MC68HC908KX2CP Descripción general
The MC68HC908KX2 belongs to the 8-bit microcontroller category, a microcontroller class that integrates a processor core, memory, I/O, timers, and communication peripherals on one semiconductor device. Within the broader embedded-systems hierarchy, it is an HCMOS microcontroller, a semiconductor component intended for control, measurement, and automation products. The 16-DIP package is mechanically straightforward for through-hole assembly, prototyping, repair, and legacy equipment maintenance.
Verified source data confirms the 8-bit architecture, 8 MHz operating frequency, 2 KB Flash memory, 2K x 8 organization, and 16-PDIP package. The NXP product-brief search result also identifies an internal clock generator, serial communications interface, analog-to-digital converter, and timebase module as important family features. These peripherals can reduce external component count in applications requiring periodic sensing, timing, serial communication, or basic control outputs. Detailed electrical limits, memory map, ADC resolution, I/O ratings, and timing parameters were not supplied in the retrieved data and require confirmation from the manufacturer datasheet.
Typical uses include small industrial controllers, sensor-interface modules, appliance-control boards, laboratory instruments, communications equipment, and legacy embedded products. The internal clock generator can simplify designs where an external crystal is not necessary, while the SCI supports serial links to sensors, host computers, or service equipment. The ADC and timebase module make the device useful for systems that must monitor analog inputs and perform periodic actions without a larger processor.
Designers should verify the exact pinout, supply voltage, oscillator options, memory map, peripheral multiplexing, and programming method in the MC68HC908KX2CP datasheet before layout or firmware development. The 16-pin DIP footprint is useful for replacement work, but it is not a surface-mount package. This page distinguishes the verified 8 MHz MC68HC908KX2CP from the separately listed MC68HC908KX2CP-MO listing, which appears under a 32 MHz description and should not be assumed to be electrically identical.
This page combines verified distributor specifications, the NXP 68HC908KXPB product-brief reference, and practical selection guidance for engineers evaluating a legacy 8-bit embedded controller. Because the supplied web results contain conflicting or incomplete details for related suffixes, verify the exact ordering code and manufacturer datasheet before committing to a purchase or replacement.

Aplicaciones típicas
MC68HC908KX2CP es adecuado para 6 aplicacións: Small Industrial Control Panel, Sensor Interface Module, Appliance Control Board, Legacy Communication Equipment, Basic Data Acquisition System, Educational and Prototype Electronics.
Small Industrial Control Panel
The MC68HC908KX2CP can serve as the central controller in a compact panel that accepts discrete inputs, evaluates operating states, and drives indicators or relays. Its 8-bit architecture is appropriate for straightforward supervisory logic, while the family ADC permits monitoring of analog signals and the timebase module supports periodic control tasks. The 8 MHz operating point provides useful processing headroom for legacy control systems, although timing should be verified against the slowest required input and output behavior. The 16-PDIP package also simplifies repair in equipment designed around through-hole assembly.
Recomendado
Sensor Interface Module
The MC68HC908KX2CP is a practical choice for a small sensor-interface module that must read analog conditions and communicate results to a host or peripheral controller. The 68HC908 family's ADC and SCI provide the basic functional path from sensing to serial communication, while the internal clock generator can reduce dependence on an external clock source. Firmware must define the sampling cadence, input filtering, calibration method, and serial framing. Before selecting the device, verify the ADC resolution, operating voltage, conversion timing, and available I/O count in the exact datasheet.
Recomendado
Appliance Control Board
For appliances and laboratory equipment, the MC68HC908KX2CP can coordinate button inputs, operating modes, timing functions, status LEDs, and simple actuator outputs. Its 8 MHz clock and 8-bit architecture suit deterministic control loops that do not require high-end connectivity or large data storage. The SCI can provide a service or diagnostic link, while the timebase module may assist periodic scheduling. The 16-PDIP format is advantageous when maintaining a through-hole design, but the final design must confirm pin multiplexing, reset requirements, supply limits, and programming provisions.
Recomendado
Legacy Communication Equipment
The MC68HC908KX2CP can be used in legacy serial equipment where an SCI-based control path is sufficient and the existing PCB uses a 16-pin through-hole controller. The part is most appropriate when maintaining an established firmware and board rather than starting a new high-performance design. The internal clock generator and SCI can simplify service-oriented equipment, but the communication baud-rate tolerance, framing, and electrical interface must be checked against the original system. A level shifter or protection device may also be required because the MCU supply and logic levels are not established by the supplied search snippets.
Recomendado
Basic Data Acquisition System
The MC68HC908KX2CP can form the core of a basic data-acquisition system when the required measurement rate, channel count, and storage capacity are modest. The family ADC supports analog measurement, the SCI can stream results to a computer or logger, and the timebase module can establish periodic sampling. Firmware should account for acquisition latency, conversion timing, input filtering, and data framing. The 2 KB Flash memory constrains complex local buffering and firmware features, so applications requiring large logs, networking stacks, or high-resolution conversion should consider a more capable controller after verifying the exact ADC specifications.
Recomendado
Educational and Prototype Electronics
The MC68HC908KX2CP is useful for educational and prototype work involving 8-bit embedded control, serial communication, timing, and analog measurement. Its 16-PDIP package is easy to insert into a solderless prototype board and remains convenient for experimenting with firmware and peripheral behavior. The 2 KB Flash capacity encourages tightly scoped projects and makes the device suitable for teaching basic embedded-system concepts. Students should consult the manufacturer documentation for memory organization, assembler or development-tool requirements, reset behavior, and pin multiplexing rather than relying only on distributor summaries.

Notas de diseño
Do not treat MC68HC908KX2CP and MC68HC908KX2CP-MO as interchangeable based only on the shared base number. The supplied distributor snippets assign 8 MHz to the exact target and 32 MHz to the -MO listing. Verify the complete ordering code, clock rating, package, pinout, and manufacturer documentation before programming or substituting either part.
The verified package is 16-PDIP, so preserve the original through-hole footprint, pin spacing, and connector orientation. Check the exact datasheet pinout before routing because the supplied results do not provide pin names or electrical limits. Avoid assuming that a related 68HC908 suffix has identical multiplexing, reset, oscillator, or power-pin assignments.
Supply-voltage limits and I/O ratings were not included in the verified search data. Determine the acceptable input voltage range, output-drive limits, reset requirements, and decoupling recommendations from the MC68HC908KX2CP datasheet before connecting external sensors or actuators. Add appropriate protection and interface circuitry where a field-connected signal could exceed the MCU limits.
Información de cumplimiento
The supplied search results do not provide verified compliance information for the exact MC68HC908KX2CP. A related distributor page mentions RoHS for MC68HC908KX2CP-MO, but that statement is not applied to this exact target MPN.
