MC908AP16CFAE - 8-Bit, 16KB Flash MCU, 48-LQFP | NXP
MPN： MC908AP16CFAE ✗ 停產MC908AP16CFAE 概覽
The MC908AP16CFAE belongs to the M68HC08 family of 8-bit microcontroller units. An MCU integrates a processor core, program memory, data memory, peripheral interfaces, timers, and analog conversion functions on one semiconductor device. This integration allows a compact embedded system to sense inputs, execute control logic, and communicate with external equipment without a separate processor, memory, and interface controller.
Verified sources describe the part with 16KB flash, a 16-channel ADC, and SCI/SPI interfaces. The NXP family information also identifies it as part of the low-cost, high-performance M68HC08 family. Its 8-bit architecture and 8 MHz operating speed are appropriate for supervisory, measurement, and control tasks where deterministic peripheral handling is more important than high processor throughput. The supplied sources do not specify RAM size, ADC resolution, pin names, operating-temperature limits, or detailed timing values.
The MC908AP16CFAE is listed as End of Life by the NXP product page. Engineers should therefore treat it as a legacy procurement item, not a new-design baseline. NXP search results also reference a discontinuance and replacement overview, but the supplied data does not identify a specific manufacturer-approved drop-in replacement. Pin-compatible alternatives must be validated against the original datasheet, package drawing, memory map, interrupt system, and peripheral electrical limits before substitution.
Typical uses include industrial control panels, automotive accessory controllers, sensor-conditioning equipment, motor or actuator management, and low-cost embedded products using SCI or SPI communications. The 48-LQFP package provides a relatively high pin count for legacy control designs, while the ADC supports analog input acquisition. Because detailed memory and pin data are absent from the verified excerpts, the complete pinout and application-specific support network should be checked against the original Freescale/NXP datasheet before layout or firmware reuse.
This page consolidates verified distributor listings, lifecycle information, product identifiers, and the available cross-reference context. It does not invent missing electrical specifications or claim that an unreviewed competitor is pin-compatible. For procurement, compare current authorized inventory and ask NXP for the official product-change or replacement documentation.

典型應用
MC908AP16CFAE 適用於 6 應用s: Industrial Sensor Conditioning, Automotive Accessory Controller, Motor and Actuator Control, Remote Communication Terminal, Cost-Sensitive Consumer Appliance, Data Acquisition Module.
Industrial Sensor Conditioning
The MC908AP16CFAE fits legacy industrial sensor-conditioning products that need an 8-bit controller, 16KB flash, and a 16-channel ADC. Its listed 10-bit ADC capability can be used to sample analog sensors when the required accuracy and conversion timing are within the device limits. The 8 MHz HC08 core is appropriate for supervisory control, threshold decisions, calibration tables, and status logic rather than high-throughput signal processing. SCI or SPI can connect the controller to a sensor board, remote terminal, or data logger. Because the verified excerpts do not provide the complete ADC timing, pinout, or temperature data, the original datasheet must be checked before selecting input filtering, reference voltage, and sampling timing.
推薦
Automotive Accessory Controller
The MC908AP16CFAE can be evaluated for cost-sensitive automotive accessory control functions where the original product architecture already uses the HC08 family. The 16-channel ADC supports analog monitoring, while the listed 8 MHz core can coordinate switches, indicators, and communication routines. Its 48-LQFP package provides more external connections than a small leaded MCU, which is useful when several discrete inputs and outputs are required. However, the supplied data does not confirm AEC-Q100 qualification, automotive temperature limits, transient immunity, or functional-safety suitability. Treat it as an existing-platform component until NXP documentation and system-level validation establish the required automotive grade.
推薦
Motor and Actuator Control
The MC908AP16CFAE is suited to small legacy motor or actuator controllers when the system relies on an 8-bit MCU and modest firmware size. The 16-channel ADC can monitor current, position, temperature, or analog feedback, while the listed SCI and SPI interfaces can connect to sensors, drivers, or a supervisory controller. The 8 MHz operating speed is suitable for deterministic supervisory loops when the control algorithm is modest. Hardware design must still verify motor-drive levels, isolation, protection, timing, and thermal margins; those parameters are not provided in the verified excerpts. Use the package pinout and application guidance from the original manufacturer documentation before adding external drivers.
