N.º da peça: MC9S08PT8VLC ✗ Fim de vidaMC9S08PT8VLC Visão geral
The S08 family belongs to the broader hierarchy of 8-bit microcontrollers, microcontrollers, embedded processors, and programmable semiconductor devices. These devices are commonly used where simple deterministic control, low system complexity, and cost-effective integration are more important than high arithmetic throughput. The MC9S08PT8VLC is appropriate for products that need local sensing, actuator control, keypad or touch input, and modest serial communications without relying on a higher-cost 32-bit processor.
Key features include an 8-bit S08 CPU, 20 MHz clock capability, 8 KB flash, touch sensing interface support, EEPROM integration, and a motor control flexible timer. The 32-LQFP package provides a conventional surface-mount footprint suitable for automated assembly and compact industrial or consumer-control boards. The device is identified as NRND by NXP, so engineers should confirm lifecycle status, availability, and any product-change notices before starting a new production design.
Typical uses include touch-controlled appliances, compact motor-control modules, keypad interfaces, low-cost embedded controllers, and small control boards that combine sensing with timer-driven output functions. The 20 MHz S08 core provides more timing margin than slower 8-bit devices while retaining the simplicity of the 8-bit architecture.
For PCB implementation, follow the manufacturer pin-assignment table and preserve the recommended decoupling and oscillator layout. Confirm the exact exposed-pad or thermal requirements from the package drawing, and validate touch-sensing traces and motor-drive connections against the application circuit. The page combines lifecycle information, package details, technical alternatives, and design guidance for component selection and sourcing.
The MC9S08PT8VLC is best suited to engineers who want an established NXP S08 control solution with touch-sensing and motor-control features in a 32-LQFP package. Because the part is NRND, use it primarily for existing designs, approved redesigns, or applications where an equivalent has been formally qualified.
This page summarizes the component identity, electrical and packaging characteristics, sourcing references, drop-in candidates, and practical design considerations for integrating the MC9S08PT8VLC into embedded control systems.

Aplicações típicas
MC9S08PT8VLC é adequado para 6 aplicaçãos: Touch-Controlled Household Appliances, Small Motor-Control Modules, Keypad and Human-Interface Controllers, Low-Cost Embedded Control Boards, Appliance Status and Safety Sequencing, EEPROM-Configured Control Products.
Touch-Controlled Household Appliances
The MC9S08PT8VLC fits touch-controlled appliances because the S08PT family integrates a touch-sensing interface alongside EEPROM and timer resources. Its 20 MHz S08 core can scan touch inputs, manage product states, drive indicators, and coordinate motor or relay timing without requiring a higher-performance processor. The 8 KB flash provides space for a compact control program, while EEPROM can retain calibration or configuration data. In a production design, the touch-electrode layout, scan timing, noise immunity, and pin multiplexing should be validated against the manufacturer guidance. The 32-LQFP package also supports standard automated surface-mount assembly and a compact control PCB.
Recomendado
Small Motor-Control Modules
The MC9S08PT8VLC is appropriate for compact motor-control modules because the S08PT family provides a motor control flexible timer and operates at up to 20 MHz. The timer resources can support deterministic switching, speed-control, or sequencing tasks, while the 8-bit CPU handles commands and supervisory logic. At 3.3 V or 5 V operation, the device can be paired with a suitable driver stage rather than driving a motor directly. Engineers should verify PWM channels, timer modes, fault handling, pin assignment, and clock configuration in the datasheet. Any replacement must be checked for equivalent timing behavior and peripheral mapping, not merely the same package outline.
Recomendado
Keypad and Human-Interface Controllers
The MC9S08PT8VLC can serve as a dedicated keypad or human-interface controller in compact control panels. Its 20 MHz processing rate provides useful timing margin for debouncing, scanning, indicator updates, and serial command handling, while the integrated EEPROM can store configuration values such as calibration or mapping data. The S08PT touch-sensing interface also creates an opportunity to unify capacitive keys into the same controller architecture. The 32-LQFP package provides enough pins for typical control signals while keeping the board compact. Firmware and PCB validation should confirm alternate-function selection, programming signals, reset behavior, and the exact external circuitry required by the chosen interface.
