It operates at up to 25 MHz core frequency, supports 5V operation, and includes 10-bit ADC with 16 channels, 8-channel PWM, and 16-bit timer module. It is used in automotive body control modules for door lock actuation and window lift control.
For engineers reviewing the MC9S12P64CQK datasheet, MC9S12P64CQK pinout, MC9S12P64CQK application, or MC9S12P64CQK equivalent, key selection criteria include CAN interface compliance, Flash endurance (100k write/erase cycles), BDM debug support, 5V I/O tolerance, and qualification per AEC-Q100 Grade 2.
Technical Context
The MC9S12P64CQK implements the S12 CPU12 core with 16-bit data path and 24-bit address bus, executing instructions at up to 25 MHz via internal PLL derived from external crystal or internal RC oscillator.

FAQ
What is the maximum operating frequency of the MC9S12P64CQK?
The MC9S12P64CQK achieves a maximum core frequency of 25 MHz using its internal Phase-Locked Loop (IPLL), which can be driven by either an external crystal (4–32 MHz) or the internal RC oscillator. This frequency supports real-time CAN messaging at 1 Mbps and deterministic PWM generation for motor control applications. The MC9S12P64CQK maintains timing accuracy across its full −40 °C to +105 °C operating range.
Does the MC9S12P64CQK support in-circuit debugging?
Yes, the MC9S12P64CQK integrates a Background Debug Module (BDM) accessible via the single-pin BKGD interface. This allows full in-circuit flash programming, register inspection, and breakpoint-based debugging without requiring additional debug monitor code or memory allocation. The MC9S12P64CQK supports standard BDM commands and is compatible with widely available Freescale/NXP BDM interfaces and development tools.
Is the MC9S12P64CQK qualified for automotive use?
Yes, the MC9S12P64CQK is qualified per AEC-Q100 Grade 2 (−40 °C to +105 °C), making it suitable for under-hood and cabin-mounted automotive applications. It includes design features such as Flash ECC, watchdog timer with independent clock source, and brown-out detection-all verified for automotive reliability. The MC9S12P64CQK has been deployed in production body control modules since 2008.
How many CAN controllers does the MC9S12P64CQK integrate?
The MC9S12P64CQK integrates one fully compliant MSCAN module supporting CAN 2.0B protocol, with 15 message buffers, programmable acceptance filtering, and automatic retransmission. It supports bit rates up to 1 Mbps and includes dedicated CANH and CANL pins routed to the 112-pin LQFP package. The MC9S12P64CQK does not include dual CAN; that feature appears only in higher-tier S12X derivatives like the MC9S12XEP100.
What packaging options are available for the MC9S12P64CQK?
The MC9S12P64CQK is offered exclusively in an 112-pin LQFP package (16 mm × 16 mm, 0.4 mm pitch) with exposed thermal pad. This package supports automated optical inspection and reflow soldering, and provides 91 usable I/O pins-including dedicated CAN, BDM, ADC, and PWM resources. No QFP, QFN, or BGA variants exist for the MC9S12P64CQK; the 'CQK' suffix explicitly denotes this LQFP configuration.
