MC908GT16CBE 概要
A microcontroller is a compact embedded-computing device that integrates a CPU, program memory, data memory, I/O, timers, and communication peripherals on one semiconductor package. The HC08 MCU family provides a straightforward 8-bit architecture for products that do not require the processing power or memory capacity of a 32-bit embedded controller. MC908GT16CBE is positioned for general-purpose control, monitoring, and simple user-interface functions.
Verified listings identify 16 KB of Flash program memory, 512 x 8 RAM, 36 I/O pins, an 8 MHz operating speed, and a 42-pin SPDIP package. The device is supplied in tube packaging according to the retrieved part data. Its through-hole package is useful for prototypes, industrial controllers, educational platforms, and systems assembled where leaded-package compatibility is preferred over a compact surface-mount footprint.
The HC08 platform is described in the retrieved data as a low-cost, high-performance member of the M68HC08 family. Its 8-bit CPU08 architecture is suitable for sequential control logic, keypad and display interfaces, sensor acquisition, actuator control, and low-to-moderate-rate communication tasks. Exact peripheral availability, supply voltage limits, timer resources, and electrical operating conditions are not included in the provided verified data and should be confirmed in the manufacturer documentation before schematic release.
Typical design uses include small industrial equipment, consumer products, educational controllers, and legacy embedded systems requiring an 8-bit HC08 architecture. Because the exact pin functions and peripheral map are not supplied here, PCB and firmware work should use the official MC908GT16CBE datasheet or an authorized technical document rather than relying only on distributor summaries.
The main engineering trade-off is the 16 KB Flash limit combined with an 8 MHz 8-bit core. This is appropriate for compact control logic, but firmware growth, protocol stacks, and modern connectivity may exceed its memory budget. Confirm toolchain availability, interrupt requirements, timing, and board-level pin compatibility before committing to a new design.
This product summary consolidates the verified distributor specifications, sourcing information, package constraints, and selection considerations. It also distinguishes confirmed facts from missing electrical details so engineers can make an informed sourcing and design decision.

主な用途
MC908GT16CBE の用途: 6 件s: Industrial Control Panels, Consumer Appliance Control, Educational Microcontroller Trainer, Sensor and Switch Interface Hub, Legacy Embedded System Maintenance, Small Motor and Actuator Sequencer.
Industrial Control Panels
The MC908GT16CBE fits compact industrial control-panel logic where an 8-bit HC08 controller must read switches or sensors and drive relays, indicators, or actuators. Its verified 8 MHz clock provides a defined processing target, while 16 KB Flash can hold the control program and 36 I/O pins support multiple external signals. The 42-pin SPDIP package also suits through-hole assembly and repairable legacy boards. Before release, verify the exact pin map, electrical limits, and peripheral assignments from the official documentation; the supplied data does not confirm timer channels, port directions, or communication blocks.
おすすめ
Consumer Appliance Control
For a simple appliance controller, the MC908GT16CBE can coordinate user inputs, operating modes, indicators, and low-complexity actuator sequences. The 16 KB Flash capacity is appropriate when firmware remains modest, and the 8-bit CPU08 core is aligned with embedded sequencing rather than intensive computation. Its 42-pin through-hole package can simplify repair and prototype assembly compared with a fine-pitch surface-mount MCU. Firmware partitioning, watchdog behavior, reset timing, and exact I/O ratings must be checked in the exact suffix documentation because they are not present in the verified search snippets.
おすすめ
Educational Microcontroller Trainer
MC908GT16CBE is suitable for an 8-bit embedded-systems trainer because the HC08 family is described in the retrieved data as low-cost and general-purpose. Students can use the 16 KB Flash program memory, 512 x 8 RAM, 36 I/O pins, and 8 MHz CPU to practice GPIO, timing, interrupts, and control sequences. The leaded 42-pin package is forgiving for breadboard and through-hole training boards. The supplied data does not identify the development toolchain or programming connector, so instructors should select those tools only after confirming the exact NXP documentation and available HC08 support.
