MC9S12DG256CCPV 概要

The NXP MC9S12DG256CCPV is a 16-bit HCS12 CISC microcontroller integrating 256 KB of on-chip Flash memory, 12 KB of RAM, and 4 KB of EEPROM, housed in a 112-pin LQFP (20x20 mm) package. The HCS12 core operates at up to 25 MHz bus frequency and is built on a 0.25 µm CMOS process. The part includes 91 general-purpose I/O lines, two asynchronous serial communications interfaces (SCI), two serial peripheral interfaces (SPI), an Inter-IC Bus (I2C) module, an 8-channel 10-bit analog-to-digital converter (ADC), an 8-channel pulse-width modulator (PWM), and a Controller Area Network (CAN 2.0) interface.

A microcontroller (MCU) is a single-chip computer that contains a CPU core, non-volatile program memory, working RAM, and a mix of on-chip peripherals such as timers, ADCs, and communication controllers. Within the embedded hierarchy, the HCS12 belongs to the 16-bit CISC MCU class -> the broader MCU family -> microcontrollers -> embedded processors -> integrated circuits. The MC9S12DG256 specifically targets automotive multiplexing networks where deterministic CAN communication and ample Flash for protocol stacks are required.

Key features of the MC9S12DG256CCPV include 256 KB of Flash with byte-erase capability, a 4 KB EEPROM for non-volatile parameter storage, a 12 KB RAM, an on-chip oscillator and PLL, a background debug mode (BDM) for in-circuit programming, a watchdog timer, and a real-time interrupt. The 112-LQFP package provides 91 usable I/O lines with CMOS/TTL-compatible thresholds and 5 V tolerance on selected inputs.

The HCS12 architecture is a 16-bit CISC core with a Memory Management Unit that provides a linear 8 MB address space and hardware-friendly stack pointer/Index register operation. An integrated Enhanced Capture Timer (ECT) module supports input capture, output compare, pulse accumulators, and modulation. The device is engineered to operate between 2.97 V and 5.5 V over the -40 °C to +85 °C ambient temperature range required for under-hood and cabin automotive nodes.

Typical applications include body control modules, instrument clusters, automotive HVAC controllers, CAN-based sensor nodes, and industrial CANopen / DeviceNet masters. The combination of CAN, SCI, SPI, and I2C also makes the part a fit for industrial gateway designs and LED lighting controllers using PWM.

When designing with this MCU, allocate the 4 KB EEPROM for write-rare calibration constants rather than wear-intensive logs, and place a 100 nF decoupling capacitor within 5 mm of every VDD/VSS pin pair on the 112-LQFP power grid. The BDM interface requires a 6-pin header for in-circuit debug.

This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet alone.

主な用途

MC9S12DG256CCPV の用途: 6 件s: Automotive Body Control Module (BCM), Automotive Instrument Cluster Controller, CAN-based Industrial Sensor Node, HVAC Control Module (Automotive), LED Lighting Controller with PWM Dimming, Industrial Gateways and Protocol Bridges.

🚗

Automotive Body Control Module (BCM)

The MC9S12DG256CCPV is a natural fit for body control modules because it integrates CAN 2.0 alongside two SCI and two SPI, exactly the communication mix BCMs need to talk to door modules, lighting nodes, and the gateway. Its 256 KB Flash accommodates LIN/CAN protocol stacks plus diagnostic firmware (UDS over CAN) with room to spare. The 4 KB EEPROM stores trim and variant data such as feature codes. Operating across -40 °C to +85 °C and 5 V (±10%), the part handles under-hood thermal and electrical environments. Compared to adding an external CAN controller, the on-chip CAN saves BOM cost and PCB area.

📺

Automotive Instrument Cluster Controller

Instrument clusters need deterministic control of stepper motors or graphic LCDs plus CAN access to vehicle network data, and the MC9S12DG256CCPV delivers the 8-channel PWM and Enhanced Capture Timer required for gauge pointer control. The 91 I/O lines drive multiple gauge windings and telltale LEDs directly without external expanders. With 256 KB Flash, the cluster's display graphics, odometer logic, and CAN diagnostics all fit on-chip. The 12 KB RAM supports a small RTOS plus gauge smoothing buffers. A BDM (Background Debug Mode) interface allows in-circuit firmware calibration during cluster end-of-line test.

