MC908EY16AMFJE Übersicht
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, on-chip program memory (Flash/ROM), data memory (RAM), and a set of integrated peripherals. The HC08 family from NXP/Freescale is a CISC 8-bit architecture succeeding the HC05/HC11 lines, sitting within the broader hierarchy of microcontroller -> embedded processor -> semiconductor. HC08 EY-series parts specifically target cost-sensitive, low-pin-count motor and lighting control with PWM-rich timer blocks.
Key features include 16 KB Flash program memory, 512 B RAM, an on-chip Serial Peripheral Interface (SPI), an internal clock generator (ICG) that removes the need for an external crystal in many designs, and two 16-bit 2-channel timer modules (TIMA and TIMB) that provide multiple PWM channels for motor/lighting regulation. A 5 V single supply and automotive-grade part numbering make it a drop-in choice for body and chassis ECUs originally designed around the HC08E family.
The device uses a CISC instruction set with a 16 KB linear program space and byte-addressable RAM. The internal clock generator module eliminates one external component by deriving the 8 MHz bus clock from an internal reference; the SPI block supports master/slave operation for sensor or EEPROM expansion.
Typical applications include automotive body controllers, HVAC actuators, lighting controllers, simple BLDC/PMSM motor drivers via TIMA/TIMB PWM, sensor conditioning front-ends, and industrial white-goods control boards replacing legacy HC05/HC11 designs. The 32-LQFP footprint remains compatible across the wider MC908E/GR family, easing board reuse.
When designing with this part, ensure the 5 V rail is regulated to within HC08 tolerance and that the SPI bus is properly terminated when more than one slave is attached; the internal clock generator module accuracy (typically +/- 5%) may require external timing reference for CAN or LIN master applications.
This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and design considerations not typically consolidated on stock pages, helping engineers shorten cross-reference research for legacy HC08-based designs.

Typische Anwendungen
MC908EY16AMFJE ist geeignet für 6 Anwendungs: Automotive Body Control Module, HVAC Blower Motor Control, LED Lighting Controller, Sensor Conditioning Front-End, Industrial Appliance Control (White Goods), LINbus Slave Node.
Automotive Body Control Module
The MC908EY16AMFJE is well-suited for distributed automotive body controllers thanks to its 5 V single supply, 16 KB Flash for storing lighting/door/seat logic, and LINbus support for in-vehicle networking. The TIMA/TIMB 16-bit timers generate PWMs that drive LED brightness ramp curves and motor actuators, while the integrated LVD/POR protects against crank-voltage dropouts. Compared with discrete logic, the HC08 part reduces BOM and PCB area in 32-LQFP and is software-compatible with the wider HC08 family for code reuse across body-domain ECUs.
Empfohlen
HVAC Blower Motor Control
The HC08EY16's two 16-bit 2-channel timers (TIMA and TIMB) provide PWM outputs ideal for closed-loop control of DC blower motors in HVAC systems. With 8 MHz bus frequency, the timers deliver sufficient resolution for soft-start ramps and PID loops; 512 bytes of RAM are adequate for state machines and lookup tables. Operating from 5 V, the part tolerates the noisy blower-motor environment when paired with decoupling capacitors, while LVD/POR ensures clean motor restart after battery transients.
Empfohlen
LED Lighting Controller
The MC908EY16AMFJE drives multi-channel LED lighting via PWM from TIMA and TIMB, with Flash enabling daylight-sensor calibration tables. Its 8-bit core executes state-machine logic for adaptive headlamps or interior lighting at low power, while 16 KB Flash supports DRL/turn-signal sequencing. The SPI bus simplifies connections to LED-driver ICs and EEPROM-trimmable current sources, and the 32-LQFP (7x7 mm) footprint minimizes PCB area in compact lamp modules.
Empfohlen
Sensor Conditioning Front-End
When bridging analog sensors (temperature, pressure, position) into a vehicle network, the MC908EY16AMFJE excels due to its SCI/SPI interfaces for ADC and transducer ICs, plus LINbus for backhaul to a body controller. The HC08's 8-bit ALU and 512 B RAM hold linearization tables and average filters; PWM outputs can be repurposed as digital dimming or watchdog-pulse channels. The 32-LQFP form factor supports slim sensor-housing designs.
Empfohlen
Industrial Appliance Control (White Goods)
Legacy washing machines, dishwashers, and induction cooktops benefit from the HC08EY16's robust 5 V supply tolerance and high-noise immunity typical of automotive-grade parts. TIMA/TIMB generate PWMs for triac-fired heater control and inverter stages, while the internal clock generator removes an external crystal and reduces BOM cost. The 32-LQFP-32 (7x7 mm) footprint drops onto universal main-control PCBs reused across product lines.
Empfohlen
LINbus Slave Node
The MC908EY16AMFJE is widely deployed as a LINbus slave for seat-control switches, mirror motors, and roof-modules, where its integrated SCI block implements the LIN protocol layer with minimal software overhead. 8 MHz bus clock provides ample headroom for LIN 2.x message scheduling, while 16 KB Flash stores application firmware and 512 B RAM holds frames and signal flags. Compact 32-LQFP footprint fits inside space-constrained door-modules.

Wichtigste Unterscheidungsmerkmale
- Internal clock generator (ICG) eliminates external crystal in many designs (vs. MC908JL16CPE)
- Higher Flash-to-pin ratio in same LQFP-32 footprint (vs. S9S08DZ60ACLH)
- Two 16-bit 2-channel timers give 4 PWM outputs from a single MCU (vs. MC908JL16CPE)
Designhinweise
The MC908EY16AMFJE requires a regulated 5 V supply; typical VDD tolerance is +/- 10% per the HC08EY16 datasheet. Place a 100 nF decoupling capacitor as close as possible to each VDD pin (pin 9 and pin 32) plus a bulk 10 uF tantalum or ceramic at the regulator output. The internal POR holds the core in reset until VDD crosses the safe threshold - allow at least 10 ms of stable 5 V before code execution begins for proper Flash initialization.
Estimated: at 8 MHz, the HC08 core dissipates roughly 30-50 mW from 5 V supply, well within the LQFP-32 thermal envelope of approximately theta_JA 65 C/W. In sealed automotive under-hood modules, ensure ambient does not exceed 85 C without derating; the part typically derates to about 5 mA/MHz additional supply current at high temperature. For very compact enclosures, add a small copper pour under the exposed die attach pad (if present on the specific die revision) or 1 cm square of 2 oz copper to spread heat.
The 32-LQFP (7x7 mm, 0.8 mm pitch) requires careful trace routing - keep digital signal traces short and route the OSC1/OSC2 traces symmetrically with ground guard rings to minimize clock jitter. Route SPI lines (SPSCK, MOSI, MISO, SS) as matched-length or impedance-controlled when bus speed exceeds 1 MHz. Place the ICG-related capacitors within 5 mm of pins 29-30 to prevent parasitic oscillations.
Do not assume the internal clock generator is accurate enough for CAN or LIN master timing - the ICG tolerance is typically +/- 5%, so external crystal or ceramic resonator is required for those roles. Do not apply voltage to any pin before VDD ramps - this can latch the device. When programming Flash in-circuit, isolate the RESET line and ensure no watchdog resets interfere with the load routine. Always consult the latest silicon errata for any mask-set-specific anomalies.
Compliance-Informationen
RoHS, REACH, AEC-Q100 and lead-free status not present in the verified distributor data for this automotive-grade HC08 part. The 'AUTO 908EY16A MOS9' descriptor on Mouser suggests AEC-Q100 qualification, but this could not be confirmed against the datasheet in the provided web data - further sourced verification recommended.
