MC9S08QE16CFM - 8-Bit 50MHz 16KB MCU | NXP Semiconductors
料号： MC9S08QE16CFM ✗ 停产MC9S08QE16CFM 概述
A microcontroller is a semiconductor device that combines a processor core, program memory, data memory, peripherals, and interface circuitry on one integrated circuit. The S08QE family belongs to the broader embedded-processor hierarchy: MCU, embedded controller, semiconductor, and electronic control component. In a system, this device executes firmware, samples inputs, controls outputs, and manages communications through hardware peripherals rather than relying on external discrete processing components.
The verified data identifies an 8-bit architecture, 50 MHz operating frequency, and 16 KB flash organized as 16K x 8 bits. These headline values define a processor intended for compact embedded applications. The 50 MHz clock provides execution headroom for event handling and peripheral control, while 16 KB of flash limits firmware capacity and should be checked during application planning. Integrated USB expands the interface options for connected equipment, while low-power modes support designs where energy consumption between active operations is important.
The MC9S08QE16CFM is housed in a 32-QFN-EP package with a 5 mm by 5 mm footprint. The exposed-pad package is intended for surface-mount assembly and provides a central thermal and electrical land pattern rather than a large through-hole body. Because the NXP product page marks the device as End of Life, procurement should begin with stock verification and a manufacturer-approved migration review rather than assuming unrestricted new production.
Typical uses include compact USB-connected control nodes, industrial interface modules, appliance controllers, sensor-hub assemblies, and low-power embedded instruments. These applications benefit from the 8-bit S08 core, integrated USB, 16 KB flash, and low-power modes. Firmware size, USB class support, peripheral mapping, clock configuration, and board-level power requirements must still be confirmed against the complete manufacturer datasheet before design release.
A key design consideration is lifecycle risk. Because the NXP page identifies this MPN as End of Life, engineers should verify inventory authenticity, inspect date codes, and compare any migration device by pinout, voltage, memory, clock, USB, and firmware requirements. Do not assume that a similarly named S08QE device is a drop-in replacement without complete datasheet validation.
This page consolidates the verified 50 MHz, 16 KB, 8-bit, USB, package, lifecycle, distributor, and sourcing information while separating documented facts from parameters that still require manufacturer-datasheet confirmation. It is intended to support initial component selection and procurement planning, not to replace the complete electrical and pin-level documentation.

典型应用
MC9S08QE16CFM 适用于 6 应用s: Compact USB Control Node, Industrial Interface Module, Low-Power Sensor Hub, Appliance Control Board, USB Service Adapter, Compact Measurement Controller.
Compact USB Control Node
The MC9S08QE16CFM fits preliminary USB-control designs that combine an 8-bit processor, a 50 MHz clock, and 16 KB of flash in a compact 5 mm by 5 mm package. Integrated USB can reduce the need for a separate host controller when the application uses only the roles and device classes supported by the S08QE device. Engineers should place the MCU near the connector and protection network, preserve short return paths, and validate power-state behavior. The principal trade-off is limited program space: 16 KB must accommodate the complete USB-facing firmware, configuration, and application logic without leaving inadequate maintenance margin.
推荐
Industrial Interface Module
The 50 MHz S08 core gives the MC9S08QE16CFM useful processing speed for compact industrial interface modules that coordinate sensors, status indicators, and host-side communications. Its 8-bit architecture is appropriate for control-oriented tasks rather than computationally intensive signal processing, while 16 KB of flash supports a focused firmware image. The 32-QFN-EP footprint reduces board area, but the exposed-pad land pattern must follow NXP assembly requirements. Before release, verify industrial temperature limits, ESD protection, isolation requirements, and analog or communication peripheral assignments against the complete datasheet.
推荐
Low-Power Sensor Hub
MC9S08QE16CFM is relevant to a low-power sensor hub because the verified product information explicitly lists low-power modes alongside an 8-bit control core. A duty-cycled design can use those modes between sensor sampling or host-polling events, potentially reducing energy use when the MCU, USB interface, and external sensors are inactive. Actual battery performance depends on wake latency, active current, leakage, regulator efficiency, and sensor load, none of which are quantified in the supplied data. Firmware must also fit within 16 KB while managing sampling, buffering, communications, and fault recovery.
推荐
Appliance Control Board
The MC9S08QE16CFM can serve as the central controller in a compact appliance when the firmware manages buttons, indicators, sensors, and safety-state sequencing rather than demanding a high-end processor. Its 50 MHz maximum frequency supports responsive event handling, and integrated USB can provide a service or configuration connection. The 16 KB flash constraint requires disciplined code organization and may rule out large protocol stacks or feature-heavy user interfaces. Hardware design must confirm relay, motor, heater, and mains-related isolation boundaries; none of those interface details were included in the verified search data.
推荐
USB Service Adapter
Integrated USB makes MC9S08QE16CFM a candidate for a compact service adapter that exposes equipment status, configuration data, or diagnostic commands. The S08QE device combines an 8-bit core, 16 KB flash, and low-power modes in a small surface-mount package, allowing the adapter to avoid a larger host computer while still supporting a wired maintenance connection. Designers must budget carefully for USB descriptors, command handlers, boot behavior, and future field updates within 16 KB. Electrical compliance and supported USB speed or class should be confirmed from the full NXP documentation rather than inferred from the distributor snippet.
推荐
Compact Measurement Controller
The MC9S08QE16CFM can coordinate measurement sequencing and data handling in a compact instrument when the required algorithm fits its 8-bit architecture and 16 KB flash budget. Its 50 MHz rating supports responsive peripheral control, while low-power modes may help between measurement cycles. The MCU is not a substitute for a dedicated precision converter or analog front end; those components must be evaluated separately for resolution, accuracy, bandwidth, and noise. Calibration data, interface protocols, and buffering also consume memory, so engineering should estimate firmware and RAM requirements before committing to this device.

设计说明
Do not treat a related MC9S08QE family member as a drop-in substitute without a complete pin and software comparison. The verified search data establishes the target's 32-QFN-EP package, 50 MHz clock, 16 KB flash, integrated USB, and low-power modes, but it does not provide individual pin assignments. Check power, ground, exposed pad, reset, clock, programming, USB, and every peripheral signal against the complete datasheet before releasing a replacement board.
Use the manufacturer's exact exposed-pad land pattern and assembly recommendations rather than a generic 32-QFN footprint. The EP designation makes pad geometry and paste behavior assembly-critical. Preserve uninterrupted ground connectivity where the datasheet permits, place required decoupling at the associated supply pins, and validate USB differential routing against the supported electrical specification. The supplied data confirms a 5 mm by 5 mm package but not pad dimensions or stack-up guidance.
Plan the power tree and low-power strategy from the complete electrical specification. The presence of low-power modes does not establish system battery life because current in active, sleep, and shutdown states plus regulator losses determine the result. Likewise, USB operating states can change current demand. Verify the target voltage range, absolute maximum ratings, USB bus requirements, decoupling values, and startup behavior in the manufacturer datasheet before schematic release.
Treat procurement as an end-of-life supply-chain project. The NXP page labels MC9S08QE16CFM End of Life, and LCSC shows a starting price of $1.2684 as of 2026-10-21, but neither fact guarantees ongoing production or traceability. Request authorized-distributor confirmation, inspect date codes and markings, document lot traceability, and secure enough inventory for the product's service life before freezing new production units.
合规信息
The verified search data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. NXP identifies the product as End of Life, but lifecycle status does not establish compliance.
