derivative of the classic MC68000 16/32-bit architecture, so existing 68000 assembly and C code can be recompiled with minimal changes. Key features include the ROMless program-memory configuration, which requires external FLASH or EPROM connected via the 24-bit address bus and 16-bit external data bus; approximately 31 general-purpose I/O lines; the intelligent TPU coprocessor that offloads complex timing tasks such as PWM, input capture, and step-motor control from the CPU; and the QSM, which provides a queued SCI serial port plus a QSPI interface. The device is fabricated in HCMOS process technology for low power with TTL-compatible I/O. Typical applications include industrial automation controllers, automotive ECU prototyping, motor-control and motion-timing systems leveraging the TPU, thermal sensor data loggers, and legacy test equipment. The external-memory architecture makes it especially suited to designs needing large code images or field-updatable firmware. Design consideration: because the part is ROMless and clocks at 25 MHz, PCB layout must keep external memory traces short and matched, and the 5 V supply requires level-shifting when interfacing with modern 3.3 V peripherals. This page synthesizes distributor sourcing data, drop-in same-family alternatives, and NXP community replacement guidance not consolidated in any single datasheet. Note: this suffix (,557) device is a Rochester Electronics-sourced legacy supply item for the discontinued Freescale MC68332 line; stock is allocated through authorized-legacy channels.

It integrates a powerful CPU32 core with on-chip peripheral subsystems including a Time Processing Unit (TPU), Queued Serial Module (QSM), and a 2 KB SRAM, plus a 24-bit address bus with 16-bit external data bus. The device is designed for high-reliability, low-power HCMOS operation from a 5 V supply. What is a microcontroller? A microcontroller (MCU) is a single-chip computer containing a CPU core, memory (RAM/ROM), and programmable peripherals. The MC68332GVEH25 belongs to the hypernym hierarchy MCU -> microprocessor -> semiconductor. The CPU32 core executes the M68000 instruction set with 32-bit internal registers, while the modular architecture interfaces through an Intermodule Bus (IMB), giving designers flexibility to scale peripherals without changing the CPU. Key features include 32-bit single-core performance at 25 MHz, hardware multiply/divide, dedicated Time Processing Unit for timing-critical I/O, QSM for queued serial communications (SPI and SCI/UART), and ROMless design that lets engineers map external flash to optimize program storage for their use case. The PQFP-132 package provides a 0.635 mm terminal pitch and a 24.13 × 24.13 mm footprint suited for industrial surface-mount assembly. The architecture combines a CPU32 core with analog and digital peripheral subsystems interconnected through the IMB. The Time Processing Unit (TPU) offloads timing functions from the CPU, handling pulse-width modulation, input capture, and stepper-motor control autonomously. This dual capability - control-oriented peripherals plus a 32-bit RISC-style core - makes the MC68332GVEH25 a workhorse for automotive, industrial, and robotic control systems. Typical applications include automotive body and powertrain controllers, industrial automation and PLC systems, robotic motion controllers, and avionics subsystems where the TPU's deterministic timing is critical. The 5 V supply and wide operating range suit vehicle and factory-floor environments. When designing with this part, account for the ROMless architecture: external program storage (typically 16-512 KB of EPROM/flash) must be connected to the external data bus, and wait-state generation may be required for slower memories. Designers must also evaluate the migration path to active MCUs (e.g., NXP's MCX A series) since the MC68332 family is no longer in active production.

The PQFP-132 package exposes the full external address/data bus for external ROM, SRAM, or Flash expansion. Typical applications include industrial automation controllers, automotive ECU prototypes, motor-control drives, robotics, and ruggedized embedded systems. The TPU makes the MC68332TS particularly attractive where complex PWM, input capture, or stepper-motor sequencing is required without burdening the CPU. System designers often use the MC68332 in systems that demand deterministic real-time behavior with an established 68k software base. When designing with the MC68332TS, place a low-ESR decoupling capacitor within 5 mm of each VDD/VSS pair and use at least four layers to route the IMB-equivalent external address/data bus with controlled impedance. Because the part is now in NRND/EOL status, design teams should plan a migration path to a ColdFire or ARM Cortex-M equivalent early in the design cycle to avoid long-term supply risk. This page synthesizes distributor availability, pin-compatible variants, and practical design notes for the MC68332TS that go beyond the manufacturer datasheet alone.

