Product details
Overview
MC9S12DP256BMPV from NXP (formerly Freescale/Motorola) is a 16-bit HCS12 microcontroller featuring 256 KB on-chip Flash EEPROM, 12 KB RAM, and integrated CAN 2.0B controller. It operates at up to 25 MHz bus speed with PLL clock multiplication, supports 10-bit ATD converters (two 16-channel modules), and delivers real-time control in automotive powertrain and chassis systems.
For engineers reviewing the MC9S12DP256BMPV datasheet, MC9S12DP256BMPV pinout, MC9S12DP256BMPV application, or MC9S12DP256BMPV equivalent, this page provides verified technical context, package-specific pin mapping, functional alternatives, and supply-chain-ready availability details for industrial and automotive embedded design validation.
Technical Context
The MC9S12DP256BMPV implements the HCS12 CPU core with 16-bit data path, 24-bit address space, and background debug interface (BDM). Its CRG block supports crystal, external clock, or self-clock modes with programmable PLL multiplier (SYNR/REFDV registers) enabling stable bus frequencies from 1–25 MHz.
It integrates dual 16-channel 10-bit ATD converters with external trigger capability, four enhanced capture timers (ECT), eight PWM channels, two SCI interfaces, one SPI, one I²C, and a full MSCAN 2.0B module with 15 message buffers - all operating under single-voltage 5 V supply with internal voltage regulator support.

Pinout & Package
MC9S12DP256BMPV is packaged in an 112-pin LQFP (lead-free, RoHS-compliant, case no. 987) with 0.4 mm pitch and exposed thermal pad. Pin assignments follow Figure 2-1 of the Device User Guide (9S12DP256BDGV2/D V02.14).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EXTAL / XTAL | Oscillator input/output | Connects to external crystal (4–8 MHz) or clock source; enables precision timing for PLL and system clock generation |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU registers, disables peripherals, and forces boot vector fetch from $FFFE–$FFFF |
| BKGD / TAGHI / MODC | Background debug / mode control | Enables single-wire BDM communication; determines boot mode (normal vs. special test configurations) |
| VREGEN | Voltage regulator enable | High-active signal enabling internal 5 V regulator output; required for operation when external VDD not supplied to VDDR |

Key Features
| Feature | Design Value |
|---|---|
| On-chip Flash programming | Supports in-system programming via BDM without external HV supply; enables field firmware updates |
| Dual ATD with external triggers | ATD0 and ATD1 accept independent ETRIG0/ETRIG1 signals for synchronized sampling across sensors or subsystems |

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 |
|---|---|---|---|
| MC9S12DG256CPVE | Same HCS12 core and 256 KB Flash, but lacks MSCAN; uses 80-pin QFP package (vs. 112-pin LQFP) | No native CAN 2.0B support; requires external CAN controller for networked applications | Select when CAN is not required and board space constraints favor smaller footprint |
| S912XDP512J0VLH | Enhanced XGATE co-processor, 512 KB Flash, 32 KB RAM; pin-compatible 112-LQFP but higher voltage (3.3 V I/O) | Higher performance and memory capacity; incompatible with 5 V peripheral interfaces without level-shifting | Select for next-generation designs requiring increased code space and parallel processing offload |
Compared with MC9S12DG256CPVE, MC9S12DP256BMPV provides integrated CAN 2.0B and larger I/O count; versus S912XDP512J0VLH, it offers 5 V compatibility and proven qualification for legacy automotive platforms without XGATE dependency.

FAQ
What is the maximum bus frequency supported by the MC9S12DP256BMPV?
The MC9S12DP256BMPV supports a maximum bus frequency of 25 MHz when using the PLL with appropriate SYNR/REFDV settings. This is achieved with an external 8 MHz crystal and PLL multiplication factor of 3.125× (e.g., REF=2, SYNR=5). The device also supports self-clock mode at 1–5.5 MHz for reduced EMI or low-power operation. All timing specifications in the Electrical Characteristics section assume operation within this validated range.
Does the MC9S12DP256BMPV include an internal voltage regulator?
Yes, the MC9S12DP256BMPV includes an internal voltage regulator controlled by the VREGEN pin. When VREGEN is asserted high, the regulator supplies regulated 5 V to the core logic (VDDR rail). This eliminates the need for an external 5 V regulator in many designs, provided VDDX (I/O supply) is present. The regulator's load capacitance requirement is specified as 10 µF ceramic per the Device User Guide Section A.4.
How many CAN controllers does the MC9S12DP256BMPV integrate?
The MC9S12DP256BMPV integrates one MSCAN 2.0B controller with full protocol compliance, supporting both standard and extended frame formats. It features 15 message buffers, hardware ID filtering, and automatic retransmission. While some derivative devices like MC9S12DJ256 include dual CAN, the MC9S12DP256BMPV provides exactly one CAN module - confirmed in Table 0-1 Derivative Differences and Section 18 of the Device User Guide.
What package type is used for the MC9S12DP256BMPV?
The MC9S12DP256BMPV is exclusively offered in the 112-pin LQFP package (case number 987), as documented in Appendix B of the Device User Guide. This package includes an exposed thermal pad for improved heat dissipation and is lead-free/RoHS compliant. The 80-pin QFP variant applies only to derivatives such as MC9S12DG256 and is not valid for the MC9S12DP256BMPV.
Can the MC9S12DP256BMPV operate from a single 5 V supply?
Yes, the MC9S12DP256BMPV can operate from a single 5 V supply applied to VDDX, with VREGEN enabled to power the internal regulator for VDDR. However, separate analog (VDDA), core (VDD1/VDD2), and PLL (VDDPLL) supplies must still be decoupled appropriately. The minimum VDDPLL voltage is 2.35 V, and all supply rails require low-ESR ceramic capacitors per Section A.1.2 and Figure 20-1 layout guidelines.
