MC9S08DN32ACLH - 40MHz 8-Bit MCU with CAN | NXP
MPN： MC9S08DN32ACLH ✗ 停產MC9S08DN32ACLH 概覽
A microcontroller is a programmable integrated circuit that combines a CPU core, memory, peripherals, and input/output interfaces on one semiconductor device. The S08 belongs to the 8-bit MCU hierarchy, where an integrated controller executes embedded software, reads sensors, controls actuators, and manages communications. Its CAN and LIN connectivity place it within vehicle-network and industrial embedded-control systems.
The MC9S08DN32ACLH provides 32 KB of flash, 1 KB of RAM, a 16-channel, 12-bit ADC, and a 40 MHz HCS08 CPU operating from a 20 MHz bus. These resources support real-time control, data acquisition, vehicle communication, and embedded protocol handling. The package is a 64-lead LQFP measuring 10 x 10 mm.
The product belongs to the MC9S08DN32 automotive and industrial microcontroller family. Its integrated communications and mixed-signal peripherals make it suitable for body modules, sensor nodes, actuators, automotive gateways, and industrial controllers. The 8-bit architecture is appropriate where deterministic control and network connectivity matter more than high-end processor performance or large memory capacity.
Typical embedded designs must provide the correct supply voltage, decoupling, clock configuration, reset behavior, and communication termination. CAN and LIN networks also require suitable transceivers, wiring, and bus protection; the microcontroller does not replace those external interface components. Firmware, memory-map details, electrical limits, and package dimensions should be verified against the manufacturer datasheet.
This page combines verified distributor specifications, lifecycle information, sourcing data, and engineering-oriented application guidance. It also clearly distinguishes verified facts from parameters requiring manufacturer confirmation, helping engineers evaluate the MC9S08DN32ACLH without relying on an assumed pinout, unsupported replacement, or fabricated electrical value.

典型應用
MC9S08DN32ACLH 適用於 6 應用s: Automotive Body Control Node, CAN Network Gateway, LIN Sub-Gateway, Industrial Sensor and Actuator Controller, Motor and Relay Control Module, Analog Data Acquisition Module.
Automotive Body Control Node
The MC9S08DN32ACLH fits a body-control or distributed vehicle node because the verified device combines CAN and LIN connectivity with a 40 MHz 8-bit HCS08 CPU and 32 KB flash. The MCU can manage digital inputs, actuator commands, diagnostic logic, and network tasks in a compact embedded design. Its 64-LQFP 10 x 10 mm package supports conventional surface-mount assembly, while the 16-channel, 12-bit ADC supports selected analog monitoring functions. The design still requires the correct CAN or LIN transceiver, protection components, vehicle power regulation, and exact NXP pin definitions. Firmware scheduling, bus timing, reset behavior, and EMC requirements must be validated against the target vehicle platform and the current manufacturer documentation.
推薦
CAN Network Gateway
Use the MC9S08DN32ACLH for a low-to-moderate complexity CAN gateway or network supervisory node when the gateway must combine protocol handling with local control. The 40 MHz HCS08 CPU provides processing headroom for message routing and service logic, while 32 KB flash supports application code and 1 KB RAM supports working state. CAN connectivity is explicitly identified in the verified product data. The MCU does not provide the physical CAN transceiver, so the board must include a suitable transceiver, bus protection, termination strategy, and reference-clock implementation. Validate message timing, filter configuration, fault handling, and network sleep behavior against the exact NXP datasheet and the vehicle or industrial network specification.
推薦
LIN Sub-Gateway
The MC9S08DN32ACLH is suitable for a LIN-connected sub-gateway or local sensor controller because LIN functionality and an 8-bit HCS08 CPU are verified features. The controller can evaluate inputs, format diagnostic information, and coordinate commands between a higher-level network and local LIN nodes. Its 16-channel, 12-bit ADC is useful when analog sensing is required, although the exact sampling, reference, and trigger behavior must be checked in the datasheet. A LIN network requires an external physical-layer transceiver, connector protection, and appropriate bus capacitance. Keep firmware timing compatible with the LIN protocol, test wake-up and sleep transitions, and validate all pin multiplexing before committing the PCB layout.
推薦
Industrial Sensor and Actuator Controller
The MC9S08DN32ACLH can serve as a compact industrial sensor and actuator controller when the system needs deterministic 8-bit processing and mixed peripheral support. The 40 MHz CPU supports responsive control loops, the 16-channel 12-bit ADC can acquire multiple analog channels, and 32 KB flash provides room for embedded application logic. CAN or LIN can connect the controller to a distributed machine network. Because the supplied data does not state the operating voltage, temperature range, or AEC-Q100 status, industrial equipment should not assume those ratings without checking the official NXP documentation. External signal conditioning, power conversion, isolation, protection, and bus transceivers remain system-level requirements.
推薦
Motor and Relay Control Module
The MC9S08DN32ACLH can be evaluated for small motor, relay, and discrete actuator-control modules where real-time logic and network communication are more important than a high-bit-width processor. The 40 MHz HCS08 CPU supports fast peripheral servicing, while the 32 KB flash and 1 KB RAM support control tables, state machines, diagnostics, and communication services. The MCU’s CAN or LIN interface can expose status and commands to a larger vehicle or machine network. Power transistors, drivers, flyback protection, current sensing, and safety interlocks must be designed outside the MCU and checked for the exact load. The part’s NRND status requires lifecycle review for new long-life programs.
推薦
Analog Data Acquisition Module
The MC9S08DN32ACLH can be used as the control element in an analog data-acquisition module because its verified feature set includes a 16-channel, 12-bit ADC and a 40 MHz 8-bit CPU. The MCU can sequence channels, process measurements, apply calibration, and transmit results over CAN or LIN. The ADC’s stated 2.5 us conversion time should be incorporated into the sampling plan, while the exact input range, reference voltage, acquisition time, and accuracy must be confirmed from the manufacturer datasheet. Front-end signal conditioning, protection, filtering, grounding, and calibration storage are system-level tasks. Use the 64-LQFP package only after checking its pin assignments and thermal requirements.

設計說明
Start the layout from the exact NXP MC9S08DN32ACLH pinout and 64-LQFP package drawing rather than a generic LQFP footprint. Confirm every supply, ground, clock, reset, programming, and communication connection against the current datasheet. Place required decoupling and support components close to their associated pins, and preserve the manufacturer’s recommended land pattern and exposed-connection requirements before releasing artwork.
The retrieved data confirms 32 KB flash, 1 KB RAM, and a 40 MHz HCS08 CPU but does not provide the operating-voltage range or absolute maximum ratings. Treat those values as [DATA_NEEDED: operating voltage range] and verify them in the official datasheet. Do not select the external regulator, decoupling, or protection network from assumptions; first establish the exact rail tolerances, startup requirements, and reset behavior.
Do not substitute a similarly named S08DN or S08DZ device without checking the pinout, memory map, peripheral set, clocking, communication features, electrical limits, and qualification. The verified data does not establish MC9S08DN32MLF or S9S08DZ32F2CLH as drop-in replacements. Because MC9S08DN32ACLH is NRND, record the exact ordering code, datasheet revision, firmware assumptions, and lifecycle plan for production traceability.
合規資訊
The verified search results mention automotive and industrial positioning but do not provide explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 statements for this exact ordering code. Confirm current declarations and qualification documents with NXP.
