MC9S08DV48ACLH - 40MHz 48KB Flash 8-Bit MCU | NXP
MPN： MC9S08DV48ACLH ✗ 停產MC9S08DV48ACLH 概覽
A microcontroller, or MCU, is a semiconductor device that integrates a processor core, program memory, data memory, peripherals, and interface pins into one package. Within the embedded-control hierarchy, this device belongs to the 8-bit MCU, HCS08 core, embedded-control IC, and semiconductor categories. Its combination of flash memory, serial networking, analog conversion, timers, and on-chip emulation makes it suitable for compact automotive and industrial controllers rather than general-purpose computing systems.
Key features reported for the MC9S08DV48ACLH include a 40 MHz processor clock, a 20 MHz bus, a 48 KB Flash program memory, 2 KB RAM, embedded CAN and LIN support, and a 16-channel 12-bit ADC. The S08 instruction set supports up to 32 interrupt and reset sources. These interfaces allow one controller to manage communication and real-time peripherals while reducing the number of discrete components on a board.
The part belongs to the HCS08/S08DV family and uses an 8-bit data bus. The NXP overview lists the MC9S08DV48ACLH as NRND, meaning it is not recommended for new designs. Existing designs can still require procurement and lifecycle planning, while new projects should compare currently active MCU options before committing to a PCB or software platform.
Typical embedded uses include automotive body and climate-control modules, industrial interface controllers, CAN or LIN gateway equipment, and compact instrumentation products. The 64-LQFP package exposes more peripheral and communication pins than smaller packages, making it practical for systems that need broader external connectivity while retaining through-hole-like board assembly.
The principal design consideration is lifecycle risk. Because the device is marked NRND, engineers should verify stock, long-term supply, and firmware support through authorized distributors. PCB replacement should also compare pin mapping, clock configuration, memory map, peripheral multiplexing, and software driver assumptions rather than relying only on the device name.
This page combines verified NXP and distributor listings, available pricing signals, lifecycle information, and practical selection guidance. It also distinguishes confirmed drop-in alternatives from unsupported replacements, helping engineers make sourcing decisions without assuming that a similar MCU is electrically and mechanically interchangeable.

典型應用
MC9S08DV48ACLH 適用於 6 應用s: Automotive Body Control Module, CAN and LIN Network Gateway, Industrial Sensor Interface, USB-Enabled Embedded Instrument, Motor and Timing Control, HMI and Instrumentation Controller.
Automotive Body Control Module
The MC9S08DV48ACLH fits a compact body-control or vehicle interface module because its S08DV platform combines a 40 MHz 8-bit CPU with 48 KB Flash, 2 KB RAM, CAN, and LIN connectivity. The 16-channel 12-bit ADC can support analog sensing, while the 64-LQFP package provides access to communication and peripheral pins. A vehicle design must still verify the exact transceiver, pin multiplexing, automotive qualification, and operating-temperature requirements before release.
推薦
CAN and LIN Network Gateway
The MC9S08DV48ACLH is a logical candidate for a small network gateway because the verified listings identify both CAN and LIN master support alongside USB 2.0. Its 48 KB Flash can hold protocol and application firmware, while 2 KB RAM supports buffering and state management for an 8-bit embedded controller. The design should budget external transceivers, validate bus timing, and confirm that the chosen suffix exposes every required communication pin on the 64-LQFP footprint.
推薦
Industrial Sensor Interface
For an industrial sensor interface, the MC9S08DV48ACLH provides a useful combination of 16-channel, 12-bit ADC capability and a 40 MHz control core. The ADC can digitize multiple analog inputs while the MCU handles thresholding, filtering, diagnostics, and communication. The 2 KB RAM limit means the software should avoid buffering large sample sets in internal memory; use external memory or streaming methods when needed. The industrial temperature and compliance requirements are not present in the supplied verified data and must be checked separately.
推薦
USB-Enabled Embedded Instrument
The MC9S08DV48ACLH can support a compact embedded instrument that needs local control and USB connectivity rather than a high-performance processor. Its 48 KB Flash supports embedded firmware, and the 8-bit S08 core is suitable for supervisory logic, calibration, status reporting, and peripheral control. USB implementation still requires exact pin assignment, clock configuration, transceiver or internal PHY details, and firmware support from the authoritative manufacturer documentation.
推薦
Motor and Timing Control
The MC9S08DV48ACLH is suitable for a small motor or timing controller where deterministic control, analog feedback, and serial diagnostics are needed. The enhanced 16-bit timers are relevant for period measurement, pulse generation, and timing tasks, while the ADC can monitor feedback signals. Actual motor-drive suitability depends on the exact S08DV timer and pin configuration, which are not fully included in the supplied search data. Validate timing, interrupt latency, and external driver requirements before design release.
推薦
HMI and Instrumentation Controller
The MC9S08DV48ACLH can act as a low-cost controller for a compact human-machine interface or measurement front end. The MCU handles button and status logic, sequences the 16-channel 12-bit ADC, stores configuration in Flash, and reports data through CAN, LIN, or USB. Its 64-LQFP package provides more external pin access than a small-outline package, while the 8-bit architecture is appropriate for supervisory rather than graphics-intensive workloads.

設計說明
Power planning should begin with the exact supply pins and operating limits in the NXP datasheet; the verified data identifies 3.3 V / 5 V support but does not provide complete current limits, regulator requirements, or pin-level decoupling values. Place required bulk and bypass capacitors at the device power pins according to the manufacturer layout guidance, and verify sequencing for USB, CAN, and LIN transceiver supplies.
Because the device is specified in a 64-LQFP package and supports multiple communications, preserve pin multiplexing and routing flexibility during schematic capture. Confirm every pin name and alternate function in the authoritative datasheet before routing. Keep sensitive ADC inputs away from switching nodes and communication edges, and provide clean grounding for the analog and digital sections.
Do not substitute a similarly named S08 part based only on the MPN prefix. The target is NRND, and the verified comparison pages do not prove that each candidate has identical memory, peripherals, pinout, qualification, or software behavior. For a drop-in decision, compare land pattern, pin names, alternate functions, electrical limits, clocking, memory map, interrupt vectors, and driver support.
Estimated thermal analysis requires the actual supply voltage, core current, ambient temperature, and package thermal resistance; none of the complete operating-current or thermal-resistance values are supplied here. Do not assume the 40 MHz rating applies continuously to every peripheral. Measure or calculate worst-case dissipation from the final duty cycle and use the manufacturer package data to size copper and airflow.
The reported $5.2926 starting price and Heisener stock figure are point-in-time signals as of 2026-10-21, not a guaranteed allocation or lifecycle commitment. For production purchasing, obtain authorized-channel confirmation, batch traceability, date-code information, and a written supply-risk assessment because the NXP page marks the part NRND.
合規資訊
The supplied verified data identifies automotive and industrial market positioning but does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for this exact MPN. Obtain current declarations from NXP or an authorized distributor.
