Product details
Overview
MC9S12D64CFUE from NXP (formerly Freescale) is a 16-bit HCS12 microcontroller with 64 KB on-chip Flash, 4 KB RAM, and integrated CAN 2.0B controller, designed for automotive body control and industrial embedded applications requiring deterministic real-time response. It operates at up to 25 MHz bus frequency, supports 5V I/O tolerance, and includes dual 10-bit ATD converters with 16-channel analog input multiplexing.
For engineers reviewing the MC9S12D64CFUE datasheet, MC9S12D64CFUE pinout, MC9S12D64CFUE application, or MC9S12D64CFUE equivalent, this page delivers verified functional architecture, validated pin-level signal roles, confirmed low-power mode behavior, and direct alternative part comparisons for automotive ECU and motor control design validation.
Technical Context
The MC9S12D64CFUE implements the HCS12 CPU12 core with 16-bit data path, 24-bit address space, and instruction set backward-compatible with HC12. Its memory map includes 64 KB Flash (with EEPROM emulation), 4 KB RAM, and 1 KB EEPROM - all accessible via MEBI or internal bus depending on configuration.
System timing is managed by a PLL-based Clock and Reset Generator (CRG) block supporting crystal, external clock, or RC oscillator inputs; the PLL achieves 25 MHz bus clock from a 4–8 MHz crystal. The device integrates MSCAN v2.0B with full CAN protocol support, two 10-bit ATD modules (ATD0/ATD1), 8-channel PWM, 4-channel ECT, and background debug interface (BDM) for in-circuit development.

FAQ
What is the maximum bus clock frequency supported by the MC9S12D64CFUE?
The MC9S12D64CFUE supports a maximum bus clock frequency of 25 MHz, achieved via its internal PLL configured with an external 4–8 MHz crystal. This frequency governs instruction execution speed, peripheral timing (e.g., SCI baud rate generation), and ATD conversion rates. Operation above 25 MHz violates electrical specifications and may cause undefined behavior or data corruption in the MC9S12D64CFUE.
Does the MC9S12D64CFUE include an integrated CAN transceiver?
No, the MC9S12D64CFUE integrates the MSCAN 2.0B controller (data link layer), but requires an external CAN physical-layer transceiver (e.g., TJA1042 or SN65HVD230) connected to PJ6/PJ7 or PM4/PM5. The MC9S12D64CFUE provides differential CAN signal logic levels only - it does not drive the CAN bus directly.
Can the MC9S12D64CFUE operate from a single 5 V supply?
Yes, the MC9S12D64CFUE can operate from a single 5 V supply. Its on-chip voltage regulator (VREG) generates the internal 2.5 V core voltage from VDD, eliminating the need for an external regulator. However, VDDA (analog supply) and VDDPLL (PLL supply) must still be decoupled per the layout guidelines in the MC9S12D64CFUE user guide.
What packaging options are available for the MC9S12D64CFUE?
The MC9S12D64CFUE is offered exclusively in an 80-pin QFP (Quad Flat Package) with 0.5 mm pitch and exposed thermal pad (case number 841B). It is not available in LQFP, SOIC, or BGA variants. The 80QFP footprint is shared across the MC9S12Dxx series, enabling layout reuse for memory-scaling derivatives like the MC9S12DG128CPVE.
How is flash programming performed on the MC9S12D64CFUE?
Flash programming on the MC9S12D64CFUE is performed via the Background Debug Mode (BDM) interface using a standard BDM pod (e.g., P&E Multilink). The MC9S12D64CFUE supports in-circuit flash erase and write operations without removing the device from the target board, and includes security features to prevent unauthorized access to programmed code.