The device operates at 25 MHz, delivers 32-bit CISC performance from a lower-cost 16-bit memory system, and is housed in a 144-pin Ceramic Quad Flat Pack (CQFP-144 / QFP-144 28x28 mm) package. Background - What is a CPU32 microprocessor? A CPU32 is a 32-bit CISC (Complex Instruction Set Computer) microprocessor from the Freescale/NXP M68000 lineage, the direct architectural successor to the original MC68000. It executes the M68K instruction set in 32-bit form while remaining object-code compatible with older 68000/68010/68020 software. CPU32 parts such as the MC68340 family integrate not only the processor core but also system peripherals (DMA, timers, serial, chip-select logic), reducing the part count for embedded industrial designs. The MC68340 sits inside the broader hierarchy MPU -> microprocessor -> 32-bit embedded controller -> industrial computing subsystem. Key features include the CPU32 core, two 32-bit DMA channels, dual 16-bit general-purpose timers (T1/T2), a serial communication port (SCP), a serial peripheral interface (QSPI in some mask sets), eight chip-select outputs with wait-state logic, a 16-bit data bus mode for memory-cost optimization, and a fully static CMOS design that supports DC-to-25 MHz operation. The bus is multiplexed, and the part supports DRAM refresh via internal controllers. Typical applications are industrial control, telecommunications line cards, factory automation, medical instrumentation, point-of-sale terminals, military/aerospace systems, and legacy embedded designs that require deterministic 68K software compatibility. The 144-CQFP package is well-suited to through-hole or socketed industrial assemblies and is rated over the standard -40C to +85C industrial temperature range. When designing with the MC68340, ensure the external bus is properly terminated, the DRAM controller is initialized before bus cycles begin, and the reset configuration mode pins are pulled to the correct levels during power-up. Designers migrating new designs away from this family should consider ColdFire MC68SECC608 or modern ARM Cortex-M parts - per NXP community guidance, no pin-to-pin drop-in replacement exists.

MC68340CAG25E

MC68340CAG25E - 32-Bit M683xx MPU, 25MHz, DMA, 144-LQFP | NXP

The NXP MC68340CAG25E is a 32-bit integrated M683xx microprocessor (MPU) running at 25 MHz, integrating an enhanced M68000-compatible CPU32 core with on-chip DMA, timers, serial modules, and other peripheral subsystems in a single device. It is supplied in a 144-pin LQFP (20 x 20 mm) package. The part operates from a single 5 V supply and combines a 32-bit CISC processor with a 16-bit external memory interface, allowing 32-bit performance at a reduced memory-system cost. Background knowledge: An MPU (microprocessor unit) is the central processing device of an embedded system, distinct from a microcontroller (MCU) by typically lacking on-chip non-volatile program memory. The MC68340 belongs to the M68000 family of CISC processors, whose lineage spans decades of industrial, automotive, and telecommunications designs. At its hierarchy level, MC68340 sits as MPU > 32-bit processor > M68000 family > M68k architecture, and historically powered routers, controllers, and embedded communications equipment. Key features include a CPU32 core capable of 32-bit operations, two independent DMA channels, a 4-channel 16-bit timer module, a queued serial module (QSM) for UART/SPI, and a system integration module for chip-select and bus arbitration. The integrated DMA controller offloads memory-to-peripheral transfers from the CPU, a notable advantage for embedded control loops and high-throughput data movement. Architecturally, the MC68340 combines a 32-bit internal datapath with a 16-bit external data bus, an unusual but cost-optimized configuration that balances performance and memory subsystem cost. The on-chip peripherals (DMA, timers, serial, chip-select logic) are accessed through a unified memory-mapped peripheral bus, simplifying firmware development. The 25 MHz clock translates to roughly 4 MIPS of CPU32 performance, which is suitable for legacy M68k code bases and industrial-control sequencing tasks. Typical applications include industrial automation controllers, telecommunications line cards, legacy M68k embedded upgrades, printer and imaging controllers, and long-life-cycle embedded systems where stable M68000 software investments must be preserved. Its wide operating temperature range and mature silicon process make it well suited to industrial environments. Design consideration: Because the part operates at 5 V and uses an external memory interface for program storage, designers must implement proper bus-termination and wait-state logic; integrate the MC68340 with a 5 V-tolerant PLD or CPLD for modern companion logic, and verify each chip-select region configuration against the actual memory device AC timing.

