MC912DG128AVPV-FR 개요
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one package. The MC912DG128AVPV-FR belongs to the M68HC12 family and uses a 16-bit CPU12 architecture. Within the system hierarchy, it sits between a general-purpose embedded controller and a specialized application processor: firmware executes from internal flash, peripheral modules handle external events, and the ADC channels acquire analog measurements for control or monitoring.
Verified features emphasize integration rather than a high-pin-count peripheral ecosystem. The 128 KB flash provides substantially more program storage than many small 8-bit controllers, while 8 KB of RAM supports working variables and protocol buffers. Two SCI channels support serial communications, SPI supports synchronous peripheral connections, I2C supports low-speed board-level devices, and the dual 10-bit ADC structure makes the MCU suitable for mixed-signal monitoring. The listed operating supply range is 4.5 V to 5.5 V.
The -FR ordering code corresponds to the Rochester Electronics source identified in the verified marketplace record, while the base device is associated with NXP in the datasheet results. Rochester’s record reports one unit per package and MSL Level 3, with a 168-hour floor-life classification. Because this is a mature embedded-control MCU, firmware, peripheral configuration, clocking, reset behavior, electrical limits, and package details must be validated against the complete manufacturer documentation before production release.
Typical uses include industrial equipment interfaces, automotive-style body and chassis controllers, data acquisition units, serial gateways, and compact embedded control panels. The MCU can coordinate ADC measurements with serial transceivers and nonvolatile storage while its 69 I/O lines operate external sensors, indicators, and interlocks. Its 5 V supply range suits established 5 V industrial architectures, provided the complete board respects the device’s input and I/O limits.
A successful design should reserve all 112 package pins according to the official pinout and distinguish power, ground, clock, reset, analog, and communication functions during routing. PCB signal-integrity and decoupling decisions should be based on the complete datasheet rather than inferred from marketplace summaries. Legacy firmware should also be tested for compatibility with the exact die revision and production source.
This page consolidates the verified NXP family data, Rochester Electronics sourcing record, distributor package information, and transparent replacement analysis. It distinguishes documented production sourcing from unverified substitute claims and avoids presenting generic 16-bit microcontrollers as drop-in replacements.

일반적인 애플리케이션
MC912DG128AVPV-FR 적합 용도: 6 애플리케이션s: Industrial Equipment Interface Controller, Automotive Chassis and Body Control, Serial Data Acquisition Unit, Serial Gateway and Protocol Bridge, Data Logger with Nonvolatile Configuration, Compact Embedded Control Panel.
Industrial Equipment Interface Controller
The MC912DG128AVPV-FR fits a 5 V industrial interface controller because its 8 MHz CPU12 can coordinate 69 GPIO lines with two 10-bit, eight-channel ADC banks while retaining substantial code in 128 KB of flash. The device can poll sensors, operate interlocks, and manage external relays through its digital I/O. Its two SCI channels are useful for operator consoles or service ports, while SPI and I2C can connect local data-acquisition or storage devices. The engineering trade-off is that the operating-temperature range was not verified, so qualification must precede deployment in temperature-critical machinery.
추천
Automotive Chassis and Body Control
The MC912DG128AVPV-FR is architecturally suitable for a 5 V vehicle body or chassis controller because it combines 69 GPIO lines, two 10-bit ADC banks, serial communications, and a 5 V operating range in one LQFP-112 package. Firmware can consolidate switch inputs, analog sensing, actuator control, and diagnostic communication without requiring several discrete controllers. However, the verified data does not establish automotive qualification, temperature limits, transient immunity, or functional-safety status, so it should not be used as evidence of AEC-Q100 suitability or production automotive approval.