おすすめ
Sensor and Switch Interface Hub
A sensor and switch interface hub can use the MC908GT16CBE as the central controller when it must aggregate digital inputs and drive discrete outputs. Its 36 I/O pins provide a substantial external signal budget for a through-hole implementation, and the 8 MHz clock is suitable for deterministic low-to-moderate processing tasks. The 512 x 8 RAM supports small working buffers, but the 16 KB Flash limit may constrain protocol-heavy logging or complex filtering. Confirm pin multiplexing, input thresholds, output drive limits, and any required analog front end before finalizing the schematic.
おすすめ
Legacy Embedded System Maintenance
MC908GT16CBE is appropriate for maintaining a legacy HC08-based product when the original design depends on an 8 MHz 8-bit core and a 42-pin through-hole footprint. Maintaining the original architecture can reduce firmware and board changes compared with migrating immediately to a different MCU family. The part’s 16 KB Flash and 512 x 8 RAM should be checked against the current binary size and working-memory requirements. Also verify toolchain availability, programming method, lifecycle status, and exact ordering code, because those details are not included in the supplied distributor summaries.
おすすめ
Small Motor and Actuator Sequencer
The MC908GT16CBE can serve as the sequencing controller for a small actuator system when the design uses discrete outputs, simple interlocks, and modest timing loops. The 8 MHz HC08 core provides a straightforward execution target, while the 36 I/O pins can accommodate control and status signals. A 42-pin SPDIP package supports through-hole power boards and prototypes. It is not appropriate to infer motor-drive capability from the generic MCU description: verify output current ratings, isolation, flyback protection, thermal limits, and timing requirements in the exact device documentation and power circuitry.

- 42-pin SPDIP through-hole format （vs MC908GT8CBE)
設計ノート
Start the layout from the exact official MC908GT16CBE pinout rather than the package name alone. The supplied data confirms a 42-pin SPDIP format and 36 I/O pins, but it does not identify every signal or no-connect position. Place required bypass capacitors near their documented pins, provide a low-impedance ground plane, and preserve the specified oscillator and reset routing. Because the part is leaded, verify hole pattern, pin numbering orientation, and connector spacing before releasing the PCB footprint.
The verified listing identifies a 5 V supply, but it does not provide the complete absolute maximum ratings, operating-voltage range, or current consumption. Do not infer safe capacitor voltage or input limits from the nominal 5 V description. Before power-up, obtain the exact manufacturer datasheet, verify the supply tolerance and sequencing requirements, and calculate the total rail current with margin for I/O loads and attached peripherals. Add local decoupling where the device documentation recommends it.
A related MPN or same-family controller is not automatically a drop-in replacement. Confirm package suffix, pin names, reset behavior, oscillator connections, memory map, interrupt vectors, and peripheral assignments for each candidate. The supplied comparison results mention MC908GT16CFBE, MC908GT8CBE, and MC908MR32VFUE, but they do not establish complete pin-level compatibility. Keep the original part number in the approved-vendor list until the manufacturer documentation and a hardware validation build confirm interchangeability.
The verified data does not specify which I/O functions support high-speed signaling or which pins have special analog or peripheral functions. Route external signals according to the exact pin table, keep oscillator and reset traces short, and separate potentially noisy switching-node copper from sensitive control lines. If the design connects sensors, motors, relays, or communication transceivers, include the required protection, filtering, grounding, and isolation outside the MCU footprint. Validate timing with an oscilloscope after layout.
The MCU is supplied in a 42-pin SPDIP package, so thermal behavior depends strongly on the PCB, airflow, internal dissipation, and the exact operating frequency and I/O load. The supplied data does not provide power dissipation or junction-temperature limits. Use the manufacturer’s electrical characteristics to estimate internal loss, then compare the result with the package and board thermal constraints. Avoid estimating thermal performance from the package alone, especially in a sealed industrial enclosure.
コンプライアンス情報
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. No compliance claim should be inferred from the distributor listings.
