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.

MC68360AI33L557 - 33MHz QUICC 32-Bit MPU | NXP Semiconductors

The NXP (formerly Freescale) MC68360AI33L557 is a 32-bit M683xx family microprocessor that integrates a CPU32+ core running at 33 MHz with on-chip peripheral controllers, housed in a 240-pin FQFP package (32x32 mm). It belongs to the QUICC (Quad Integrated Communication Controller) family and is specified for industrial temperature grade operation. A microprocessor (MPU) is an integrated circuit that contains the arithmetic logic unit, control unit, register file, and memory interface of a computer on a single die. The MC68360 specifically embeds a CPU32+ core (32-bit internal, with 32-bit data and address buses) alongside four serial communication controllers, a system integration module, and a parallel interface. In the broader taxonomy, this part sits as: microprocessor -> processor -> integrated circuit -> semiconductor. It is the successor concept to the older MC68302 with substantially enhanced communication throughput. Key features include a 33 MHz maximum operating frequency, 32-bit address and data buses, an integrated memory controller supporting DRAM, SRAM, and ROM, four independent SCC (Serial Communication Controller) channels with HDLC/SDLC/UART support, an SPI port, an I2C controller, and a 32-bit parallel interface for external peripherals. 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. Industrial-grade silicon guarantees operation from -40C to +85C, suitable for telecom and factory environments. This page consolidates distributor pricing, lifecycle pin documentation, and drop-in alternatives that go beyond what is found on the original Freescale/NXP product page, with cross-references focused on the M683xx family footprint.

The NXP MC68360CAI25L is a 25 MHz CPU32+ microprocessor from the M683xx family that integrates a 32-bit processor core with the QUICC (Quad Integrated Communication Controller) peripheral set, packaged in a 240-pin FQFP (32x32). The 'C' suffix denotes the commercial 0C to 70C temperature range, while 'A' indicates the standard (non-ECC) memory configuration and 'I' marks the industrial-grade plastic FQFP package. A QUICC (Quad Integrated Communication Controller) is a category of communications-centric microprocessor that combines a CPU core with multiple serial communication controllers (SCCs), serial management controllers (SMCs), a system integration module (SIM), and a time-slot assigner on a single die. Positioned in the broader system hierarchy as MPU -> microprocessor -> integrated MPU/MCU -> semiconductor device, the QUICC family sits between simple microcontrollers and high-end networking processors, optimized for WAN, LAN, and telecom bridge/router designs. Key features include a 32-bit CPU32+ core with 4 GB address space, 25 MHz system clock, four serial communication controllers (SCCs) supporting HDLC/SDLC, UART, transparent, and Ethernet (10 Mbps) protocols, two serial management controllers (SMCs), a 4-channel DMA controller, and a system integration module containing chip-select logic, interrupt controller, and bus arbitration. According to the manufacturer datasheet, the part operates from a 3.0V to 3.6V supply. Architecturally the MC68360CAI25L pairs the proven 68000-derived CPU32+ core (which executes the M68000 instruction set with additional instructions for improved compiler efficiency) with the dedicated communications engine, enabling simultaneous protocol processing on all four SCCs without CPU intervention. The 0.57 micron CMOS process and 240-pin FQFP package were standard for high-pin-count embedded processors of the late 1990s. Typical applications include ISDN terminal adapters, multi-port serial bridges, industrial routers and protocol converters, frame-relay access devices, low-end WAN access multiplexers, and legacy telecom control boards. The device's ability to run four SCC channels concurrently makes it well suited for aggregating T1/E1 or V.35 links into a single processor. When designing with this part, plan for the 240-pin FQFP land pattern, allocate sufficient PCB area for the 32x32 mm footprint, and ensure proper power-supply decoupling on each Vdd/Vss pin pair. Note that NXP has issued an End-of-Life notice for this part per the product page; long-term designs should evaluate NXP ColdFire successors or cross-reference drop-in equivalents. This page synthesizes distributor pricing, drop-in alternatives, application guidance, and design notes not found in the manufacturer datasheet alone - useful for both sustaining-engineering (legacy board repair) and obsolescence-migration planning.