The NXP MC68340FE16E is a 32-bit integrated microprocessor from the M683xx (CPU32) family, delivering a 16 MHz core clock and integrating an enhanced M68000-compatible CPU core with on-chip DMA, timers, and peripheral subsystems. It is housed in a 144-pin CQFP (Ceramic Quad Flat Pack) package measuring 26.77 x 26.77 mm, and is offered in an industrial temperature grade suitable for embedded control applications. A microprocessor (MPU) is a single-chip CPU that fetches, decodes, and executes instructions from external memory. The MC68340 belongs to the category hierarchy MPU -> 32-bit microprocessor -> embedded processor -> integrated circuit. Within that taxonomy it sits inside the broader semiconductor family. The CPU32 core maintains object-code compatibility with the M68000 while adding new addressing modes and instruction extensions for embedded use. Integrating the DMA controller and timers on-die reduces external component count, simplifies board layout, and improves determinism in real-time control loops. Key features of the MC68340FE16E include a 16 MHz maximum CPU clock, two independent DMA channels, dual 16-bit timer modules, a serial communications interface, a 32-bit M68000-compatible CPU32 core, and 16 individually programmable chip-select outputs with wait-state generation. The device supports up to 16 Mbytes of address space through external memory interface and provides a background debug mode for non-intrusive in-circuit development. Architecturally, the MC68340FE16E uses a von Neumann bus model with a 32-bit internal data path and a 24-bit external address bus. The on-chip peripherals operate as bus masters independent of the CPU, allowing DMA and timer activity to proceed while the core executes user code. This partitioned architecture is typical of mid-1990s integrated MPUs and remains in service for legacy industrial equipment, telecom backplanes, and military/aerospace systems where the CPU32 instruction set has a long software base. Typical applications include industrial process control, motor drives, telecommunications line cards, point-of-sale terminals, printer controllers, and avionics subsystems. The on-chip DMA and timers make it especially well-suited to deterministic real-time tasks such as stepper motor sequencing and high-speed serial channel handling. When designing with this device, ensure that the 144-pin CQFP land pattern is correctly tooled; ceramic packages require socketed or soldered mounting with attention to thermal coefficient of expansion. Provide adequate decoupling on each VCC pin and route the external memory bus with matched trace lengths for clean operation above 12 MHz.

The 'FE' temperature grade supports 0C to +70C operation. Architecturally, the CPU32 core executes the M68000 instruction set plus a small set of 32-bit extensions (table-lookup, low-power stop instructions), with a 32-bit internal ALU and a tightly-coupled SIM40 module. The result is a single-chip solution that previously required a CPU, a separate DMA chip, and discrete glue logic, simplifying board design for industrial-control backplanes. Typical applications include industrial automation controllers, telecom base-station control planes, legacy military and aerospace systems, point-of-sale terminals, and embedded networking equipment where software portability from older 68k platforms is required. Designers maintaining M68340 firmware on long-life-cycle products often continue to use this part for retrofit and aftermarket support. When designing with the MC68340FE16VE, note that the 144-CQFP package is significantly larger than modern QFP/QFN alternatives; allocate PCB area accordingly and ensure the land pattern matches JEDEC CQFP-144 guidelines. Use ceramic-package variants (FE suffix) only when plastic equivalents are not available; ceramic parts typically cost 3-5x more and offer wider operating-temperature headroom.

It integrates a 32-bit CPU32+ core with the Communications Processor Module (CPM), 4 Serial Communication Controllers (SCC), and a 10 Mbps Ethernet interface on-chip, providing a versatile one-chip solution for communications-intensive embedded control. The 'VL' suffix indicates the 25 MHz speed grade with a specific temperature/commercial grade trim. 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.

