MC908EY16CFAE - 8-Bit 8MHz 16KB Flash MCU | NXP | 32-LQFP
MPN： MC908EY16CFAE ✗ 停產MC908EY16CFAE 概覽
An HC08 microcontroller is an 8-bit embedded-control semiconductor combining a CPU core, program memory, data memory, I/O ports, timers, interrupts, and communication peripherals on one integrated circuit. The MCU belongs to the broader hierarchy of embedded processors and microcontrollers, supporting standalone control without a separate external processor. Its 8-bit architecture is designed for cost-sensitive systems that coordinate sensors, switches, displays, and simple industrial or consumer equipment.
The verified specifications show 16 KB of program memory, 512 x 8 RAM, 24 I/O pins, 8 MHz speed, internal oscillator, and a 32-LQFP package. These values provide the basis for memory sizing, clock planning, and PCB footprint selection. The listed package is a tray-packaged 32-LQFP device according to the verified distributor data.
Typical applications include embedded keypad controllers, small motor-control systems, instrumentation interfaces, building-control nodes, and low-cost sensor-conditioning platforms. The 24 available I/O pins allow external sensors, actuators, display segments, and communication interfaces to be connected while keeping the control system compact.
A key design consideration is that the verified data does not specify the complete peripheral set, electrical operating limits, memory map, or package pin assignments. Those details must be confirmed in the manufacturer documentation before schematic capture, firmware development, or PCB layout. Search results also provide commercial availability information but do not establish a complete lifecycle classification.
This product page combines verified MPN characteristics, sourced distributor references, package information, and practical sourcing guidance. It is intended to help engineers locate MC908EY16CFAE information while clearly separating confirmed data from specifications that require datasheet confirmation.

典型應用
MC908EY16CFAE 適用於 6 應用s: Small Embedded Control Panels, Simple Sensor Monitoring, Basic Actuator and Relay Control, Instrumentation and Data Entry, Building and Environment Control, Cost-Sensitive Consumer Devices.
Small Embedded Control Panels
The MC908EY16CFAE fits compact control panels where a controller must read switches, indicators, and simple sensors while keeping the board space limited. Its verified 24 I/O pins provide a practical interface budget for keypad scanning, LEDs, and discrete input signals. The 8 MHz HC08 core and 16 KB Flash also give an application more code space than a 4 KB Flash alternative identified in the comparison results. Before schematic capture, confirm the voltage range, pin mux, timer resources, and memory map in the manufacturer documentation.
推薦
Simple Sensor Monitoring
For low-cost monitoring nodes, the MC908EY16CFAE can coordinate discrete sensor inputs, threshold logic, status indicators, and local control outputs. Its 512 x 8 RAM is suitable for small working buffers, while the 16 KB Flash capacity supports a more capable embedded application than the verified 4 KB Flash HC08 comparison part. The 8-bit architecture is appropriate when the design does not require high arithmetic throughput or large data storage. Validate analog interfaces, communication peripherals, and electrical limits before selecting it for a specific sensor node.
推薦
Basic Actuator and Relay Control
The MC908EY16CFAE can be used as the supervisory controller for relays, solenoids, indicators, and discrete actuators in a small embedded system. Its 24 I/O pins allow multiple control and sensing lines to be connected around the MCU, while the 8 MHz HC08 core supports deterministic supervisory logic when timing requirements remain modest. Because the supplied data does not specify output-driver ratings, timers, or package pin functions, the design must confirm those items in the NXP documentation and add suitable driver and protection circuitry.
推薦
Instrumentation and Data Entry
In a small instrumentation product, the MC908EY16CFAE can manage front-panel inputs, mode selection, status LEDs, and low-speed control functions. Its 16 KB Flash provides room for menu logic and acquisition routines, while 24 I/O pins can support display segments, switches, and interface signals. The 8-bit, 8 MHz architecture is best suited to supervisory and coordination tasks rather than demanding signal processing. Verify the MCU's communication peripherals and electrical specifications before assigning analog measurement or high-speed interface duties.
推薦
Building and Environment Control
The MC908EY16CFAE can serve as a compact node for building equipment, environmental monitoring, and simple load-control functions. The 24 I/O pins support distributed digital inputs and outputs, while the 16 KB Flash and 512 bytes of RAM support lightweight control logic and state variables. The internal oscillator listed in the verified data may simplify basic clock arrangements, although its accuracy and operating limits are not supplied. Confirm power-supply requirements, watchdog behavior, communications, and environmental ratings before using it as a field-installed controller.
推薦
Cost-Sensitive Consumer Devices
The MC908EY16CFAE is suitable for cost-sensitive embedded products where a compact 8-bit MCU can manage buttons, indicators, simple displays, and auxiliary control functions. The 32-LQFP 7 x 7 mm package supports space-constrained board layouts, and the 16 KB Flash capacity is more useful for application logic than the verified 4 KB Flash comparison candidate. The design should still account for startup behavior, I/O electrical limits, programming method, and production programming requirements. These details are not included in the supplied web excerpts and must be verified before production release.

主要差異化特點
- Larger verified Flash memory than the identified HC08 comparison part (對比MC68HC908GR4CFAE)
- Explicit 8 MHz operating speed specification (對比MC68HC908GR4CFAE)
- Known internal oscillator configuration (對比MC68HC908GR4CFAE)
- Verified 24-I/O integration (對比MC68HC908GR4CFAE)
設計說明
Use the verified 32-LQFP 7 x 7 mm footprint as the starting point, but obtain the NXP package drawing before routing escape traces. Confirm pin 1 orientation, exposed-pad treatment if applicable, land-pattern tolerances, solder-mask clearance, and assembly requirements. The supplied search excerpts do not include the pinout, so do not infer individual signal assignments.
Before connecting external sensors or actuators, verify the MC908EY16CFAE supply-voltage range, I/O voltage limits, input thresholds, output-drive capability, and absolute maximum ratings from the manufacturer datasheet. The verified excerpts do not provide electrical limits. Add local decoupling and suitable protection only after those values are confirmed.
Do not treat a shared 32-LQFP package as proof of drop-in compatibility. The verified comparison identifies MC68HC908GR4CFAE as having 4 KB Flash versus the target's 16 KB Flash, so firmware capacity and memory layout differ substantially. Validate pin functions, peripherals, clock requirements, programming workflow, and reset behavior before any substitution.
The supplied data does not specify operating temperature, power dissipation, thermal resistance, or maximum supply voltage. Therefore no thermal calculation should be inferred from the available data. For production design, obtain the manufacturer electrical and package specifications, estimate junction temperature from the actual operating current and board environment, and apply the resulting limits during qualification.
合規資訊
The supplied search results identify the manufacturer, package, memory, speed, I/O count, oscillator, and tray packaging, but do not provide compliance declarations. No RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification claim is inferred.
