MC9S08QE64CFT 概要
An HCS08 microcontroller is a compact CISC-based embedded controller that combines a processor core, Flash program memory, RAM, peripherals, and general-purpose I/O on one semiconductor. The MC9S08QE family belongs to the Flexis MCU product line and combines low-power operation with dedicated human-interface functions. This makes it relevant to portable appliances, keypads, meters, simple control panels, and other systems that need local sensing and display support.
Verified distributor data identifies a 50.33-MHz HCS08 CPU, a 1.8 V to 3.6 V supply range, 28 I/O ports, and a 48-QFN-EP package. One retrieved technical summary also states that the CPU can operate to 50.33 MHz from 2.1 V and to 20 MHz down to 1.8 V across temperature. Other verified family data identifies 4 KB RAM, a 10-channel 12-bit ADC, and 26 general-purpose I/O pins for MC9S08QE64CLC; those values are not assumed to be identical for MC9S08QE64CFT unless directly stated.
The integrated keyboard interface and LCD driver distinguish this MCU from general-purpose small microcontrollers. Engineers can connect input controls and display signals directly to dedicated peripherals, reducing component count and board area. The 64 KB Flash capacity provides room for application firmware, while the 8-bit architecture can be adequate for straightforward control loops, state machines, and human-interface tasks.
MC9S08QE64CFT is identified as active by one technical listing, while the official NXP search result also contains an End of Life overview. Because these signals conflict, engineers should confirm current lifecycle, ordering, and replacement status directly with NXP before committing a production design.
For implementation, verify the voltage-dependent maximum bus speed, exposed-pad connection, decoupling, programming interface, and unused-pin requirements against the manufacturer datasheet. The QFN footprint is compact but requires careful land-pattern and reflow control. A hardware migration should compare pin multiplexing, interrupt mapping, timer resources, memory size, voltage limits, and software compatibility rather than treating a matching package as sufficient proof of interchangeability.

MC9S08QE64CFT の用途: 6 件s: Portable Keypad Controller, LCD Instrument Panel, Battery-Powered Handheld Device, Simple Industrial Control Module, Human-Machine Input Interface, Compact Appliance Controller.
Portable Keypad Controller
The MC9S08QE64CFT fits portable keypad products because it combines an 8-bit HCS08 processor, 64 KB Flash, and an integrated keyboard interface in one device. The verified supply range of 1.8 V to 3.6 V supports low-voltage portable systems, while the CPU can reach 50.33 MHz from 2.1 V for interface-intensive work. Use the keyboard peripheral to scan controls and firmware to debounce, interpret, and map keys. Compared with a discrete matrix scanner, the integrated interface can reduce board area and firmware overhead. The main design check is whether the selected key count, wake behavior, and debounce strategy fit the exact peripheral configuration.
おすすめ
LCD Instrument Panel
The MC9S08QE64CFT is suitable for compact meter and control-panel designs that need local display logic. Its verified integrated LCD driver removes the need for a separate display interface IC, while 64 KB of Flash provides space for menus, measurement control, icons, and communication routines. The processor operates from a 1.8 V to 3.6 V supply, making it relevant to battery-powered instruments, although actual low-power performance must be checked from the full datasheet. Layout work should route LCD outputs away from sensitive analog inputs and provide clean grounding between display drive and measurement circuitry.
おすすめ
Battery-Powered Handheld Device
The MC9S08QE64CFT can serve as the control center in a battery-powered handheld product because its verified 1.8 V minimum supply voltage aligns with low-energy systems. The 64 KB Flash capacity is adequate for embedded user-interface firmware and state-machine logic, while the 48-QFN-EP package limits board footprint. Its integrated keyboard and LCD functions target portable-electronics use directly. Designers should still quantify sleep current, active current, LCD-drive load, and wake latency from the manufacturer data because those values were not present in the supplied excerpts.
おすすめ
Simple Industrial Control Module
The MC9S08QE64CFT can support compact industrial control modules that combine local buttons, a display, and embedded sequencing logic. Its industrial temperature-grade classification and 1.8 V to 3.6 V operating range make it relevant to low-voltage equipment, while the 50.33-MHz HCS08 CPU provides ample instruction throughput for state machines and supervisory functions. The 28-port listing offers a substantial interface budget. Engineers should confirm pin multiplexing, I/O tolerance, reset behavior, and exposed-pad layout in the full datasheet before assigning external connectors.
おすすめ
Human-Machine Input Interface
The MC9S08QE64CFT is well matched to human-machine interfaces because its integrated keyboard interface and LCD driver handle two common front-panel tasks. Firmware can translate front-panel commands, update display states, and coordinate low-power behavior inside one 8-bit controller. The verified 64 KB Flash provides more capacity than a minimal logic device, and the compact 48-QFN-EP package supports dense assemblies. For reliable products, debounce timing, display glass loading, ESD protection, and connector protection must be designed around the actual electrical limits rather than inferred solely from the 28-port headline specification.
おすすめ
Compact Appliance Controller
The MC9S08QE64CFT can serve as the main controller in a compact appliance with local keys, an LCD, and modest decision logic. Its 50.33-MHz maximum CPU frequency, 64 KB Flash, and low-voltage operation provide more capability than a basic fixed-function controller while keeping the system economical. The integrated human-interface peripherals can shorten development time by avoiding a separate keyboard scanner and display bridge. Product designers should verify motor or heater control interfaces, safety shutdown behavior, brownout response, and power dissipation because those subsystem requirements are not quantified in the supplied source snippets.

設計ノート
Treat the 48-QFN exposed pad as a thermal and electrical land, not as an optional area. Follow the manufacturer land pattern exactly, provide a continuous or correctly segmented ground connection as specified, and plan paste coverage and reflow inspection for the no-lead terminals. The supplied data establishes a 7 mm by 7 mm HVQCCN package but does not provide its dimensional drawing, so do not derive land geometry from generic 48-QFN examples.
Design the supply rail for the intended clock rather than only the nominal voltage range. Verified data allows 50.33 MHz from 2.1 V but limits the stated CPU frequency to 20 MHz from 1.8 V across temperature. Place local decoupling close to the supply and ground pins, verify startup and brownout behavior in the complete datasheet, and account for LCD-drive and external-interface loading before selecting the regulator.
Separate LCD-drive and keyboard-scan routes from precision analog or timing-sensitive inputs where possible. Keep ground returns short, provide a solid ground reference under the device where the package drawing permits, and route high-current or externally switched signals away from the MCU and display region. Exact grounding and isolation guidance should come from the manufacturer application material because no reference design was supplied in the verified excerpts.
Do not infer a safe replacement from an S08 label, equal Flash capacity, or a similar QFN pin count. Validate alternate-function mappings, interrupt vectors, memory organization, clock-tree limits, ADC resources, timers, and exposed-pad connections. The lifecycle evidence is also mixed: a technical page says ACTIVE, while the NXP search result exposes an EOL overview. Obtain current manufacturer confirmation before committing to new production.
コンプライアンス情報
The verified results classify MC9S08QE64CFT as industrial grade but provide no RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification declaration. Industrial temperature grade does not establish AEC-Q100 qualification.
