MC908AP64CBE Overview
An HC08 microcontroller is a single-chip embedded controller within the broader semiconductor and embedded-processing hierarchy. It combines a CPU core, flash program memory, data memory, digital I/O, timers, and communication or control peripherals on one integrated circuit. This integration allows a product to execute control firmware and manage sensors, switches, actuators, or communication interfaces without requiring separate memory. The MC908AP64CBE is therefore a general-purpose 8-bit embedded MCU rather than a discrete logic IC or analog regulator.
The verified product data highlights a 64K x 8 flash organization, meaning 64K eight-bit storage locations, and an 8MHz operating speed. The 42-pin PDIP package supports conventional through-hole PCB assembly and provides the external signal and power connections required by the HC08 device family. The verified distributor descriptions also associate the part with a 10-bit ADC application feature, although detailed ADC operating conditions are not provided in the supplied data. Do not infer resolution, accuracy, or conversion timing beyond that explicit 10-bit ADC association.
MC908AP64CBE can be used in industrial control, appliance control, instrumentation, low-cost embedded products, and legacy embedded systems where a dedicated 8-bit controller is preferred over a higher-performance processor. The 64KB flash capacity provides room for firmware and application logic, while the 8-bit CPU architecture can simplify resource-constrained control loops. Engineers should verify the complete pinout, supply limits, clock configuration, memory map, and peripheral behavior against the official Freescale or NXP datasheet before finalizing a new design.
Because this is a legacy DIP MCU, PCB decisions should be driven by package outline, pin numbering, programming method, and signal requirements rather than only the base part number. A distributor listing may show the HC08 family, flash size, speed, and package, but it does not replace a full manufacturer datasheet for production qualification. Confirm authorized sourcing and current lifecycle status during procurement.
This page consolidates verified distributor specifications, sourcing context, and practical replacement-selection guidance for MC908AP64CBE.

Typical Applications
MC908AP64CBE is suitable for 6 applications: Legacy industrial control, Appliance and household control, Simple instrumentation, Motor and relay control, Educational and prototype systems, Legacy product refresh.
Legacy industrial control
The MC908AP64CBE fits legacy industrial-control boards that require a deterministic 8-bit controller, 8MHz operation, and 64KB of retained program memory. Its HC08 architecture and 42-pin PDIP package make it relevant for maintaining equipment built around the original MCU rather than redesigning the controller. The 10-bit ADC association can support simple analog supervision when the channel count, reference, and timing requirements are confirmed from the datasheet. Verify supply limits, timer resources, and I/O multiplexing before updating an existing production board.
Recommended
Appliance and household control
MC908AP64CBE can be used in appliance controllers, keypad interfaces, relay-control boards, and household equipment that stores firmware in on-chip flash. The 64KB (64K x 8) flash organization provides a defined firmware-storage target for control logic, while the 8-bit HC08 CPU is appropriate for simple sequencing and discrete I/O. A DIP package also supports repair-oriented and through-hole prototypes. Before release, confirm that the controller has the required I/O count, timer channels, memory map, and programming workflow for the target appliance.
Recommended
Simple instrumentation
The MC908AP64CBE is a reasonable candidate for compact instrumentation where a small controller must coordinate switches, displays, sensors, and status indicators. The verified Mouser listing explicitly associates the device with a 10-bit ADC, making it potentially useful for basic analog measurement, but channel count and conversion performance are not supplied. Engineers should establish the analog signal range, reference strategy, sampling rate, and calibration requirements before selecting the MCU. The 8MHz clock provides a clear timing basis, while the 64KB flash capacity supports device firmware.
Recommended
Motor and relay control
MC908AP64CBE can serve as the supervisory controller in relay, solenoid, and small motor-control systems where the application is dominated by discrete sequencing rather than high-bandwidth processing. The 8MHz operating specification and 64KB flash capacity support embedded control firmware, while the DIP package is convenient for legacy through-hole assemblies. Confirm the device's timer outputs, pin multiplexing, voltage domains, and protection requirements in the official datasheet. Do not assume that the 10-bit ADC alone is sufficient for current sensing or closed-loop motor control.
Recommended
Educational and prototype systems
The MC908AP64CBE is suitable for educational embedded-controller labs and through-hole prototypes where students or engineers need direct access to a recognizable HC08 control platform. Its 42-pin PDIP package is easier to inspect and probe than a fine-pitch surface-mount device, and the 8MHz specification provides a straightforward clock target for timing demonstrations. The 64KB flash capacity can host moderately structured firmware, but the supplied data does not define RAM or programming-tool requirements. Use the official HC08 toolchain and pin documentation for successful setup.
Recommended
Legacy product refresh
MC908AP64CBE is appropriate for a product-refresh project intended to preserve the original HC08 firmware and 42-pin through-hole board architecture. The verified identity of 8-bit architecture, 8MHz clock, 64KB flash, and 42-pin PDIP makes it possible to identify the original component during reverse engineering or spare-parts sourcing. A direct replacement should still be checked for electrical timing, pin multiplexing, flash-programming, and peripheral changes. The supplied data does not establish lifecycle status or long-term supply guarantees.

Design Notes
Do not treat a related MC908 model as a confirmed drop-in replacement. The supplied cross-reference results identify MC908AP16CBE and MC908AP8CBE as comparison-related parts, but they do not establish identical pin multiplexing, flash organization, RAM, timers, ADC channels, or programming behavior. Compare the manufacturer pinout and memory map line by line, then validate reset, interrupt, and timing behavior on hardware.
For an existing MC908AP64CBE board, preserve the 42-pin PDIP footprint and verify pin numbering against the official package drawing before ordering a substitute. Through-hole DIP layouts are sensitive to row spacing, drill size, pad diameter, and pin-1 orientation. The supplied data confirms a 42-pin PDIP but does not provide complete dimensions, so do not derive a footprint from a generic DIP template without the manufacturer drawing.
The verified data does not provide supply-voltage limits, absolute maximum ratings, or current specifications. Confirm the allowed VDD range, I/O voltage domains, reset thresholds, and power sequencing before connecting external signals. A board-level power budget should include MCU supply current, pull-ups, sensors, relay drivers, and any interface circuitry; those values must come from the relevant device datasheets rather than from the MC908AP64CBE distributor snippet.
The supplied results do not state operating temperature or thermal resistance. For a new enclosure or industrial installation, verify the manufacturer temperature rating and calculate worst-case dissipation from the actual supply voltage, I/O load, clock activity, and peripheral use. Because the device is a legacy through-hole MCU, thermal performance depends strongly on PCB copper, airflow, and nearby heat sources; no thermal conclusion should be drawn from the package name alone.
Keep clock, reset, and programming-related traces short and route them away from noisy switching nodes. Confirm the required decoupling and external component values from the official datasheet, because the supplied search data does not specify them. When connecting relays, motors, or high-current loads, use separate return-current planning and appropriate protection; the MCU's 10-bit ADC association does not establish that the device can directly measure high-voltage or high-current power stages.
Compliance Information
The supplied verified data does not include environmental, lead-free, halogen-free, conflict-minerals, or automotive-qualification statements. These fields remain unknown rather than assumed.
