MC908AP16CFBE - HC08 8-Bit MCU 16KB Flash 8MHz 44-QFP | NXP
MPN： MC908AP16CFBE ⚠ 最後購買機會MC908AP16CFBE 概覽
A microcontroller (MCU) is a single-chip computer containing a processor core, program and data memory, peripherals, and I/O. Within the embedded-systems hierarchy, an MCU is a type of integrated circuit (semiconductor -> IC -> microcontroller). The 8-bit MCU category traditionally trades peak performance for low cost, deterministic interrupt behavior, and ultra-low static power dissipation, making it suitable for cost-sensitive industrial, appliance, and automotive body applications where higher-bit parts are unnecessary.
Key features of the MC908AP16CFBE include its 8MHz CPU clock, 16KB Flash program memory, 32 GPIO pins, multi-protocol serial communication (SCI, IRSCI, I²C, SPI), and a 10-bit ADC. The HC08APxA series represents the high-speed oscillator version of the HC08APx family, providing an external crystal/oscillator option for time-sensitive designs. The 44-QFP package is a plastic quad flat pack measuring 10x10mm with gull-wing leads suited for reflow soldering and moderate-density PCB designs.
Technically, the CPU08 core uses an enhanced HC05 instruction set with new instructions for improved code density, stack pointer paging for high-level language support, and a 16-bit index register. Memory mapping is linear with 16KB of Flash accessible to the CPU and direct page addressing for fast variable access, while the peripheral modules are mapped into the upper address space.
Typical applications include industrial control systems, appliance motor control, automotive body electronics, security and alarm panels, HVAC controllers, and remote-keyless entry receivers. The wide operating voltage (3.3V/5V) and rich peripheral set make this MCU particularly attractive for replacing legacy HC05 designs with code-compatible enhancements.
When designing with this part, verify the exact ADC channel count and timer configuration against the latest NXP datasheet revision before committing to layout. The 44-QFP footprint requires careful land-pattern design and reflow profile control for production yields.

典型應用
MC908AP16CFBE 適用於 6 應用s: Industrial Control Systems, Appliance Motor Control, Security and Alarm Panels, HVAC Temperature Controllers, Remote Keyless Entry (RKE) Receivers, Consumer Electronics Controllers.
Industrial Control Systems
The MC908AP16CFBE's 16KB Flash, 8MHz CPU08 core, and dual 3.3V/5V supply tolerance suit industrial PLCs, sensor interfaces, and factory automation modules. Its 32 GPIO and 10-bit ADC handle multiple analog sensor inputs (temperature, pressure, flow) plus digital I/O for relays and indicators. The on-chip PWM, LVD, and POR peripherals reduce external component count, while SCI/SPI/I²C enable comms with industrial HMI displays and upstream controllers. Robust QFP package and wide operating voltage simplify integration into 24V-derived rails.
推薦
Appliance Motor Control
The MC908AP16CFBE is well-matched to appliance motor control in washing machines, dishwashers, and small HVAC fans. The PWM modules drive TRIAC or MOSFET gate signals for variable-speed universal and BLDC motors, while the 10-bit ADC samples back-EMF and current-sense feedback for closed-loop control. The 16KB Flash accommodates state-machine and lookup-table code for motor commutation. Industrial-grade QFP package withstands the thermal cycling and vibration of appliance environments.
推薦
Security and Alarm Panels
The MC908AP16CFBE's low-power HC08 core and rich serial peripherals suit security alarm panels and access-control systems. SCI/SPI interfaces drive keypads, RFID readers, and GSM/PSTN modems; the 32 GPIO scan multiple zone inputs and drive siren/relay outputs. Flash memory stores configuration and event logs; LVD/POR protect against brown-out during backup-battery switchover. Dual-voltage operation simplifies interface to legacy 5V sensors and modern 3.3V wireless modules.
推薦
HVAC Temperature Controllers
The MC908AP16CFBE handles HVAC thermostat and zone-controller duties with its 10-bit ADC reading thermistor or RTD temperature sensors, PWM outputs driving damper/stepper valves, and I²C interface to CO2/humidity sensors. The 16KB Flash supports scheduling logic and adaptive-control algorithms. Wide 3.3V-5V supply tolerance simplifies direct connection to 24VAC-derived DC rails after rectification, and the industrial QFP package survives long-term thermal stress behind wall plates.
推薦
Remote Keyless Entry (RKE) Receivers
The MC908AP16CFBE is suited for fixed-location RKE receivers in automotive aftermarket and gate-opener applications. Its IRSCI/SPI interfaces connect to 315/433MHz RF receiver ICs and rolling-code decoders, while GPIO drives relay outputs for door/lock actuators. The 8MHz CPU decodes Manchester or PWM-encoded keyfob transmissions in real time. Note: this part is not AEC-Q100 qualified - for OEM automotive use, migrate to S12 automotive MCUs.
推薦
Consumer Electronics Controllers
The MC908AP16CFBE serves as a cost-effective main controller in consumer devices such as coffee makers, microwaves, washing-machine HMIs, and small home appliances. Its dual 3.3V/5V supply, 32 GPIO for key/LED matrix scanning, and PWM for buzzer or LED dimming provide the full feature set in a single chip. The 16KB Flash holds product firmware plus factory calibration data; SCI enables firmware updates via UART bootloader for field serviceability.

主要差異化特點
- Dual 3.3V/5V supply operation (對比MC908AP8CFBE)

- High-speed oscillator variant (對比MC908AP16ACFBE)
設計說明
Decouple VDD/VSS pairs (multiple pins on this QFP) with 100nF ceramic capacitors placed within 5mm of each supply pin, plus a bulk 10uF tantalum or aluminum on the main rail. Place the 100nF caps on the same layer as the IC with short, wide traces to the pins. For noisy industrial environments, add a ferrite bead in series with the supply. Enable the on-chip POR and LVD modules in software to ensure predictable startup at low VDD.
Route the 44-QFP land pattern with 0.8mm pitch - minimum trace width 0.15mm with 0.15mm clearance. Place all 4 VDD pins (5, 37, 43) and VSS pins (6, 38, 44) on internal power planes stitched with multiple vias. Avoid running high-speed digital signals under the package; keep the QFP footprint area free of vias to prevent solder joint defects during reflow. Follow JEDEC J-STD-020 MSL handling for the surface-mount package.
Do not assume 16KB Flash is fully available for application code - the bootloader, interrupt vectors, and Flash security/lock bytes consume 1-3KB. Verify Flash endurance (typically 10K cycles) and retention (10 years) against your firmware update strategy. The RST pin is bidirectional - an external reset supervisor IC is recommended if the system experiences slow VDD rise times. Always check NXP errata documents for the specific mask set revision before finalizing firmware.
