MC912DT128AVPVE 概要
A microcontroller is a programmable semiconductor device that combines a CPU core with memory and peripherals on one integrated circuit. The CPU12 executes embedded control software, while flash EEPROM retains firmware, RAM supports working data, and EEPROM preserves configuration or calibration values. This MC912DT128A-family device is positioned within the hierarchy of embedded processors, microcontrollers, and automotive semiconductor control systems.
The verified product information identifies a 16-bit CPU12 architecture, 8 MHz operation, 128 KB flash EEPROM, and a 112-LQFP package. The device family also provides 8 KB RAM, 2 KB EEPROM, two analog-to-digital converter banks, two asynchronous SCI peripherals, SPI, I2C, enhanced capture timer, PWM channels, and three 1 Mbit/s CAN 2.0 modules. These resources support concurrent digital control, sensor acquisition, and network communication.
Automotive-oriented part coding and AEC-Q100 identification are reported by the verified distributor data, while the component is offered in a tray. The three CAN controllers are especially important for body, powertrain-adjacent, industrial automation, and transportation systems where distributed nodes must exchange real-time data. Serial interfaces provide additional paths to sensors, actuators, diagnostics equipment, and external controllers.
Use the MCU in applications such as electronic control units, body modules, motor and actuator controllers, CAN gateways, industrial automation controllers, and embedded sensing platforms. The 8 MHz CPU12 and broad peripheral set allow firmware to combine communication, timing, and analog supervision in one device. Verify clock, memory, electrical, temperature, and qualification details against the manufacturer datasheet before production release.
The primary design consideration is PCB integration in the 112-pin LQFP package. Its fine-pitch leads and automotive supply-voltage environment require careful power distribution, decoupling, grounding, signal-integrity review, and thermal validation. A hardware-in-the-loop test should verify CAN timing, startup behavior, peripheral contention, and firmware migration before production.
This product page consolidates verified distributor specifications, pricing, sourcing links, and design-oriented context. It does not substitute for the complete NXP datasheet, errata, reference manual, or application validation required for safety-critical automotive deployment.

主な用途
MC912DT128AVPVE の用途: 6 件s: Automotive Body Control Module, CAN Gateway Controller, Motor and Actuator Control, Industrial Automation Controller, Vehicle Sensor Hub, Diagnostics and Communication Node.
Automotive Body Control Module
The MC912DT128AVPVE fits a body-control node because its 8 MHz CPU12 can supervise switching and sensing functions while three 1 Mbit/s CAN modules serve distributed vehicle networks. The 128 KB flash EEPROM provides room for application firmware, and 8 KB of RAM supports active control state. Two ADC banks can monitor analog inputs, while ECT and four PWM channels support periodic sensing and actuator drive. Because the exact MCU is supplied in a 112-pin LQFP and identified for automotive use, it supports established high-pin-count ECU layouts. Final deployment still requires schematic pin verification, device revision checks, EMC testing, and validation against the applicable automotive qualification requirements.
おすすめ
CAN Gateway Controller
A CAN gateway is a strong fit because the MC912DT128AVPVE provides three CAN modules rated up to 1 Mbit/s. One controller can terminate an internal vehicle bus while the others bridge external or diagnostic networks, reducing the need for separate communication devices. Its CPU12 core and 128 KB flash EEPROM can host protocol translation, filtering, diagnostics, and fault-management firmware. The three channels are especially useful where a node must exchange body, powertrain-adjacent, or diagnostic traffic. Hardware design must add the correct CAN transceivers, termination, isolation where required, protected routing, and validated bus timing before production use.