推薦
Remote Communication Terminal
The listed SCI and SPI interfaces make the MC908AP16CFAE relevant to compact remote terminals, simple serial controllers, and communication bridges. A legacy HC08 system can use SCI for a host or service connection and SPI for an external transceiver, display, or storage device. The 16KB flash footprint is adequate for compact control firmware, provided the application fits the device’s complete memory map and boot requirements. Before designing a new board, verify baud-rate support, interface multiplexing, electrical levels, oscillator requirements, and package pin assignments in the original datasheet. The supplied excerpts do not confirm modern USB, Ethernet, or high-speed wireless interfaces, so those functions require external components.
推薦
Cost-Sensitive Consumer Appliance
The MC908AP16CFAE may fit an existing cost-sensitive appliance controller where a small 8-bit MCU controls user inputs, relays, indicators, and simple analog measurements. Its listed 16KB flash and 8 MHz clock are appropriate for firmware that coordinates sensors and switches rather than runs a graphical interface or complex communications stack. The 48-LQFP package can simplify access to multiple I/O signals compared with a smaller package, but it requires careful escape routing and adequate board area. Verify operating temperature, ESD tolerance, supply tolerances, ADC accuracy, and lifecycle availability before production release. Because the part is End of Life, a second-source or redesign plan should be established early.
推薦
Data Acquisition Module
The 16-channel ADC and listed 10-bit converter description make the MC908AP16CFAE a candidate for compact data-acquisition modules in legacy industrial equipment. The MCU can sample multiple analog channels, apply calibration and filtering in firmware, and forward results through SCI or SPI to a higher-level controller or storage device. The 8 MHz core is suitable for modest acquisition rates and supervisory processing, but actual throughput depends on ADC conversion time, bus timing, and interrupt overhead that are not included in the verified data. Confirm input voltage limits, reference stability, sampling network requirements, and calibration storage before committing to a new measurement design.

設計說明
Do not select a replacement from the MPN family name or LQFP package alone. The verified excerpts do not establish that related MC908AP, MC908GR16, or MC908GZ16 devices share the exact pinout, memory map, ADC implementation, oscillator requirements, or peripheral timing. Obtain the original NXP/Freescale datasheets for both devices and compare every power, reset, oscillator, analog, and communication pin before modifying an existing PCB.
The supplied data identifies 3.3 V/5 V operation but does not provide absolute maximum ratings, supply tolerance, current consumption, or power dissipation. Before layout, verify the exact VDD range and I/O levels against the manufacturer datasheet. Place decoupling capacitors according to the original reference circuit, keep sensitive analog and communication returns short, and account for the tolerance of the selected 3.3 V or 5 V rail. Do not infer current limits from the family marketing description.
The MC908AP16CFAE uses a 48-LQFP (7x7) package, so a replacement PCB must match the complete land pattern, pin numbering, pad dimensions, and exposed or lead-frame geometry shown in the original package drawing. The verified excerpts do not include a complete pinout, so do not manually infer missing functions from neighboring pins. Preserve the original component height and courtyard constraints, then validate solderability and assembly process for any legacy-source device.
No verified junction-temperature, thermal-resistance, or power-dissipation data is included for this MCU. In a legacy design, calculate dissipation from the actual supply voltage and measured operating current rather than from the 8 MHz clock alone. Check the maximum ambient temperature, exposed pad or lead-frame thermal path, PCB copper area, and neighboring heat sources in the original datasheet and system thermal analysis. Treat any thermal calculation from incomplete data as provisional.
合規資訊
The supplied verified data does not provide explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 declarations. NXP search material describes the product for automotive and industrial applications, but that marketing context does not establish qualification. Verify compliance and lifecycle documentation with NXP or the authorized supplier.
