MC9S08PT8VTG - 8-Bit 20MHz S08 MCU | NXP Semiconductors
N.º de pieza: MC9S08PT8VTG ✗ Fin de vidaMC9S08PT8VTG Descripción general
An S08 microcontroller is an 8-bit embedded-processing device designed to execute control, measurement, and user-interface tasks in compact embedded systems. Within the product hierarchy, it is an MCU based on the HCS08 core, combining program flash, data RAM, digital I/O, timer resources, and analog conversion functions in one package. This integration reduces the number of external components required in small control systems.
The MC9S08PT8VTG operates at up to 20 MHz and includes 8 KB of flash for firmware storage plus 2 KB of RAM for working data. Its 5 V-oriented operating range supports industrial equipment, appliance controls, and human-machine interfaces that require an embedded controller capable of deterministic digital and analog signal handling. The listed industrial temperature range extends from -40 °C to +105 °C.
The device includes a 12-bit ADC, an 8-bit data bus, and an S08 processor core. The 16-pin TSSOP package is a surface-mount format with 0.65 mm pitch. Its industrial temperature rating and integrated analog conversion make the MCU suitable for compact sensing and control platforms where an external host processor would add unnecessary system complexity.
Typical applications include appliance control panels, small industrial user interfaces, digital measurement instruments, sensor-conditioning systems, and embedded products requiring a low-cost 8-bit control engine. NXP describes the S08P family as reusable for migration from existing S08 products, helping preserve core, intellectual property, and tooling continuity during product revisions.
A hardware design should use the manufacturer datasheet for the exact pin assignments, power requirements, programming connections, and decoupling recommendations. Pay particular attention to the 2.7 V to 5.5 V supply range, the 20 MHz operating limit, and the 16-pin TSSOP footprint when planning routing and assembly.
This product overview combines the manufacturer specification highlights with practical sourcing, application, and design guidance. It also distinguishes verified device attributes from information that must be confirmed in the full datasheet before schematic release or PCB sign-off.

Aplicaciones típicas
MC9S08PT8VTG es adecuado para 6 aplicacións: Appliance Control Panel, Industrial User Interface, Digital Measurement Instrument, Sensor Conditioning System, Small Motor Sequencing Controller, Harsh Environment User Interface.
Appliance Control Panel
The MC9S08PT8VTG fits compact appliance control panels that require local button handling, status feedback, motor or valve sequencing, and analog sensing. Its 8-bit S08 core and 20 MHz clock provide sufficient control bandwidth for real-time tasks, while 8 KB of flash accommodates application firmware and 2 KB of RAM supports operating variables. The 2.7 V to 5.5 V range is suitable for a regulated 5 V appliance architecture, and the -40 °C to +105 °C rating supports industrial ambient conditions. Use the exact pin and peripheral assignments from the NXP datasheet when allocating keypad, display, actuator, and sensor interfaces.
Recomendado
Industrial User Interface
The MC9S08PT8VTG can serve as the embedded controller in a compact industrial user interface containing status indicators, push buttons, encoders, and a small display. Its 20 MHz maximum clock frequency supports responsive input scanning and display updates, while the 8-bit architecture and 8 KB program memory target focused control tasks rather than graphics-heavy workloads. The 12-bit ADC can serve auxiliary analog monitoring when suitable front-end conditioning is included. Its industrial temperature range of -40 °C to +105 °C is useful for enclosure temperature variation, but EMC, ESD, isolation, and functional-safety requirements must be assessed independently for the complete product.
Recomendado
Digital Measurement Instrument
The MC9S08PT8VTG is appropriate for compact digital measurement instruments where a front end converts an analog quantity into a digital value and the MCU performs calibration, filtering, display control, and data handling. The integrated 12-bit ADC provides the conversion interface, and the 20 MHz S08 core can manage control logic around the conversion process. Its 2 KB RAM is suitable for short-lived measurement buffers and working variables, while 8 KB of flash supports calibration tables and firmware. Analog accuracy still depends on the reference source, input impedance, sampling strategy, grounding, and PCB layout, all of which should be designed against the manufacturer recommendations.
Recomendado
Sensor Conditioning System
The MC9S08PT8VTG fits sensor-conditioning systems that must acquire an analog input, apply thresholds or calculations, and report the result through a local display, serial interface, or control output. Its 12-bit ADC supports sensing resolution, while the 8-bit S08 processor provides enough execution speed for acquisition sequencing and basic digital filtering. The 2.7 V minimum operating voltage permits integration with compatible low-voltage sensor circuits, and the 5.5 V maximum simplifies designs using a common 5 V rail. Avoid using the ADC pin as a general-purpose high-current output, and follow the datasheet for analog-pin multiplexing and acquisition timing.
Recomendado
Small Motor Sequencing Controller
The MC9S08PT8VTG can control small motors, solenoids, relays, or valves in compact equipment when the outputs include suitable driver circuitry. At up to 20 MHz, the S08 core can execute deterministic state machines, debounce inputs, coordinate start and stop sequences, and supervise feedback signals. The 8 KB flash supports compact firmware, while 2 KB of RAM is sufficient for modest queues and state structures. The MCU itself should not directly drive inductive loads; use appropriately rated transistors or driver stages, add protection required by the load, and design flyback paths according to the load topology and device datasheets.
Recomendado
Harsh Environment User Interface
The MC9S08PT8VTG is relevant to user-interface and control assemblies in harsh environments where ambient temperature may reach +105 °C. Its industrial temperature grade, 5 V-capable operating range, and integrated 12-bit ADC support sensing and local logic in equipment exposed to temperature variation. The 16-pin TSSOP package can support compact board layouts, provided the manufacturer land pattern, soldering profile, and reflow conditions are followed. For machinery, appliances, or safety-regulated products, verify creepage, clearance, grounding, isolation, and functional-safety requirements rather than treating MCU temperature qualification as complete product approval.

Notas de diseño
Design the supply for the documented 2.7 V to 5.5 V operating range and place the manufacturer-recommended bypass capacitors close to the supply and ground pins. Check startup current, peripheral loading, and regulator tolerance across temperature. The 5 V-oriented S08P architecture should not be assumed to permit operation above 5.5 V, even if an adjacent connector carries a higher nominal voltage.
Use the 16-pin TSSOP land pattern and solder mask geometry specified by NXP rather than constructing the footprint from nominal pin spacing alone. Confirm courtyard clearance, annular-ring dimensions, paste volume, and the exposed lead geometry through the package drawing. Place the decoupling network at the associated IC pins and route high-current or switching-node connections away from the MCU supply and analog input traces.
Do not treat the reported 37 I/O figure as a pin count for this 16-terminal package. The exact MC9S08PT8VTG has 16 terminals, so assign functions only after reviewing the manufacturer pin-connection table and multiplexed peripheral options. Also account for package variant and temperature suffix differences when comparing MC9S08PT8VTG with other S08P devices.
For analog measurements, keep sensor traces short, maintain a continuous ground reference, and isolate switching outputs and their return currents from the ADC region. Use a stable reference and acquisition arrangement appropriate for the 12-bit converter. Review source impedance, sampling capacitance, and acquisition timing in the full datasheet because the external sensor network can determine practical measurement accuracy.
The device is NRND, so new production designs should include a deliberate sourcing and migration review rather than assuming long-term continuity. Preserve application firmware knowledge, S08 tooling, package constraints, and peripheral requirements during any migration. A candidate with the same family name is not a drop-in substitute unless its pinout, memory, clock, electrical limits, and software behavior have all been verified.
