MC68332GVEH25 概要
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.

主な用途
MC68332GVEH25 の用途: 6 件s: Automotive Engine Control Units, Industrial PLC and Motion Controllers, Robotic Motion Control Systems, Avionics Flight Control Subsystems, Industrial Printer and Plotter Controllers, Medical Device Control Boards.
Automotive Engine Control Units
The MC68332GVEH25's Time Processing Unit (TPU) delivers sub-microsecond timing resolution, ideal for engine management tasks such as fuel injection pulse generation, ignition timing, and crank/cam shaft decoding. The 25 MHz CPU32 core runs control loops at the bandwidth needed for closed-loop air/fuel ratio and idle-speed stability, while the QSM's QSPI channel handles high-speed communication with external sensors and actuators. The 24-bit address bus accommodates large calibration tables typical of powertrain ECUs, and the PQFP-132 footprint supports automotive under-hood assembly with the appropriate thermal envelope.
おすすめ
Industrial PLC and Motion Controllers
The MC68332GVEH25's TPU autonomously drives stepper-motor and brushless-DC commutation patterns without CPU intervention, freeing the CPU32 core for higher-level control loops. The 16-bit external data bus provides sufficient bandwidth for I/O scanning, while the 24-bit address space allows large ladder-logic programs. Industrial PLCs benefit from the QSM's SCI/UART for Modbus or proprietary serial protocols, and the PQFP-132 footprint has been a long-standing industry-standard footprint for IEC 61131-3 controller designs.
おすすめ
Robotic Motion Control Systems
Robotic joint controllers rely on deterministic timing for synchronized multi-axis motion, and the MC68332GVEH25's TPU generates the precise pulse-width-modulated signals needed for servo drives. The CPU32 core at 25 MHz executes inverse-kinematics and trajectory-planning math in real time, while the 2 KB on-chip SRAM buffers sensor data between servo cycles. Robotic systems also use the QSM's QSPI for high-bandwidth communication with external sensor arrays (LiDAR, IMU), making this MCU a common choice in legacy industrial robotic platforms.
おすすめ
Avionics Flight Control Subsystems
Avionics subsystems benefit from the MC68332GVEH25's deterministic TPU timing for actuator control surfaces and the CPU32's M68000 instruction-set heritage familiar to legacy aerospace engineering teams. The 24-bit address bus maps large flight-control lookup tables, and the 5 V HCMOS design has a long track record in DO-178-qualified subsystems. The PQFP-132 package is suitable for chassis-mounted flight-control electronics with proper conformal coating and vibration isolation, though modern designs typically migrate to radiation-hardened parts.
おすすめ
Industrial Printer and Plotter Controllers
The MC68332GVEH25's TPU generates the precise step pulses needed to drive plotter stepper motors and print-head positioning, while the QSM's QSPI handles high-speed communication with encoder feedback. The CPU32 core at 25 MHz executes motion-planning algorithms in real time, supporting multi-axis synchronization for plotters and large-format printers. The 16-bit external data bus is well-matched to industrial-grade print engines that require moderate data throughput but high timing precision.
おすすめ
Medical Device Control Boards
Medical device controllers such as infusion pumps and diagnostic analyzers use the MC68332GVEH25 for its deterministic TPU-driven timing and 32-bit CPU32 processing power. The 2 KB on-chip SRAM provides low-latency data buffering for sensor inputs (flow sensors, optical detectors), while the QSM's SCI/UART links to host computers for data logging. The PQFP-132 footprint's long-standing medical-industry acceptance simplifies regulatory submissions for legacy device variants, and the M68000 instruction set has a documented safety track record.

設計ノート
The MC68332GVEH25 requires a regulated 5 V ± 10% supply on its VCC pins. Use a bulk 47 µF electrolytic plus 0.1 µF ceramic decoupling at each VCC pin pair to suppress the current spikes generated when the CPU32 core and TPU switch simultaneously. The HCMOS design has modest supply current but the on-chip PLL and TPU microengine can produce sharp transient loads; datasheet recommends 10 µF + 0.1 µF at each VCC/VSS pin pair to maintain voltage ripple below 100 mVpp.
Route the 24-bit address bus and 16-bit data bus with matched trace lengths to avoid setup/hold skew at 25 MHz, and place external program-memory (EPROM/flash) within 50 mm of the MCU. The PQFP-132 footprint's 0.635 mm pitch requires fine-pitch PCB manufacturing - use 4-layer stack-up with continuous ground plane under the device to minimize EMI. The TPU channel pins are timing-sensitive; keep them short and away from the QSPI clock trace.
Do not assume active 32-bit MCU substitutes are pin-compatible: according to NXP community guidance (March 2026), there is no active pin-compatible drop-in for the MC68332 family. New designs should target the MCX A Series, but this requires PCB redesign and firmware migration. For existing products, source MC68332GVEH25 only from authorized legacy distributors (Rochester Electronics) to avoid counterfeit parts - verify date codes and lot traceability before assembly.
Estimated: at 25 MHz clock and typical 5 V supply, the MC68332GVEH25 draws approximately 80-120 mA active current. With PQFP-132 theta-JA around 35-45 C/W on a 4-layer PCB, junction temperature rise above ambient is roughly 15-25 C at room temperature. Confirm thermal envelope against datasheet figure for your specific PCB layout, especially in enclosed industrial enclosures where ambient can exceed 70 C. Estimated input values: Icc = 100 mA typical, V = 5 V, theta-JA = 40 C/W.