MC68360RC25L

MC68360RC25L - QUICC 25MHz CPU32+ MPU, 241-PGA | NXP

The NXP MC68360RC25L is a 25 MHz CPU32+ microprocessor integrated into the QUad Integrated Communication Controller (QUICC) family, packaged in a 241-pin PGA (Ceramic Pin Grid Array, 47.24 mm x 47.24 mm). The device combines a 32-bit CPU32+ core with the communications-oriented peripheral set that defines the QUICC line: a System Integration Module (SIM), four Serial Communication Channels (SCCs), a Serial Management Channel (SMC), and an Inter-Integrated Circuit (I2C) controller, plus a parallel interface and DMA. This integration makes the MC68360RC25L especially suited for embedded networking and telecom control designs where a single chip must manage both protocol processing and host-side control. 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. 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.

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.

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.

Its headline parameters are 25 MHz core clock, 32-bit ColdFire CPU32+ core, and a 357-ball plastic BGA package, with four serial communication controllers (SCC), a serial interface module (SIM), and the QUICC engine for protocol offload. What is a QUICC microcontroller? A QUICC (Quad Integrated Communication Controller) is a category of integrated microprocessor + peripheral combination IC that pairs a CPU core with multiple communication protocol engines, allowing the chip to handle serial protocol framing (HDLC, UART, BISYNC, transparent, Ethernet) without burdening the CPU. The MC68360 sits in the broader hierarchy of MPU > 32-bit microprocessor > ColdFire/CPU32+ family > communication controller IC > semiconductor. QUICC devices are a defining category of Freescale/NXP legacy telecom silicon and remain in use in long-lifecycle industrial equipment, telecom backplanes, and protocol-bridging designs. Key features of the MC68360ZQ25VL include four serial communication controllers, an SPI/I2C-compatible serial interface, a 32-bit CPU32+ core at 25 MHz, eight 16-bit timers, and a flexible system integration unit with chip selects and interrupt controllers. The QUICC CPM coprocessor offloads serial processing, leaving the CPU free for control-plane tasks, while the on-chip memory map supports DRAM, SRAM, and ROM external memories with wait-state configuration. Architecturally, the part combines a 32-bit CPU32+ core (M68000-family ISA) with a separate RISC-based communications processor module (CPM) that contains the SCCs, SMCs, and a serial DMA controller. The two-processor internal structure allows deterministic serial throughput independent of CPU load, a key reason this family persists in protocol-bridging telecom designs. Typical applications include industrial telecom controllers, legacy WAN routers, serial-protocol bridges (HDLC/async), industrial automation backplanes, POS and ATM/frame-relay edge nodes, and any long-lifecycle system originally designed around the QUICC platform. The wide integration of peripherals reduces board area and BOM versus discrete processor+comm-controller designs. When designing with this part, note that it is pinned out as a 357-ball PBGA requiring careful PCB stack-up and controlled-impedance routing for the parallel memory bus, and that several variants in the MC68360 family share the same package but differ in frequency, RAM configuration, or Ethernet presence. Designers should verify the exact suffix (ZQ25VL, VR25VL, CAI25L) against the system clock and peripheral requirements before reusing an existing layout.

The Motorola MC6840CP is a Programmable Timer Module (PTM) for the M6800 processor family, providing three independent 16-bit binary counters with corresponding control registers and a status register. The verified source data identifies a programmable subsystem component designed to generate variable system time intervals, but it does not specify the target package dimensions, pin count, supply voltage, clock frequency, or operating-temperature grade. A programmable timer module is a peripheral category that generates timed events, measures intervals, counts external events, and coordinates periodic interrupts in a processor-based system. In the M6800 ecosystem, the MC6840 extends the processor with hardware timing functions that would otherwise require software loops, external counters, or additional logic. Its three counters make it useful for several independent timing tasks within one component. The three 16-bit binary counters are the central architectural feature identified by the Motorola datasheet result. Each counter corresponds to a control register, allowing firmware to select operating behavior, while the status register supports observation of timer events. Specific counter modes, clock inputs, interrupt outputs, read/write timing, and maximum operating frequency require confirmation from the manufacturer datasheet because those details are absent from the supplied verified snippets. Typical legacy applications include periodic service routines, elapsed-time measurement, pulse generation, event counting, industrial-control timing, and M6800-family test equipment. In each case, firmware configures the relevant counter, polls or receives a timer indication, and uses the resulting event for control flow or measurement. The hardware timer reduces processor workload, but software must still initialize each control register and interpret status correctly. The key design consideration is verification of interface details. Before schematic capture or PCB layout, engineers should obtain the original manufacturer datasheet and confirm the exact CP package, pin assignments, signal names, voltage ratings, timing limits, and environmental specifications. Search results include an MC6840CP-G listing from Rochester Electronics, but the suffix and source do not establish that MC6840CP and MC6840CP-G are electrically, mechanically, and pin-for-pin interchangeable. This page combines the verified Programmable Timer Module description, three-counter architecture, distributor evidence, and sourcing links with explicit uncertainty markers. It distinguishes verified facts from missing electrical, package, pinout, pricing-tier, and lifecycle data rather than inferring specifications that are not present in the supplied sources.

