MC908EY16VFAE Descripción general
An HC08 microcontroller is an 8-bit embedded-processing device within the broader microcontroller and semiconductor hierarchy. HC08 devices combine a CPU core, Flash memory, RAM, timers, serial interfaces, and I/O resources on one integrated circuit. They are commonly used for appliance controls, automotive subsystems, industrial equipment, and small motor-control systems where deterministic control and compact integration matter more than high computational bandwidth.
The MC908EY16VFAE provides 16 KB of Flash program memory, 512 x 8 RAM, 24 I/O pins, and connectivity identified in the source data as LINbus, SCI, and SPI. The 8 MHz operating speed supports embedded control loops and communication tasks, while the internal oscillator avoids requiring a separate external timing source for basic operation. Its integrated POR and PWM peripherals support reliable startup behavior and proportional control functions.
The device uses a 32-LQFP 7 x 7 mm package and is offered in tray packaging according to the supplied component data. Electrical details such as operating voltage, temperature range, flash endurance, ADC specifications, timer resolution, and exact pin functions were not provided in the verified excerpts, so those values should be confirmed from the manufacturer datasheet before design release.
Typical applications include automotive body and comfort modules, appliance control boards, small industrial controllers, sensor interfaces, and embedded serial bridges. The 24 I/O pins provide external connections for sensors, actuators, indicators, and communication transceivers. LINbus support is particularly relevant to distributed vehicle networks, while SCI and SPI can connect to display modules, sensors, storage devices, or other controllers.
A key design consideration is obsolete-part risk. The supplied PDF search result identifies the part as obsolete, while distributor listings remain available for procurement. Designs should therefore verify source authenticity, package markings, lifecycle status, and firmware compatibility before production use. For a new design, engineers should also assess whether a current MCU family provides a longer supply commitment and a more complete development toolchain.
This page combines verified distributor specifications, procurement context, package information, application guidance, and replacement cautions. It distinguishes confirmed MC908EY16VFAE attributes from parameters that still require manufacturer-datasheet confirmation, helping engineers make a more reliable legacy-design decision.

Aplicaciones típicas
MC908EY16VFAE es adecuado para 6 aplicacións: Legacy Automotive Body-Control Module, Appliance Control Board, Industrial Sensor Interface, Small Motor and PWM Control, Serial Communication Bridge, Embedded Service Equipment Controller.
Legacy Automotive Body-Control Module
The MC908EY16VFAE fits a legacy body-control design requiring 24 I/O lines, 8 MHz embedded processing, 16 KB Flash, and serial connectivity including LINbus, SCI, and SPI. It could coordinate switches, lamps, sensors, actuators, and diagnostic interfaces where the HC08 application is already validated. Its internal oscillator simplifies the clock arrangement, while POR and PWM support dependable startup and proportional output functions. The critical tradeoff is lifecycle risk: the supplied PDF result calls the MCU obsolete, so new vehicle programs should verify qualification, temperature limits, sourcing, and long-term supply before design freeze.
Recomendado
Appliance Control Board
The MC908EY16VFAE is appropriate for a compact appliance controller when the design already targets HC08 firmware and needs 24 I/O points for switches, sensors, displays, relays, and actuators. Its 16 KB Flash accommodates embedded application code, while 512 bytes of RAM and an 8 MHz core support typical supervisory control tasks. SCI can serve a local console or external module, SPI can connect to a display or storage device, and PWM is useful for motor or heating-control functions. Because the exact voltage and pin map are not present in the supplied excerpts, engineers must validate them against the original design before release.
Recomendado
Industrial Sensor Interface
The MC908EY16VFAE can serve as the local controller for an industrial sensor interface containing discrete inputs, status indicators, and serial upstream communication. Its 24 I/O pins provide connections for sensors and control signals, and the 8 MHz HC08 core is sufficient for deterministic polling and state-machine tasks. SCI offers a straightforward path to a supervisory controller, while SPI can support compatible sensors or external transceivers. Because long-term industrial availability and electrical limits are not fully documented in the verified excerpts, the MCU is best selected for maintenance of an existing platform rather than an unqualified new production design.
Recomendado
Small Motor and PWM Control
The MC908EY16VFAE is suited to a small embedded actuator controller that uses PWM for motor, valve, or illumination functions and needs a compact set of digital controls. Its verified 8 MHz speed supports deterministic control-loop execution, while POR provides a defined startup path and PWM reduces the need for separate timing hardware. The 16 KB Flash and 512-byte RAM fit modest supervisory firmware, and SCI can support configuration or diagnostics. Engineers must confirm timer width, PWM resolution, supply voltage, and pin multiplexing from the full datasheet because these values are not included in the supplied search excerpts.
Recomendado
Serial Communication Bridge
The MC908EY16VFAE can bridge SCI or SPI-connected subsystems when a compact protocol converter or embedded gateway is required. Its three verified connectivity options—LINbus, SCI, and SPI—allow the controller to interface with vehicle networks, human-readable diagnostics, and short-distance peripheral devices. The 24 I/O pins add status, control, and interrupt paths, while 16 KB Flash provides room for protocol handlers and configuration data. Firmware reuse can reduce redesign effort, but packet timing, buffer capacity, baud-rate support, and electrical levels are not provided here and must be established from the official documentation.
Recomendado
Embedded Service Equipment Controller
The MCU can support a legacy service-equipment controller that combines front-panel inputs, status indicators, actuators, and a serial host connection. Its 24 I/O pins reduce the need for external logic, and the 8 MHz HC08 processor can execute test sequences and fault-state handling. SCI can connect to a host computer or test fixture, while PWM and discrete outputs can control indicators or low-power actuators. For production equipment, however, obsolete lifecycle status creates maintenance exposure. The design should retain known-good stock, document programming procedures and firmware images, and qualify a current MCU migration before expanding the equipment fleet.

Notas de diseño
Do not approve a substitute from memory capacity or package appearance alone. The verified excerpts do not provide a complete MC908EY16VFAE pinout, voltage range, timer map, or peripheral timing details. Before using any similarly named HC08 or S12 device, compare every power, ground, reset, oscillator, communication, and I/O signal against the manufacturer datasheet and confirm boot, debug, and firmware compatibility.
Inventory and lifecycle planning are critical because the device is identified as obsolete. Freeze the exact MPN, record authorized-source traceability, retain tested spare units, and obtain written stock and lot information. Estimated: one unit is priced at $7.2292 as of 2026-10-21, so maintaining a strategic spare pool should be weighed against the risk of an unplanned redesign; no future price or supply guarantee should be assumed.
For an existing 32-LQFP board, preserve the 7 x 7 mm land pattern and do not alter pin assignments without checking the official package drawing. Review exposed-pad, thermal, and soldering requirements using the complete manufacturer documentation; those details are absent from the supplied excerpts. PCB rework should also account for legacy-part marking, lead finish, moisture handling, and possible availability from multiple authorized channels.
Información de cumplimiento
The verified excerpts do not provide environmental or automotive-qualification declarations. Obtain the exact manufacturer or authorized-distributor compliance record before release.