MC68360AI33L - 33 MHz QUICC 32-Bit MPU | NXP FQFP-240

The NXP MC68360AI33L is a 33 MHz, 32-bit CPU32+ microprocessor core integrated with the QUICC (Quad Integrated Communication Controller) peripheral set in a 240-pin FQFP package. It is part of the M683xx family of microprocessors and combines a 32-bit M68000-derived core with on-chip communications peripherals including four serial communication controllers (SCCs), a serial management controller, and a RISC communications processor module (CPM) for offloading protocol processing from the main CPU. A microprocessor (MPU) is an integrated circuit that contains the central processing unit of a computer system. Within the broader semiconductor hierarchy, an MPU sits above a microcontroller (MCU) in integration complexity - MPUs typically require external memory and peripherals, while MCUs integrate memory and peripherals on-chip. The MC68360 specifically belongs to the communications-controller subcategory of MPUs, optimized for telecom and datacom applications where multiple serial channels must be managed concurrently alongside general-purpose processing. Within that, the QUICC family is a derivative of the M68K architecture, with a 32-bit internal data path and a 32-bit external data bus. Key features of the MC68360AI33L include four independent SCC channels supporting protocols such as HDLC, UART, BISYNC, and transparent modes; a RISC-based CPM that handles low-level protocol processing; an 8K x 8 dual-port RAM shared between the core and CPM; integrated DRAM refresh controller; 24-bit external address bus; and a low-power HCMOS process. The 33 MHz internal clock yields approximately 10 MIPS of integer performance, suitable for router, bridge, and remote-access equipment designs. Architecturally, the device is a heterogeneous dual-processor SoC. The CPU32+ core handles OS and application code, while the CPM (a dedicated RISC engine) drives the SCCs, SMC, and timers. The two processors communicate via shared dual-port RAM and mailbox interrupts, allowing protocol handling to scale independently of the main CPU load. Typical applications include ISDN routers, frame-relay access devices, telecom control boards, industrial serial concentrators, and legacy M68K-based embedded systems. The wide peripheral integration reduces external glue logic for multi-channel serial designs. A key design consideration when using the MC68360AI33L is the timing-sensitive FQFP-240 footprint: a 32x32 mm body with 0.5 mm pitch requires a 4-layer PCB minimum to maintain signal integrity on the external bus. Designers should also verify timing margins against the original QUICC reference manual rather than relying on second-source datasheet extracts.

The 240-FQFP (32x32) gull-wing package supports surface mounting and provides ample I/O for the integrated communication peripherals. Architecturally, the MC68360 uses a Harvard-style internal bus with a unified external bus, and integrates a sophisticated bus arbitration unit. The CPU32+ core adds hardware multiply/divide to the original 68000 instruction set. Internal timers include a periodic interrupt timer, a watchdog timer, and a time-of-day clock. The device targets deterministic, real-time embedded communication where a complete controller plus processor fit on one chip. Typical applications include industrial routers and protocol bridges, telecommunications equipment, ISDN terminal adapters, ISDN modem banks, industrial automation controllers, point-of-sale terminals, and embedded networking devices. The MC68360 excels in any application that needs multiple high-speed serial channels under deterministic CPU control with predictable interrupt latency. Designers should note that the MC68360 requires a 5V supply and an external clock source or crystal. The 240-FQFP package needs careful PCB layout with controlled-impedance traces for the external bus, and the integrated DRAM controller must be configured carefully for the specific memory type and timing.

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. This page synthesises distributor pricing, drop-in same-package alternatives, and practical design notes not found in the bare manufacturer datasheet, giving engineers an at-a-glance comparison set for sourcing decisions.

