Product details
Overview
MC912DT128CCPVE from Freescale Semiconductor is a 16-bit HCS12 microcontroller featuring 128 KB on-chip flash memory, 4 KB RAM, and integrated CAN 2.0A/B controller (MSCAN), PWM, ECT, ATD, SPI, SCI, and I²C interfaces. It operates at up to 25 MHz core frequency with PLL-based clock generation and targets automotive body control, industrial sensor nodes, and embedded motor control systems.
For engineers reviewing the MC912DT128CCPVE datasheet, MC912DT128CCPVE pinout, MC912DT128CCPVE application, or MC912DT128CCPVE equivalent, this page delivers verified technical context, package-specific pin definitions, real-world use cases, and validated alternative parts for design-in and long-term supply planning.
Technical Context
The MC912DT128CCPVE implements the HCS12 CPU core with 16-bit data/24-bit address bus, supporting background debug mode (BDM) for in-circuit emulation. Its MSCAN module provides full CAN 2.0A/B compliance with 16 message buffers, programmable acceptance filtering, and low-power wake-on-CAN capability.
It integrates dual 10-bit analog-to-digital converters (ATD0/ATD1) with 8/16-channel multiplexing, 8-channel PWM with center/left-aligned modes, and an enhanced capture timer (ECT) with input capture, output compare, and pulse accumulation functions - all synchronized to a single PLL-derived system clock.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S12XDP512 | Successor HCS12X device with 512 KB flash, XGATE coprocessor, and enhanced CAN FD readiness; requires PCB layout changes due to 112-pin LQFP → 144-pin LQFP upgrade. | Higher code density and offload capability for complex communication stacks; not drop-in compatible. | Select when future-proofing for CAN FD or requiring >128 KB flash; migration requires pinout and toolchain adaptation. |

FAQ
What is the maximum operating frequency of the MC912DT128CCPVE?
The MC912DT128CCPVE achieves a maximum core frequency of 25 MHz using its on-chip PLL, which multiplies an external crystal input (typically 4–8 MHz). This frequency is sustained across the full industrial temperature range (−40°C to +85°C) and supports deterministic real-time execution for motor control and communication protocols.
Does the MC912DT128CCPVE support CAN FD?
No, the MC912DT128CCPVE features the MSCAN controller compliant only with CAN 2.0A/B (ISO 11898-1) up to 1 Mbit/s. It does not support CAN FD data rates, arbitration bit rate flexibility, or extended data length frames. For CAN FD, consider the later S912XDP512 or S32K series from NXP.
How many analog input channels does the MC912DT128CCPVE support?
The MC912DT128CCPVE integrates two independent 10-bit analog-to-digital converters: ATD0 supports 8 analog inputs (PA0–PA7), and ATD1 supports 16 analog inputs (PD0–PD7 and additional pins mapped to PORTK). Both converters can operate simultaneously with configurable sample-and-hold timing.
Is the MC912DT128CCPVE pin-compatible with the MC68HC912DT128A?
Yes, the MC912DT128CCPVE is a direct replacement for the MC68HC912DT128A in the same 112-pin LQFP package. It maintains identical pinout, electrical characteristics, and instruction set compatibility while incorporating mask-set improvements including enhanced oscillator stability and flash protection features.
What debug interface does the MC912DT128CCPVE use?
The MC912DT128CCPVE uses the Background Debug Mode (BDM) interface - a single-wire serial protocol accessible via the BKGD pin. BDM enables non-intrusive debugging, flash programming, and real-time register access without requiring dedicated JTAG pins or halting peripheral operation.
