Device Structure

44-pin QFP surface mount package, compact square form factor. Suitable for automated PCB assembly. Pinout supports 32 I/O channels, integrated data conversion and connectivity pads.

Performance Characteristics

Runs at up to 8MHz for efficient processing of 8-bit operations. High memory capacity for code and data storage. Fast communication with integrated interfaces. Reliable operation between -40°C and 85°C, suitable for industrial environments. RoHS-compliant materials ensure environmental safety.

Application Environments

Embedded controls in industrial automation, basic data acquisition systems, simple communication devices, LED display driving, power management subsystems, and compact consumer electronics. Works well in environments requiring stable operation across wide voltage and temperature ranges.

Selection Guidelines

Use this MCU when you need solid 8-bit performance, moderate program memory size, and multiple communications options in a single chip. Best for legacy HC08 designs, applications with moderate complexity, or projects that prioritize cost-effectiveness and reliability over high processing power. Not recommended for new designs since the part is not for new developments.

Usage Considerations

Ensure supply voltage stays within 2.7–5.5V. Provide proper PCB layout for surface mount QFP packages, adhering to thermal and moisture requirements (MSL 3). The part lacks built-in EEPROM, so long-term non-volatile storage relies solely on flash. Use onboard ADC channels for simple sensor interfacing. Check intended oscillator configuration, as only internal oscillator is provided.

Potential Equivalent/Replacement Models

No direct equivalent listed in the provided information. For new designs or if this part is unavailable, consider similar MCUs from the NXP HC08 series, such as MC908GP32, MC908QB8, or MC908JL8 for lower memory sizes. For modern alternatives, look into NXP S08 or Kinetis 8-bit and 32-bit MCUs.
