NXP Semiconductors MC912D60ACFUE8

Overview

MC912D60ACFUE8 from NXP Semiconductors (formerly Freescale) is a 16-bit HCS12 microcontroller featuring 60 KB on-chip Flash, 2 KB RAM, 512-byte EEPROM, 16-channel 10-bit ADC, dual CAN 2.0A/B controllers (MSCAN), 32-bit enhanced capture timer, 8-channel PWM, and multiple serial interfaces including SCI, SPI, and Freescale Interconnect Bus. It operates at up to 8 MHz core frequency with PLL support and targets automotive body control modules and industrial embedded systems.

For engineers reviewing the MC912D60ACFUE8 datasheet, MC912D60ACFUE8 pinout, MC912D60ACFUE8 application, or MC912D60ACFUE8 equivalent, key selection criteria include its 112-pin TQFP package, integrated MSCAN controllers for vehicle network communication, background debug mode (BDM) support, Flash protection features, and compatibility with legacy HC12 toolchains and development environments.

Technical Context

The MC912D60ACFUE8 implements the HCS12 CPU core with full upward compatibility to the M68HC11 instruction set and extended addressing modes. Its memory subsystem includes 60 KB of user-programmable Flash organized in 1-KB blocks with erase/write cycle endurance of 10,000 cycles, plus 512 bytes of EEPROM with selective write capability and 2 KB of static RAM.

Real-time peripherals include two independent MSCAN modules supporting CAN 2.0A/B protocols with message buffering, filtering, and low-power wake-up; an enhanced capture timer (ECT) with input capture, output compare, and pulse accumulation functions; and a 16-channel, 10-bit analog-to-digital converter with programmable sample-and-hold timing and conversion rates up to 250 kSPS.

Key Specifications

Pinout & Package

MC912D60ACFUE8 is housed in a 112-pin TQFP (case no. 987) with 0.4 mm lead pitch and 20 × 20 mm body size. Power distribution includes dedicated VDD/VSS pairs per functional block (core, I/O, ADC, CAN) to minimize noise coupling. Thermal pad is not present; thermal dissipation relies on PCB copper area under the exposed die pad region.

FAQ

What is the maximum operating frequency of the MC912D60ACFUE8?

The MC912D60ACFUE8 supports a maximum core clock frequency of 8 MHz in normal operation. When using the internal Phase-Locked Loop (PLL), the system clock can be multiplied to achieve higher bus speeds-up to 24 MHz-with appropriate loop filter design and crystal stability. All timing specifications in the datasheet assume operation within this validated range, and exceeding it may cause undefined behavior or reduced reliability.

Does the MC912D60ACFUE8 support CAN FD?

No, the MC912D60ACFUE8 does not support CAN FD. It integrates two MSCAN controllers compliant only with the classical CAN 2.0A/B protocol (ISO 11898-1:2003), supporting bit rates up to 1 Mbps. CAN FD features such as flexible data-rate switching, extended data length (up to 64 bytes), and CRC enhancements are absent in this device's CAN peripheral implementation.

How many ADC channels does the MC912D60ACFUE8 have, and what is their resolution?

The MC912D60ACFUE8 includes a single 16-channel, 10-bit analog-to-digital converter (ATD). Each channel supports programmable sample time, conversion trigger sources (software, timer, or external), and configurable reference voltage selection (VDDA or internal bandgap). The effective resolution remains 10 bits across all channels, with typical INL of ±1 LSB and DNL of ±0.5 LSB per the Rev. 3.1 datasheet.

Is the MC912D60ACFUE8 pin-compatible with other HCS12 devices like the MC912D60C or MC912D60P?

No, the MC912D60ACFUE8 is not pin-compatible with MC912D60C or MC912D60P. While all three share the same 112-pin TQFP mechanical footprint, their oscillator configurations differ: MC912D60ACFUE8 uses a Colpitts oscillator (requiring external capacitors), MC912D60C also uses Colpitts but with different capacitor values, and MC912D60P uses a Pierce oscillator. These differences affect XTAL/EXTAL pin behavior and external component requirements, preventing direct substitution without schematic and layout review.

What debug interface does the MC912D60ACFUE8 support?

The MC912D60ACFUE8 supports Background Debug Mode (BDM) via a single-wire serial interface using the BKGD pin. This allows non-intrusive debugging-including real-time register and memory inspection, breakpoint insertion, and Flash programming-without requiring dedicated JTAG pins or halting the CPU clock. BDM operation is enabled by asserting MODA=0 and MODB=1 at reset, and requires a compatible BDM pod or debugger such as the P&E Micro BDM12.