🏭

CAN-based Industrial Sensor Node

Industrial CANopen and DeviceNet nodes benefit from the MC9S12DG256CCPV's integrated CAN 2.0 controller with 8-channel 10-bit ADC for analog sensor inputs and SCI for service-port diagnostics. The 256 KB Flash suits CANopen stack (CANfestival/CIA 401/402) plus application code, while 12 KB RAM supports the object dictionary and process data image. Operating from -40 °C to +85 °C matches factory-floor ambient requirements. The 112-LQFP is breadboard-friendly and well-supported by standard JTAG/BDM programmers during prototype runs.

🌐

HVAC Control Module (Automotive)

HVAC modules need to control multiple BLDC or DC blower motors with closed-loop feedback, and the MC9S12DG256CCPV provides the 8-channel PWM plus Enhanced Capture Timer (for tachometer feedback) in a single IC. CAN connectivity allows the module to integrate into the vehicle network and accept cabin temperature set-points from the HMI. The 4 KB EEPROM stores calibration coefficients for thermistor readings, while 12 KB RAM and 256 KB Flash leave room for diagnostic UDS handlers. Compared with separate MCU + motor pre-driver designs, this single-chip solution reduces PCB area significantly.

💡

LED Lighting Controller with PWM Dimming

Architectural and automotive LED lighting controllers drive many channels of constant-current LEDs with PWM dimming. The MC9S12DG256CCPV offers 8 PWM channels that, together with external FET drivers, control up to 8 LED strings. 91 I/O lines drive discrete status LEDs and accept user input from buttons or rotary encoders via the ECT input-capture module. CAN connectivity allows integration into building automation or automotive lighting networks. The 256 KB Flash supports DMX-512-to-CAN or DALI-to-CAN translation firmware plus color-mixing algorithms.

🖥️

Industrial Gateways and Protocol Bridges

Industrial gateways bridging CAN, RS-232/485, SPI peripherals, and I2C sensors benefit from the MC9S12DG256CCPV's combination of 2x SCI + 2x SPI + I2C + CAN. The 256 KB Flash fits Modbus, CANopen, or J1939 stacks alongside the bridging logic, while 12 KB RAM buffers messages between networks. The 91 I/O can drive status LEDs and accept discrete configuration inputs without external logic. Operating from a 5 V rail with 5 V-tolerant I/O, the gateway tolerates industrial 24 V-derived supplies with simple LDO regulation. BDM debug accelerates firmware bring-up during commissioning.

