MC68908GZ16VFJE Descripción general
What is an 8-bit microcontroller? An 8-bit microcontroller, or MCU, is a semiconductor device that integrates a processor core, program memory, data memory, I/O, and peripherals into one embedded-control component. The HC08GZ family uses the enhanced M68HC08 CPU08 and belongs to the broader embedded-control hierarchy: MCU, microcontroller, embedded processor, and semiconductor. Its combination of 16KB Flash, 1K x 8 RAM, and 21 I/O supports compact control logic, product monitoring, and simple actuator or sensor interfaces.
Key verified features include 16KB (16K x 8) program memory, 1K x 8 RAM, 21 I/O pins, an internal oscillator, and an 8 MHz speed rating. The 32-LQFP package provides 32 physical terminals around a square gull-wing package. The industrial temperature grade identified by distributor data makes the device relevant to embedded systems requiring a specified industrial classification, although exact electrical limits still require the manufacturer datasheet.
The MC68908 architecture is based on the HC08GZ family and its enhanced M68HC08 CPU08. Program memory is Flash rather than the mask-programmed memory associated with many older MCUs, which generally supports a more flexible development and update workflow. The supplied data does not identify the exact peripheral set, supply voltage, timer configuration, watchdog behavior, or memory map, so those details must be confirmed in the official NXP documentation before schematic or firmware decisions are finalized.
Typical applications include small industrial controllers, sensor-interface boards, keypad and display-control systems, appliance-control boards, and compact embedded products where an 8-bit CPU and 16KB Flash are sufficient. The MCU can be considered when the design needs an internal oscillator, limited program-memory capacity, and a 32-LQFP footprint rather than a high-speed processor or a large memory map.
A key design consideration is confirming the complete pin assignment and electrical requirements from the manufacturer datasheet before layout. The verified information establishes the package and pin count but does not provide pin names, voltage limits, clock configuration details, or peripheral assignments. Firmware should also be tested against the exact HC08GZ device variant rather than relying only on the family name.
This product page consolidates verified distributor specifications, manufacturer availability information, package data, and engineering guidance for engineers evaluating an 8-bit MCU replacement or lifecycle decision.

Aplicaciones típicas
MC68908GZ16VFJE es adecuado para 6 aplicacións: Compact Industrial Controller, Sensor Interface Board, Appliance Control, Keypad and Display Control, Small Motor and Relay Control, Embedded Product Controller.
Compact Industrial Controller
The MC68908GZ16VFJE fits compact industrial-control tasks where an 8-bit MCU, 16KB Flash, and 1K x 8 RAM are sufficient for supervisory logic, mode control, and I/O coordination. Its verified 8MHz speed rating provides a defined performance class, while the 21 I/O count can support sensors, discrete inputs, indicators, and actuator-control signals. The 32-LQFP package is useful when a low-pin-count surface-mount design is preferred. However, the supplied data does not specify timers, communication peripherals, supply limits, or exact pin assignments, so the final controller design must be checked against the official NXP datasheet and validated for industrial environmental requirements.
Recomendado
Sensor Interface Board
The MC68908GZ16VFJE can serve as the local controller for a small sensor-interface board that gathers digital inputs and manages indicator or alarm outputs. Its 21 I/O pins provide a useful interface count for discrete sensors, switches, and status signals without requiring a larger package, and the internal oscillator simplifies designs that do not need an external clock source. The 16KB Flash capacity is appropriate for small acquisition and decision routines. Designers should still verify analog and digital pin multiplexing, electrical limits, and any required serial interface because those details are not included in the verified search data.
Recomendado
Appliance Control
The MC68908GZ16VFJE is appropriate for appliance-control boards that coordinate user inputs, relays, indicators, and simple timing functions. Its 16KB Flash and 1K x 8 RAM can support a compact state machine, while the 8MHz speed rating is relevant to deterministic control-loop tasks. The 32-LQFP footprint enables a relatively compact assembly and avoids through-hole insertion in automated production. For an appliance design, the engineer should confirm the exact operating voltage, reset requirements, oscillator behavior, watchdog availability, and pin multiplexing from the manufacturer documentation before finalizing the schematic.
Recomendado
Keypad and Display Control
The MC68908GZ16VFJE can coordinate keypad scanning, display updates, and simple menu logic in a compact embedded user interface. Twenty-one I/O pins may be allocated among keypad lines, display-control signals, status indicators, and control outputs, while the 16KB Flash footprint can hold focused firmware for scanning and state management. The internal oscillator is useful for a self-contained control board. Because the verified data does not define LCD, keypad, timer, or communication peripherals, the selected MCU should be checked for the required peripheral functions and timing behavior before being assigned to this design.
Recomendado
Small Motor and Relay Control
The MC68908GZ16VFJE can be evaluated for small relay, solenoid, or motor-control subsystems where the firmware primarily manages command sequencing, interlocks, feedback inputs, and fault states. The 8MHz speed rating and 21 I/O pins provide a reasonable basis for low-complexity control logic, while 16KB Flash can hold a compact supervisory routine. The MCU itself is not a power driver, so external transistors, protection networks, and appropriate power components are required. Verify pin drive capability, timing, supply behavior, and thermal requirements in the official datasheet before using it in a new power-control board.
Recomendado
Embedded Product Controller
The MC68908GZ16VFJE is suitable for a compact embedded product controller when the application needs an 8-bit CPU, limited Flash, modest RAM, and a moderate number of I/O signals. Its 32-LQFP package helps reduce board footprint, and the internal oscillator supports a simpler clocking arrangement than a design requiring an external source. The device can serve as the central state machine for a product with discrete inputs, outputs, and modest timing requirements. Before production, confirm all electrical and peripheral specifications from NXP, especially because the supplied evidence establishes the architecture and package but not the complete peripheral feature list.

Notas de diseño
The verified package is 32-LQFP (7x7 mm) with gull-wing terminals. Before routing, obtain the official NXP land pattern and pin table; the search data confirms the package family and terminal count but does not provide individual pin functions. Check pin 1 orientation, exposed-pad requirements if any, and the recommended solder-mask and paste geometry against the manufacturer drawing. Do not derive the footprint from the package name alone.
Supply-voltage limits, absolute maximums, and power-consumption figures are not included in the verified data, so do not assume a nominal rail or current budget. Determine the operating range from the NXP datasheet, then size the regulator and decoupling network for the actual MCU and connected loads. For an end-of-life design, preserve the original power architecture where possible because changing the supply domain can affect firmware, I/O thresholds, and board-level EMC behavior.
A same-package or related-family MPN is not automatically a drop-in replacement. Verify pin-by-pin assignment, reset behavior, oscillator connections, memory map, peripheral multiplexing, electrical thresholds, and software programming model before substituting an HC08-family device. The target has a verified 16KB Flash and 1K x 8 RAM configuration, but the alternative cross-reference search did not provide those parameters for the listed candidates. Treat all unverified alternatives as engineering leads, not approved replacements.
The supplied data identifies an industrial temperature grade but does not provide the numeric junction or ambient operating range, thermal resistance, or power dissipation. Estimate thermal performance only after obtaining the electrical limits and calculating actual switching and I/O activity. For low-duty-cycle embedded control designs, package dissipation may be modest, but sustained high activity or an elevated ambient environment requires a documented thermal margin and PCB copper assessment.
Información de cumplimiento
The verified search results identify industrial temperature grade and an end-of-life overview but do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields remain unknown.
