MC908GZ16MFAE Présentation
An HC08 microcontroller is a type of 8-bit microcontroller: a programmable semiconductor containing a CPU core, program memory, data memory, peripherals, and input/output interfaces for embedded control. In the hierarchy, an MCU is a microcontroller IC, while the HC08 family provides an 8-bit CPU08-based platform within the broader M68HC08 family. This class of controller is suited to appliance controls, industrial interfaces, sensor systems, and compact automation products where deterministic control and low-cost integration are more important than high compute throughput.
The principal verified specifications are the 8 MHz speed, 16 KB Flash program memory, 1 KB RAM, 37 I/O pins, and 48-LQFP package. The Flash memory provides firmware storage, while the RAM supports working data and stack operations. The 37-pin I/O count provides external digital connectivity for sensing, actuation, communication modules, and control signals. Exact supply voltage, timer configuration, communication peripherals, electrical limits, and temperature limits were not present in the supplied verified data and are identified in the validation fields where applicable.
The CPU08 architecture is an enhanced 8-bit processor platform rather than a high-performance application processor. Its role is therefore focused on embedded control: reading inputs, executing control logic, managing state, and driving outputs. The verified sources describe the device as part of the low-cost, high-performance HC08GZ family, whose members use the enhanced M68HC08 CPU08 core. This architecture should be considered when migrating firmware or selecting an alternative: software compatibility, memory-map details, peripheral availability, and electrical timing must be checked independently.
Typical application areas include small appliance controllers, industrial control panels, sensor-interface boards, keypad and display systems, motor or relay control logic, and compact embedded products requiring a 48-pin surface-mount microcontroller. The 8 MHz clock is suitable for control-loop tasks that do not require high bandwidth. The available verified data does not specify a particular peripheral list, so designers should consult the manufacturer datasheet for timer, serial-interface, analog, and interrupt details before finalizing a design.
A key engineering consideration is lifecycle planning. The NXP product page result identifies the MC908GZ16MFAE as End of Life, so new designs should confirm migration or approved sourcing requirements with NXP and authorized distributors. For an existing PCB, preserve the 48-LQFP footprint, pin assignment, supply requirements, oscillator configuration, and firmware memory expectations. Do not substitute an electrically similar MCU solely by nominal memory or clock speed; verify pin compatibility, peripheral mapping, reset behavior, and software support.
This page consolidates the verified distributor specifications, official lifecycle indication, package data, and application-oriented design guidance for engineers evaluating this obsolete 8-bit MCU. It distinguishes documented facts from parameters that still require manufacturer-datasheet confirmation, helping buyers assess supply risk and decide whether a redesign or qualified migration is more practical.

Applications typiques
MC908GZ16MFAE convient pour 6 applications: Small Appliance Controller, Industrial Control Panel, Sensor Interface Board, Keypad and Display Interface, Relay and Actuator Control, Embedded Educational Controller.
Small Appliance Controller
The MC908GZ16MFAE fits compact appliance-control boards that need deterministic 8-bit logic, digital input scanning, and direct actuator signaling. Its verified 8 MHz CPU08 core and 1 KB RAM are appropriate for supervisory control, while 16 KB Flash provides room for a focused firmware image containing state machines, debounce logic, and protection routines. The 37 I/O pins can support keys, indicators, sensors, relays, and discrete control outputs. Because the product is End of Life, an appliance maker preserving an existing design should qualify the remaining stock and confirm supply before a new production release.
Recommandé
Industrial Control Panel
For an industrial control panel, the MC908GZ16MFAE can supervise switches, indicators, interlocks, and simple sensor-conditioning interfaces when the product does not require a high-speed network or complex analog processing. The 48-LQFP package provides a compact surface-mount footprint, and the 37 verified I/O pins offer ample parallel connectivity for panel functions. Firmware would typically handle debouncing, status LEDs, sequences, and fault reporting. Industrial suitability still requires confirmation of supply voltage, temperature range, EMC performance, isolation, and regulatory requirements, none of which are established by the supplied snippets.
Recommandé
Sensor Interface Board
The MC908GZ16MFAE is suitable as a low-complexity sensor hub when the external sensors produce discrete or simple conditioned signals. Its 8 MHz CPU08 core can sample channels, apply calibration tables, filter noisy inputs, and publish results to another system. The verified 1 KB RAM and 16 KB Flash balance resource needs for small data paths, while 37 I/O pins can connect sensors, switches, and status indicators. The supplied data does not confirm ADC, comparator, or communication peripherals, so analog front-end and bus functionality must be checked in the exact datasheet before selecting this MCU.