추천
Serial Data Acquisition Unit
The MC912DG128AVPV-FR can serve as the acquisition and communications hub in a compact serial data logger because its dual ADC structure provides 16 total 10-bit channels, while two SCI modules support separate serial links. Its 128 KB flash provides room for calibration tables, buffering, and application firmware, and the 8 KB RAM supports control state and communication buffers. SPI may connect a higher-speed conversion or storage device, although analog front-end design still requires suitable excitation, filtering, grounding, and input-protection circuits for the measured signals.
추천
Serial Gateway and Protocol Bridge
The MC912DG128AVPV-FR is suited to a legacy serial gateway because two SCI modules can terminate independent communication links and the CPU12 firmware can translate, filter, or supervise the traffic. Its 128 KB flash, 8 KB RAM, and 2 KB EEPROM provide room for protocol tables, configuration data, and buffered messages, while 69 GPIO lines support status indicators and control signals. The gateway remains dependent on exact baud-rate, electrical-level, timing, and peripheral specifications from the full manufacturer documentation because those details are absent from the supplied marketplace excerpts.
추천
Data Logger with Nonvolatile Configuration
The MC912DG128AVPV-FR can retain operating parameters in its 2 KB of EEPROM and place firmware in 128 KB of flash, making it suitable for an embedded data logger that must restore calibration or device settings after power loss. Two SCI channels can support host communication and an external sensor, while the ADC banks handle analog inputs. Designers should verify EEPROM endurance, retention, write timing, and data integrity from the complete documentation and should add external nonvolatile storage if the application requires more capacity than the internal 2 KB.
추천
Compact Embedded Control Panel
The MC912DG128AVPV-FR can coordinate a compact control panel because its 69 GPIO lines can operate keys, indicators, relays, and discrete sensors while the two SCI channels support a local operator interface. The 10-bit ADC banks provide mixed-signal inputs, and the 4.5 V to 5.5 V supply range fits established 5 V panel electronics. Layout planning must account for all 112 LQFP pins, but because the complete pin table was not supplied, no pin should be assigned solely from the package image. Prototype firmware should also validate debounce, isolation, and actuator-driver behavior before direct field wiring.

주요 차별점
- Large integrated memory for a mature 16-bit embedded controller (vs Small 8-bit microcontroller designs)
- Broad mixed-signal and serial peripheral set (vs GPIO-focused small-format controllers)
- High GPIO count for legacy embedded panels (vs Lower-pin-count microcontrollers)
설계 노트
Design the board around the verified 4.5 V to 5.5 V operating range and verify every absolute maximum rating from the complete manufacturer document. Place the required bypass capacitors at the device supply pins with very short ground returns, and separate analog and digital return paths carefully where ADC inputs are used. Do not infer recommended capacitance, current limits, or pin names from the LCPCB summary.
The MC912DG128AVPV-FR uses an LQFP-112 package, so footprint correctness depends on the complete pin table and mechanical drawing. Confirm pin 1 orientation, pin pitch, body size, solder-mask clearance, and land pattern before fabrication. Maintain serviceable routing away from package edges and provide clear ground reference beneath the device unless the complete application guidance specifies otherwise.
The two 8-channel, 10-bit ADC banks make analog layout important even though the final sampling network is not specified. Route analog inputs away from clock, SCI, SPI, and switching-power traces; use a quiet ground reference; add input filtering matched to the required bandwidth; and validate source impedance. These are design practices rather than verified MC912DG128AVPV-FR specifications and must be checked against the full electrical documentation.
Do not treat the related MC912DG128AVPV, MC912DG128AVPVE, or MC912DG128ACPVE listings as confirmed substitutes without checking the complete ordering table. CPU12 family similarity does not guarantee speed grade, temperature range, package pinout, mask revision, or software compatibility. Likewise, a distributor listing alone does not prove current stock; obtain traceability, date code, condition, warranty, and lifecycle confirmation before production use.
규정 준수 정보
The Rochester Electronics listing reports REACH status as vendor undefined. No verified RoHS, AEC-Q100, lead-free, halogen-free, or conflict-minerals statement was supplied, so all unspecified fields remain unknown.
