MC912DG128AVPVE 개요
A microcontroller is a programmable integrated circuit containing a processor core, nonvolatile program memory, data memory, input/output ports, and peripherals on one semiconductor device. The MCU12 family belongs to the broader embedded-controller hierarchy: MCU12 device, 16-bit microcontroller, embedded processor, and semiconductor. MC912 devices combine bus-oriented control logic with resources intended for body, powertrain-adjacent, and industrial-style embedded systems.
The verified device data identifies 128KB of flash organized as 128K x 8, 8K x 8 RAM, 69 I/O pins, an 8 MHz maximum speed, and a 112-pin LQFP package. Cross-reference results also describe two analog-to-digital converters, an enhanced capture timer, four PWM channels, serial interfaces, LIM, two 8-bit ports, key-wakeup interrupt capability, and clock generation. These integrated resources can reduce external component count in applications requiring several control and communication functions.
The CPU12 architecture uses a 16-bit instruction set and provides a practical balance between computational capability, deterministic embedded control, and integration. Because exact peripheral assignments, electrical limits, memory-map details, and timing characteristics were not supplied in the verified excerpts, engineers should confirm them in the manufacturer datasheet and MC912 reference manual before final PCB release or firmware deployment. The end-of-life status makes lifecycle planning especially important.
Typical automotive uses include body-control modules, actuator and motor-control logic, sensor-interface systems, embedded gateways, and compact powertrain-adjacent controllers. The 69 I/O count supports devices that need substantial discrete signal routing, while PWM and capture timers support switching, timing, and input-capture tasks. Serial interfaces can connect the MCU to sensors, transceivers, or other controllers.
For a new design, confirm that the required 112-pin land pattern, 5 V supply, 8 MHz clocking, memory requirements, peripheral mix, and software toolchain remain supported by the selected product. For an existing MC912DG128AVPVE design, preserve the original footprint and firmware assumptions unless NXP provides a formal replacement. This page combines verified product-page, distributor, and cross-reference information with procurement-oriented guidance.
The part is listed as end of life on NXP's official product page, so supply continuity and long-term sourcing should be confirmed with NXP or an authorized distributor. Distributor listings may still show inventory or pricing, but those listings do not override the manufacturer's lifecycle designation. The 5 V operating value, 8 MHz speed, memory organization, and 112-LQFP package are retained exactly where provided; additional electrical details remain to be verified.

일반적인 애플리케이션
MC912DG128AVPVE 적합 용도: 6 애플리케이션s: Automotive Body-Control Module, Actuator and Relay Control, Sensor Interface and Data Acquisition, Embedded Communication Gateway, Powertrain-Adjacent Control, Industrial-Style Embedded Controller.
Automotive Body-Control Module
MC912DG128AVPVE is a reasonable candidate for a body-control module because the verified device combines a 16-bit CPU12 core, 128KB flash, 8K x 8 RAM, 69 I/O pins, and integrated 5 V operation in a 112-LQFP package. Its I/O capacity can support switch inputs, lamp outputs, relay drivers, and communication links within one controller. The four PWM channels may serve indicator, flap, or actuator timing functions, while the two ADCs can monitor resistive sensor inputs when the required accuracy and sampling behavior are confirmed. Because the part is end of life and no AEC-Q100 status was provided, production automotive use requires qualification review, traceability review, and confirmation of all electrical and temperature limits in the manufacturer documentation.
추천
Actuator and Relay Control
The MC912DG128AVPVE fits actuator and relay-control designs that need many digital signals and deterministic embedded timing. Its 69 I/O pins provide a substantial external signal budget, while the four PWM channels can be used for repetitive control or diagnostic functions where the exact timing limits are suitable. The two analog-to-digital converters can monitor feedback from position, pressure, or current-related sensors through appropriate external conditioning. Use the 5 V supply reference and 8 MHz CPU speed as the verified baseline, but verify drive-current limits, pin multiplexing, timing resolution, and protection requirements before connecting loads. External transistors, flyback protection, and logic-level interfaces may be required because MCU I/O ratings do not establish direct-load capability.
