NXP Semiconductors MC9S12C64MPBE

Overview

MC9S12C64MPBE 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 5V tolerant I/O and supports automotive-grade temperature range (−40°C to +125°C). It targets engine control units, body electronics, and industrial motor control systems requiring deterministic real-time response.

For engineers reviewing the MC9S12C64MPBE datasheet, MC9S12C64MPBE pinout, MC9S12C64MPBE application, or MC9S12C64MPBE equivalent, this page delivers verified electrical specs, package mapping (112-pin LQFP), functional module dependencies, and validated alternative options for EOL mitigation and design continuity in safety-critical embedded systems.

Technical Context

The MC9S12C64MPBE implements the S12 CPU core with 16-bit data/24-bit address bus, supporting banked memory architecture via PPAGE register and external bus interface (MEBI) for expansion. Its clock system integrates a PLL with selectable dividers, enabling flexible core/bus clock ratios (e.g., 25 MHz core / 25 MHz bus).

Peripheral integration includes a scalable CAN controller (S12MSCANV2) with 15 message buffers, 8-channel 10-bit ATD converter with configurable sample-and-hold timing, and dual 8-bit PWM modules (PWM8B6CV1) with independent dead-time insertion and center-aligned mode support.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MC9S12C64MPBE?

The MC9S12C64MPBE supports a maximum core clock frequency of 25 MHz, achieved using its integrated Phase-Locked Loop (PLL) with configurable pre-divider and post-divider settings. The bus clock runs synchronously at the same frequency, enabling deterministic instruction execution and peripheral timing. This 25 MHz limit is specified across the full −40°C to +125°C temperature range and 4.5–5.5 V supply voltage.

Does the MC9S12C64MPBE support CAN FD?

No, the MC9S12C64MPBE implements the S12MSCANV2 module, which is compliant only with CAN 2.0A/B (ISO 11898-1) and does not support CAN FD features such as flexible data-rate or extended data length. For CAN FD capability, designers must consider newer derivatives like the MC9S12XEP100 series, which include updated CAN controllers with FD support.

How is flash programming performed on the MC9S12C64MPBE?

Flash programming on the MC9S12C64MPBE is performed via the Background Debug Module (BDMV4) using a single-wire BKGD interface and standard Freescale BDM protocol. The S12FTS64KV4 Flash module supports sector erase (2 KB granularity), byte/word programming, and in-application programming (IAP) with protected write sequences. No external high-voltage supply is required.

What debug interfaces does the MC9S12C64MPBE provide?

The MC9S12C64MPBE provides the Background Debug Module (BDMV4) as its primary debug interface-supporting full-speed execution control, register inspection, memory read/write, and flash programming via the BKGD pin. It does not include JTAG or SWD; BDM is the only standardized debug path, requiring compatible tools such as P&E Multilink or SEGGER J-Link with BDM firmware.

Is the MC9S12C64MPBE pin-compatible with other MC9S12C family members?

Yes, the MC9S12C64MPBE shares the same 112-pin LQFP package and pinout with other MC9S12C variants in the same package option (e.g., MC9S12C128MPBE), differing only in Flash/RAM size and enabled peripherals. Pin compatibility allows direct substitution within the same package group, provided firmware accounts for memory map and module enable differences.
