MC9S08PA8VWJ - 8-Bit 20MHz 8KB Flash MCU | NXP
MPN: MC9S08PA8VWJ ✓ AktifMC9S08PA8VWJ Ringkasan
An 8-bit microcontroller is a compact embedded controller built around an 8-bit central processing unit, flash program memory, data memory, and dedicated peripheral modules. MC9S08PA8VWJ belongs to the S08 family of 8-bit microcontrollers and sits within the broader hierarchy of embedded processors, microcontrollers, and semiconductor devices. Its combination of an HCS08L core and integrated analog and timing resources is useful when a product requires local control without the cost or complexity of a higher-performance processor.
Key features include up to 20 MHz operation, 8 KB of read, program, and erase flash, 8 KB of SRAM listed in distributor listings, and support for as many as 40 interrupt or reset sources. The integrated ADC supports cost-effective analog measurement, while the analog comparator and motor-control FlexTimer reduce the need for separate peripheral components. Four levels of nested interrupt support provide deterministic control for embedded tasks and real-time event handling.
The device is specified for operation from 2.7 V to 5.5 V across a temperature range of -40 °C to 105 °C. This voltage and temperature coverage allows the same architecture to serve industrial controls, appliance controllers, sensor modules, compact motor-control boards, and consumer products. Its 20-pin SOIC package is also compatible with conventional surface-mount assembly and board-layout practices used for small embedded controllers.
Typical applications include low-cost appliance control, industrial sensing, compact motor control, analog monitoring, and small consumer products. The integrated ADC is particularly useful when a design must measure an analog sensor input, while the FlexTimer and comparators support timing-sensitive and threshold-based functions. Software can also use the interrupt structure to coordinate multiple control events without requiring a separate programmable logic device.
For a new design, confirm the exact peripheral assignment, pin multiplexing, programming method, and memory map against the manufacturer datasheet before assigning PCB functions. Decoupling and signal-integrity requirements should be planned around the power pins and any communication signals used by the product. The 20-pin footprint limits pin count, so applications requiring many external signals should begin with a complete pin-level feasibility review.
This product page brings together the core device specifications, package information, sourcing guidance, practical application context, and drop-in alternatives for engineers evaluating an MC9S08PA8VWJ-based design. It supports faster initial screening while the manufacturer datasheet remains the controlling reference for detailed electrical limits, registers, timing, and board implementation.

Compact Motor-Control Module
The MC9S08PA8VWJ fits small motor-control modules because it combines an HCS08L core with a dedicated motor-control FlexTimer, analog comparators, and an ADC. These resources can support timing, current or position sensing, and control-loop updates within one compact 20-pin package. The controller operates from 2.7 V to 5.5 V and includes flash, SRAM, and EEPROM for application code and retained parameters. Validate timing, noise immunity, thermal performance, and actuator drive circuitry for the specific motor.

Analog Sensor Interface
The MC9S08PA8VWJ can serve as the controller for a compact analog sensor interface because its integrated ADC and analog comparator reduce the need for external signal-conditioning components. The 8-bit CPU can perform thresholding, calibration, filtering, and digital reporting at up to 20 MHz, while 8 KB of SRAM supports temporary measurement data. Its 2.7 V minimum operating voltage offers flexibility for low-power sensor systems. Keep high-impedance analog traces short and use grounded guarding techniques where the sensor source impedance is high.

Low-Power Embedded Control
The MC9S08PA8VWJ works for low-power embedded controls that need deterministic interrupt handling, local EEPROM, and a compact set of analog and timing peripherals. The architecture supports up to 40 interrupt or reset sources and four levels of nested interrupts, allowing important events to be prioritized. Its 2.7 V to 5.5 V operating range supports energy-conscious 3.3 V systems, while the 20-pin SOIC package limits board area. Actual standby and active-current behavior should be evaluated against the product power budget.

Diferensiator Kunci
- Integration reduces external analog and timing components (vsMC9S08PA8AMTG)
- 20 MHz performance with modest memory requirements (vsMC9S08PA8AMTG)
- Broad supply-voltage range (vsMC9S08PA8AMTG)
Catatan Desain
Follow the NXP recommended layout for bypass capacitors and route the ground return directly to the device ground pins. Place input capacitors close to the supply entry and output-capacitor requirements close to the relevant pins. Confirm the pin-one orientation and exposed package geometry against the exact ordering-code drawing before fabrication; the 20-pin footprint leaves little room for last-minute rerouting.
Keep analog comparator and ADC inputs away from switching edges, motor-drive nodes, and high-current return paths. Use a continuous ground reference beneath sensitive routes where board construction permits, and terminate unused inputs according to the datasheet guidance. Verify acquisition timing and source impedance with the intended sensor or divider because the 8-bit conversion result also depends on conditioning, reference stability, and firmware averaging.
Do not assume that parts sharing the MC9S08PA8 base designation have identical suffix attributes. Before substituting MC9S08PA8AMTG, compare the ordering-information entries for clock range, temperature grade, qualification, flash organization, SRAM, package dimensions, and pin multiplexing. Recheck reset, clock, debug, and programming requirements as well; a shared family name alone does not establish production interchangeability.
Budget the MCU supply across the full 2.7 V to 5.5 V operating range and include margin for connected sensors and I/O loads. Check absolute maximum ratings, operating voltage, and power-consumption tables in the manufacturer datasheet for the selected configuration. Use local decoupling to limit supply disturbance from timer switching and peripheral activity, and validate the rail during motor startup or other high-current events.
The -40 °C to 105 °C specification defines the operating range but does not mean the device dissipates its maximum power at every temperature. Use the package power data and application thermal information to evaluate the chosen PCB footprint. For compact enclosed products, confirm that copper area, airflow, and nearby heat sources keep the operating conditions within the manufacturer limits.
Informasi Konformitas
The available manufacturer and distributor information does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Request the current compliance and qualification documents for the exact ordering code.
