Product details
Overview
MC9S12DG256MPVE from Freescale Semiconductor is a 16-bit automotive-grade microcontroller featuring 256KB Flash EEPROM, 12KB RAM, 4KB EEPROM, dual 10-bit ADCs (16-channel total), two CAN 2.0A/B modules, and an enhanced capture timer (ECT). It operates at up to 50MHz core frequency (25MHz bus speed) in single-chip mode and targets body control modules, gateway ECUs, and multiplexed vehicle networks.
For engineers reviewing the MC9S12DG256MPVE datasheet, MC9S12DG256MPVE pinout, MC9S12DG256MPVE application, or MC9S12DG256MPVE equivalent, key selection criteria include its 112-pin LQFP package, dual CAN interface with software compatibility, 2.5V internal logic supply with 5V I/O tolerance, and background debug mode (BDM) support for in-circuit development.
Technical Context
The MC9S12DG256MPVE implements the CPU12 core with M68HC11 instruction set compatibility, 7-bit prescaler ECT with 8 input-capture/output-compare channels, and flexible peripheral routing-including CAN0/CAN4 pins shared with J1850/IIC and software-selectable SPI/PWM mappings. Its SIM module integrates clock generation (PLL-based), interrupt control, and multiplexed external bus interface (MEBI).
It supports both 16-bit wide and 8-bit narrow external bus modes, enabling cost-optimized memory interfacing. The device includes a 0.5–16MHz crystal oscillator, limp-home mode on clock failure, and 22 wake-up capable I/O lines (Port H, P, J, IRQ, XIRQ) for low-power STOP/WAIT operation in automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S12DT256MPVE | Same 256KB Flash, 12KB RAM, but adds third CAN module and J1850 BDLC interface | Required where SAE J1850 VPW communication (e.g., GM legacy diagnostics) is mandatory | Select MC9S12DT256MPVE only if J1850 support is needed; otherwise MC9S12DG256MPVE offers lower cost and identical core/peripheral feature set |
| S912XDP512J0 | Successor HCS12X derivative with 512KB Flash, enhanced CPU (XGATE co-processor), and improved CAN timing resolution | Targeted at next-gen platforms requiring higher code density, deterministic ISR response, or CAN FD readiness | Choose S912XDP512J0 for new designs needing scalability; MC9S12DG256MPVE remains optimal for cost-sensitive, CAN 2.0-only legacy replacements |
Compared with MC9S12DT256MPVE, MC9S12DG256MPVE omits J1850 but retains identical CAN, ADC, and PWM capabilities-reducing BOM cost where J1850 is unused. Versus S912XDP512J0, it provides proven qualification and simpler toolchain support at lower gate count and power consumption for stable production programs.

FAQ
What is the maximum bus speed supported by the MC9S12DG256MPVE?
The MC9S12DG256MPVE supports a maximum bus speed of 25 MHz in single-chip mode (equivalent to 50 MHz core frequency) and 20 MHz in expanded bus modes. This is achieved via its integrated PLL circuit, which multiplies the external crystal reference (0.5–16 MHz) to generate the required system clock while maintaining stability across −40°C to +125°C.
Does the MC9S12DG256MPVE support J1850 communication?
No, the MC9S12DG256MPVE does not include the J1850 BDLC module. Per the family product brief, only DT-series variants (e.g., MC9S12DT256MPVE) integrate the SAE J1850 Variable Pulse Width interface. The "G" suffix in MC9S12DG256MPVE explicitly denotes the two-CAN, no-J1850 configuration.
How many CAN modules are implemented in the MC9S12DG256MPVE?
The MC9S12DG256MPVE implements exactly two CAN 2.0A/B software-compatible modules: CAN0 and CAN4. These are physically routed to PM0/PM1 and PJ6/PJ7 respectively, with CAN4 sharing pins with the IIC interface and configurable via software register settings.
What ADC resolution and channel count does the MC9S12DG256MPVE provide?
The MC9S12DG256MPVE integrates two 10-bit analog-to-digital converters (ATD0 and ATD1), supporting up to 16 total input channels (8 per module). Both modules support external conversion triggering, allowing synchronized sampling across multiple sensors-a critical capability for automotive chassis and powertrain sensing.
Is the MC9S12DG256MPVE pin-compatible with other MC9S12D-Family members?
Yes, all MC9S12D-Family members-including MC9S12DG256MPVE-are fully pin-compatible within the same package variant (112-pin LQFP or 80-pin QFP). This enables direct hardware reuse across memory and peripheral configurations, such as upgrading from DG256 to DT256 without PCB redesign.