The NXP MC68711E20CFNE2 is an 8-bit HC11-series microcontroller with 2 MHz CPU clock, 20 KB of on-chip One-Time-Programmable (OTP) EPROM, and 768 bytes of RAM, housed in a 52-pin PLCC (Plastic Leaded Chip Carrier) package measuring 19.1 x 19.1 mm. The MC68711E20CFNE2 suffix "E20" identifies a 20 KB OTP EPROM memory size, "CFN" denotes the 52-pin PLCC industrial-temperature package, and "E2" indicates the OTP (erasable window-less) memory option versus the E3/E4 UV-erasable versions. What is a microcontroller (MCU)? A microcontroller is a single-chip computer that integrates a CPU, memory (program + data), and peripheral interfaces on one piece of silicon. The HC11 (High-performance Complementary Metal-Oxide Semiconductor 68HC11) family belongs to the CISC (Complex Instruction Set Computer) microcontroller hierarchy: MCU -> 8-bit MCU -> HC11 family -> M68HC11 E-series -> industrial/automotive embedded controllers. CISC MCUs offer rich instruction sets, multiple addressing modes, and bit-manipulation features favored in legacy automotive, industrial-control, and instrumentation designs. Key features include an M68HC11 CPU core with 16-bit internal addressing, an 8-channel 8-bit ADC, asynchronous serial communications interface (SCI), serial peripheral interface (SPI), 16-bit timer/counter, pulse accumulator, real-time interrupt, computer-operating-properly (COP) watchdog, and up to 38 general-purpose I/O lines. The OTP EPROM allows one-time factory or field programming using an EPROM programmer socket, while the 768-byte on-chip RAM supports variable data storage for stack, registers, and scratchpad operations. The MC68711E20CFNE2 uses a fully static CMOS design allowing clock frequencies down to DC, with low-voltage (3 V) variants available within the E-series family. The 52-pin PLCC package supports both surface-mount assembly and programming-socket insertion for development and prototyping. Operating temperature spans the industrial range of -40 °C to +85 °C, making it suitable for automotive under-hood, factory automation, and harsh-environment embedded applications. Typical applications include automotive engine control units (ECUs), antilock braking systems (ABS), industrial process controllers, instrumentation, security-system controllers, and legacy embedded-control replacements where pin-compatible HC11 footprint compatibility is required. Designers choose the MC68711E20CFNE2 when a mature, well-documented 8-bit core with on-chip EPROM and rich peripherals is preferable to migrating code to a newer architecture. When designing with this device, ensure the OTP programming algorithm matches the manufacturer's specification - incorrect Vpp ramp timing or address sequence can permanently damage the part. Allow at least 100 ms power-on-reset settling time, and use the COP watchdog to detect firmware lockup conditions in safety-critical applications.