Recomendado
Low-Cost Embedded Control Boards
The MC9S08PT8VLC is suitable for low-cost embedded control boards that need a small processor, nonvolatile code storage, and deterministic peripheral control. The 8-bit S08 architecture keeps software and hardware complexity manageable for simple products, while 20 MHz operation and 8 KB flash provide room for state machines, calibration, communication routines, and production self-tests. The 3.3 V or 5 V supply flexibility supports both industrial control logic and consumer-oriented boards. Because the part is NRND, teams should minimize redesign risk by preserving its footprint and software architecture when an existing platform is being maintained. For new platforms, compare the device against currently recommended NXP MCUs before committing a long product life.
Recomendado
Appliance Status and Safety Sequencing
The MC9S08PT8VLC can coordinate appliance status, interlocks, and sequencing functions where deterministic timing is more important than networking performance. Its 20 MHz 8-bit core is appropriate for monitoring switches, updating indicators, and sequencing actuators through timer-controlled outputs. The S08PT family's motor control flexible timer adds value where a motor participates in the operating sequence, while EEPROM can preserve configuration and diagnostic counters. For safety-related implementations, use the MCU only within the scope validated by the product's safety architecture and applicable standards. Pin selection, watchdog use, brownout behavior, and fault-response paths must be verified from the exact manufacturer documentation before production release.
Recomendado
EEPROM-Configured Control Products
The MC9S08PT8VLC is useful in products that retain calibration, serial numbers, operating profiles, or configuration maps in EEPROM. The integrated EEPROM reduces the need for external nonvolatile memory in compact designs, while 8 KB of flash holds application code and the 20 MHz core supports responsive state management. A practical implementation can reserve EEPROM for field-configurable parameters, apply write-cycle limits, and include checksum or wear-management routines in firmware. Because the exact endurance and write timing specifications are not stated in the product-page material, engineers should consult the manufacturer datasheet before defining update frequency or product-life requirements. Pin allocation and write-protection practices should also be reviewed during PCB design.

Notas de projeto
Design the supply rail for either 3.3 V or 5 V operation and confirm all external components meet the selected voltage. Place the required bypass capacitors close to the corresponding power and ground pins, and verify capacitor voltage ratings, effective capacitance, and ESR requirements against the manufacturer guidance. Because the product-page material does not state the complete electrical limits, use the official datasheet for supply range, maximum current, and decoupling values before schematic release.
Follow the NXP package drawing and pin-description table when assigning the 32-LQFP footprint. Keep programming and debug access accessible, preserve the intended clock and reset topology, and route sensitive touch-sensing inputs away from switching nodes and high-current motor-drive traces. Confirm whether exposed-pad or thermal land requirements apply to the exact package variant. A footprint library entry alone is not a substitute for checking pin 1 orientation and manufacturer land-pattern guidance.
Do not treat a shared 32-LQFP outline as proof of drop-in compatibility. Before substituting MC9S08QE32CLCR, compare power pins, clock pins, programming signals, peripheral functions, timer channels, memory size, and interrupt assignments. Also distinguish functional equivalence from ordering variants: MC9S08PT8VLC-FR is a packaging or ordering designation, not a separate design with different electrical functionality. Complete firmware, timing, and hardware qualification before substitution.
For touch and motor-control applications, validate signal integrity in the assembled board rather than relying on nominal peripheral features. Touch electrodes can be affected by trace length, grounding, enclosure materials, switching noise, and humidity. Motor outputs require suitable isolation, driver transistors, protection, and fault handling. Use the manufacturer's application guidance to establish safe timing, input filtering, and board-layout margins before production testing.
Informações de conformidade
