Product details
Overview
MC9S12C64VFUE from NXP (formerly Freescale) is a 16-bit HCS12 microcontroller featuring 64 KB on-chip Flash, 4 KB RAM, and integrated CAN 2.0A/B controller, PWM, 10-bit 8-channel ADC, and BDM debug interface. It operates at up to 25 MHz core frequency with internal PLL, supports automotive-grade temperature range (–40°C to +105°C), and targets engine control units, body electronics, and industrial motor control.
For engineers reviewing the MC9S12C64VFUE datasheet, MC9S12C64VFUE pinout, MC9S12C64VFUE application, or MC9S12C64VFUE equivalent, key selection criteria include its 80-pin LQFP package, S12 CPU core compatibility, CAN bus timing compliance, Flash endurance (10k erase/write cycles), and legacy toolchain support (CodeWarrior IDE, P&E Multilink).
Technical Context
The MC9S12C64VFUE implements the S12 CPU core with 16-bit data path, Harvard architecture, and 24-bit addressing. It integrates a scalable CAN controller (S12MSCANV2) supporting both standard and extended frames, plus a 16-bit timer module (TIM16B8CV1) with input capture, output compare, and PWM generation capabilities.
Its clock system includes a PLL-based frequency synthesizer (CRGV4), dual voltage regulators (VREG3V3V2), and low-power modes (WAIT/STOP). Memory mapping uses PPAGE banking for >64 KB address space expansion, and the Background Debug Module (BDMV4) enables single-wire in-circuit debugging without halting real-time operation.

FAQ
What is the maximum operating frequency of the MC9S12C64VFUE?
The MC9S12C64VFUE achieves a maximum core frequency of 25 MHz using its internal PLL, which multiplies an external 4–8 MHz crystal input. This frequency is sustained across the full –40°C to +105°C operating range and supports deterministic real-time execution for automotive control loops.
Does the MC9S12C64VFUE support CAN FD?
No, the MC9S12C64VFUE implements the legacy S12MSCANV2 module compliant only with CAN 2.0A/B (ISO 11898-1), supporting bit rates up to 1 Mbps. It does not support CAN FD features such as flexible data-rate, larger payloads, or CRC enhancements.
Is the MC9S12C64VFUE pin-compatible with other HCS12 derivatives?
Yes - the MC9S12C64VFUE shares identical 80-pin LQFP pinout and signal mapping with MC9S12C128VFUE and MC9S12C96VFUE, enabling hardware reuse across memory variants within the same C-family generation.
What debug tools are supported for the MC9S12C64VFUE?
The MC9S12C64VFUE is fully supported by P&E Micro's Multilink Universal and Cyclone Pro debug probes, as well as legacy CodeWarrior Development Studio v5.1–v5.10. Its BDMV4 module enables flash programming, live register inspection, and non-intrusive breakpoints without requiring JTAG headers.
How is Flash memory endurance specified for the MC9S12C64VFUE?
The MC9S12C64VFUE's 64 KB Flash (S12FTS64KV4) is rated for 10,000 erase/write cycles per sector and guarantees 10 years of data retention at +85°C. Endurance is validated per JEDEC JESD22-A117 and applies to all sectors, including those used for EEPROM emulation.