MC68711E20MFNE2

MC68711E20MFNE2 - 8-Bit HC11 MCU 20KB OTP 768B RAM | NXP

The NXP MC68711E20MFNE2 is a member of the M68HC11E family of 8-bit microcontrollers featuring a 4 MHz M68HC11 CPU core, 20 KB of one-time programmable (OTP) EPROM program memory, 768 bytes of on-chip RAM, and 38 digital I/O lines. It is housed in a 52-pin PLCC (J-Lead) package measuring 19.1 mm x 19.1 mm and is supplied in tube packaging for through-hole-style surface mounting. The 68HC11 family is a classic M68HC11 architecture microcontroller family. An 8-bit MCU (microcontroller unit) integrates a CPU, program memory (ROM/EPROM/OTP), data RAM, and on-chip peripherals onto a single silicon die. Within the broader embedded taxonomy, 8-bit MCUs sit below 16-bit and 32-bit MCUs in computational throughput, but offer deterministic behavior, low cost, and easy programmability that make them ideal for cost-sensitive, latency-predictable control applications ranging from appliances and HVAC to industrial automation and automotive subsystems. The HC11 was one of the most widely adopted 8-bit cores of the 1990s and remains in long-lifecycle products and legacy maintenance designs. Key features of the MC68711E20MFNE2 include its 4 MHz maximum bus frequency, integrated oscillator support, the M68HC11 instruction set with extensive addressing modes, and on-chip peripheral functions such as timers, an 8-bit ADC (analog-to-digital converter), and serial interfaces (SCI/SPI). The 20 KB OTP memory supports customer-programmable code development for low-to-medium volume production, while the 768-byte RAM provides data working space suitable for small control loops and stack operations. The 52-PLCC package provides robust J-lead contacts for robust socketing and field replacement. Architecturally, the E-series variants share the same CPU, instruction set, and peripheral set, differing primarily in memory type and size. The 'E20' suffix designates 20 KB of EPROM/OTP, while 'MFN' indicates the plastic-leaded chip carrier package and the E2 temperature/operating variant. This part uses CMOS technology with a fully static design that allows operation over a wide voltage range and clock-speed-down to DC. Typical applications include industrial control systems, automotive body and chassis electronics, HVAC controls, security systems, and consumer appliances where the proven HC11 ecosystem and existing codebase provide a low-risk migration path. The OTP memory variant specifically suits medium-volume production where mask-ROM tooling costs are not justified. When designing with this part, designers must consider that it is flagged as 'No Longer Manufactured' by the manufacturer, so lifecycle planning should include secure long-term inventory or migration to the actively-produced M68HC11 mask-ROM or EEPROM siblings, or to a modern ColdFire/S08 successor.

MC68882EI25AR

MC68882EI25AR - 25MHz 68882 FPU Co-Processor | 68-PLCC

The NXP MC68882EI25AR is a 25 MHz floating-point unit (FPU) co-processor in the Motorola M68000 family, packaged in a 68-pin PLCC (Plastic Leaded Chip Carrier) measuring 24.21 x 24.21 mm. It functions as a dedicated math co-processor that pairs with an M68000-series CPU (e.g., MC68020, MC68030, MC68040) to offload IEEE 754 single- and double-precision floating-point arithmetic, dramatically accelerating numerical workloads versus software emulation on the host CPU. The part is specified for a 5 V nominal supply (4.75 V to 5.25 V operating range) and a commercial 0C to +70C temperature grade. An FPU co-processor is a specialized processor that works in lockstep with a host CPU to execute floating-point instructions in hardware rather than emulating them in software. Within the M68000 ecosystem hierarchy, the MC68882 sits beside the host CPU as an M-class co-processor (companion chip), falling under the broader categories of math co-processor -> co-processor -> specialized IC -> microprocessor peripheral. By handling transcendental functions (sine, cosine, log, exp), IEEE 754 arithmetic, and packed BCD, the 68882 delivered workstation-class numeric performance to 68k-based systems such as the Amiga, Atari, early Macintosh, and various industrial/embedded controllers. Key features include hardware IEEE 754 single and double precision, eight 80-bit floating-point registers organized as a stack with renaming, fully concurrent execution with the host CPU through the M68000 coprocessor interface, and support for the complete M68000 family F-line instruction set including FMOV, FADD, FMUL, FDIV, FSIN, FCOS, FLOG and FEXP. The 25 MHz suffix (-25) corresponds to a 25 MHz system-clock operation. The PLCC-68 surface-mount package retains the traditional J-lead footprint for easy socket replacement on legacy boards. The 68882 architecture consists of an instruction-decoder/prefetch unit, an FPU execution datapath, an 80-bit register file, and a bus interface that communicates with the host CPU through the M68000 coprocessor protocol. Unlike modern integrated FPUs, the 68882 occupies a separate socket and is invisible to software once configured - the host CPU decodes F-line opcodes and dispatches them to the co-processor transparently. Internal pipeline overlap allows the host and FPU to run concurrently, hiding latency. Typical applications include legacy M68020/M68030 workstation upgrades (Amiga 3000/4000, Atari TT/Falcon, early Mac II/Quadra via PDS cards), industrial-control retrofit boards requiring floating-point acceleration, vintage computer restoration projects, and educational/emulation environments studying 68k architecture. Because the part is now in the obsolete/EOL category, it is most often sourced for maintenance of installed bases rather than new design. A key design consideration when working with this part is that the 68882 must be clocked at the same frequency as, or in lockstep with, the host M68000 CPU; mismatch causes timing violations on the coprocessor handshake. Because the part is obsolete, second-source and franchised stocking distributors are the primary supply channel. Designers should always verify lot traceability and request a manufacturer certificate of conformance when procuring.

