FAQ

What is the maximum operating frequency of the S9S08QD2J1CSCR?

The S9S08QD2J1CSCR features an HCS08 CPU core with a maximum bus frequency of 16 MHz. This speed is achieved using the internal clock source (ICS) with its frequency-locked loop (FLL), which operates reliably across the full automotive temperature range (–40°C to 125°C) and supply voltage (2.7–5.5 V). The S9S08QD2J1CSCR does not require an external crystal to reach this frequency.

Does the S9S08QD2J1CSCR support in-circuit debugging?

Yes, the S9S08QD2J1CSCR supports single-wire background debugging (BDM) via the BKGD/MS pin. It includes breakpoint capability for one active breakpoint during in-circuit debugging, plus two additional breakpoints managed by the on-chip debug module. This allows real-time code inspection and firmware development without requiring dedicated debug headers or JTAG interfaces.

What are the power-saving capabilities of the S9S08QD2J1CSCR?

The S9S08QD2J1CSCR supports Wait mode plus three Stop modes (Stop1, Stop2, Stop3), enabling aggressive power reduction. In Stop3 mode, current consumption drops below 1 μA with selected wake-up sources enabled. The device retains RAM contents and supports wake-up from multiple sources including IRQ, KBI, RTI, and ADC end-of-conversion - making it ideal for battery-powered or energy-conscious applications.

Can the S9S08QD2J1CSCR operate without an external crystal?

Yes, the S9S08QD2J1CSCR operates fully from its internal clock source (ICS) module, which includes a frequency-locked loop (FLL) and precision-trimmed internal reference. This eliminates the need for external crystals or resonators while maintaining ±2% frequency accuracy over temperature and voltage - a key advantage for space- and cost-constrained automotive and industrial designs.

What is the ADC configuration of the S9S08QD2J1CSCR?

The S9S08QD2J1CSCR integrates a 4-channel, 10-bit successive-approximation ADC with internal bandgap reference, temperature sensor channel, and automatic compare function. Conversions can be triggered by software, the RTI counter, or external events. The ADC supports asynchronous clocking and delivers stable measurements across the full operating range without external reference components.
