The HC08JK and HC08JL Families are members of the low cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08 Family is based on the customer-specified integrated circuit (CSIC) design strategy. All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and available with a variety of modules, memory sizes and types, and package types.

Instructions:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (2.7V to 5.5V).
   • Use a stable power source to avoid voltage fluctuations.

2. Frequency Operation:

   • The device operates optimally between 8 MHz and 50 MHz. Ensure the clock signal is stable and within this range.

3. Current Handling:

   • Do not exceed the maximum input current (20 mA) or output current per pin (40 mA) to prevent damage.
   • If higher currents are required, consider using external drivers.

4. Power Dissipation:

   • Keep the power dissipation below 600 mW to avoid overheating. Use appropriate heat sinking if necessary.

5. Temperature Considerations:

   • Store the device in temperatures between -40°C and 85°C.
   • Operate the device within the same temperature range to ensure reliable performance.

6. Leakage Current:

   • Monitor input and output leakage currents to ensure they do not exceed 5 μA to maintain optimal performance.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Follow proper ESD (Electrostatic Discharge) precautions when handling and soldering the device.