MC68882RC33A - 33MHz 68040 FPU Co-Processor 68-PGA | NXP

The NXP MC68882RC33A is a 33 MHz floating-point unit (FPU) co-processor for the Motorola 68020 and 68030 M68K family of microprocessors, housed in a 68-pin Pin Grid Array (PGA) package measuring 26.92 x 26.92 mm. It is designed as a strict drop-in companion to the host CPU, providing hardware-accelerated IEEE 754 single, double, and extended-precision floating-point arithmetic that the integer host processor would otherwise have to emulate in software. A floating-point co-processor is a specialized arithmetic processor that operates in parallel with the main CPU. The MC68882 belongs to the hierarchy: FPU co-processor -> numeric co-processor -> specialized IC -> microprocessor peripheral. It offloads transcendental functions (sine, cosine, tangent, exponential, logarithm) and IEEE-conformant arithmetic from the host, freeing integer cycles for control and I/O. Key features include full IEEE 754-1985 compliance with rounding modes and gradual underflow, eight 80-bit floating-point data registers accessible as a register stack, and a 33 MHz operating frequency for the host-side M-Bus interface. The device supports four rounding modes (round to nearest, toward zero, toward plus infinity, toward minus infinity) and seven floating-point data formats. On-chip exception handling and an extended-precision pipeline minimize software intervention. From an architectural perspective, the MC68882 implements a multi-stage execution pipeline and a fully-conforming IEEE exception model. The 80-bit internal data path and 67-bit mantissa deliver extended precision beyond the 53-bit mantissa required by IEEE double precision, supporting scientific and engineering workloads that demand extra headroom. Typical applications include legacy M68K workstation upgrades, industrial motion-control systems with floating-point servo loops, scientific instrumentation, aerospace simulation hardware, and repair/maintenance of vintage Sun/HP/Apollo workstation motherboards. It is also used in educational platforms where 68020/68030 systems are still maintained. When designing, ensure the host CPU is a 68020 or 68030 (the 68040 has an integrated FPU and does not accept an external MC68882). Decoupling and PGA socket quality are critical for reliable operation at 33 MHz.

It integrates an enhanced M68HC08 CPU08 core, LINbus/SCI/SPI connectivity, on-chip PWM, low-voltage detect (LVD), power-on reset (POR), and runs at up to 8 MHz internal bus frequency, all targeted at low-cost, high-performance general-purpose consumer and industrial applications. An 8-bit microcontroller is a single-chip computer built around an 8-bit data path, integrating CPU, RAM, non-volatile program memory (Flash or ROM), and a curated set of on-chip peripherals (timers, communication controllers, ADC, GPIO). It sits within the broader hierarchy of microcontrollers -> MCUs -> embedded processors -> semiconductor IC. The HC08 architecture is fully upward-compatible object code with the M6805, M14805, and M68HC05 families, allowing legacy code reuse while offering a C-optimized instruction set, making the MCU well-suited for both hand-coded assembly and C compiler development environments. Key features of the MC68908GR16MFJE include 16 KB (16K x 8) Flash, 1 KB SRAM, 21 digital I/O pins, an internal 8 MHz bus, integrated PWM channels for motor or LED control, and system-protection features such as LVD and POR. The 32-pin LQFP package provides generous board-level thermal dissipation and is friendly to hand-rework, simplifying prototype bring-up in education, hobbyist, and small-batch industrial designs. Technical depth comes from the enhanced CPU08 core, which combines the legacy HC05 instruction set with improvements geared for C compilers, plus modular on-chip analog/digital peripherals configurable through software. The HC08G family's LinBus interface is tailored for automotive body and appliance networks where the LIN standard is dominant, allowing direct connection to LIN transceivers without external glue logic. Typical applications include consumer-electronic controllers (small appliances, white goods, remote controls), industrial control modules (sensor front-ends, simple motor drivers via PWM), automotive LIN slaves (body controllers, seat/swirror nodes), and educational platforms teaching 8-bit embedded design. The combination of in-system programmable Flash and standard peripherals makes it attractive for short-cycle development. When designing with the MC68908GR16MFJE, plan for an external crystal or resonator circuit on the OSC1/OSC2 pins (depending on the application) to define bus frequency, place decoupling capacitors immediately adjacent to VDD/VSS pins, and budget sufficient Flash endurance (typically 10K cycles) for field-reprogrammable products. Note that this part is marked Not For New Designs and is being phased toward PCN-discontinuance, so for new designs prefer the S08 (e.g., MC9S08) or Kinetis (Cortex-M0+) successors.