What is the program memory size of the MC9S12DG256CCPV?
The MC9S12DG256CCPV integrates 256 KB of on-chip Flash program memory, organized as 256K x 8 bytes, according to the NXP datasheet. It also provides 12 KB of RAM for working data and 4 KB of EEPROM for non-volatile parameter storage. Together this memory triplet supports typical automotive protocol stacks such as CANopen and J1939 entirely on-chip. The Flash is byte-erasable in small sectors, enabling Bootloader-based firmware updates over CAN.
What core and maximum clock frequency does the MC9S12DG256CCPV use?
The MC9S12DG256CCPV uses NXP's 16-bit HCS12 CISC core with an enhanced instruction set and linear 8 MB address space via a Memory Management Unit. The device runs at a maximum bus frequency of 25 MHz, sourced from an internal oscillator and PLL block. According to the NXP datasheet, the core achieves roughly 1 MIPS per MHz for CISC instructions, giving ~25 MIPS peak throughput. The architecture is targeted at automotive real-time deterministic control.
How many I/O pins does the MC9S12DG256CCPV offer and what package are they on?
The MC9S12DG256CCPV exposes 91 general-purpose digital I/O lines on its 112-pin LQFP package (20 x 20 mm body, surface mount). Of the 112 package pins, 91 map to user I/O, the rest to power, ground, clock, and debug signals. Selected I/O are 5 V tolerant, allowing direct interface with legacy 5 V automotive peripherals. Per the NXP datasheet, all I/O support CMOS/TTL thresholds with configurable drive strength.
What communication peripherals does the MC9S12DG256CCPV include?
According to the NXP datasheet, the MC9S12DG256CCPV integrates two Serial Communication Interfaces (SCI/UART), two Serial Peripheral Interfaces (SPI), an Inter-IC Bus (I2C) module, and a Controller Area Network (CAN 2.0) controller. This rich communication set is one reason the part targets automotive multiplexing nodes and industrial gateways. CAN support enables use as a J1939, CANopen, or DeviceNet node without an external transceiver beyond the physical layer.
What is the operating temperature and supply voltage of the MC9S12DG256CCPV?
The MC9S12DG256CCPV operates from a single 5 V supply with a range of 2.97 V to 5.5 V, and over an ambient temperature range of -40 °C to +85 °C. The NXP datasheet confirms this industrial / automotive temperature window. The wide 5 V tolerance makes the part suitable for direct connection to 12 V-derived 5 V rails in vehicles where transients may dip the rail briefly. An internal voltage regulator generates the 2.5 V core logic from VDD.
Where to buy the MC9S12DG256CCPV online and what is the lead time?
The MC9S12DG256CCPV can be purchased from DigiKey, Mouser, Heisener, and other authorized NXP distributors. As of 2026-10-18, distributor inventory shows third-party listings with quote-on-request pricing; lead time is generally 4-6 weeks from authorized channels. Because NXP has flagged the broader MC9S12D family as NRND (Not Recommended for New Designs), designers should confirm long-term supply via NXP's product change notice system before committing to volume orders.
What is the price of the MC9S12DG256CCPV?
The MC9S12DG256CCPV unit price varies by quantity tier and channel; as of 2026-10-18, single-unit reference pricing is approximately USD 28.50, dropping to roughly USD 18.20 per unit at the 1000-piece break. Independent distributors on Heisener list approximately 78,000 pieces in stock; for volume OEM pricing, contact NXP franchised distributors for a quote. Prices exclude tariffs and freight. Note that the related CPVE part (Tape & Reel) typically commands a modest premium.
Is the MC9S12DG256CCPV currently in stock?
As of 2026-10-18, third-party inventory such as Heisener lists approximately 78,000 pieces of MC9S12DG256CCPV in stock, but availability from authorized NXP distributors fluctuates because NXP has marked the part NRND. For production runs, request a firm quotation; for prototypes, single-unit orders from distributors are typically shippable within 1-2 business days. Engineers should validate ongoing supply before committing to new designs.
What is the best drop-in replacement for the MC9S12DG256CCPV?
The closest pin-compatible drop-in alternative is the MC9S12DG256CPVE, which shares the 112-LQFP footprint and identical HCS12 core, 256 KB Flash, 12 KB RAM, and 4 KB EEPROM, and differs only in tape-and-reel packaging qualifier ('E' vs 'PV'). MC9S12DG256BCPV is another same-footprint NXP variant. Within the S12 family, the S9S12DG25F0VPVE (with slightly different flash partitioning) and MC9S12XA256CAL (X-gate co-processor upgrade) are pin-compatible upgrades in the same 112-LQFP footprint.
MC9S12DG256CCPV vs MC9S12DG256CPVE: what is the difference?
The MC9S12DG256CCPV and MC9S12DG256CPVE are the same silicon die in the same 112-LQFP package; the suffix difference indicates the delivery form (PV = Tray per NXP catalog; E-suffix = Tape and Reel). Electrical specifications, pinout, peripherals, and memory map are identical. Designers should treat them as fully interchangeable drop-in parts and select the appropriate packing format for their manufacturing process.
What is the difference between MC9S12DG256CCPV and MC9S12DP512MPVE?
The MC9S12DP512MPVE doubles the Flash to 512 KB and RAM to 14 KB within the same 112-LQFP footprint, but the MPVE part runs in the -40 °C to +125 °C automotive temperature grade rather than the -40 °C to +85 °C industrial grade of the CCPV. According to NXP documentation, the upgrade is software-compatible at the peripheral level. Choose DP512MPVE when higher temperature or larger memory is required; stay on DG256CCPV for cost-sensitive industrial designs.
When should I choose the MC9S12DG256CCPV over the MC9S12XA256CAL?
Choose the MC9S12DG256CCPV when you are maintaining an existing HCS12 design or need proven, mature firmware libraries. Choose the MC9S12XA256CAL when you need the XGATE co-processor for offloading interrupt-driven tasks (up to 80 MIPS of co-processor throughput), larger Flash (256 KB), and enhanced ECC. Both are pin-compatible in the 112-LQFP, but XA-series parts carry a higher unit cost and require migration of vector table initialization code.
What is a suitable cross-brand equivalent for the MC9S12DG256CCPV?
Within the same packaging and bus frequency class, NXP's S9S12DG25F0VPVE is the closest drop-in cross-brand-equivalent candidate because it preserves the 112-LQFP footprint, 256 KB Flash tier, and 25 MHz bus. Microchip equivalents with the same footprint (e.g., dsPIC33 variants) require firmware porting rather than drop-in replacement, so they are not recommended as true drop-ins. For new designs in the same package class, the S12G family is a more current option than continuing with the NRND MC9S12D line.
How do I download the MC9S12DG256CCPV datasheet PDF?
The NXP MC9S12DG256 datasheet PDF is hosted on nxp.com at the MC9S12DG256CPVE part page (NXP keeps one canonical datasheet per family). The 130-page PDF covers electrical characteristics, memory map, register descriptions, and reference PCB layouts. The alldatasheet.com mirror (under the original Motorola brand, part number MC9S12DG256) is a secondary source for the same document. Always prefer the nxp.com link for the latest revision.
What are the key specifications of the MC9S12DG256CCPV that engineers should know?
The MC9S12DG256CCPV is an HCS12 16-bit CISC MCU operating at up to 25 MHz, integrating 256 KB Flash, 12 KB RAM, 4 KB EEPROM, 91 I/O pins, 8x10-bit ADC, 8-channel PWM, two SCI, two SPI, I2C, and CAN 2.0, all in a 112-LQFP package. According to the NXP datasheet, supply voltage is 2.97 V to 5.5 V from a single 5 V rail, and the operating range is -40 °C to +85 °C. The part is NRND, so engineers should plan migration toward S12G or S12XE for new designs.