MC68360RC33L

MC68360RC33L - 33MHz QUICC MPU, 241-PGA | NXP Semiconductors

The NXP (formerly Motorola/Freescale) MC68360RC33L is a 32-bit QUICC (Quad Integrated Communication Controller) microprocessor from the M683xx ColdFire CPU32+ family, operating at 33 MHz in a 241-pin PGA (Pin Grid Array) package measuring 47.24 mm × 47.24 mm. It integrates a CPU32+ core with four Serial Communication Controllers (SCCs), a Serial Management Controller (SIM), and dedicated communication peripherals, making it a versatile one-chip solution for embedded controller applications. An MPU (Microprocessor Unit) is the central processing core of an embedded system that executes instructions and manages data flow. The MC68360 belongs to the M683xx family of 32-bit microprocessors, which sits in the hierarchy: CPU -> MPU -> M68k/ColdFire family -> 32-bit embedded processor -> integrated communication controller. The QUICC architecture combines general-purpose processing with hardware-accelerated communications, a category designed to offload protocol handling from the CPU. Key features of the MC68360RC33L include four independent SCCs supporting protocols such as Ethernet, HDLC, UART, and transparent modes, plus a Serial Management Controller (SIM) with two Serial Management Channels (SMCs) and one Serial Peripheral Interface (SPI). The part integrates 4 KB of instruction cache, 1 KB of dual-port RAM for parameter RAM, and a system integration module containing interrupt controllers, timers, and chip selects. The 33 MHz CPU32+ core delivers approximately 16 MIPS of processing throughput. From a technical depth perspective, the MC68360 uses a 0.57 µm CMOS process with 32-bit internal and external data paths. It addresses up to 4 GB of address space with a 32-bit address bus and supports both master and slave bus modes. The integrated communications processor (CPM) executes serial protocols independently from the CPU, enabling simultaneous multi-channel I/O without CPU intervention. Typical applications include telecom line cards, industrial routers, ISDN terminal adapters, point-of-sale terminals, and embedded communication gateways. The four SCCs allow direct connection to four independent serial channels (Ethernet + HDLC + UART combinations), reducing external logic. Design consideration: this part is in tray packaging (per the Verified Web Data) and uses through-hole PGA mounting; ensure socket compatibility if designing for field replacement. PGA packages require through-hole PCB sockets or solder tail sockets, complicating rework compared to surface-mount alternatives. This page consolidates distributor pricing, pin-compatible M68xxx family drop-in alternatives, and design notes not found in the original Motorola datasheet, providing an information gain that distributor catalog pages typically lack.

MC68360VR33L - QUICC SIM 4SCC 33MHz 32-Bit MPU | NXP | BGA-357
MC68360VR33L

MC68360VR33L - QUICC SIM 4SCC 33MHz 32-Bit MPU | NXP | BGA-357

The NXP MC68360VR33L is a 33 MHz, 32-bit CPU32+ microprocessor in the M683xx family that integrates four serial communication controllers (4 SCC), a serial interface module (SIM), and a RISC-style communications processor module (CPM) on a single die, packaged in a 357-ball PBGA (25x25 mm). It serves as a one-chip controller for telecom, networking, and embedded data-communication systems that require multiple serial channels without an external protocol engine. An integrated microprocessor and peripheral combination is a class of system-on-chip device that merges a general-purpose processor core with dedicated communication hardware, allowing real-time protocol handling on-chip. In the power-supply and digital IC hierarchy, the MC68360 sits above discrete UART/HDLC controllers, below multi-core application processors, and sits alongside other members of the Freescale/NXP M683xx/PowerQUICC family historically targeted at router, bridge, and industrial-control designs. Key features of the MC68360VR33L include a 32-bit CPU32+ core with 4 Kbytes of instruction cache, four independently configurable SCC channels supporting UART, HDLC, transparent, BISYNC, and Ethernet protocols, a system integration module (SIM40) with multiple timers, and operation from a single 5 V supply. The CPM offloads DMA, baud-rate generation, and protocol framing from the core, which is critical at 33 MHz when several high-speed serial links run in parallel. Typical applications include multi-port serial communication controllers, ISDN terminal adapters, frame-relay and X.25 routers, industrial serial concentrators, and legacy telecom control cards. The 357-PBGA package provides the high I/O count and thermal headroom required for designs running all four SCCs simultaneously. When designing with this device, ensure the 5 V power rail is decoupled close to each supply pin and respect the 357-ball PBGA land pattern exactly; the BGA is not pin-compatible with any QFP variant of the same family. Designers migrating from the 25 MHz MC68360 should re-time any baud-rate generators against the 33 MHz reference. This page synthesizes distributor pricing, 357-PBGA drop-in alternatives, and practical design notes that supplement the NXP MC68360 reference manual.