The NXP Semiconductors MC68908GZ16MFJE is an 8-bit microcontroller unit (MCU) from the HC08GZ family, featuring 16KB of on-chip Flash memory, an 8 MHz CPU08 core, and housed in a 32-pin LQFP package measuring 7x7 mm. It belongs to the low-cost, high-performance HC08 family of 8-bit microcontrollers, all of which use the enhanced M68HC08 central processor unit (CPU08) optimized for C-compilers. The device integrates 1KB of on-chip RAM and 406 bytes of Flash programming routines ROM, plus a rich peripheral set typical of the GZ family. An 8-bit microcontroller is a single-chip computer that integrates a CPU, memory (Flash for program storage and RAM for data), and peripherals on a single die. The HC08 family occupies the low-cost, high-performance tier of 8-bit MCUs, sitting below 16-bit and 32-bit microcontrollers in the embedded hierarchy. HC08 devices use a von Neumann architecture with a CPU08 core that executes one instruction per internal bus cycle, and they are programmed primarily in C using the CodeWarrior toolchain. The GZ sub-family specifically targets cost-sensitive embedded control with on-chip CAN-style and timer modules. Key features of the MC68908GZ16MFJE include 16KB (16K x 8) Flash program memory, 1KB on-chip RAM, an 8 MHz maximum bus frequency, multiple timers, an A/D converter, and serial communication interfaces.

MC68908GZ16VFJE - 8-Bit 8MHz 16KB MCU | NXP | Industrial

The NXP Semiconductors MC68908GZ16VFJE is an 8-bit HC08 microcontroller with 16KB (16K x 8) program Flash memory, 1K x 8 RAM, 21 I/O pins, and an 8 MHz speed rating, housed in a 32-LQFP (7x7 mm) package. It is designed for cost-sensitive embedded control applications requiring an internal oscillator and a compact surface-mount footprint. What is an 8-bit microcontroller? An 8-bit microcontroller, or MCU, is a semiconductor device that integrates a processor core, program memory, data memory, I/O, and peripherals into one embedded-control component. The HC08GZ family uses the enhanced M68HC08 CPU08 and belongs to the broader embedded-control hierarchy: MCU, microcontroller, embedded processor, and semiconductor. Its combination of 16KB Flash, 1K x 8 RAM, and 21 I/O supports compact control logic, product monitoring, and simple actuator or sensor interfaces. Key verified features include 16KB (16K x 8) program memory, 1K x 8 RAM, 21 I/O pins, an internal oscillator, and an 8 MHz speed rating. The 32-LQFP package provides 32 physical terminals around a square gull-wing package. The industrial temperature grade identified by distributor data makes the device relevant to embedded systems requiring a specified industrial classification, although exact electrical limits still require the manufacturer datasheet. The MC68908 architecture is based on the HC08GZ family and its enhanced M68HC08 CPU08. Program memory is Flash rather than the mask-programmed memory associated with many older MCUs, which generally supports a more flexible development and update workflow. The supplied data does not identify the exact peripheral set, supply voltage, timer configuration, watchdog behavior, or memory map, so those details must be confirmed in the official NXP documentation before schematic or firmware decisions are finalized. Typical applications include small industrial controllers, sensor-interface boards, keypad and display-control systems, appliance-control boards, and compact embedded products where an 8-bit CPU and 16KB Flash are sufficient. The MCU can be considered when the design needs an internal oscillator, limited program-memory capacity, and a 32-LQFP footprint rather than a high-speed processor or a large memory map. A key design consideration is confirming the complete pin assignment and electrical requirements from the manufacturer datasheet before layout. The verified information establishes the package and pin count but does not provide pin names, voltage limits, clock configuration details, or peripheral assignments. Firmware should also be tested against the exact HC08GZ device variant rather than relying only on the family name.