Recommandé
Keypad and Display Interface
The MC908GZ16MFAE can serve as the controller for a keypad, status display, and discrete user-interface assembly. Its 37 I/O pins provide a practical base for scanning switches and driving display-control signals, while the CPU08 executes menu logic, debounce timers, and state updates. The 8 MHz operating speed is more than adequate for ordinary human-interface tasks and keeps the control loop responsive without requiring a high-end processor. Exact display drivers, timing, and electrical interfaces are not specified in the verified data, so external driver ICs and level requirements should be selected from the system architecture.
Recommandé
Relay and Actuator Control
The MC908GZ16MFAE can coordinate relays, solenoids, lamps, and other discrete actuators in a compact control board. The verified 8-bit core and 8 MHz clock are appropriate for sequencing, interlocks, timeout handling, and basic diagnostics, while 37 I/O pins provide connections to control outputs and feedback inputs. Engineers should add suitable driver transistors, flyback protection, isolation where required, and an appropriate power rail rather than driving loads directly from MCU pins. The supplied data does not specify output-drive current or absolute maximum ratings, so those limits must be taken from the manufacturer datasheet before hardware release.
Recommandé
Embedded Educational Controller
The MC908GZ16MFAE is a practical target for an educational or prototype embedded-control board because its architecture is explicitly positioned as a low-cost, high-performance HC08 MCU and its core resources are easy to describe. Students can use the 8 MHz CPU08 core, 16 KB Flash, and 1 KB RAM to build button-controlled outputs, timing experiments, simple data acquisition, and state-machine projects. The 48-LQFP footprint is useful for teaching surface-mount layout and pin planning. Because lifecycle status is End of Life, new educational platforms should also teach sourcing risk and migration evaluation rather than implying that long-term production availability is guaranteed.

Notes de conception
Power budgeting must start with the exact operating voltage and current limits in the MC908GZ16MFAE manufacturer datasheet; those values were not included in the supplied verified data. Do not infer safe capacitor, regulator, or I/O drive values from the 8 MHz CPU08 specification. Confirm supply sequencing, decoupling requirements, and absolute maximum ratings before layout. Estimated calculations should use actual worst-case input voltage, load current, and ambient temperature rather than the distributor snippet alone.
Preserve the verified 48-LQFP (7 x 7 mm) footprint and follow the manufacturer land pattern, pin numbering, solder-mask rules, and thermal-pad guidance. Because the supplied search snippets do not provide a complete pin table, the PCB schematic should be checked pin by pin against the exact datasheet. Keep oscillator, reset, programming, and debug-related routes short where applicable, and confirm all NC or special-function pins before fabrication. An EOL status makes footprint documentation especially important for long-lived boards.
Do not treat MC9S08GB60A, MSP430F2274, MC908GZ16CFAE, MC68908GZ8CFAE, or MC908GZ60CFAE as drop-in parts solely because search results call them equivalents. Verify package lead count, pin mapping, supply voltage, clock setup, memory organization, peripheral locations, interrupt vectors, programming algorithm, and toolchain requirements. Prototype validation should include brownout behavior, reset, oscillator startup, I/O levels, and a full firmware regression. The listed alternatives are comparison candidates until those checks pass.
For a CPU08-based control design, isolate analog or sensor inputs from switching nodes and relay-drive traces, while keeping ground-return paths compact. If the board controls relays or solenoids, route high-current paths away from the MCU and provide the protection network required by the actual load. Decoupling placement, oscillator layout, reset timing, and programming-header access should follow the manufacturer reference design when available. These recommendations are general design practices because no exact reference schematic or electrical limits were supplied.
The supplied data confirms an 8 MHz 8-bit MCU in a 48-LQFP package but does not provide power dissipation, junction temperature, package thermal resistance, or ambient-temperature limits. Estimate junction temperature only after obtaining verified supply voltage and operating current. Calculate estimated dissipation as VIN times ID minus output-load power and other rail losses, then compare the resulting junction estimate with the manufacturer limits. Do not use the presence of a 48-LQFP package alone as evidence that an external heatsink is unnecessary.
Informations de conformité
The supplied verified search results identify the product as an NXP/Freescale HC08 microcontroller but do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed from the applicable manufacturer documentation and supplier certificates.
