The 42-pin SDIP (0.600-inch row spacing, 15.24 mm) and PDIP packages are through-hole, so the board assembly uses wave solder or hand-solder — no reflow profile needed, but the larger footprint limits board density compared to a QFP or QFN. Thirty-two general-purpose I/O pins handle external peripherals and control signals. Six-channel 8-bit ADC reads analog inputs like potentiometers or temperature sensors. ## Peripherals: POR and PWM for power-on and motor control On-chip peripherals include Power-On Reset (POR) and Pulse-Width Modulation (PWM). POR eliminates an external reset supervisor IC if the supply ramp meets the POR threshold timing. The PWM module drives DC motors, LED dimming, or class-D audio — the 6 MHz core clock limits the PWM carrier frequency to about 23 kHz at 8-bit resolution (256 counts), which is audible but usable for motor speed control.","metaTitle":"NXP MC68HC908BD48I 8-bit MCU, HC08 core, 6 MHz, 48 KB Flash","metaDescription":"NXP MC68HC908BD48I 8-bit microcontroller, HC08 core at 6 MHz, 48 KB Flash, 1 KB RAM, USB + I²C, 42-PDIP.