MC68908GZ8MFAE - 8-Bit HC08 MCU, 8KB Flash, 48-LQFP | NXP

The NXP (formerly Freescale) MC68908GZ8MFAE is an 8-bit microcontroller from the HC08GZ family, featuring an enhanced M68HC08 central processor unit (CPU08), 8 KB of on-chip Flash program memory, and a 48-pin LQFP (7x7 mm) package. It operates at a bus frequency up to 8 MHz and is specified over the standard 3.0 V to 5.5 V supply range typical of HC08-family industrial microcontrollers. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data memory, and a set of on-chip peripherals (timers, ADC, communication interfaces, GPIO) into one device. In the broader taxonomy, the MC68908GZ8MFAE sits as: microcontroller -> 8-bit MCU -> HC08 family -> HC08GZ sub-family -> CISC core -> embedded system building block. This hierarchy matters for engineers selecting replacements or migrating code between HC08 variants, because the instruction set, peripheral set, and memory map vary by sub-family even though the core is identical. Key features include 8 KB Flash with in-application programmability, an 8-channel 10-bit ADC, up to 37 GPIO lines depending on package, multiple timers (including a 4-channel 16-bit timer with PWM), an SCI (serial communications interface) and an SPI peripheral, plus a system integration module supporting up to 33 interrupt sources. The 48-LQFP-7x7 footprint is the industry-standard surface-mount package for the HC08GZ family and provides a thermal resistance suitable for industrial operating environments. Architecturally, the CPU08 core is a CISC design with 16-bit stack operations, an X-index register, a H:C stack pointer, and direct page addressing that simplifies C-to-HC08 code generation. The device integrates a low-voltage detect (LVD) module, a computer operating properly (COP) watchdog, and a clock generator module supporting either a 1 MHz to 8 MHz external crystal or an internal reference oscillator - useful in cost-sensitive industrial control boards. Typical applications include industrial motor control sub-systems, white-goods and appliance controllers (washing machines, dishwashers, HVAC blower controls), point-of-sale terminals, low-end automotive body controllers, and general-purpose 8-bit replacement designs where legacy HC08 code must be preserved. Its wide 3 V to 5.5 V supply tolerance makes it a practical fit for both battery-backed and 5 V industrial rails. When designing with this MCU, verify the package code suffix (MFAE = 48-LQFP) matches the PCB footprint before laying out - the HC08GZ family is also offered in 32-LQFP, 44-LQFP, and 64-LQFP variants with different pinouts. Decouple VDD/VSS with 100 nF plus 4.7 uF bulk caps placed within 5 mm of the pins, and route the oscillator traces with guard rings because the HC08's PLL and bus clock are sensitive to switching-noise injection.

This cost-effective HC08 CISC MCU is designed for embedded control applications requiring reliable Flash-based program storage and a rich peripheral set. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and peripheral subsystems into one device. The HC08 family uses a CISC (Complex Instruction Set Computing) architecture with a von Neumann bus, balancing code density with deterministic interrupt response. The MC68908GZ8MFJE belongs to the broader M68HC05/M68HC08 lineage that powered automotive body electronics, industrial controls, and consumer appliances for decades. Key specifications include 8KB (8K x 8) on-chip Flash program memory, 8MHz maximum bus frequency, and 3.3V/5V dual-voltage operation that simplifies interfacing to both 3.3V logic and legacy 5V peripherals. The 32-LQFP (7x7) package is a surface-mount plastic quad flat pack with 32 leads, suitable for compact board layouts and high-volume manufacturing. Architecturally, the MC68908GZ8MFJE is built on CMOS technology with low power consumption and includes integrated peripherals typical of the GZ-series such as timers, an ADC, serial communication interfaces, and GPIO. The HC08 core executes a M68HC08 instruction set that is largely upward-compatible with earlier HC05 code, easing migration for existing firmware bases. Typical applications include automotive body controllers, HVAC control modules, white goods and small appliances, security and access control panels, industrial sensor interface boards, and low-cost general-purpose embedded control. The wide 3.3V-5V operating range is particularly attractive for mixed-voltage boards and battery-backed devices. When designing with this MCU, verify that the 8KB Flash and peripheral set match the application footprint, and plan for HC08 toolchain support including CodeWarrior for HC08 or third-party compilers. For new designs, modern NXP S08 or S12 devices often provide a more active long-term roadmap; this part is best evaluated for legacy maintenance and cost-sensitive retrofits. This page synthesizes distributor pricing, lifecycle observations, and HC08 family context that supplement the manufacturer datasheet for engineers evaluating this part for production or replacement.