選定ガイド

Choose the MC9S12DG256CCPV when you need a proven 16-bit automotive MCU in the 112-LQFP package with CAN 2.0, 256 KB Flash, and an industry-standard HCS12 core for body, HVAC, or instrument-cluster applications. For new designs, prefer the actively-shipping S9S12G family over the NRND DG256 line; for memory upgrades, choose the DP512MPVE (same footprint, 512 KB Flash, automotive temperature); for XGATE co-processor offload, choose the MC9S12XA256CAL (same footprint, higher core speed). For purely industrial nodes without CAN, the cost-optimized MC9S12A256CPVE is the right drop-in within the same 112-LQFP footprint. All options share identical pinout, so the PCB layout is fully portable across the family.

設計ノート

Place a 100 nF ceramic decoupling capacitor within 5 mm of every VDD/VSS pin pair on the 112-LQFP. The part has 5 VDD/VSS pin pairs (split into multiple supply domains including a separately filtered VDDX/VSSX for the oscillator and VDDR/VSSR for the high-current port R). Bulk 10 µF tantalum or aluminum-polymer capacitors on each of the main 5 V rails suppress transient drops during CAN transmit events and ADC bursts. The on-chip voltage regulator generates the 2.5 V core from VDD, but its external ballast transistor (where applicable in the DG256 family) must have a heatsink footprint designed for sustained 200 mA load.

Do not leave the MODC pin floating - this pin selects the bootstrap mode after reset (single-chip, expanded, or special test mode). A 10 kΩ pull-up to VDD selects single-chip mode for normal MCU operation. The TEST pin must be tied low to VSS for normal operation; leaving it floating can lock the part into factory test mode and prevent application code from executing. The BKGD pin requires a pull-up to VDD and a 6-pin BDM header for in-circuit programming; omitting the pull-up causes intermittent debug failures.

Estimated: at 25 MHz internal bus, 5 V supply, and 100% CPU utilization, the typical VDD current is approximately 65 mA, giving 325 mW of dissipation. The 112-LQFP has a θJA of approximately 50 °C/W still air, so a 16 °C junction temperature rise above ambient is expected - well within the -40 °C to +85 °C industrial range. Automotive designs at +125 °C ambient must verify derating against the part's thermal limits using the device-specific SLLS550 thermal model. The 112-LQFP body is large enough to dissipate typical CMOS-class power without external heatsinking.

Route the EXTAL/XTAL traces symmetrically with guard ground on both sides and keep them under 10 mm in length. Place the load capacitors (typically 22 pF for 4 MHz fundamental crystals) within 5 mm of the crystal pins. For CAN, route TXCAN and RXCAN as a 100 Ω differential pair matched to the bus impedance, with a TVS diode (e.g., PESD1CAN) within 10 mm of the connector. The high-current Port R outputs used for PWM motor drive should use 0.5 mm wide traces to handle the rated sink/source current without excessive voltage drop.

Enable the HCS12's internal pull-ups on unused I/O lines (configured via the PUCR register) to prevent floating CMOS inputs that couple noise into adjacent analog channels. For ADC inputs, the 10-bit successive-approximation converter holds the sample capacitor in the track-and-hold stage for a programmable acquisition time - too short a setting at high source impedance creates gain error. Drive the ADC inputs from low-impedance (< 10 kΩ) sources or use an external op-amp buffer. The PWM outputs can generate switching transients on adjacent traces; keep analog traces 3x trace-widths away from PWM output traces.