おすすめ
Motor and Actuator Control
The MC912DT128AVPVE can control timing-sensitive actuators because its 8 MHz CPU12, enhanced capture timer, four PWM channels, and ADC inputs provide a combined real-time control path. Firmware can decode sensor timing, calculate a control response, and update PWM outputs while CAN carries commands and diagnostic data. The 128 KB flash EEPROM and 8 KB RAM support moderate protocol and control stacks, while two SCI ports permit communication with external drivers or sensors. Actual motor-drive suitability depends on operating temperature, electrical limits, output drive topology, and safety requirements that are not fully present in the verified snippets. Power stages and protection must therefore be designed separately.
おすすめ
Industrial Automation Controller
For industrial automation, the MC912DT128AVPVE combines three CAN channels with SPI, I2C, two SCI interfaces, ADC capability, timers, and PWM outputs. That peripheral mix supports a compact controller that gathers sensor data, drives outputs, and communicates across a distributed bus. Its 112-LQFP package offers many external pins but requires careful escape routing and multilayer placement to preserve signal integrity. Firmware inherited from HC12-family automotive designs may reduce migration effort, although the operating environment and qualification obligations differ from industrial requirements. Validate EMC, temperature behavior, watchdog coverage, recovery logic, and long-term supply before deploying it as a standard plant controller.
おすすめ
Vehicle Sensor Hub
The MC912DT128AVPVE can consolidate vehicle sensor inputs because it includes two analog-to-digital converter banks alongside SPI, I2C, SCI, timers, and three CAN controllers. A hub firmware can sample conditioned sensor signals, timestamp events with the enhanced capture timer, filter data locally, and forward selected measurements over CAN. The 128 KB flash EEPROM accommodates configuration tables and application code, while 8 KB RAM is sufficient for bounded buffering and protocol work. Because the target is supplied in an automotive tray and identified as AEC-Q100 in distributor data, it fits legacy or established qualified platforms. Sensor accuracy, channel multiplexing, diagnostics, and calibration must be validated from the complete manufacturer documentation.
おすすめ
Diagnostics and Communication Node
Three CAN modules make the MC912DT128AVPVE suitable for a communications node that handles diagnostic traffic alongside two additional bus segments. Its two SCI ports support legacy service interfaces, while SPI and I2C can connect to local transceivers, storage, or sensors. The CPU12 executes at 8 MHz and has 128 KB of flash EEPROM for gateway firmware, message filtering, counters, and diagnostic services. A practical design must configure bus clocks and timers correctly, verify termination at both ends, and stress-test arbitration, fault recovery, and bus-off behavior. Automotive suitability also depends on the exact device grade, temperature limits, and manufacturer errata, which are not included in the supplied snippets.

設計ノート
Treat the MC912DT128AVPVE as a 112-pin LQFP layout problem rather than a generic MCU placement. Preserve the manufacturer's land pattern and pin-1 orientation, and place power, ground, decoupling, and protection components according to the complete NXP reference design. Because the supplied snippets do not contain the complete pin table or recommended layout, engineers must verify every multiplexed signal and power domain against the exact device revision before release.
Design the 5 V supply rail from verified electrical limits rather than the distributor headline alone. Place local high-frequency and bulk decoupling at the associated MCU supply pins, provide clean return paths, and account for automotive or industrial input transients with appropriately selected protection. Validate startup sequencing, voltage tolerances, current budget, and analog-supply noise using the manufacturer datasheet and worst-case board measurements.
The three CAN channels make trace and topology planning essential. Use the NXP reference layout or equivalent geometry, keep sensitive timing and analog routes away from high-current edges, preserve continuous ground references under the QFP, and verify connector protection. CAN bus parameters, termination, transceiver loopback, propagation delay, arbitration, and fault recovery must be tested together because a package-compatible replacement does not guarantee identical timing behavior.
Do not substitute a related DG or ACP suffix solely because it has 112 pins. The verified evidence shows the DG devices can have two CAN modules instead of three, and unreported differences may involve memory, pin multiplexing, timers, clocking, qualification, or software initialization. Confirm the exact ordering code, datasheet revision, errata, pin table, and firmware behavior before treating any listed alternative as a true drop-in replacement.
