MC9S08DZ48AMLH - 8-Bit 40MHz 48KB Automotive MCU | NXP
NXP Semiconductors MC9S08DZ48AMLH is an automotive 8-bit S08DZ microcontroller with a 40 MHz CPU, 48 KB of flash memory, CAN connectivity, and a 64-LQFP package measuring 10 x 10 mm. The verified product listing identifies 3 KB of RAM, LIN-master capability, EEPROM, a 24-channel 12-bit ADC, and support for up to 32 interrupt or reset sources. It is positioned for vehicle-network control and powertrain applications.
A microcontroller is an embedded semiconductor that integrates a processor core, program memory, data memory, peripherals, and communication interfaces on one package. In the automotive electronics hierarchy, the MC9S08DZ48AMLH belongs to the S08DZ family of 8-bit MCUs, combining a deterministic control core with CAN and LIN connectivity, analog measurement, timers, and embedded debug support. This integration allows vehicle modules to acquire sensor data, evaluate control logic, and communicate with other electronic control units.
Key verified features include an enhanced HCS08 core operating at 40 MHz with a 20 MHz bus, 48 KB of flash, 3 KB of RAM, an automotive temperature grade, and a 64-pin low-profile QFP package. The HC08 instruction set includes the BGND instruction, while the 12-bit ADC provides 24 channels and a stated 2.5-second conversion figure in the retrieved specification snippet. These interfaces support body, powertrain, and vehicle-network designs where compact embedded control is required.
The S08 architecture is suited to real-time control rather than high-bandwidth computing. Its peripheral set combines communication and local control, reducing the need for separate logic devices around the MCU. CAN connectivity supports vehicle-network communication, LIN-master capability supports lower-cost automotive networking, and the ADC supports analog sensor acquisition. The 40 MHz core provides additional processing headroom for protocol handling, diagnostics, and control algorithms within a qualified operating environment.
Typical uses include automotive body-control modules, motor or actuator controllers, powertrain interface modules, CAN gateways, LIN nodes, and sensor-conditioning controllers. The 10 x 10 mm LQFP package also makes the device suitable for multilayer automotive electronic-control-unit boards where analog, digital, and network functions must coexist. Board-level validation remains essential because EMC, transient protection, grounding, and automotive qualification depend on the complete design.
A key design consideration is that software, pin multiplexing, clock configuration, transceiver selection, and memory programming must be validated against the manufacturer documentation for the exact ordering code. Do not treat a generic S08DZ pinout as sufficient when assigning CAN, LIN, ADC, timer, debug, or power functions. Likewise, validate thermal performance, voltage limits, and external protection networks during system qualification.
This page consolidates verified manufacturer and distributor information, identifies the unavailable engineering data without guessing, and distinguishes the device from unverified substitutes. It is intended to support component identification, sourcing, initial architecture selection, and comparison work while directing final design decisions to official NXP documentation and qualified validation records.