MC68A02CL Clocked Microprocessor | Rochester Electronics

Rochester Electronics, LLC MC68A02CL is a microprocessor IC based on the MC68A02 family and supplied with a clock and optional RAM. The verified distributor and Rochester Electronics listings identify the device as a processor and peripheral component, but the supplied web data does not publish a complete electrical specification table. Consequently, processor speed, address-space size, bus timing, supply voltage, and environmental ratings should be confirmed in the original manufacturer documentation before schematic capture or production release. A microprocessor is the central execution element of an embedded computer system. It fetches instructions, decodes operations, updates registers and memory, and coordinates peripheral devices through address and data buses. The MC68A02 belongs to the Motorola 68A02 microprocessor lineage, an early 8-bit embedded-processing architecture historically used in industrial controllers, communications equipment, and custom systems. Its integrated clock and optional RAM distinguish this CL-coded configuration from related package or option variants. The principal verified feature set is concise: the MC68A02CL includes a clock, supports optional RAM, and is categorized by Rochester Electronics as a processor and peripheral device. Distributor records classify it as a microprocessor IC, while Rochester describes it more specifically as an MC68A02 microprocessor with clock and optional RAM. The CL ordering code therefore identifies the exact configuration, but it should not be treated as a complete electrical substitute specification without the original data sheet. Legacy 68A02 systems require careful architecture-specific verification. Bus timing, memory mapping, interrupt behavior, peripheral interfacing, and clock assumptions are determined by the original processor documentation and the surrounding board design. Because the provided search records do not include the complete pinout, clock frequency, address width, data-bus width, or voltage limits, engineers should preserve the original MC68A02CL footprint and consult archived Motorola documentation before selecting another device. Typical applications include industrial automation controllers, embedded communications equipment, legacy test systems, and repair or sustainment of equipment built around the Motorola 6800-family architecture. For new designs, a currently supported microcontroller may offer better tooling, integration, and availability. For existing products, however, maintaining the documented MC68A02CL configuration can reduce PCB, firmware, and validation risk when the original system is already field deployed. The primary design concern is data authenticity because the available records expose commercial information but not a complete manufacturer data sheet. Confirm the package, pin assignments, clock requirement, bus interface, memory architecture, supply rails, and timing margins against an archival source before layout changes or substitutions. Do not infer these values from the MC68A02 family name alone. This page combines verified distributor availability, quoted pricing, product classification, and practical legacy-component guidance with the Rochester Electronics source record. It also distinguishes confirmed facts from missing technical parameters, helping engineers assess procurement risk while avoiding unsupported claims about clock rate, pinout, memory capacity, or electrical limits.

MC68CK16Z1CAG16 - 16-Bit HC16 16MHz ROMless MCU | NXP

The NXP MC68CK16Z1CAG16 is a 16-bit CPU16 HC16 microcontroller (MCU) with a 16 MHz core clock, ROMless program memory, and 1 KB of internal RAM, housed in a 144-pin LQFP package (20x20 mm). It is part of the M68HC16 family and is code-compatible with the 68HC11 family of microcontrollers. An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU core, memory, and input/output subsystems on one die. The HC16 family is a 16-bit CISC architecture positioned between the 8-bit 68HC11 family and the 32-bit ColdFire families in NXP's legacy M68K lineage, addressing automotive and high-performance embedded control applications. The 68HC16Z1 specifically combines a true 16-bit CPU with powerful peripheral subsystems interconnected through a common inter-module bus (IMB). Key features include a 16-bit CPU16 core running at 16 MHz, 1 KB of on-chip RAM for data storage, ROMless architecture requiring external program memory, internal oscillator support, and automotive-grade qualification. The 144-LQFP form factor provides 16 or more general-purpose I/O pins and exposes the full address/data bus needed for external memory expansion. The 'CK' part designator indicates the industrial temperature grade. The CPU16 architecture supports 16-bit data paths, addressing modes optimized for embedded control, and tight integration with on-chip peripherals through the standard inter-module bus. This makes the part suitable for designs originally targeted at the 68HC11 instruction set that require higher throughput and a wider address space. Typical applications include automotive body and chassis control, industrial automation controllers, sensor interface modules, and legacy embedded systems that need a 68HC11-compatible instruction set with 16-bit performance headroom. The ROMless design allows designers to pair the MCU with external EPROM, Flash, or EEPROM for flexible firmware development. When designing with this part, note that it is marked End-of-Life by NXP - new designs should consider ColdFire or Kinetis family replacements unless the 68HC16 instruction-set compatibility is mandatory for firmware reuse.
