MC908QY1AMDWE Übersicht
A microcontroller is an integrated circuit that executes embedded control software from nonvolatile program memory and coordinates digital inputs, outputs, timers and communication interfaces. The MC908QY1AMDWE belongs to the M68HC08 family, whose enhanced CPU08 core uses a CISC architecture and Von Neumann organization. This places it in the MCU branch of embedded semiconductors, where software compatibility, memory size and peripheral integration matter more than the processing capacity associated with application processors.
The part combines 1.5 KB of flash with 14 I/O ports in a compact 16-pin surface-mount package. Its 8 MHz CPU frequency is suitable for compact embedded control tasks that do not require high-bandwidth computation. The DWE package suffix is represented in verified marketplace data as a 16-SOIC offering, while additional secondary data also describes a 0.65 mm-pitch TSSOP-16 variant; the exact mechanical drawing must be checked before footprint approval.
Typical HC08Q roles include simple keypad and display controllers, low-speed serial-interface nodes, small industrial controllers and cost-sensitive products that need flash programmability. Because the MCU is an older M68HC08 design, engineering review should confirm current software-tool support, programmer availability, errata status and the NXP lifecycle position before committing a new design.
PCB implementation should reserve all 16 pins and verify the manufacturer symbol against the ordered package. Decoupling, programming-test-point access, oscillator components and unused-pin treatment must follow the applicable hardware manual. Firmware replacement also requires CPU, memory-map and peripheral compatibility; a similar package alone does not prove that a candidate is a drop-in substitute.
This page consolidates verified distributor specifications, lifecycle information, sourcing data and engineering cautions. It distinguishes explicitly reported values from unresolved details so procurement and design teams can evaluate the MC908QY1AMDWE without assuming unverified electrical, timing or mechanical parameters.

Typische Anwendungen
MC908QY1AMDWE ist geeignet für 6 Anwendungs: Legacy HC08Q Control Module, Compact Automotive Interface Controller, Keypad and Human-Interface Controller, Low-Speed Serial Interface Node, Small Industrial Sequence Controller, Cost-Sensitive Service Controller.
Legacy HC08Q Control Module
The MC908QY1AMDWE fits a legacy embedded-control module whose firmware already targets the 8-bit CPU08 architecture and Von Neumann memory organization. Its 8 MHz maximum clock and 1.5 KB flash are appropriate for supervisory logic, state machines and small I/O-control tasks. Maintaining the exact MCU avoids an unnecessary code and board redesign, although the end-of-life designation makes long-term availability and qualification a concern.
Empfohlen
Compact Automotive Interface Controller
The MC908QY1AMDWE can support a small legacy vehicle interface when the design requires its 14 I/O ports, 8 MHz processing capability and verified automotive-grade listing. It is best positioned for supervisory logic, actuator sequencing or signal conditioning rather than safety-critical computation. Before installation, confirm the exact temperature limits, AEC-Q100 status and any automotive qualification record because those details are absent from the supplied sources.
Empfohlen
Keypad and Human-Interface Controller
With 14 I/O ports and 1.5 KB of flash, the MC908QY1AMDWE is suited to compact keypad scanning, LED indication, debouncing and simple menu logic. The 8 MHz CPU08 provides enough control bandwidth for modest polling loops while preserving code compatibility with qualified HC08Q firmware. Designers should verify external-driver requirements and exact pin multiplexing from the device documentation rather than infer functions from the I/O count.
Empfohlen
Low-Speed Serial Interface Node
MC908QY1AMDWE is viable for a legacy serial node that performs protocol framing, command parsing and limited actuator control around an 8 MHz CPU core. Its modest 1.5 KB flash favors compact firmware rather than protocol-heavy stacks. Exact UART or serial-module capabilities are not present in the supplied data and must be confirmed in the exact DWE device documentation before the pinout is assigned.
Empfohlen
Small Industrial Sequence Controller
The MC908QY1AMDWE can execute deterministic sequencing, discrete I/O control and fault-state logic in a small industrial module when the original HC08Q firmware and hardware must be retained. Its 14 I/O ports provide a meaningful control surface for inputs, outputs and status signaling, while 8 MHz processing supports ordinary supervisory tasks. Industrial adoption must include separate assessment of temperature, EMC, isolation and lifecycle risk.
Empfohlen
Cost-Sensitive Service Controller
MC908QY1AMDWE remains useful in a service controller where exact HC08Q code compatibility is more important than processor performance or a modern software roadmap. The compact 16-pin device can manage simple sequences and status outputs with a legacy 1.5 KB code budget. Because the part is end of life, procurement should reserve traceable inventory, control substitutions and document the last-time-buy decision if the product will remain in production.

Technische Referenzdaten für MC908QY1AMDWE – Vergleich, Designhinweise und Compliance-Informationen.
Auswahlhilfe
Designhinweise
Design the supply rail only after resolving the conflicting secondary descriptions of 3.3 V/5 V operation versus the listed 4.5 V to 5.5 V range for MC908QY1AMDWE. Use the exact NXP datasheet revision and ordering information as the controlling requirement. Include local decoupling, verify startup current and avoid relying on the family-level voltage description for this grade.
Do not approve the footprint from marketplace package labels alone. One verified listing calls the device 16-SOIC, while another describes TSSOP-16 at 0.65 mm pitch under the DWE code. Download the official DWE package drawing, compare lead width, pitch and body dimensions, and test-fit the actual reeled component before releasing PCB artwork.
Treat similar CPU frequency or the HC08 name as insufficient evidence for substitution. A safe replacement must preserve the 16-pin DWE footprint, CPU08 execution behavior, memory organization, peripheral registers, programming method and temperature requirements. The supplied cross-reference results do not establish a true drop-in replacement, so changes require schematic, PCB and firmware review.
Compliance-Informationen
The supplied sources identify an automotive temperature grade but do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free or conflict-minerals declarations.