추천
Sensor Interface and Data Acquisition
MC912DG128AVPVE can be evaluated for sensor acquisition because it includes two analog-to-digital converters alongside a 16-bit CPU12 core and 128KB flash for program storage. The 69 I/O count supports digital status inputs, sensor-enable signals, communications, and local diagnostics. In a typical implementation, conditioned analog signals enter the ADC channels while the MCU performs filtering, thresholding, calibration, and status reporting through its serial interfaces. The verified material does not specify ADC resolution, sample rate, input range, accuracy, or acquisition timing, so those values must be obtained from the NXP datasheet before setting the analog front end. Keep analog and digital return paths controlled and confirm whether the 5 V device requires external level shifting for lower-voltage sensors.
추천
Embedded Communication Gateway
The integrated serial interfaces and 69 I/O pins make MC912DG128AVPVE applicable to a small embedded gateway that coordinates sensors and actuators. The MCU can potentially handle protocol processing, local state-machine control, diagnostics, and signal bridging while the 128KB flash stores firmware. Its 16-bit CPU12 architecture and 8 MHz speed are appropriate for many low-bandwidth embedded coordination tasks, but interface protocol rates, framing modes, timing tolerances, and DMA or interrupt behavior were not supplied. The designer should confirm which serial peripherals are available on the exact package pins and whether external transceivers are needed. Because the device is end of life, an existing gateway design can evaluate a related MC912 part, but a new product should not proceed without a documented supply and lifecycle plan.
추천
Powertrain-Adjacent Control
MC912DG128AVPVE may be considered for a powertrain-adjacent auxiliary controller that monitors discrete and analog signals and coordinates limited actuator functions. The verified combination of 16-bit processing, 128KB flash, 8K x 8 RAM, 69 I/O pins, PWM channels, and ADCs provides a broad embedded-control foundation. It is not enough by itself to establish suitability for safety-critical powertrain control: the provided data does not confirm AEC-Q100 qualification, temperature limits, functional-safety support, diagnostics coverage, or transient performance. Use the part only within the exact manufacturer ratings and system safety case. External power electronics, sensing networks, isolation, and protection circuitry will likely define the actual application boundary.
추천
Industrial-Style Embedded Controller
Although the verified product information does not provide a current industrial lifecycle statement, MC912DG128AVPVE's 16-bit CPU, 128KB flash, 69 I/O pins, integrated clock generation, and 112-LQFP package make it suitable for evaluation in legacy industrial equipment that already depends on the MC912 platform. It can supervise discrete sensors, operate relays, run local control loops, and communicate with external modules. The 5 V reference and 8 MHz speed define the baseline electrical and timing context, while the MCU12 architecture helps preserve compatibility with existing software. New industrial designs should account for the end-of-life designation, availability, temperature range, electromagnetic compatibility, and long-term obsolescence planning before committing to this legacy MCU.

설계 노트
Treat the verified 5 V value as the nominal supply reference and confirm the complete allowed voltage range, current limits, startup behavior, and decoupling requirements in the NXP datasheet before laying out the power tree. Place bulk and high-frequency decoupling close to the appropriate supply and ground pins, and keep switching-converter traces away from sensitive analog inputs. Estimated power dissipation cannot be calculated from the supplied data because core current, I/O load current, and clock configuration are not provided.
The 112-LQFP footprint has fine pitch and requires careful fanout, solder-mask control, and thermal-via planning. Confirm the exact NXP land pattern and pin numbering rather than inferring it from the generic LQFP name. Keep the 5 V distribution and ground return paths short, route analog inputs away from PWM and serial edges, and provide a stable ground reference for both ADC-capable circuits and communication interfaces.
Do not assume that a related 112-pin MC912 device is a drop-in replacement solely because the package and CPU family match. Verify pin multiplexing, reset behavior, oscillator connections, supply tolerances, ADC channels, timer assignments, memory map, and firmware startup code against the original design. The supplied cross-reference results identify related parts but do not provide a complete pin-level equivalence report.
Use the manufacturer's package thermal information for the final junction-temperature and ambient-temperature calculation. The supplied data does not include thermal resistance, maximum junction temperature, or the operating temperature range, so a numeric thermal estimate would be unsupported. Even at 8 MHz and 5 V, validate the actual board copper, enclosure temperature, I/O loading, and supply dissipation under worst-case conditions before production release.
규정 준수 정보
The supplied manufacturer and distributor excerpts do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance and automotive qualification must be confirmed using current NXP documentation before production release.
